Fortinet FortiGate Reviews

We've deployed FortiGate on some customer premises. We've also deployed other Fortinet products, such as FortiMail and FortiManager. We often bundle Fortinet devices. We use FortiGate as a firewall. It is for security and protection. 

The solution has helped our clients secure their network efficiently. It offers security across multiple sites and helps monitor traffic effectively.

It's very good and very stable for businesses. It works very well. 

The UI is better than the alternatives. 

We like using Fortinet devices. They integrate well with one another.

Fortinet provides good visibility and segmentation.

Fortinet's devices are purpose-built to operate in various environments. It operates well across clouds. We can run Fortigate as an MSP.

It helps with intrusion prevention specific to various environments. It provides us with details about the traffic for better monitoring. 

FortiGate has helped reduce the risk of cyberattacks that might disrupt our client's production. 

The product provides policies for strict monitoring to make the network secure. If something hits against a policy, it will be blocked.

We'd like to see the product offer higher discounts to users. They should offer special pricing to premium partners and customers. 

The company has been using the solution for the last five or so years. I've maybe used it for three years.

The stability depends on the FortiGate model. You need the right model for the amount of GB traffic. If a customer deploys a smaller model on more traffic, there may be issues. Otherwise, it handles traffic well. Overall, it's a stable solution. I'd rate stability nine out of ten. 

Our clients are quite sizable. One of them is one of the biggest telecoms in our country. We also have smaller customers that deal with smaller FortiGate models. We have a variety of customers of different sizes from around the country.

It's a scalable solution. I'd rate it nine out of ten. 

Technical support is good. They offer very accurate solutions. We learn a lot from them. We're happy with their level of service. 

We typically deploy the solution to our client's VMs. The deployment sometimes takes about a month. We have a team of 12 people who work on the FortiGate side. 

Their services are good, and we are happy to work with them, however, the pricing could be cheaper. 

We're a Fortinet partner. 

If we have the option of which firewall to choose, whether Fortinet, Cisco, Juniper, et cetera, we will choose Fortinet. We're very comfortable with their devices. We have a very skillful team, and we've become very comfortable with Fortinet. They have good support as well.

I'd rate the solution ten out of ten. 

We use the solution to secure our entire data, limiting user traffic from within the system, which needs to be assessed to be secure. That is the main motive behind choosing the solution.

Suppose I don't want to pay for the users. We would have done some whitelisting and content filtering on the FortiGate web gate. Based on the policies, any user traffic is filtered through the secure gateway.

It's a flexible solution.

What happens in FortiGate is that a lot of bugs come on a system-by-system basis, like when Fortinet launches new firmware in FortiGate. Most software launches with known or unknown bugs. When we go for upgradation, even after running a bug scoping exam, we don't know whether the BIOS for which we are upgrading would affect the end user. We don't know how the FortiGate firmware will behave in your environment. Whatever the known bug, FortiGate lists it in their documents, but you never know how the problem will impact your environment. That's a major disadvantage of FortiGate because, somewhere, it's very unstable.

Another issue is how deduplication services don't work reliably after enabling deduplication on Fortinet. When they launch any new firmware in the future, they have to ensure firmware functions.

I've worked with Fortinet FortiGate SWG for more than ten years now.

I rate the solution's stability a seven out of ten.

I rate the solution's scalability a seven out of ten. We have around 700 users on the platform.

If any issues arise, we have to log a ticket with Fortinet. By default, they log all the tickets in P3 or P4 priorities. For P1 or P2, they ask to call us on their phone numbers and lines. Whenever we try to call on the phone for any P1 or P2 issues, the next time, the number gets busy, or the email is unavailable. That's why

I feel the support is not up to the mark, and they must work on it.

Neutral

I rate the solution's initial setup a seven out of ten. The deployment time depends on the scenario, such as your infrastructure size. To deploy the solution on a cloud, you have to buy it from the marketplace and deploy it on the cloud. But after that, you have to do a lot of configurations. That depends on the size of the operation.

One person is more than enough to implement the smaller version of the solution. But if the organization is bigger, with more than 500 or 600 users, we would need three to four people.

Fortinet is priced low.

We are exploring Netskope and evaluating it for the future.

I recommend Fortinet FortiGate SWG because it is flexible and cost-effective. I rate it an eight out of ten.

Our customers use these devices as security devices, and we sell these devices to our customers. We also use it ourselves. We have the entire lab, and we use some of the functions in our local network.

It protects our customers' networks from viruses and threats.

The firewall, IPS, and VPN functions are the most valuable features. The antivirus functions are also good.

It works very well. It has a lot of different functionalities. Its cost is also fine for our customers.

In some cases, its initial setup could be hard for customers.

I have 10 to 12 years of experience with these devices.

Their devices are quite stable. We have not had any problems with the operating systems or maintenance of subscriptions. It is a robust device.

In most cases, they work very fast. It also depends on the device they are supporting. In the case of FortiGate, we do not have any complaints, but when we had to buy the FortiADC solution for one of our customers, we faced quite a few difficulties with technical support. I do not know why, but it could be that some devices are supported by different teams in Fortinet. We had difficulties with FortiADC, but we have not had any problems with FortiGate. I would rate their support for FortiGate a nine out of ten.

Positive

We worked with Cisco and Check Point firewalls. We worked with Cisco ASA for a long time. We worked with it for about five years, and we were happy with it, but it was old-fashioned. We went to Fortinet and started working with this company. 

FortiGate has good security functions and high-level technical documentation. Their documentation is very easy to understand. 

FortiGate's performance is also better than Cisco ASA. It has 10 VDOMs. It is a great function because you can add virtual functions for different groups in your network. It is quite useful.

It is deployed on-premises. Our customers prefer to deploy not only Fortinet devices but all security devices on-premises. They rarely use cloud licenses. Some customers only buy it from us, and for some customers, we also set it up.

Its setup is easy for us, but not every company wants to use our service for setting it up because of the cost. They prefer to install it themselves. In some cases, it could be hard for them.

In terms of the implementation strategy, we first try to understand what problem a customer wants to solve by using FortiGate. We collect a lot of information about a customer's network, such as protocols and devices being used. We try to prepare this device in our local lab. We preload the device and send it to the customer, and then we finalize the installation in the customer's building.

We have very technical staff, and we do not have difficulties with installations. We have had situations where customers do not have much experience with it, and then we recommend them to go for certain features such as IPS, antivirus, etc. 

The deployment duration depends on the size of the environment, but generally, it does not take more than one or two months. 

Generally, two to three people are required for the deployment.

For maintenance, our customers have technical staff. They regularly check and ensure that all the functions are working. We are glad to help them if they need any help.

We have seen an ROI. We have bought a lot of these devices, and we have had a good experience with them. It has saved us a lot of money.

It is quite affordable for our customers. There is a separate cost for IPS, antivirus, web filtering, and other features. They have a great choice of licenses. You can go for the license that you want, which is quite useful.

You have to buy a support license for FortiCare. In most cases, people buy the UTM bundle that comes with IPS, web filtering, and FortiCare. 

They are on the right path. They have improved a lot over the past 10 years. Fortinet is one of the leaders in security devices along with Cisco, Palo Alto, and Check Point.

I would rate Fortinet FortiGate a nine out of ten. It is stable. It has quite a lot of features, such as IPS, VPN, etc. It is affordable for our customers. It is a good choice.

We primarily use the product to enhance our network security infrastructure. It monitors and investigates inbound and outbound traffic across our organization, ensuring comprehensive security coverage.

one interface to manage all our fortinet product

The product's most valuable feature is the ease of deploying IoT security with a single click. Additionally, the frequent updates to the online database ensure that our security measures are always up to date, enhancing our protection against emerging threats.

One area for improvement is the licensing policy. If support licenses are not renewed, the product's functionality ceases, which can be disruptive. 

Integrating more advanced threat detection capabilities utilizing artificial intelligence would be highly beneficial in future releases.

I have been using FortiGate for around 15 years.

The solution is highly stable, with minimal disruptions. I rate it a ten out of ten for stability.

Once deployed, the product scalability is constrained, requiring appliance upgrades for increased port capacity.

The customer support team is responsive but relies heavily on external partners for frontline assistance, which can lead to delays in critical situations.

Neutral

aruba, cisco

the move was decided for the convinence of the fortinet's management interface

The initial setup is straightforward for those with a technical background in network security. However, configuring the system requires a good understanding of the product.

We implemented FortiGate with our technical team, which has extensive experience with network security solutions.

Since implementing FortiGate IPS, we've seen an approximately ten percent reduction in operational costs, largely due to consolidating security measures onto a single platform.

The platform offers a reasonable price point compared to its competitors.

Before opting for FortiGate, I evaluated several competitors, including Palo Alto, Checkpoint, WatchGuard, Barracuda, SonicWall, and Sophos. 

FortiGate is a solid choice for organizations seeking comprehensive network security. Ensure your team has the technical knowledge required for effective deployment and ongoing management.

I rate it an eight. 

We are currently using Fortinet FortiGate firewall instead of Cisco.

The best features of Fortinet FortiGate include good functionality, though the licensing cost is a bit higher. Their response time and throughput are very good advantages.

Some websites or proxies are not embedded in the correct category, and we need to update the Fortinet FortiGate database because numerous websites are appearing every day. Some websites are embedded in the wrong category which we can block, resulting in everything being blocked, so this database needs improvement.

The licensing cost should be more affordable than it is currently. The SD-WAN of Fortinet FortiGate needs improvement; when we create a group address, sometimes the rule doesn't work properly.

Regarding the Fortinet FortiGate database issues, some websites or categories that should be classified as proxy are in different categories. When we open that category due to some other website that needs to be accessed, some proxies are also opened. The FortiGate web filter categories need to improve their database for better control.

I joined the current company two and a half years ago, and we have been using Fortinet FortiGate for about three or four years.

I have only required technical support from Fortinet FortiGate once or twice in two and a half years, and I have had a good experience with them. Their technical team is very knowledgeable. Their response time is very good; whenever we open a case, they respond promptly.

One issue I encountered was with FortiToken, which we configured on the admin profile. While managing four firewalls, I discovered that FortiToken was not enabling due to an issue on one firewall. I opened a case, but it has not been resolved yet. Despite this, my overall experience with them has been very good.

Neutral

In my previous company, we were using Sophos, which had better licensing costs compared to Fortinet FortiGate.

We are not using enhanced SD-WAN Cisco SD-WAN; we are just using the SD-WAN for load balancing.

We are using Ubiquiti for wireless. One drawback about UniFi is that it lacks BeamFlexing, which is available in Ruckus, and the AP radius or Wi-Fi signals are not as strong as Ruckus. However, UniFi is still a good option, though not as robust as Ruckus.

Fortinet FortiGate is quite expensive, but according to the Gartner report, it ranks second or third. My experience with Fortinet FortiGate firewall has been quite good.

I would rate Fortinet FortiGate 9 out of 10 overall.

Overall, we use Fortinet FortiGate IPS for group security, managing several companies across the region via a central location in Trinidad.

It ensures that we safeguard our environment effectively.

The ease of use, concise reports, and threat identification are very user-friendly and valuable.

There are no areas that need improvement at this point in time.

I have used FortiGate IPS for about two years.

So far, we have had no issues with stability. 

FortiGate IPS seems to grow with us as we grow. We are on the latest edition, and it is fairly easy to maintain going forward.

I do not normally interact with customer service, yet I had a very good conversation with them the other day. I would rate the experience a ten out of ten.

Positive

The setup was done by the infrastructure team, including four network admins and one infrastructure security person. The initial setup appears to have been straightforward based on indications.

We haven't implemented it for ROI benefits but rather for intrusion detection. It's just to make sure that we safeguard our environment.

FortiGate is slightly more expensive. CrowdStrike is offering better rates, which is something you need to look at.

CrowdStrike and other vendors have more competitive pricing, and CrowdStrike is currently number one in the quadrant while FortiGate is ranked lower.

I would recommend this solution to others because it is a good product. Overall, I would rate it nine out of ten. It ensures security and is easy to use.

I'd rate the solution nine out of ten.

Since we are going to implement a payment gateway, digitalizing our payment to the vendors, where they can upload their invoice, we think it is really necessary to upgrade our network from the potential threat. So, we use Fortinet FortiGate IPS to address this.

Having IPS helps in ensuring that our network is protected from potential threats, which is crucial as we implement our payment gateway.

My IT team has not had any complaints and finds Fortinet FortiGate IPS quite smooth. We also get yearly updates and training from the vendors.

Pricing is one of the factors that need improvement. Maybe they can offer a smaller scope for a cheaper price for smaller organizations.

We have been using Fortinet FortiGate IPS for about three to four years.

I rate the stability of the solution as nine out of ten. We have not experienced any bugs, glitches, or downtime. It is stable.

I rate the scalability of the solution as nine out of ten.

I rate the customer service and support as nine out of ten.

Positive

The initial setup took about two to three weeks, with everything completed within one and a half to two months, considering we have multiple locations.

My IT team, which is small (about three to five people), handled this.

Pricing is expensive compared to other solutions. I would rate it as nine out of ten in terms of expense.

I recommend Fortinet FortiGate IPS to others due to its stability and effectiveness.

I'm managing security rules, bandwidth for the internet, switches, and fifty access points. Everything, including the network in Afghanistan, is managed from there, and it's something critical for us.

FortiGate's ability to perform as expected and fulfil our needs has been the most compelling feature for network security. FortiGate has proven to be secure and effective in terms of threat intelligence, as it alerts us about external login attempts and suspicious scripts, contributing to our system's overall security.

FortiGate can improve its token system, as it requires a purchase before use. Additionally, the VPN system could be more efficient, especially regarding VLAN passing through, which is currently a limitation. Another suggestion for improvement would be better timezone coordination for customer support. Currently, there are issues with calls coming at inconvenient times due to timezone differences. Another area for enhancement could be the response time for support tickets, as there is a delay of at least twelve hours, even for urgent tickets, which can be frustrating.

I have been using Fortinet FortiGate for the past three years.

It is scalable as we expand our usage of FortiGate as our company grows. We're currently using one, but we plan to use two as our network expands.

I open a ticket and communicate with the engineers when I encounter issues. Although it may take some time, they always get back to me with a resolution. There are mainly due to these issues with time zone coordination and response time.

Neutral

The setup process for FortiGate depends on the complexity of your network. For simpler setups, a user-friendly interface is easy to use. However, for more advanced configurations, it may require expertise. Integration into the ecosystem is neither too easy nor too complex.

The maintenance process is relatively easy.

Regarding return on investment, I believe FortiGate is worth the money. It has helped us stay safe, and considering what we are paying for such a system and service aligns well with our expectations and financial goals.

The price of FortiGate is reasonable as I plan to buy new switches. The initial gadgets are already booted, and the pricing seems normal on the market. As for additional costs, I haven't subscribed to many extra features, so I'm only using what I need. Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us.

Overall, I would rate the solution an eight out of ten.

FortiGate is a hardware firewall that we deploy for our customers. I work on the system integration team and install whichever solution the clients choose. We also provide support, including maintenance and service. The customers contact us if they have any problems. 

The firewalls are deployed on-premise, but you can also implement FortiCloud, which can integrate with public or private cloud platforms. If you have five or six locations in various countries, FortiCloud can provide centralized security support for those offices.

FortiGate is on the cheaper end, and it offers good value. 

Palo Alto has a feature called WildFire Analysis that is unavailable in FortiGate. WildFire is better than a sandbox because it can address zero-day threats and vulnerabilities. It can immediately identify zero-day threats from the cloud. 

Fortinet uses a separate solution called FortiSandbox. It needs to download signatures to identify malware, which takes significantly longer. WildFire is a cloud-based platform that collects threat information from users worldwide. 

I have used FortiGate for eight months, but I have worked with Fortinet products, including FortiManager, for three years. 

I rate FortiGate nine out of 10 for stability. 

I rate FortiGate nine out of 10 for scalability. Fortinet sells models that can accommodate more people. You can choose a cheaper model if you only have 20-30 users, but you will need to spend more money for a FortiGate solution that covers 5,000. 

I rate Fortinet support eight out of 10. Sometimes, the Level 1 support can't fix the issue, so it needs to be escalated, and we can't get help until the next day. Otherwise, it's okay. Their frontline support can fix most basic issues, but we may need to wait a day or two for special problems. 

Positive

I also deploy Check Point and Palo Alto hardware for my clients. Check Point has been in the Indian market longer. Palo Alto came into the picture about three or four years ago. 

In my opinion, Palo Alto is the better solution. It has WildFire Analysis, and you can configure virtual routers within the system, but Fortinet is less expensive. We deploy Check Point for our larger customers. It's more appropriate for multinational companies with 10,000 employees or more. 

Deploying FortiGate is straightforward. You have to check with the customers to see if their offices use other devices. Next, you must do the basic configuration and connect all the networks available at the customer's site individually. 

The SD-WAN setup is the most time-consuming task because you need to configure the address and service objects. After that, you implement basic policies and connect the office network with Fortinet. Deployment only requires one person. 

FortiGate is on the cheaper end. The price varies depending on the model of appliance you're using. It's affordable for a university or a small business. A firewall typically has a license for three years that includes installation and support, but maintenance is separate. 

I rate Fortinet FortiGate eight out of 10. FortiGate is a solid solution, but Palo Alto is the best. I recommend Palo Alto to customers who can afford it. The second best is Check Point. When considering which firewall solution to use, you should look at your budget and the number of users. 

I used this solution while working with my last organization. I handled plain firewall deployment as well as SD-WAN deployment. 

I was providing consulting services to various Telco customers. It helped customers save on the cost of highly expensive MPLS links. With the help of Secure SD-WAN, they were able to utilize broadband or even LTE connectivity, which saves costs. That's the flexibility that Secure SD-WAN gives to various customers. In addition to saving costs, they are also able to utilize active-active load balancing, where you can have two parallel links: primary and secondary. The secondary one used to sit idle in traditional scenarios, whereas now, the solution gives you the flexibility to configure both links as active-active, so you can prioritize critical traffic from link one and other traffic from link two. At the same time, you also have the option to maintain redundancy.

Secure SD-WAN is a great way to manage your entire organization network, especially the WAN network. Customers don't have to hop to multiple places. Fortinet has a solution called FortiManager. With the help of that, you can monitor, configure, and maintain your entire organization's network. It's a very convenient option. It's a single pane of glass from a customer's point of view. They don't have to log in to individual devices, and they can see the real traffic. They can see what's coming into the network, what sort of alerts or logs are there, and what sort of applications are being consumed.

Secure SD-WAN doesn't help with tool consolidation, but it's a secure way or mechanism they provide so that if branch users are accessing the internet, they can directly break out from the branch location rather than coming back to the data center. In that way, it improves the user experience while also giving security at the highest level.

I have not interacted much with Secure SD-WAN in terms of API integration or third-party integrations. However, they have pretty good integration with the RADIUS, LDAP, and AD servers. In that way, they have everything in-built. You can make the firewall a DNS server or some sort of DHCP server. Such features are included there. From a security standpoint, they have open API integration with their own SIEM or SOAR solutions. Third-party API integration is also possible, but the API details that are exposed are very limited.

The integrated application protection provided by Secure SD-WAN is a cool feature. They have real-time scanning of the application with the help of SSL inspection. You get to see the real-time traffic of applications, and you can protect your network from harmful websites. They have a signature database for that. This data also gets refreshed. It's a direct feed that the device takes from the central intelligence.

When you have Secure SD-WAN in place, you are more secure from the outside internet. They have a flavor of SASE, but I have not worked on it.

When you have a granular view of your entire network including users and security features being enabled, you get more visibility into your network. You get to know what's coming in and going out. If an administrator sees that some traffic is being hit repetitively from a particular location, functionality is available to block a region, country, or even an IP or domain.

In terms of Secure SD-WAN reducing our mean time to resolve, in the case of issues specific to SD-WAN, I've seen instances where customers can look into the dashboard and inform the support team that this is the issue they are facing. This helps them to have some visibility into these firewalls and isolate the entire issue from the technology perspective; for example, when a wireless client is facing some sort of challenge accessing the internet, whereas some of the wired users are able to access the internet. The testing tools given in the FortiGate GUI dashboard come in handy during troubleshooting. With the very user-friendly interface, it becomes very obvious and easy for any IT guy to simply follow the workflow to resolve any day-to-day operational issues.

The security features that they have are quite good. On top of that, their licensing model is quite nice where they don't charge you anything for the SD-WAN functionality for the firewall. The routing and firewall features are also good.

The unified view that they have built into this firewall is good. Within the same dashboard, you get to see the security profiles, the type of traffic that's passing through, the top applications that are being consumed, etc.

It's also very easy to use.

I was not looking after the operations part, but sometimes, I did get engaged in some critical activities related to operations. There are some caveats in every product. Tunnel flapping was one of the major things I had seen wherein your internet link remains but your VPN tunnel is down. However, since I got a fix from the TAC team, I have not noticed it, but the customer complained a few times that they couldn't access the internet because of this problem. There were tunnel issues where there was already established connectivity, but at the kernel level, there were some issues. For example, there's a feature for auto-site connectivity wherein whenever it automatically creates a new tunnel, at the kernel level, it also creates an interface. Sometimes, that interface crashes and a new interface could not be created, which results in connectivity loss. 

Fortinet has established itself in the SMB market segment. It's doing pretty well in that space, but when it comes to the enterprise segment, they are lagging a little bit. It all boils down to the performance of the hardware. If I enable all of the security features available on my device, the throughput degrades quite a lot. If I have put 10 GBPS of throughput on a firewall and I enable all of these features available, such as IPS or UTM functionalities, the throughput comes down to 1 GBPS.

I used Fortinet FortiGate for seven months. I last used it in February of this year.

I'd rate it a seven out of ten in terms of stability.

The solution offers the option of deploying VMs or virtual machines to any public cloud, such as AWS or Azure. It provides such flexibility. If you have any application hosted in the cloud space, you can have a VM spin of the FortiGate over there and have a site-to-site tunnel established, so the scalability is there. Otherwise, at the site level, it's mostly hardware-based work. If you size it properly, then you have the option to expand. You might have chosen a low-end model because of the tight budget. In that case, it's not scalable on a specific site. However, if you have a certain number of sites, for example, if you have 400 of them and you want to expand to 500 or 1,000, there is simply a license that goes at the FortiManager level to support additional devices. FortiManager provides a single pane of management. 

I'd rate it a seven out of ten in terms of scalability.

My experience was not that rewarding. It took me around three hours in total to get a simple issue identified and fixed. I escalated it to their L3 engineer, and after that, I was able to resolve the issue. The entire process took around three hours. First, their initial level person was troubleshooting, then it went to the next level, and then it went to the highest level.

Neutral

From the security perspective, I have not used any other solution, but I did have a glance at Cisco's portfolio. Cisco Meraki is one of the solutions that you can compare it with. Others were more specific to the routing and switching domain. I know the concepts and theory of Cisco SD-WAN, but I have not used it in a real environment for any customer.

For one of the clients, it was deployed on the Azure public cloud. Initially, it was not easy. It was complex. Every product and technology requires a certain type of prerequisite, and when you have anything hosted on a public cloud, it becomes a tedious job to get things done quickly because multiple stakeholders are involved in that.

I have deployed Secure SD-WAN specifically for many customers. I find it easy, but you need one person to be at the site for remote connectivity. That person just needs to do the basic configuration. Once the device has IP reachability, you can easily discover it from FortiManager, which is the central controller. So, once you have the device on FortiManager, it takes a few clicks to onboard the device because you already would have a template in place.

The deployment duration depends on the number of sites. For a customer with ten sites, it would take a week's time because there are a lot of dependencies. It also depends on the customer's readiness and availability, but a week's time would be enough for the deployment of ten sites. If there is proper planning in place, you can also deploy 50 sites in a week, but that's something you cannot control from your side because there are a lot of dependencies on the customer and the service provider. If you have to integrate it into a customer's existing network, it becomes quite challenging to make them understand your prerequisites. There are instances where nobody is available from the customer side from the technical standpoint to help you. Those are the roadblocks, but from the solution perspective, it's quite easy to onboard devices.

The deployment can be done by one person if that person is dedicated to a single project, but if more projects are running in parallel, you would require a few more people.

It does require maintenance, which includes upgrading the operating system and installing patches. Two to three people would be enough for around 500 site maintenance but not in the 24/7 case. If it's 24/7, then nine people would be required for that.

By default, they give SD-WAN along with the firewall. They don't have separate licensing for the SD-WAN functionality. However, they have security licenses that are sold separately on a subscription basis. Customers can consume these security features to protect their users from internet traffic.

To those evaluating this solution, I'd advise doing a PoC of different vendors who are meeting their requirements. They can then decide for themselves after seeing the demo.

Overall, I'd rate it an eight out of ten. It's user-friendly. It's also good features-wise, but their support is weak, and on the architecture front, it's not true SD-WAN. It's not decoupling the control chain functionality from the device to the controller.
