It's easy to roll out, and their understanding of our business made it seamless
One aspect we value about iboss is its simplicity. Their customer service is brilliant, and they are super responsive and knowledgeable. It's easy to roll out, and their understanding of our business made it seamless. We were impressed by the solution's mental health function, which can detect if someone needs help. It scans what users are browsing and flags warning signs so we can check to see if they are okay. We've had to use it a couple of times. The user interface is highly intuitive. Our IT team picked it up with minimal training. It's arranged so that it's easy to find where things are. Another advantage is the single pane of glass console, which gives you visibility into what's happening. We're not fully there yet because we haven't implemented zero trust, but we're excited about the possibilities from the demos we've seen. We launched a POC of iboss' ChatGPT Risk Protection feature two weeks ago. AI is a great tool, but you need to be careful what you put into it. My biggest fear is employees inputting sensitive corporate information or customer PII data into one of these chatbots. I was impressed by our trial of the feature. It's exactly what we wanted. Now, when a user goes to ChatGPT, there's a banner warning them not to share information, and we can block conversations containing customer data like bank details and email addresses. I don't want to stop people from using it, but we need visibility. We've only tried it on a test group of 15 people. You can configure it to look for specific keywords or integrate it with your DLP policy if you have that configured

A stable solution with an intuitive interface and quick customer service
I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

User access management and threat prevention are enhanced with user-friendly controls
The best features Zscaler Internet Access offers include application control, tenant segregation, and PoP center regions which have low availability zones. The internet access is very successful and bandwidth speed is excellent. It also has application-based control, URL-based control, and SSL inspection capabilities, which are very useful. Additionally, the in-depth CASB segregation is very beneficial to us. One unique feature I found helpful is the tenant level restrictions, which we use to only access our organization's tenant level mail IDs, drives, and specific tenant level access while restricting public access. Zscaler Internet Access has positively impacted our organization as we have noticed substantial outputs and income. It has improved our security environment control and endpoint protection. It prevents numerous web attacks through its AI/ML incorporated capability which identifies malware, threats, and viruses. It has a toggle button to enable features entirely at the tenant level for all users onboarded into Zscaler Internet Access, resulting in much better outcomes.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The console is cloud-based, which is something I really appreciate."
"From a use-case scenario, what I like the most is the plug-in. I like the fact that we can do the filtering of these devices offsite independent of the network they are connected to, and we do not have to have traffic coming back inside our network."
"We were impressed by the solution's mental health function, which can detect if someone needs help. It scans what users are browsing and flags warning signs so we can check to see if they are okay. We've had to use it a couple of times."
"Content filtering is the most useful feature of iboss."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"Its initial setup was straightforward."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"Our primary use case for this product is DLP,"
"The scalability is good in Fortinet FortiGate."
"Fortigate's most valuable feature is that it doesn't need a push policy when writing rules."
"FortiGate Next Generation Firewall's design is good...I am very impressed with the product's stability."
"It is easy to manage, and it doesn't need much knowledge from the team. It is a stable device, and there are many features that are included out of the box."
"It offers web filtering capabilities at a more affordable price compared to other solutions like PSMs or NETGEAR."
"We can detect any attack of viruses or malware at the first point of contact."
"Fortinet FortiGate's reliability is valuable."
"The most important features with FortiGate are the web filter and application controls. We can control our internet usage and use the web filter for application purposes."
"Zscalar Internet Access is for Internet security, like an Internet security gateway. I like how it runs seamlessly in the background with a single sign-on. The controls you can have on devices for Internet security are good, and it doesn't impact speed wherever you're connected. Overall, I think it's very good so far."
"The security is excellent."
"Zscaler Internet Access's best feature is the granular policy controls."
"The product's initial setup phase is a bit easy, as one doesn't need high technical expertise."
"All internet access flows through the Zscaler proxy, regardless of whether people are in office or remote. I have greater control site access and I minimize the number of compromises that we experience to almost none."
"The initial setup is very straightforward."
"One on the main benefits is protection all time from anywhere."
"Zscaler Internet Access has helped us reduce the time that we spend managing security policies by about four hours a week. We can use this time to focus on other things, especially the IT team."
 

Cons

"Sometimes when you call in support, you get someone who is just following a sheet. It feels like a runaround. You feel that you are running into that support wall."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"I would like to see the licensing aspect improved because there is a feature we were yearning to use, the bandwidth monitoring feature, but it's licensed separately."
"The pricing could be reduced or include the first year warranty."
"I see problems with the licensing. If I have to add a new feature, we need to add a license."
"It would be ideal if they had some sort of GUI interface for troubleshooting and diagnostics."
"The improvement is related to logs. Instead of the CLI, we should be able to have more insights into the logs of the firewall in the GUI."
"FortiGate IPS is somewhat pricey compared to other solutions. There is also room for improvement in terms of the radio signals. The FortiGate WiFi has a relatively short range. I've found there is a lag in its zero-day malware response that could be better, and FortiGate could integrate better with other brands of equipment or identity management solutions."
"Fortinet FortiGate could improve the user interface. There should be more functionality and options through the GUI."
"It is quite new for us, and we need to go more in-depth into the monitoring tools. It provides different features that we need to do what we want. So far, it is okay for us. In terms of improvement, in the future, they can provide a faster implementation of features. Some of the features are first available in other solutions. Fortinet sometimes takes a little bit longer than other solutions, such as Check Point, to implement new features."
"One feature I am missing is the ability to connect automatically to internal monitoring systems."
"I would like to see more training and video documentation."
"In terms of usage, here in the GCC, it's still growing a growing market, so the combination of DLP, data leak prevention, to a certain extent is fine. But what it requires is user-based access or role-based access. The solution needs to grow into that, which definitely takes time. There's not an easy way to integrate it, when you have a cloud-based solution."
"Sometimes it's not easy to use during large deployments of workstations."
"Another thing that I would like to see is if Zscaler could have a separate product for direct access. I looked at a private access solution, but I understand there's a separate product that isn't integrated with this."
"We'd like for them to include some sort of antivirus tool."
"If they can also integrate with the multi-factor authentication to prompt users to do another, second-factor authentication, that would be ideal."
"There are many functionalities in Zscaler Internet Access that need improvements, such as an advanced firewall and logging capabilities to track calls."
 

Pricing and Cost Advice

"The overall pricing for iboss is very competitive and transparent."
"It is expensive compared to one of its competitors."
"It is not expensive, and it is also not cheap. iboss is priced right in the sweet spot for the number of features it offers."
"We had the cost of purchasing a new appliance along with the implementation and licensing costs. However, the following year, the cost of just licensing was similar to what was paid the previous year for a new appliance along with the implementation and licensing costs."
"It is probably in line with other solutions, but I do not deal with the financial side."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"The price is highly competitive when compared to other brands that offer similar functionality."
"Our licensing costs are on a yearly basis."

"It is around $50,000 per month."
"The price of Fortinet FortiGate is reasonable."
"The price is okay, so far so good."

"We have found the solution to be expensive."
"It is a few pounds per user per month."
"Price-wise, the tool is reasonable compared to the other products in the market but it is not a very low-priced tool. The solution does provide value for money."
"The pricing is fair based on its competitive market."
"Zscaler is transparent about its pricing model."
"If we need any extra features, the price will increase."

Sophos UTM vs. Fortinet FortiGate
I have used both Sophos and Fortinet products in production and I have found the Sophos UTM appliances (hardware and virtual) to be a better fit most of the time -- with a few caveats which I will touch on below. In both instances, the transition from TMG will be mostly straightforward. The main…

IT really depends on the type of business you had currently. These days almost all security vendors are offering Virtual Appliances so it's a preference based decision. Almost all vendors are offering basic features with some add-ons / additional features with differences among others competitors. Look at 1. FortiGate, 2. Cisco Meraki, 3. SOPHOS Products they all provide you flexibility to have...

There are several factors to consider: · In-house expertise to manage a physical firewall · Number of locations requiring a firewall · Current and planned linkage between office locations · Value of the information you want to protect I’m personally a fan of on-premise physical firewalls for high $ information to protect. However, if the $ risk is not particularly high, your in-house expertise to manage firewalls is low, and you have multiple locations to protect, I would recommend a security gateway service with VPN connections between your offices and the location of the security provider. I cannot recommend one supplier over another. If you choose to go with a physical firewall, Fortigate has a good reputation. Regards,

Depending what is your goal and where offices are based. When you want to protect your users in offices, then you would want to have kind of perimeter firewall (usually appliance) - standard (old) way. Fortinet is affordable and OK. When you wan't better check Palo Alto Networks. In case your offices are close (in milliseconds) to Zscaler cloud then you could also use this. Ask them to share information of their "cloud" locations and measure RTT from your offices. Note that all your traffic will go via Zscaler cloud (privacy, confidentiality). With Fortinet or similar appliance, you have possibilty to have VPN for your users with home office. Not sure when it's feasible with cloud solution from Zscaler. Like said really depends on where you are, what kind of business you are doing.
