Enhances web security with a single pane of glass and flexible deployment
I don't see any need for improvement; one of the really good things about iboss as a company is that they listen to customer feedback. I have suggested enhancements, and they are responsive, making changes for the better, and they do a lot of testing. To improve iboss, although we haven't used it, we considered the VPN solution that comes with the highest tier licensing, which includes DLP and various other add-ons. We prefer using another product which automatically logs you back onto your network when turning on your PC. With iboss, the connection is manual, which doesn't meet our needs. Additionally, sizing can be tricky because, although the initial recommendations may seem adequate, actual usage may require more gateways than anticipated.

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

"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"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."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"iboss is among the few products providing inline filtering where no application is needed on the device. It operates on the network side and is not device-based. This feature was one of the main reasons why we stayed with them for so long."
"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"Technical support is pretty sharp and very responsive."
"Our primary use case for this product is DLP,"
"The iboss system is highly reliable. The false positive rates are small compared to some other systems we've experienced through other partner agencies who use competing solutions."
"Fortinet FortiGate helps improve my organization since it's quick and easy to install, and we don't have to call support frequently."
"FortiGate Next Generation Firewall has a simple configuration."
"Integrated management is a very valuable feature."
"We like FortiGate's website change feature."
"Customers keep on improving their licenses. The solution remains scalable and flexible. On-premises deployments may have some limitations. However, cloud deployments offer a high degree of flexibility."
"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."
"It can expand easily."
"We use the filtering feature the most. It has filtering and inbuilt securities. We can create customized rules to define which users can access a particular type of site. We can create policies inside the firewall."
"The protection is most valuable."
"The security is excellent."
"Zscaler Internet Access's best feature is the granular policy controls."
"Zscaler Web Security protects our users in remote locations from internet threats - even if they are not connected to our network."
"The most valuable feature for me is the ability to see how my network and traffic looks with modules like analytics and insights."
"The solution is scalable and stable."
"​After a proper implementation, the maintenance is very low.​"
"Zscaler Internet Access protects using data loss prevention. If you have a CASB exposing your cloud out into the network, then Zscaler Internet Access will go ahead and control that unknown cloud application in the CASB, protecting it. There is also data detection with exact data match. This improves the data coming into your cloud so you are protecting it."
 

Cons

"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"The reporting feature needs improvement."
"SSL decryption: We had issues with learners using apps instead of using web browsers. This type of encryption is tough for any appliance in a BYOD environment."
"The area I would like to see improvement in is the ability with in the reporter to navigate directly to the content the user is traversing. It is kind of there, but it's not perfect. Quite frequently, I receive links that lead me to pages with error messages."
"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"The dashboards for local use could be better."
"They should make the product user-friendly and enhance the security features."
"The product has to be upgraded every few weeks."
"The solution is expensive."
"In my case, the 101F is not scalable. I faced problems with scalability related to memory. When we hit 100% memory usage, it stops the internet connection, so we need to control the traffic. We cannot increase the memory."
"Some features of Fortinet FortiGate are actually fee enabled that are inconvenient for deploying in production. Other issues relate to isolation with Cisco products and your server."
"The captive portal could be improved."
"Its reporting can be improved. Sometimes, I don't get proper reports."
"The solution needs to integrate VPN features."
"Do not expect to pay for the service and start using it, like Gmail. Zscaler requires a proper implementation to be done to make it successful."
"There are a few features that are not compatible with the Azure cloud."
"One thing that needs to be improved is their presence in China. I'm not sure if that's a Zscaler thing or if it's a problem with all vendors in this space, but it would be nice to have better coverage in China. This concern is a common one for vendors across the board when dealing with the Chinese market."
"The reporting functionality could be a bit easier to use. There is a reporting function, but it's quite hard to do any good reporting, from a user-management perspective. For example, if a department manager wants to know how his department is using the web, there is a way to get the data, but it's quite cumbersome to get it and show it well. And that's true for comparing between departments."
"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."
"The solution's technical support needs to be improved, especially by offering a better support structure for different geographical areas."
"One thing that they could improve is the ability to import rules from other platforms."
"The solution can be improved by advancing some of the newer technologies such as the DLP feature, and adding email security."
 

Pricing and Cost Advice

"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."
"The overall pricing for iboss is very competitive and transparent."
"It is probably in line with other solutions, but I do not deal with the financial side."
"It is expensive compared to one of its competitors."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"Cost-wise, there is not much difference from Sophos, but feature-wise, we get more features."
"There is a license to use Fortinet FortiGate."
"It is a good product from a price perspective versus functionality."
"The pricing of Fortinet FortiGate is average, not cheap or overly expensive compared to other firewall solutions in the market. It's effective and affordable for customers."
"While Fortinet FortiGate has a higher price point compared to Sophos XG, its user-friendly interface justifies the cost."
"It's very affordable."
"The solution's pricing is competitive."
"Pricing is lower than Cisco."
"Licenses are available on a per-host basis. Some features like sandboxing require an additional fee, but most standard features are included in the license."
"It is a few pounds per user per month."
"The pricing is fair based on its competitive market."
"Our monthly fee is around R3000."
"The solution is a little bit expensive. On a scale of one to five, I would rate it as a three."
"Zscaler is transparent about its pricing model."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."

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.
