Vasu Gala

Manager, Information Technology Operation/Presales at TechMonarch

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.

Vasil Blagov

Manager, Network at Duracell International, Inc.

Easy management and security ensure reliable 24/7 connectivity

Zero Trust Network Access has helped my organization in securing standard applications because it's mandated to have it. It provides peace of mind knowing that we have that deployed in our network. Cisco Secure Access's ability to provide secure access via standard HTTP2, and optionally, QUIC protocol is good. It complies with the new standards. The impact of Cisco Secure Access on protecting my organization from phishing and ransomware threats has been good so far. We've been doing well with no threats.

Alexander Azikov

It Manager at Diamond Braces

A robust appliance that is reasonably priced and straightforward to set up

Although manageable, the user interface is a little bit slow and could be improved. There are two user interface options available, namely the basic and the advanced. The basic UI is not very good and doesn't have a lot of features, although it is fast. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists. At one of our sites, the CPU utilization was very high, and for no reason. Technical support needs to be more responsive to requests.

Quotes from Members

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

Pros

"It's very fast and easy to configure."

"Overall, the pricing of the solution is very good. The product offers good value."

"The most valuable feature is the VDOM, which allows the customer to have multiple firewalls in a single campus."

"The most valuable features of Fortinet FortiGate are the ease of use and there are several operating systems that can include the hardware capacities. In the newer releases, the resources were more useful because they were included in the operating system."

"The web filtering facility and application control are the most valuable features from the point of view of our clients. The VPN feature is also quite popular amongst our clients. Two-factor authentication is one of the good features in Fortinet. These features are important for the current scenario of security. Security has become a necessity nowadays. With cyber-attacks becoming more common, protecting an organization's data is one of the major tasks. It is also very stable and scalable, and it is very straightforward to configure. Their technical support is also good."

"It's very similar to a Cisco firewall, yet less expensive."

"The interface is very good."

"The most useful feature of FortiGate IPS for me is Application Control."

More Fortinet FortiGate pros

"I rate the stability of Cisco Secure Access as ten out of ten."

"I find the posture checking feature of Cisco Secure Access the most valuable."

"The impact Cisco Secure Access has on protecting my company from threats such as phishing and ransomware is significant."

"It works well. It hasn't broken. While I don't know enough about all the features yet, it hasn't caused us any problems."

"The features of Cisco Secure Access that I most prefer are easy management or manageability, and overall security."

"The feature of Cisco Secure Access I appreciate the most is the DNS functionality."

"Cisco Secure Access has benefited my organization by allowing people to connect 24/7, ensuring reliability."

"They've protected us from threats like phishing and ransomware."

More Cisco Secure Access pros

"The solution can scale well."

"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."

"This is a capable appliance and the standard features work well for us."

Cons

"I use the FortiGate 60D model and realized the 300Mbps bandwidth limitation. Because it is a product that offers many services, I think it could have greater bandwidth capacity."

"We also have FortiAnalyzer deployed here, so we want to enable the soft functionality of FortiGate and built-in compression for a firewall VPN use case. We want the ability to deploy a gateway for HTTPS enabled on this firewall. It is currently only for use in our headquarters."

"The support costs and licensing are sometimes so expensive."

"In the next release, maybe the documentation on how to use this solution could be improved."

"The command line is complicated, and the interface could be better."

"The solution has many heightened points which we cannot get to without working on CLI."

"FortiGate Next Generation Firewall could be made a little less expensive."

"Some of the features in the graphical user interface do not work, which requires that we used the command-line-interface."

More Fortinet FortiGate cons

"The worst part was the migration from Umbrella to Cisco Secure Access; we experienced some difficulties during that process."

"Cisco Secure Access can be improved with more integration; the more integrations, the better. There are always third-party products that you might have, such as Carbon Black."

"The worst part was the migration from Umbrella to Cisco Secure Access; we experienced some difficulties during that process."

"It is confusing. When you look at the prices, you have different licensing and years of licensing that you have to purchase. Additionally, it's unclear what service you get from those licenses regarding end-user support. We have a representative who has to walk me through it every time."

"The main issue with pricing is that it is higher compared to other competitors, making it challenging to work with customers unless they specifically request Cisco."

"Throughout my experience with Cisco Secure Access, I have had some stability and reliability issues, including lagging when accessing the portal."

"I received support from the team for Cisco Secure Access related to web services. There were occasional delays of up to two working days."

"From a licensing perspective, Cisco can improve."

More Cisco Secure Access cons

"Although manageable, the user interface is a little bit slow and could be improved."

"Sometimes it reboots when you least expect it, and that's the main issue."

"The product has some scalability and data management issues where improvements are required."

Pricing and Cost Advice

"Fortinet FortiGate's price can be reduced."

"Fortinet costs are 25% lower than the high-cost provider. There is an equipment cost and a recurring monthly cost for licenses and technical support."

"The solution is more expensive than Sophos. It could be cheaper. The licensing is on a yearly basis. We have had it for about three years. We must only pay extra for the license, additional requirements, and the hardware box."

"The price of Fortinet FortiGate is reasonable."

"I think that the pricing is fair."

"My experience with the pricing, setup cost, and licensing for Fortinet FortiGate is quite good. I don't have a public site, such as in Azure, where I can see the pricing. I always have to go through the distributor, and that could take some time to get the real price for each appliance."

"The pricing is fair."

"I would rate the pricing a five out of ten"

More Fortinet FortiGate pricing and cost advice

"The pricing, setup costs, and licensing for Cisco Secure Access have been very competitive compared to other platforms. I believe that if Cisco continues to improve costs or offers something similar to a Cisco credit, it would attract more customers."

"For what you get, it's a fair price in comparison to other products."

"This gateway is pretty cheap."

"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
