Featured Reviews

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.

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

"The next-generation firewall is great."

"The email protection and VPN features are the most valuable."

"We can detect any attack of viruses or malware at the first point of contact."

"Fortinet FortiGate is easy to use. Anyone can easily maintain it."

"There’s something magical about the way the flavors blend together, creating a dish that is both comforting and exciting."

"The best features of Fortinet FortiGate include everything about networking, such as routing and VPNs."

"Fortinet FortiGate offers several valuable features, particularly as an interface-based solution. Its design makes it easy to understand both incoming and outgoing network traffic through its interface."

"Security, SD-WAN, and Streetscape are valuable features."

More Fortinet FortiGate pros

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

"The most valuable feature is the authentication feature."

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

"Cisco Secure Access has protected our company against threats such as phishing or ransomware, as we have seen it successfully address various cybersecurity vulnerabilities."

"I would rate the scalability a ten out of ten."

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

"The firewall section for IDP is the most used for remote sites. It fits better with all the data we're collecting from the protection site and the information that we provide to another customer."

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

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

"For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial."

"They could improve the response time and quality of support."

"Not all features are available in the web UI. Features such as enabling multiple MPLS circuits can only be accomplished through the command line, so these need to be made available in the web UI."

"In the past six months, they took quite a long time to respond to the support tickets. I don't know if they are overwhelmed with too much activity, but for the last six months, the support has not been very good."

"Their software support needs improvement. I would prefer to have better support for bug fixes. Sometimes, we open a ticket, and it is very difficult to get a solution. Specifically, we are not at all happy with their support for load balancing."

"With the reports, you can see it, and you can get good feelings so upper management can go, "Oh, wow. That looks pretty." However, it's very basic."

"Its customer service could be better."

"Technical support for this solution can be improved."

More Fortinet FortiGate cons

"There is a need for improved global coverage since the service relies on the cloud provider's data centers."

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

"The way that we're using Cisco Secure Access today, it doesn't scale with the growing needs of our organization, however, if we leveraged more of the cloud services, it would fit better."

"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 licensing is confusing."

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

"From a licensing perspective, Cisco can improve."

"It is expensive."

More Cisco Secure Access cons

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

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

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

Pricing and Cost Advice

"For medium and enterprise organizations, FortiGate is more affordable."

"Their licensing costs are annual. The UTM feature license along with their support is called FortiCare. We include that as a part of the annual maintenance cost. Palo Alto or Juniper also have an annual subscription charge for UTM. Price, of course, can always be more competitive, but it is not the most expensive product. The price-performance ratio is quite high for FortiGate."

"Fortinet FortiGate as a less expensive solution than Palo Alto."

"Its pricing is good. The advantages of Fortinet FortiGate over its competitors include good pricing and meeting our requirements at a lower cost."

"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 price is high compared to some of the other solutions."

"Its price is normal. If I compare it with other vendors, such as Palo Alto, it's normal. Palo Alto is expensive."

"Its price is reasonable. They have a clear pricing policy. It is not complicated by the number of VPN users at a time. We know what the price is. The yearly subscription for the security license is rather high, but it is all included for whatever number of users you have and the kind of functions you need."

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."

"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."

"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."
