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.

User has benefited from stable performance and effective completion of security tasks

I use it mostly for VPN and for some firewall solutions When considering my main use case with VPN, I can say that I got the Zyxel Unified Security Gateway, and it works fine. However, we are thinking about using a different solution based on open source because Zyxel Unified Security Gateway…

Quotes from Members

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

Pros

"Provides good firewall security and has great VPN features."

"I like the solution's stability."

"It is simple to manage, and there are a lot of functionalities in the same box."

"The FortiGate controls the user's activities and maximizes my bandwidth use overall."

"Its user interface is good, and it is always working fine."

"You can purchase switches and you don't need to do anything with them. You just put in the firewall and the switches get all the policies and rules that you already have in the firewall. With Fortinet, you just connect the FortiSwitch to the Fortinet and that's it."

"One of the best features of Fortinet FortiGate is that it's a very powerful equipment that gives many security features in a single box with good performance, and the user interface is friendly to use and configure."

"The SD-WAN function is very developed. It has SD-WAN functionality with security features in one device. We can manage from one single console SD-WAN and the security policy."

More Fortinet FortiGate pros

"I find the zero trust approach helpful and beneficial in securing standard applications, which means you are accessing the applications directly instead of giving privilege to access the network itself."

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

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

"It's pretty streamlined. Everything you need to find is in the GUI interface, and if you have any trouble, it's easy to navigate and get around."

"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 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."

"Any tool that provides telemetry through logging is a particularly good fit for us because we have to really automate our monitoring."

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

More Cisco Secure Access pros

"The Zyxel Unified Security Gateway solution is stable and does its job effectively."

"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."

"The solution can scale well."

Cons

"I would rate the technical support of Fortinet FortiGate as a five because it is not as strong as Cisco. Additionally, the turnaround time is very high compared to Cisco."

"I would like to have SD-WAN as a part of the Next Generation Firewall. It would enhance high availability."

"There should be some open-source training or free training for decision makers, or some webinars should be available."

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

"During a recent upgrade from old devices to the latest ones, corporate IT faced challenges as there was no straightforward migration process, requiring many manual steps."

"The solution can have more features in a single box that can be multi-applied to integrate everything."

"The SD-WAN functionality is a bit overly complicated and not fully documented."

"It is stable, but its stability can be improved."

More Fortinet FortiGate cons

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

"Cisco is not well accepted in the market since they are somewhat behind their competitors."

"TAC engineers just exit the call once their shift timing ends."

"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."

"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."

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

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

More Cisco Secure Access cons

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

"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."

Pricing and Cost Advice

"Fortinet is the least expensive solution."

"They are very competitive, but we like to have the factory warranty taken care of."

"I would rate the pricing a six out of ten, where one is cheap and ten is expensive."

"The Indian market is different than the European and American markets. When you compare they need to be a bit more aggressive on pricing."

"The value is the capability of having multiple services with one unique license, not having the limitation per user licensing schema, like other vendors."

"If you purchase a one-year subscription with the hardware and then you want to renew for the second year, it is very costly."

"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."

"The tool's pricing is neither cheap nor expensive. Overall, I find it to be competitive in the market."

More Fortinet FortiGate pricing and cost advice

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

"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."

"This gateway is pretty cheap."

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