Setup Cost

Fortinet FortiGate is cost-effective and flexible compared to competitors, but may be expensive for small businesses.

Cisco Secure Access pricing is confusing and costly, with licensing complexities affecting competitiveness despite some discounts and positive experiences.

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.

Secure access has unified zero trust and web protection while AI assistance automates tasks

Network Operations Engineer at Redex IT Limited

From a feature perspective, I have not experienced any issues, drawbacks, or shortcomings. However, the cost of Cisco's products and licensing is high. My clients usually prefer cheaper options if possible. Mid-size or smaller businesses typically cannot afford Cisco Secure Access. Additionally, there is a steep learning curve, as it is very intensive. Someone with significant knowledge can work on it, but a new professional would have to spend considerable time to get accustomed to it. It is hard to find engineers who can work on it. Overall, we get what we pay for, as it is a pretty good feature and service. The pricing of Cisco's products and licensing is higher than competitors. If they could be more reasonable, that would help. The support offered for two years also has higher costs. Overall, the client's IT budget gets affected. It was challenging to learn because, as mentioned, it has a significant learning curve and requires considerable training to become proficient.

Has provided strong traffic visibility and efficient policy management for advanced network environments

Sr. Cloud Security Architect at a tech services company with 11-50 employees

Palo Alto Networks K2-Series could be improved, though I don't think of much. I'm unsure how widespread the adoption for K2-Series alone is. Looking at the base Palo Alto capabilities, they are going in the right direction. K2 specifically about its efficacy with all these 5G protocols, the GPRS tunneling protocol performed without many hiccups during testing. With AI, if there is a Precision AI bundle that you're planning on exploring, then that definitely needs a significant uplift because currently it doesn't work for all the known models. There are many false positives that need to be addressed. While it's still ahead of its competitors, on the AI security side, there is quite a room for improvement.
