Featured Reviews

Vasu Gala - PeerSpot reviewer
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.
Chinedu Onwurah - PeerSpot reviewer
Global Juniper Presales Engineer at Westcon-Comstor
Robust security measures and cost-effectiveness meet diverse industry needs
The biggest benefit of Juniper SRX Series Firewall overall is that it is rugged and cost-effective, offering basic firewall features and additional licensed features as needed. The main challenge I see as a distributor is Juniper's rating in the Gartner report, where Juniper is not a leader in enterprise security, which often influences customer conversations. Most customers want to check the Gartner report before they engage, making it challenging to sell Juniper security. With my extensive experience with the Juniper SRX Series Firewall, the robustness of the SD-Cloud or Security Director interface and overall functionality needs to be improved to compete with leading firewall solutions.
Reviewer921606 - PeerSpot reviewer
Sr. Cloud Security Architect at a tech services company with 11-50 employees
Has provided strong traffic visibility and efficient policy management for advanced network environments
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.
