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.

Comprehensive Security Features and High Ease of Setup Elevate User Experience
The best features for KerioControl are its proprietary VPN protocol, which does not connect easily with other firewalls unless you enable IPsec. It will only connect to KerioControl. KerioControl is very valuable for business. Key points where KerioControl is valuable include its own anti-spam, intrusion prevention, and antivirus, which is included in the yearly subscription renewals. The VPN capabilities are helpful in managing my remote or distributed workforce, as we create documents and set up a location for clients to download. Clients can download KerioControl's VPN client online, and they just have to log in from the VPN client, which connects easily. I assess the firewall function in filtering both incoming and outgoing network traffic with KerioControl as excellent. Everything is logged, and any intrusion, antivirus, virus, or anything foreign to the system trying to hack in gets logged, and we can easily block those IPs.
TarunPanchal - PeerSpot reviewer

Decades of expertise lead to seamless installations and robust security
I typically use the Sophos XG Firewall to enhance my cybersecurity by using all layers. The intrusion prevention system impacts my security posture effectively, as we have not faced any ransomware or cyber threats. I have more than 800 servers live from Sophos. The synchronized security feature has proven to be very beneficial, and I have not encountered any issues. Sophos XG Firewall has contributed to reducing overall costs because it helps save money. We purchased endpoint security for the first time last year, and even without endpoint security, it provides comprehensive security. Sophos XG uses AI effectively to enhance threat detection and response, securing from AI at the packet level.
