Abhinandan Yadav - PeerSpot reviewer
Network Security Engineer at Arrow PC Network Pvt Ltd
Unified security and sd-wan have improved uptime and cut wan costs for multi-site branches
Users report stability issues in certain versions, which requires regular updates. Real-world attacks have also highlighted the need for urgent patching of vulnerabilities.Fortinet FortiGate, while a powerful and feature-rich web firewall, could improve in areas like firmware stability, documentation, and ease of use. The learning curve can be steep for some users. For beginners, support quality can vary, and frequent updates with occasional vulnerabilities call for careful patch management. However, once Fortinet FortiGate is configured, it remains highly reliable and efficient. Customer support needs improvement, as I find it very slow, with reports from other users reflecting that customer support is inadequate.
TarunPanchal - PeerSpot reviewer
IT Manager , SAP HANA Administrator at Tara Paints & Chemicals
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.
Mohan Janarthanan - PeerSpot reviewer
Associate Vice President at Novac Technology Solutions
User access management and threat prevention are enhanced with user-friendly controls
The best features Zscaler Internet Access offers include application control, tenant segregation, and PoP center regions which have low availability zones. The internet access is very successful and bandwidth speed is excellent. It also has application-based control, URL-based control, and SSL inspection capabilities, which are very useful. Additionally, the in-depth CASB segregation is very beneficial to us. One unique feature I found helpful is the tenant level restrictions, which we use to only access our organization's tenant level mail IDs, drives, and specific tenant level access while restricting public access. Zscaler Internet Access has positively impacted our organization as we have noticed substantial outputs and income. It has improved our security environment control and endpoint protection. It prevents numerous web attacks through its AI/ML incorporated capability which identifies malware, threats, and viruses. It has a toggle button to enable features entirely at the tenant level for all users onboarded into Zscaler Internet Access, resulting in much better outcomes.
