Mark Freeborough - PeerSpot reviewer
Client Manager at MLL Telecom Ltd
Network segmentation has strengthened access control and now streamlines automated threat response
The most valuable features in FortiCNAPP include robust network segmentation and restricting access to network assets. It also supports security measures by leveraging security fabrics for better enforcement and policy enforcement. FortiCNAPP integrates with SIEM solutions, and we offer different SIEM options that work with Fortinet and AlienVault, among others, providing multiple scenarios.FortiCNAPP's automated policy recommendations significantly help improve security measures as part of an overall service wrap. When deploying a Fortinet SD-WAN or network, these tools provide greater visibility to vulnerabilities and enhanced security on the network. It functions as a proactive tool, enabling me to identify threats quickly and automate responses.
Chethan Gowda - PeerSpot reviewer
Windows Security Patching Operation III (Cyber Operations) at CBTS
Have maintained accurate vulnerability scans and gained actionable remediation insights across thousands of servers
Tenable Vulnerability Management agents are very lightweight, and the results we get are very accurate. The solutions they provide to us, assuming if one vulnerability exists, there will be a solution. The resolution they give us in wording will be the best solution. The exploit rates and the reports we get provide a lot of information, making it very easy for us to verify.The main benefit of integration with Tenable Vulnerability Management is that there will be no lack of missing vulnerabilities when it comes to the patching environment. That is one of the key aspects of why we have integrated Tenable to our patching tools. It has a vast capacity of pushing the data to our tools due to its capability and compatibility. That is also one of the reasons why we are using Tenable Vulnerability Management.
