Featured Reviews

Alice Walter - PeerSpot reviewer
Team Lead at Target
Cloud monitoring has reduced threats and has improved response times and team productivity
Alert Logic MDR's best features are the cloud-managed service, the cost benefit, and 24/7 monitoring. The alert system improved from potentially 24 hours to one hour response time. The benefit of not having to write custom queries has been significant.The features are very lightweight, with small installations that leave almost no footprint on systems. System resource utilization is minimal. Alert Logic MDR has positively impacted my organization through its decentralized pricing approach, which has protected against several viruses. Any virus stopped represents money saved. There is low impact on users, so they do not experience slowness on their computers when scanning. Alert Logic MDR has improved security in my organization from 50 to 65%.
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.
