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%.
OB
Microsoft Solutions Manager at Self-Employed
Ensures strong threat and vulnerability management with continuous risk assessment
The major priority is identity, which is crucial; we have lots of companies in manufacturing, energy, or various sectors, and it varies from one to another. I assess Microsoft Defender Vulnerability Management as very effective in continuously assessing vulnerabilities without requiring scans. We use automatic investigation and remediation features, safe attachments, safe links, and real-time reports, which are also very effective. For Active Directory, Defender has threat intelligence, and we are using that. The risk-based prioritization within Vulnerability Management affects my ability to manage vulnerabilities, particularly in relation to the Zero Trust Model utilized by our customers. The end-users often do as they please in their systems.
