Unified risk scoring has improved our cloud visibility and simplifies remediation priorities
Qualys TotalCloud provides unified vulnerability and threat assessment across both IAS and SaaS. This solution provides a single prioritized view of risk, which helps reduce the work I would have to do. We are no longer based on CVSS; we are based on Qualys risk scoring, which is based on CVSS plus internal findings made by Qualys, and then assigns its own score. The TruRisk insight feature has found a small number of assets with high vulnerability scores, though I am cautious since some information is classified. Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution.

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%.

Centralized analytics have strengthened patch visibility and support efficient regulatory reporting
From my experience, I assess the product's analytics capabilities as successful. It helped us significantly with patching and managing the risk of the patching process across all our environments, including network devices with Windows and Unix systems. The product covered several environments and gave us exactly what we needed in our environment. Tenable Security Center's centralized platform helped with risk assessment and management across our IT environments. It covered the patching process, and we previously faced many issues regarding how to patch different environments, how to monitor the patching process, and whether it was successful or not. We obtained good reports showing when patches were closed and the details of each patch, including who executed it and everything related to the patching process until it was closed. This gave us good details about the process which helped us significantly in our reporting and even in audits, whether internal or external. We learned how to close audit issues safely and successfully. We used the dashboards for real-time threat insights and extracted several dashboards from Tenable Security Center. We use these dashboards in our cybersecurity dashboard and committees that we have. These dashboards are part of our committees, especially the cybersecurity committee and other committees that we attend.
