Risk-based visibility has transformed how I prioritize cloud vulnerabilities and protect key assets
The best features Qualys TotalCloud offers are cloud asset visibility, vulnerability assessment, and risk prioritization. This risk-based prioritization helped me quickly identify high-risk vulnerabilities and focus on remediation instead of going through every finding. TrueRisk-based prioritization is useful for understanding which vulnerabilities need attention first. It improved our workflow mainly by giving us a single view of cloud assets and their risk, so we could focus on the higher priority vulnerabilities instead of reviewing every finding manually. This helped us prioritize remediations more efficiently and reduce the time spent on vulnerability assessment and follow-up. Qualys TotalCloud helped us identify exposures that might otherwise have been missed, especially across cloud assets, vulnerabilities, and identities. With the SaaS configuration, the unified inventory and risk view made it easier to connect vulnerabilities with asset criticality, exposure, and access permissions, allowing us to investigate high-risk exposures first and address them before they could become bigger security issues.

Monitoring has improved data loss detection and now spots abnormal internal file transfers quickly
In my understanding, the best feature Darktrace offers is the identification of copying files, which acts as a DLP, and it is a main concern for companies because users sometimes copy data outside without knowing, especially those without a technical background. When I mention the DLP-like feature and file copying detection, the alerts have been very timely, as we get an alert within a couple of minutes, which is excellent. Even if some developers are working after hours and copying files, our SOC team detects this, and most of the time they call us so we can identify the users. The alerts are quite accurate and proactive.

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.
