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.

Advanced rollback and AI-driven insights have protected endpoints and simplified security operations
We can check multiple types of alerts and triggers, and we can analyze these. There are many types of functions such as Kill, Quarantine, and remediate rollback types of features, which we can use for client safety. The rollback feature is the best feature because it is only used in SentinelOne Singularity Cloud Security. We have used multiple types of EDR, but the rollback feature is unique to SentinelOne Singularity Cloud Security. When many types of attacks happen in an organization, the rollback feature deletes all types of malicious files and other malware-type files and completely cleans your system. This feature is very interesting according to me. SentinelOne Singularity Cloud Security provides many types of features such as Kill and Quarantine, which are very interesting features for security operations. There are deep visibility features, and Purple AI is also one of the best features. It is easy for security operations and incident response. We can check log analysis with the help of deep visibility, and any types of attacks, malware, and phishing attacks are detected by SentinelOne Singularity Cloud Security. Many types of security operations can be tracked and observed with the help of SentinelOne Singularity Cloud Security. Purple AI is one of the interesting features in SentinelOne Singularity Cloud Security. Deep visibility is one of the best features in SentinelOne Singularity Cloud Security. You can find any types of logs and any types of devices through searching portals, similar to Google search. It gives you information regarding this. With deep visibility, you can search for any name. For example, we can search for any name and check what is happening with that person's laptops, what USB is connected or disconnected, and whether the network is connected or not. This is with the help of Purple AI.

Has enabled me to reduce false positives and perform deep credential auditing with seamless integrations
I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature. Regarding integration capabilities, we can integrate Tenable Nessus with SIM tools such as Splunk, IBM QRadar, and Azure Sentinel, as well as with ticketing systems such as ServiceNow, Jira, and Slack. There is no complexity as it is very easy to integrate everything. In terms of the reporting feature, while vulnerability scanning can throw some false positives, Tenable Nessus has very few, achieving a reduction of 75% to 80% false positives with manual analysis needed. We can generate standard Nessus reports that typically include host summaries and vulnerabilities by host and plugin, alongside solutions and remediation recommendations. The main benefits I get from Tenable Nessus are complete asset inventory and comprehensive attack surface management, allowing us to prioritize vulnerabilities based on risk, focusing on true risk and threat path analysis.
