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.

Unified security policies have protected our hybrid network with deep, user-based controls
The main limitations of Check Point Cloud Firewall (formerly CloudGuard Network Security) are not in Check Point itself but in the cloud platforms on which it is deployed. Because not all clouds have L2 infrastructure, you cannot build a unified clustering system everywhere. As a result, the problem usually is not with Check Point, but with the cloud. The main problem with Check Point Cloud Firewall (formerly CloudGuard Network Security) is that it uses a separate thick client instead of a browser. A browser-based SmartConsole exists, but it still has a number of limitations, while the thick client, the so-called SmartConsole, often works unstably, freezes, and has to be restarted. I do not recommend using Check Point Cloud Firewall (formerly CloudGuard Network Security) as a VPN hub for site-to-site VPN because it is inconvenient to monitor the state of its tunnels, especially visually. It does not have a convenient snap-in and everything can be checked only via the console, which is very inconvenient. Check Point is not the most universal solution as a device that provides routing and administration capabilities in addition to security. It is an excellent firewall, but it has a number of limitations in terms of routing and in creating VPN sessions, especially in terms of displaying their states.

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.
