Senior Manager - Pre-Sales at Trillium Information Security Systems
Offers robust compliance features but needs improved automation in remediation
The automation capability remediation needs improvement. The current process requires manually telling IT teams to remediate vulnerabilities, and then they update the status of these vulnerabilities in the platform. This basic feature that Rapid7 calls an automated remediation process is actually manual. We can update the status of vulnerabilities in the Rapid7 InsightVM platform and collectively see how many vulnerabilities we have identified and how many are remediated by our IT team. More automation in the remediation feature is a basic demand from many customers. The remediation part and vulnerability identification of network devices or rigid devices are not currently supported by Rapid7 InsightVM. More integration and automation are the two areas Rapid7 needs to improve in their product.

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.

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.
