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.

InsightVM - better functions on granting users different access to different asset groups.  It fits better for our company and is slightly cheaper.

You have full visibility across cloud, network, virtual, and containerized infrastructures with Rapid7 Insight VM. You can easily prioritize vulnerabilities using attacker analytics. Overall, Rapid7 Insight VM is easy to understand, use, and deploy. This solution supplies many different types of valuable reporting and rarely reports false positives. Rapid7 can easily detect new devices and scan endpoints quickly for vulnerabilities, misconfigurations, or missing patches. Rapid7 Insight VM will identify the risk and suggest how to resolve the problem. We would like to see the reporting improved to offer some of the options other solutions provide. Rapid7 Insight VM can be a very expensive solution - it is really only for larger enterprise accounts. Integration with other solutions would make Rapid7 Insight VM more desirable. It’s easy to combine local testing with network-based testing using Tenable Nessus, which can easily find vulnerabilities across different platforms and operating systems. Tenable Nessus will identify what nodes you have in place, then provide you with a report identifying each vulnerability found by node. It works quickly and stealthily, and offers clear-cut reporting and the ability to scan for specific vulnerabilities. We would like to see the reporting process with Tenable Nessus improved. Instead of only PDF reports, one option might be to track with an Excel-based structure to better track vulnerabilities and remediation efforts and build reports from there. An option to use the same license for the cloud and on-premises at the same time would be very useful. Conclusion We felt that Tenable Nessus provided better reporting of vulnerabilities per device in a clearer, easier to understand manner. It is a very easy solution to use and makes accountability for tracing and reporting vulnerabilities easy. The flexible scanning options offered by Tenable Nessus are what we found most advantageous.
