Centralized security testing has improved vulnerability remediation and compliance reporting

I recommend more enhancements focusing on penetration testing for both SSL over HTTP and non-SSL over HTTP, specifically targeting the RCP Rich Client Platform and Equinox frameworks that allow on-premises desktop applications to be tested simultaneously. I believe those would significantly improve the tool in the future. I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities. Once we build this installer—rather than just working on the codebase—sometimes, we face gaps considering the build parameters and conversions to the installer. Identifying those gaps is an area that could use improvement after the installer or desktop application testing, which would be beneficial. That is the only reason; otherwise, I could easily rate it a ten out of ten given its smooth operational process.

Extensive exploit database and seamless integration enhance penetration testing capabilities

The automated approach in the audits or in the hacking testing with Rapid7 Metasploit could be improved because even the same attack you provide today will go in different ways another day. I prefer when the auditor or pen-tester provides the attack in a non-automated mode. For some, it might be a valuable option, but I'm not sure it's valuable for us, as after the attack has been provided, we should release a report detailing how it transpired and what the customer should improve to block this way of attack. If the attack was provided in an automated mode, you cannot receive sufficient information that helps with this final report for the customer. While you can check the vulnerability, and the system will tell you there is no vulnerability, usually, a human can change one, two, or three parameters and using the same technique and the same scripts can break the system. Rapid7 Metasploit could be improved in areas concerning the experience with finding particular scripts pre-installed in the solution. Customers, administrators, and pen-testers spend considerable time trying to locate the specific component they need by the name of the technique or the name of the attack, so any improvements in making it easier to find those predefined components by name or timeframe would be beneficial. Search filters could be a correct improvement.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"We have seen clear compliance and risk control outcomes more than other operational metrics, including fewer process gaps during documentation and safety checks, strong consistency in following protocols for handling, traceability, and staff awareness, better audit readiness, a lower chance of procedure errors, and faster escalation when something appears out of standard, which is very important for us in the healthcare sector."

"I think the best features that Nucleus Security offers are purely the faster remediation to dev tools, which is crucial for managing, prioritizing, and fixing vulnerabilities while helping operational pipelines run these vulnerability management tools."

"All of the features are great."

"I use Rapid7 Metasploit for payload generation and Post-Exploitation."

"Stability-wise, I rate the solution a nine out of ten...Scalability-wise, I rate the solution a nine out of ten."

"It contains almost all the available exploits and payloads."

"Metasploit is the most favored toolkit for network security professionals and penetration testers."

"It's not possible to do penetration testing without being very proficient in Metasploit."

"For a free product, the capabilities are absolutely astonishing."

"It is easy to use, a useful product, and it has a very long list of available payloads."

Cons

"I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities."

"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."

"The initial setup was a bit "tweaky" for the open-source version."

"Better automation capabilities would be an improvement."

"Exploit updates are slow after security patches to a certain OS."

"The reporting feature needs improvement. The time taken to fetch reports based on the number of events can be extensive, unlike Tenable, which is more user-friendly and faster."

"If your company's patch is not up to date, but you have other detection or defense solutions such as endpoint detection and response and antivirus software, the product exploit may not work effectively. This is because its exploit database update process is slow and not real-time. For zero-day vulnerabilities or new security threats, relying on Rapid7 Metasploit alone may not be effective."

"Rapid7 Metasploit can add a GUI feature because it is only available online."

"The open-source version has reporting limitations. You need to develop these capabilities yourself. Built-in reporting is an excellent feature for penetration testing, but it isn't a must-have. The solution could also cover more vulnerabilities. Metasploit has around 10,000 exploits in its library, but more is always better."

"The solution is not very scalable, it does not provide any automation to be able to scale it."
