Biswajit Jena

Technical Director at Entrust Software Development India

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.

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."

"RedSeal integrates the network and gives us a visual or graphical overview of our network. If an organization is geographically dispersed, for instance, with one office in Canada and one office in the Philippines, the whole network, including all devices, is integrated into RedSeal, and you can see from where the traffic is going in and out."

"Overall, I am very happy with the way the product is working."

"This is the only solution in the world that gives you a digital resilience score."

"If you want to understand your network environment as it relates to configuration issues, host/node vulnerabilities and firewall configurations, then I highly recommend that RedSeal be considered."

Cons

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

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

"One of the areas of concern is the GUI. It is important to our customers that the GUI looks beautiful."

"There is room for improvement in integrating the OT security part and the private 5G security part in RedSeal."

"Although we are talking about a very robust platform, I would like to see the Windows compatible VM version come back."

"There is room for improvement regarding customization and automation of reports."

"One of the areas of concern is the GUI. It is important to our customers that the GUI looks beautiful. It's a Java Client, so you have a Java dependency."

"Initially their level one support was very frustrating to work with."

"The dashboard should be improved to make correlating data easier to do."

"The network mapping/visualization could be improved significantly."
