Cyber Security Architect at a retailer with 10,001+ employees
Unified vulnerability data has transformed risk prioritization and optimized remediation effort
The best features that Nucleus Security offers in my experience are the unified integrations with all of the different vulnerability management platforms. It is helping quite a lot to unify all of that. It also offers good prioritization based on the EPSS or the CVSS score, as well as different other factors including Mandiant threat intelligence and similar aspects. It helps bring it all into one big picture instead of different silos of vulnerabilities. The integrations make my job easier because I can connect my other tools, which is the most important part of this tool to bring in all the vulnerabilities from the different other tools. The prioritization changed it from chasing vulnerabilities or pushing colleagues to patch vulnerabilities to providing colleagues with their vulnerabilities and requesting remediation and patching. Nucleus Security positively impacts my organization by bringing awareness to vulnerability management since we can actually determine how many vulnerabilities we have and how critical the risk is, or we can quantify the risk overall for the company.

It checks for and reports vulnerabilities on all SAP systems at the OS, DB and SAP levels.
I really love how Onapsis X1 is able to check SAP for threats; the reporting was something I felt could be improved. It could be a little easier to use and to publish for consumption with a larger audience. Currently, it takes some background jobs and additional work to get them published. It was difficult to get interactive reports to the different levels of the business. I would have to download them and send them out, or save them on my SharePoint site and send out a weekly link. In the version of the product I was usingת I had to log into the X1 system directly to get to the reports. Reporting would be used by several different areas of the organizationת many of whom would be at the director and executive levels. It would not make sense to have them log directly into the tool to look at these reports. Add to this that there was only one ID that could be used to log in and view the reports. To solve this problemת I had to run all of the different reports; executive summary down to detailed analysis and then export them out to my security team SharePoint site. To automate this processת a batch script was created to run after the X1 analyzed the systems. The script would pull the reports and place them in the SharePoint site automatically, but it was a bit of a hassle to get set up.
