Security scanning has protected our pipelines but currently needs clearer dashboards and controls
We used additional third-party solutions, but we replaced them with GitHub Advanced Security, even though I do not have a very good opinion about GitHub Advanced Security. Even though it is an inline product, I'm not seeing user-friendly things in GitHub Advanced Security. Dependent bots and the secret detection are good compared to others. However, code scanning is not finding very good results based on pipeline where it will scan and do code scanning. While build, before building and deploying the code, we want to block or do an advanced model, but it is not supporting. During deployment, code scanning is not good. It is a little complicated. It is not a straightforward method we can complete. We need expertise to get the full benefit, and troubleshooting sometimes requires going through that. The security overview dashboard is not really clear. It's not showing centralized information; each repo is showing, but if you compare it with competitors, it is not that great. Mainly in the centralized dashboard, enterprise level needs to improve. A centralized way where we can get that overall view is needed, and we want that code scanning and blocking deployments based on security. There are AI improvements, but however, it is not so easy to configure. It is multiple windows we need to go through and make changes or configure that. A few things we need to enable going into settings, and a few things we can find out in security. One product where security means the security dashboard should cover everything, but it is going here and there in many places.

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

"It ensures user passwords or sensitive information are not accidentally exposed in code or reports."
"Dependency scanning is a valuable feature."
"GitHub Advanced Security uses artificial intelligence in the backend, specifically CodeQL, to analyze code and provide fewer but more reliable findings, so there are less false positives."
"The most valuable is the developer experience and the extensibility of the overall ecosystem."
"The initial setup was straightforward and completed in a matter of minutes."
"The best features of GitHub Advanced Security are its flexibility and the multiple options it has compared to other tools."
"GitHub Advanced Security is ten out of ten scalable."
"The product's most valuable features are security scan, dependency scan, and cost-effectiveness."
"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."
 

Cons

"GitHub Advanced Security should look into API security issues, which they currently do not. Additionally, open-source security vulnerabilities are not getting updated in a timely manner."
"A more refined approach, categorizing and emphasizing specific vulnerabilities, would be beneficial."
"The deployment part of the product is an area of concern that needs to be made easier from an improvement perspective."
"For GitHub Advanced Security, I would like to see more support for various programming languages."
"There could be DST features included in the product."
"We used additional third-party solutions, but we replaced them with GitHub Advanced Security, even though I do not have a very good opinion about GitHub Advanced Security."
"Maybe make it compatible with more programming languages. Have a customized ruleset where the end-user can create their own rules for scanning."
"There could be a centralized dashboard to view reports of all the projects on one platform."
"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."
 

Pricing and Cost Advice

"The solution is expensive."
"The current licensing model, which relies on active commitments, poses challenges, particularly in predicting and managing growth."
