We’re now required to provide a Software Bill of Materials (SBOM) for every release, but keeping it updated across 50+ microservices is a nightmare. How are you guys automating the scanning of open-source dependencies and "transitive" vulnerabilities? Is anyone using tools like Snyk or CycloneDX to block builds that contain "unreachable" but vulnerable code paths?

We’ve integrated CycloneDX directly into our GitHub Actions. Every time a PR is merged, it generates a fresh SBOM and compares it against the "Vulnerability Exploitability eXchange" (VEX) data. This is key because it tells us if a vulnerability is actually reachable in our specific code. We used to waste hundreds of hours fixing CVEs that were in unused parts of a library. Now, we only "break the build" if the vulnerability is in a function we actually call. It’s moved our focus from "compliance" to actual "risk reduction," which our devs appreciate.
Deborah, how do you handle the "false positives" from those reachability scans? Sometimes the tool says it's unreachable, but a clever exploit might prove otherwise.
We’ve started using "VEX" documents to communicate to our customers which vulnerabilities are NOT applicable to us. It saves a lot of back-and-forth emails during their security audits.
VEX is a game-changer for transparency. It’s finally moving the conversation from "Do you have bugs?" to "Are these bugs actually a threat to my data?"
Gary, we have a "trust but verify" policy. If the tool flags it as unreachable, it goes to a low-priority queue for a monthly manual review by our security champions. We don't block the release, but we don't ignore it forever either. This balance keeps our velocity high without leaving us completely exposed to "black swan" exploit scenarios that the automated tools might miss.
