MYTH: “We generate an SBOM on every build, so our software is secure.” REALITY: Your build was clean yesterday. A new vulnerability dropped this morning.

When a new critical vulnerability hits the headlines, the first question leadership asks is simple: Are we affected?

In theory, if your Software Bill of Materials (SBOM) is ingested into a centralised platform, it should give you that answer in seconds. In practice, having an ingredient list does not stop food poisoning. Having visibility is only the starting line, managing risk continuously is the actual job.

The Poll: 57% Generate, but Who Actually Monitors?

In a recent poll across three LinkedIn security communities, we asked teams how frequently they generate an SBOM for the software they build:

For teams still establishing their tooling, generating a comprehensive SBOM can be a heavy lift. For the many organisations that already automate this step, however, a deeper industry paradox emerges:  generating the inventory was never the hard part.

The next challenge shifts from “Can you generate an inventory of your assets’ software?” to “What do you do with the inventory the day after you release software?”

The October Release Trap: When Unchanged Code Becomes Vulnerable

Consider a scenario every engineering team faces:

• October: You ship version 1.2 of an application. The build passes with zero vulnerabilities, and the clean SBOM is filed away.
• December: A zero-day advisory drops for a transitive logging library buried inside version 1.2.
• The Reality: Not a single line of your code changed between October and December. Yet version 1.2 is now actively exploitable in production.

This is the post-release blind spot. If your SBOM lives in a shared folder or static compliance portal, it is useless. Re-running a scan on your current main branch only tells you about current code, it tells you nothing about the 6-month-old release still running in customer environments or secondary cloud clusters.

An unchanged release can become vulnerable at any moment. To stay secure, your vulnerability monitoring must be continuous, even when your builds are not.

Moving from Static Visibility to Verified Remediation

Closing the gap between having an SBOM and fixing vulnerabilities requires three operational shifts:

1. Look Beyond the Surface

Checking only your main software packages gives a false sense of security. Most security flaws hide inside the background libraries those packages pull in. Whether a defect is buried 3 or 13 layers deep, your tools still need to catch it.  This is an important part of securing your software supply chain.

2. Focus on Real Risk, Not Generic Ratings

A theoretical warning in a tool you only use for internal testing is rarely as urgent as a moderate issue sitting on a live, public-facing website. Default risk scores don’t know how your software is actually being used. Prioritisation means figuring out if a flaw can truly be exploited in your system.

3. Define Clear Responsibility for Fixes

In many organisations, a developer updates code, closes the tracking task, and moves on. Meanwhile, the older, vulnerable version of the software is still running for active users. Someone needs to be explicitly responsible for confirming that the verified fix actually reaches live systems before calling the job done.

4. Cover Your External Supply Chain

Managing software risk is not only a function of the software that your organisation creates but also a consideration of any third-party applications and vendor software operating in your environment. In today’s world of SBOM management, this means that external SBOMs from vendors must be ingested and monitored as well as your own internal software.

A complete workflow requires four distinct checkpoints:

• Application Owner: Identifies which live deployments run the affected component version.
• Security: Assesses true reachability and exploit conditions.
• Engineering: Builds, tests, and validates the safe upgrade path.
• Fix Owner: Verifies that the patch actually deployed to all live environments before closing the ticket.

Continuous Defense with Meterian Sentinel

Visibility without automation turns your security team into full-time ticket managers. Meterian Sentinel bridges this exact gap. When enabled, Sentinel continuously and automatically checks your previously scanned releases against newly disclosed vulnerabilities daily, without requiring new builds, manual rescans, or developer intervention.

What is more important is that Sentinel is not limited to the software that your development teams write. Meterian can also consume external SBOMs whether they come from third party vendors, partners or existing pipelines.

When an advisory drops, you know immediately which deployments are exposed and what fix to prioritise.

A Quick Test for Your Team

Pick one application your organization shipped 3 to 6 months ago that hasn’t been rebuilt recently:

The Diagnostic Question: Can you identify within 5 minutes which open-source libraries it runs, whether any newly disclosed CVEs affect it, and who is responsible for verifying the patch in production? The Reality Check: If that answer requires manual searches or cross-departmental meetings, your SBOM is an archive, not an active defense.
