TL;DR: Secure software development has to address intake, build, and runtime together, Rapidsort argues, citing 85% open-source software adoption, 10 hours from disclosure to active exploit, and more than 235,000 known-fix CVEs identified from 2016 to 2025. The governance lesson is that vulnerability reduction, SBOM discipline, and runtime visibility now need to be treated as a continuous control system, not a late-stage patching exercise.
Editorial analysis by NHI Mgmt Group, based on content published by Rapidsort: “Secure Software Development Lifecycle”.
By the numbers:
- 85% of enterprise software is open source.
- It can take 10 hours from vulnerability disclosure to active exploit.
Key questions
Q: What breaks when secure SDLC hardening stops at the build stage?
A: The main failure is that teams mistake a hardened artifact for a hardened service.
A: Regular scanning only sees what is already in the artifact.
Q: How do security teams know if runtime protection is actually working?
A: Look for evidence that suspicious behaviour is detected fast enough to contain it before the session or workload expands the blast radius.
Practitioner guidance
- Adopt approved hardened base images Standardise on curated container images that remove unnecessary packages and known vulnerable components before new services are built.
- Generate SBOMs in the CI/CD pipeline Require build-stage software bills of materials so component inventory, applicability analysis, and remediation priorities are available before release.
- Prioritise exploitable findings over raw CVE volume Use exploit-aware scoring to separate theoretically present vulnerabilities from issues that are reachable in the current build context.
Bottom line: Secure SDLC hardening only works when teams govern the full path from intake to runtime, not just the release gate.

Secure SDLC hardening has become a governance problem, not just a build problem. The article shows that risk now spans intake, build, and runtime, which means the control objective is lifecycle integrity rather than point-in-time scanning. That is a familiar pattern in identity security: if the trusted state is only checked once, drift becomes the real attack surface. Practitioners should treat software supply chain evidence as continuously governed state.
A question worth separating out:
Q: When should organisations prioritise build hardening over later remediation?
A: They should prioritise it as soon as the same component or image is reused across multiple applications or environments. Early hardening prevents the same vulnerable artefact from propagating downstream, which is far cheaper than fixing the issue after release. The right sequence is to reduce inherited risk before it becomes repeat exposure.
