Trust the ground the app runs on.
An application is only as trustworthy as its dependencies and its build. B5 Secure treats the software supply chain as part of the security perimeter: dependencies pinned and hashed, build artifacts signed, SBOMs generated, and provenance attested to SLSA Level 3 — so a poisoned package or tampered build is caught, not shipped.
The challenge
Most breaches now arrive through the supply chain — a compromised dependency, a tampered build step, an unsigned artifact. Without provenance and an SBOM, you can’t even answer ‘are we affected?’ when the next advisory lands.
The Never Trust answer
The secure SDLC is aligned to NIST SSDF: every change is scanned, every dependency is pinned and verified, every artifact is signed, and build provenance is attested — so the ground the app runs on is trustworthy too.
Four controls for the build pipeline
Pinned & hashed dependencies
Dependencies are pinned and hash-verified; audited packages are preferred and inbound/outbound build access is locked down.
Signed artifacts & SBOM
Build artifacts are cryptographically signed and a Software Bill of Materials is generated for every release.
SLSA Level 3 provenance
Hardened, isolated build pipelines produce attested provenance, so a tampered build is detectable.
Continuous scanning
SAST, DAST, dependency, secret, container, and IaC scanning run in CI on every change.
Secure the build, not just the app.
