Secure Development Lifecycle

Trust Center · Secure Development

A secure development lifecycle aligned to NIST SSDF.

B5 Secure’s development practices align to the NIST Secure Software Development Framework (SP 800-218) — the practices a regulated reviewer expects to see in the team that builds the code you compile into financial-grade systems.

Why this matters

You are not just trusting the artifact — you are trusting how it was built.

For embedded security software, the development lifecycle is part of the attack surface. A reviewer needs evidence that security is designed in, that changes are reviewed, that vulnerabilities are caught before release, and that the response process is real. B5 aligns to the NIST SSDF practice groups so that evidence maps to a framework reviewers already know.

The B5 approach

SSDF practice groups, applied.

Organized to the four SSDF practice groups — Prepare the Organization, Protect the Software, Produce Well-Secured Software, and Respond to Vulnerabilities.

Prepare the organization (PO)

Defined security requirements, roles, and toolchains, with security criteria built into the development process from the start.

Protect the software (PS)

Integrity protection for code and releases — signed packages, provenance, and controlled, least-privilege access to the pipeline.

Produce well-secured software (PW)

Threat modeling, secure design review, code review on every change, and automated security testing as release gates.

Respond to vulnerabilities (RV)

A coordinated disclosure channel, triage, and a documented patch/support SLA — vulnerabilities are found, fixed, and communicated.

Designed-in, not bolted-on

B5’s own product embodies Never Trust; the SDLC applies the same posture to how the product itself is built.

Evidence a reviewer can map

Practices map to SSDF identifiers, so your assessment slots into a framework your team already uses.

Where it earns its place

How reviewers use this.

AppSec

Framework-mapped evidence

SSDF alignment lets your assessor evaluate B5’s SDLC against a known standard, not a bespoke narrative.

Procurement

Faster diligence

A recognized framework shortens the security-development portion of vendor review.

Audit

Supply-chain continuity

SSDF practices connect directly to the SBOM, provenance, and signing attestations.

Honest framing

B5’s SDLC is its own attestation, not a substitute for yours.

Evidence about how B5 builds, inside your boundary.

This page attests to how B5 builds the libraries you embed — it does not replace your own secure-development obligations. Because B5 holds no customer data and runs inside your boundary, the SDLC evidence is the relevant surface, mapped to a framework your reviewers already apply.
