SAST, Static Application Security Testing
Static analysis of source code, surfacing vulnerabilities early in the SDLC, before they reach production.
SAST analyses source code rather than the running application. That gives it visibility into code paths runtime testing cannot reach, error handlers, batch jobs, scheduled tasks, internal admin functions, and lets it surface findings before they ever ship.
As with DAST, the value of SAST is what surrounds the tool. Raw scanner output is noisy by nature and most teams that have tried "just run SAST" abandon it within a release cycle. Our SAST engagements layer consultant triage, contextualisation against the application, and exploitability prioritisation on top, so the output is something engineering can act on.
SAST works best as part of a secure-SDLC programme: gated in CI/CD, with deeper periodic reviews driven by consultants.
What's at stake.
Static analysis finds what dynamic cannot
Code paths never reached during DAST scans still exist in the binary and can be invoked by an attacker. SAST is the only practical way to see them.
Cost-to-fix scales sharply with time
A finding caught at commit time costs minutes. The same finding caught in production may already have been exploited and requires incident response.
What we test.
Vulnerability detection
- Authentication and authorisation logic
- Input validation and output encoding
- Configuration and secrets handling
- Session management
- Cryptography and key handling
Programme support
- Secure SDLC integration
- CI/CD pipeline policy gating
- Compliance verification (PCI DSS, ISO 27001)
- Developer-friendly remediation reporting
- Tool tuning to your stack and false-positive reduction
A structured, intelligence-led path through every engagement.
Every engagement follows the same disciplined path through the Velocity platform, so quality, traceability, and reporting are consistent across teams.
Scoping
Define assets, environments, Rules of Engagement, and acceptance criteria with the technical and security stakeholders.
Execution
Manual and tool-assisted testing by CREST-accredited consultants, with evidence captured at each step.
Validation
Every finding is reproduced, risk-rated under CVSS, and confirmed by a second consultant before reporting.
Reporting
Cryptographically signed reports with test-case traceability, severity ratings, reproduction steps, and remediation guidance.
Debrief & Retest
Stakeholder walk-through of findings, prioritisation support, and a retest cycle on remediated issues.
Mapped to recognised baselines.
Common buyer questions.
Will SAST find authorisation flaws? +
Partially. SAST can catch missing role checks and obvious data-flow patterns, but logic-driven authorisation flaws (multi-step, role-confused, business-logic) still require manual testing.
Which SAST tooling do you use? +
Engagement-dependent, selected to match the language ecosystem and integration model. We are tool-agnostic; what matters is the triage and methodology, not the brand of scanner.
