TL;DR: SAST catches code-level flaws at commit time while DAST finds runtime issues like auth bypass, but Arnica’s guide argues that neither category alone covers the full OWASP Top 10 and that secrets scanning, SCA, and deployment-time testing must run in parallel. The practical shift is to measure exploitability, blast radius, and mean time to remediate instead of treating scanner output as a compliance checklist.

Questions worth separating out
Q: How should security teams implement DAST in CI/CD pipelines?
A: Start by making DAST part of the release workflow, not a separate review process.
Q: Why do application secrets create identity risk as well as appsec risk?
A: Because secrets are machine credentials.
Q: What do security teams get wrong about SAST and DAST coverage?
A: They often treat the tools as substitutes rather than complementary controls.
Practitioner guidance
- Implement pull-request secrets detection Block merges when API keys, tokens, or certificates appear in source, configs, or generated artefacts, and route each hit to the owning team for immediate revocation and rotation.
- Map testing controls to the SDLC stage Run SAST at commit time, SCA on every dependency update, and DAST against staging or pre-production before release.
- Prioritise findings by reachability and exploitability Triage issues by whether the vulnerable code path is reachable, whether the flaw can be chained with exposed credentials or weak authentication, and how far the blast radius extends if it is abused.

Arnica's full blog post covers the operational detail this post intentionally leaves for the source:
- The full testing matrix that maps SAST, DAST, SCA, and secrets scanning to pipeline stages and deployment gates.
- The article’s tool-selection guidance for AppSec teams choosing between developer-first and platform-wide coverage models.
- Examples of how Arnica ranks findings by reachability and exploitability rather than raw alert counts.
- The detailed comparison of testing categories against OWASP Top 10 coverage gaps.

SAST and DAST are complementary control planes, not competing product categories. Static analysis finds code defects before execution, while dynamic testing exposes behaviour that only appears at runtime. The market habit of comparing them as substitutes obscures the real governance question: which attack surface is covered at which lifecycle stage. Teams that treat them as interchangeable will always leave gaps between commit, build, and deployment. The practitioner conclusion is to assign each test type to the control boundary it can actually observe.
A question worth separating out:
Q: What should teams do when AppSec findings involve secrets or access tokens?
A: Treat the issue as an identity event, not only a code defect. Revoke the exposed credential, rotate the secret, identify every system that could have used it, and verify that the token was not copied into other environments. If the access path is unclear, assume broader exposure until proven otherwise.
