TL;DR: SAST and DAST each address different parts of application risk, with SAST finding code flaws early and DAST validating runtime behaviour after deployment, according to OXSecurity. The real issue is not choosing one over the other, but managing false positives, late-stage remediation, and the gaps automated scanning still leaves behind.
Editorial analysis by NHI Mgmt Group, based on content published by OXSecurity: “SAST and DAST Tools: Still Essential Security Testing Tools in 2025”.
Key questions
Q: How should teams combine SAST and DAST in a secure development programme?
A: Use SAST to catch insecure code patterns early and DAST to confirm how the running application behaves under attack conditions.
A: False positives force developers to spend time proving that an alert is harmless instead of fixing real issues.
Q: What do teams get wrong about relying on automatic application scanning alone?
A: The common mistake is treating scanners as complete security coverage.
Practitioner guidance
- Embed SAST in pre-merge pipelines Run SAST before code reaches QA so developers can fix high-confidence findings while the change is still local and cheap to remediate.
- Use DAST as a release gate for runtime behaviour Test authenticated flows, misconfigurations, and business logic in a staging environment that mirrors production closely enough to expose real runtime weaknesses.
- Triangulate false positives against runtime context Prioritise findings that remain exploitable after deployment and de-prioritise static alerts that disappear once the live environment is considered.
Bottom line: SAST and DAST are complementary controls that see different phases of application risk, and neither is sufficient as a standalone AppSec strategy.

AppSec still fails when organisations treat static and dynamic testing as substitutes rather than control layers. SAST and DAST are both necessary because they observe different risk states. One sees code before it runs, the other sees behaviour after deployment. The governance mistake is expecting a single test moment to represent the whole exposure picture, which is why unresolved application risk often survives into production.
A few things that frame the scale:
- Internal repositories are 6x more likely to contain secrets than public ones (32.2% vs 5.6%), contradicting the assumption that private repos are safe, according to the State of Secrets Sprawl 2026.
A question worth separating out:
Q: How should organisations decide when to add human-led testing to AppSec?
A: Add human-led testing when the application includes complex business logic, custom protocols, high-value authentication flows, or dependencies that automated tools cannot validate well. That is the point where the question is no longer whether a scanner found a weakness, but whether an attacker could chain the weakness into meaningful compromise.
