TL;DR: Source code analysis spans broad code-quality review, while SAST focuses on security vulnerabilities, according to Aptori's blog post on static analysis. Software teams need both disciplines to catch defects early without confusing maintainability checks with exploitability checks.
Editorial analysis by NHI Mgmt Group, based on content published by Aptori: “The Difference Between Source Code Analysis and SAST”.
Key questions
Q: How should teams prioritise static analysis findings in CI/CD?
A: Prioritise static analysis findings by exploitability, code reachability, and whether the issue sits in production-bound paths, then fix secrets exposure, injection flaws, and unsafe deserialisation first.
Q: How can repository secrets be found before attackers use them?
A: Repository secrets can be found before attackers use them by scanning the full Git history for committed keys, tokens, certificates, and config files, not just the latest branch tip.
Q: How does SAST differ from general source code analysis?
A: SAST is a security-focused subset of static analysis that looks for exploitable code patterns such as injection flaws, unsafe deserialization and weak authentication handling.
Practitioner guidance
- Separate quality findings from security findings Route style, maintainability and correctness issues to engineering workflows, while sending exploitable security defects to AppSec triage with distinct severity and SLAs.
- Tune static rules for exploitability Prioritise rules that detect injection, unsafe deserialization, exposed secrets and authorisation flaws so security teams are not buried in low-value noise.
- Scan repository history for leaked credentials Include full Git history, archived branches and mirrored repositories in secret searches, because exposed tokens often survive long after the visible code changes.
Bottom line: Source code analysis and SAST solve different governance problems, and organisations weaken both controls when they treat them as interchangeable.

Source code analysis and SAST are not competing labels for the same control. Source code analysis is the wider review discipline, while SAST is the security subset that looks for exploitable patterns before deployment. Conflating the two creates governance drift: teams think they have security coverage when they only have broad code review. The better model is to treat quality and exploitability as separate control objectives with separate evidence.
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: What is the difference between a linter and SAST?
A: A linter checks code style, formatting, and simple rule violations, while SAST analyses source code for security flaws such as injection, unsafe deserialisation, and hard-coded secrets. Linters usually operate on syntax or patterns, but SAST tries to trace code paths and data flow to identify vulnerabilities before deployment.
