Secure Code Review
Static analysis tools find patterns. They do not find business logic flaws, and they generate enough noise that real issues get buried. Astra combines tooling with manual review by people who read code for a living — tracing input paths, checking where sanitisation actually happens, and reporting the root cause rather than the symptom.
What you get
Outcomes, not activity.
- Root cause, not just the line numberFindings explain why the pattern is unsafe in your codebase and what the correct construct is, so the same class of bug stops recurring.
- Input path tracingEvery entry point is followed to the sinks it can reach — injection, deserialisation, path traversal, command execution — and the sanitisation between them is verified.
- Dependency riskThird-party libraries are checked against known CVEs, and the ones you actually invoke are separated from the ones you merely ship.
- Cryptography and secretsKey handling, algorithm choice, hashing and hard-coded credentials reviewed against current practice rather than the practice of the year the code was written.
How it runs
A defined sequence, agreed up front.
You know what happens in each stage, who is involved, and what lands at the end of it before the engagement starts.
- 01
Context
We start with the application's threat model, trust boundaries and the parts of the codebase that handle authentication, authorisation and data.
- 02
Automated pass
Static analysis establishes breadth and highlights candidate areas. Its output is triage material, not the report.
- 03
Manual review
Reviewers trace input paths, examine business logic, and inspect the areas automation is weakest on — authorisation, state handling, and race conditions.
- 04
Validation and reporting
Findings are confirmed, ranked, and written up with a concrete remediation for each, followed by a session with the development team.
Deliverables
What lands on your desk.
Written for two audiences: the engineers who have to fix it and the executives who have to fund it.
- Findings with file, line, data flow and root cause
- Remediation guidance with corrected code patterns
- Dependency and known-CVE assessment
- Secrets and cryptography review
- Developer walkthrough session
