Secure Code Review
Manual review of the code that matters most: authentication, authorization, data handling and anything that touches money or customer data. Findings come at line level, with a suggested patch in your language.
When it's needed
Code review finds what testing from the outside can miss, such as logic that only fails under specific conditions.
- Before releasing a sensitive feature such as payments or permissions
- After a penetration test, to find the root cause of a class of issue
- When a critical service has grown faster than its reviews
What we assess
- Authentication and authorization
- Who can do what, and whether the code enforces it everywhere.
- Input handling and injection
- Every path from user input to a query, command or template.
- Cryptography and secrets
- Algorithms, key handling and secrets in code and configuration.
- High-risk data flows
- Where sensitive data is read, stored, logged and sent.
How we work
- 01
Discover
Walk through the architecture and agree the highest-risk modules.
- 02
Validate
Review the code by hand and confirm each issue, running it where needed.
- 03
Prioritize
Rank findings by exploitability and what they would expose.
- 04
Reduce
Suggest patches, walk your engineers through them and review the fixes.
What you get
- Line-level findings
- The exact location, the reason it matters and how it could be exploited.
- Suggested patches
- Written in your language and style.
- Patterns that prevent recurrence
- So the same class of issue does not come back.
- A walkthrough with your engineers
- To explain the findings and answer questions.
Common questions
Ask us something elseDo you need write access to our code?
No. Read-only access to an agreed commit is enough.
What do you need from us to get started?
To start, we usually need read-only repository access at an agreed commit; a 60-minute architecture walkthrough; the modules you consider highest risk; and build instructions, if we need to confirm a finding by running it. We confirm the exact list during scoping.
Is this the same as running a SAST tool?
No. Tools find patterns; manual review follows the logic. We may use tools to decide where to look, but every finding is confirmed by hand.
