Secure code review services for safer releases
Find code-level security risks before release, with findings your developers can fix and prove.
Our verified credentials
When code review becomes necessary
Secure code review fits when the risk sits inside the source code, not only at the exposed surface.
Before a major release
Selected features handle authentication, authorization, payments, sensitive data, or external APIs.After recurring security findings
Scans or tests keep pointing to issues that need source-level validation and fix guidance.Before buyer security review
Highlight Unique Selling Propositions with a short summary of the key feature and how it benefits customers.When developers need secure coding guidance
Findings must be specific enough to assign, implement, and retest.When inheriting a codebase
Ownership changes, legacy assumptions, or outsourced code need security validation before more work continues.
Code-level risk is hard to prove late
Security review becomes expensive when the first clear finding appears after code is already merged, released, or questioned by a buyer. The issue is not only whether a vulnerability exists. The issue is whether your team can find it, prioritize it, fix it, and show evidence that it was closed.
-
Logic flaws stay hidden
Authorization, data flow, and business-rule mistakes often require context. A scanner can point to patterns; it cannot always prove what the code allows.
-
Release pressure narrows review
Begin with 1 FTE or a small pod, then scale into a dedicated team when you’re ready—without rebuilding the setup every quarter.
-
Findings stall without fix guidance
A finding that only says what is wrong leaves developers to infer the fix. Secure code review should return remediation guidance they can assign and implement.
-
Evidence gets scattered
Tickets, scan exports, and comments are not enough for due diligence. The useful output is a report showing what was reviewed, what was found, and what was closed.

What the review checks in the code
| Focus area | What is reviewed | Output |
|---|---|---|
| Access and data flow | Authentication, authorization, role checks, data handling, and encryption patterns in selected code paths. | Validated findings with affected code area, severity, and fix direction. |
| Input and API behavior | Input validation, injection risk, serialization, API boundaries, error handling, and unsafe assumptions. | Developer-ready remediation guidance tied to the application context. |
| Secrets and dependencies | Secrets exposure, package risk, dependency use, repository hygiene, and selected CI/CD security signals. | Prioritized risks that can be assigned, remediated, and retested. |
How the review runs
-
1. Scope
Agree the codebase, language, modules, release context, review depth, and security questions to answer.
-
2. Access
Set up repository snapshot or controlled access, plus documentation needed to understand architecture and data flow.
-
3. Review
Run SAST-supported analysis and manual validation against the scoped application context and relevant OWASP/CWE guidance.
-
4. Report
Deliver validated findings, severity, affected area, impact, remediation guidance, executive summary, and evidence summary.
-
5. Retest
Validate fixes and provide closure evidence where retesting is included in scope.
Review scope
Choose the level of code evidence your release needs.
| Area | Feature | App | Release |
|---|---|---|---|
| Best fit | Critical feature | Selected application | Pre-release check |
| Review focus | Auth, API, data flow | High-risk modules | Change set + core paths |
| Method | SAST + manual | SAST + manual | SAST + manual |
| Deliverables | Findings + fixes | Report + summary | Report + closure evidence |
| Retest | Optional | Optional | Included if scoped |
| Remediation support | Scoped separately | Scoped separately | Scoped separately |
What your team receives
Code-level findings report
Validated findings with affected area, severity, exploit relevance, and practical impact. Findings are prioritized so engineering can decide what to fix first.
Developer-ready fix guidance
Remediation guidance that names the unsafe pattern and the expected correction. The goal is to make findings assignable, not just visible.
Evidence and closure pack
Executive summary, evidence summary, and retest or closure note where scoped. The pack shows what was reviewed, what was fixed, and what remains open.
