New release with auth or API changes
When authorization, APIs, sessions, roles or user access flows change.
Source code review
Reduce risk before a release, audit or major product change. We review web, API and SaaS product code to identify authorization, data handling, secrets and business logic risks early.

When code review brings the most value
When it makes sense
Legacy or fast-grown codebase
When the product grew quickly, parts of the code are inherited or security decisions were made under time pressure.
Before an audit, acquisition or investment
When a technical basis is needed for a decision, vendor assessment or security posture validation.
Where risk often appears
Critical business logic in code
When the code handles payments, pricing, limits, orders, files or other sensitive decisions.
Payments and third-party integrations
When payments, external APIs, webhooks or other services affect data flows.
When risk level must be understood quickly
When you need to see where the biggest code-level risks are and where to start.
How code review works
Define scope
Get code access
Identify risk areas
Deliver findings
Discuss action plan
We agree which part of the codebase should be reviewed, which features matter most, what technologies are used and how deep the review should go.
We align secure access, repositories, documentation, environment context and the boundaries followed during the review.
We analyze authorization, data handling, configuration, secrets and business logic areas where real risk can appear.
Findings are presented clearly: what was found, why it matters, under which conditions it works and what priority it should receive.
We discuss recommendations with the team, help prioritize remediation and decide whether a broader review is worth doing.
Limited-time offer
Free 1-day source code review
If you are not sure whether a full whitebox review is the right first step, start with a limited one-day review.
This is not a full audit and does not replace a complete source code review. It is a limited assessment designed to show value quickly and help decide on next steps.

Who it is for
SaaS owners, CTOs and small project teams that want to quickly understand whether the code shows early security risk signals.
What is checked
A limited part of the codebase: authorization logic, data handling, secrets, configuration and clearly visible risk paths.
What you get
A short summary of observed risk signals and a recommendation on whether a full source code review is worth doing.
What you receive
Code risk summary
We clearly show which areas of the code contain the most important security risk signals.
Risk path in code
The technical team sees how the issue appears in code and under which conditions it can have impact.
Business impact
We explain what the risk means for data, user access, reputation or business process.
Remediation guidance
Recommendations focus on practical changes in code, configuration or process.
Team walkthrough
After the review, findings, priorities and realistic remediation order can be discussed.
Next-step plan
If many risk signals appear, we help decide whether a full source code review or retest is needed.
Common questions
What is included in the free 1-day source code review?
It includes a limited review of an agreed code area, identification of early security risk signals and a short conclusion on whether a broader review is worth doing. It is not a full audit.
What access is needed for code review?
It is enough to send the agreed code files or temporarily provide access to the repository.
How is source code review different from penetration testing?
Penetration testing assesses the system from the outside, while code review exposes internal logic where authorization, data handling or configuration risks may be hidden.
How long does source code review take?
The free limited review takes 1 business day. A broader review depends on scope: for example, one authorization module or API area may take a few days, while a larger SaaS product or several critical features are scoped individually.
