Trust boundaries
Where untrusted data, users, services or components cross into security-sensitive operations.
Singapore / Secure implementation
Source code security review.
Examine security-sensitive implementation paths in context so developers can see where trust assumptions fail and how to address them.
Discuss your scope01 / Service fit
Review the implementation behind the control.
Dynamic testing shows how a running system behaves. A source code review can examine the implementation paths behind authentication, authorisation, data handling and other security-sensitive behaviour, including conditions that may be difficult to reach consistently from the outside.
This service is suited to teams reviewing a critical component, preparing a significant release, addressing a higher-risk workflow, or seeking independent review of an existing codebase. The work may complement penetration testing, but the two services answer different questions.
The review scope is bounded by repositories, branches, components, languages and priorities agreed in advance. It is not presented as an unlimited review of every line or dependency.
02 / Scope
What we review.
Coverage is selected around the security responsibilities of the agreed components and the context available to the reviewer.
Authentication and sessions
Identity verification, token and session handling, account recovery and relevant state transitions.
Authorisation
Role, object and function-level access checks, including how permissions are applied across code paths.
Input and output handling
Validation, parsing, encoding, file operations and use of untrusted values in sensitive functions.
Sensitive data and secrets
Security-relevant storage, logging, transmission and configuration patterns within the agreed components.
Critical workflows
Business-sensitive state changes, integration calls, error handling and assumptions that affect security outcomes.
03 / Method
How the review runs.
The review starts with architecture and risk context, then follows security-relevant paths through the agreed code.
- 01
Confirm the code boundary
Agree repositories, branches or commits, components, languages, build context, supporting documentation, priorities and exclusions.
- 02
Understand the design
Map important data flows, trust boundaries, roles, sensitive operations and the security responsibilities of reviewed components.
- 03
Trace critical paths
Review selected implementation flows and validate findings against surrounding code and available runtime context where appropriate.
- 04
Report with references
Document affected code locations or components, conditions, impact, severity rationale and practical remediation direction.
- 05
Clarify and verify
Discuss findings with the development team and review agreed changes or related runtime behaviour within the retest scope.
04 / Deliverables
Findings developers can locate.
The report connects security outcomes to the relevant implementation context instead of stopping at a generic weakness category.
Review context
Repositories, versions, components, assumptions, exclusions and the security-sensitive areas prioritised.
Code-referenced findings
Affected paths or components, conditions, supporting evidence, impact and severity rationale.
Remediation guidance
Implementation-focused recommendations, developer clarification and outcome of agreed fix verification.
05 / Boundaries
Assumptions and exclusions.
The value of the review depends on a precise code baseline and enough context to interpret it correctly.
Defined baseline
Repositories, branches or commits and relevant generated or vendored code are identified so findings refer to a known version.
Available context
Architecture, build instructions, configuration assumptions and access to relevant team members may be needed to validate security behaviour.
Explicit exclusions
Unlisted repositories, third-party code, exhaustive dependency review, operational configuration and runtime-only behaviour are excluded unless specifically included.
A source code review covers the agreed baseline and priorities. It is not a guarantee that every weakness has been found, a full correctness review or a certification that the software meets a regulatory standard.
06 / Related services
Validate code and runtime behaviour.
