Application security audit
Secure code review, authentication and authorisation checks, exposed secrets and vulnerable dependency detection. Checks are selected based on project risks and the OWASP Top 10.

security audits
Protect your applications, APIs and Azure environments with focused technical audits and help fixing vulnerabilities.
Understand the code. Prioritise risks. Fix the root cause.
Why audit your application security?
A new API, changed user permissions or an Azure migration can expose data or business functions. A targeted audit helps understand risks before deployment, when taking over an application or after architecture changes.
We work with SMEs, software vendors and technical teams that need clear findings and a plan for fixing vulnerabilities. We agree on the scope based on the code and environments available and the resources needed.
Our areas of expertise
API security
REST API and API Management review: OAuth 2.0, OpenID Connect, JWT validation, resource-level permissions, endpoint protection, rate limiting and data validation.
Microsoft Azure security
We review Entra ID, permissions and access to resources, including Key Vault, managed identities, Azure Functions and API Management. Network settings, private access, logs and monitoring are reviewed within the agreed scope.
DevSecOps
Integrate static application security testing (SAST), software composition analysis (SCA) for open-source dependencies, and secret detection into Azure DevOps or GitHub Actions. Review CI/CD permissions, triage alerts and help remediate findings. Tools are selected during scoping.
.NET application audits
We review C# and ASP.NET Core code, including authorisation, input validation, secrets, dependencies and sensitive business logic. We also review data access, including Entity Framework where the project uses it.
Vulnerability remediation
Fix code, harden configuration and update dependencies. Validate fixes and add automated checks to reduce regressions.
.NET application security
A technical partner who understands your code, your cloud and your security challenges.
Our C# / .NET expertise helps trace a finding to its cause: an incomplete authorisation policy, access to another user’s resource, unchecked input or a secret in a configuration file. We also review business rules that automated tools may miss.
We explain risk conditions, propose a fix compatible with the architecture and define regression tests with your team. Explore our development expertise →
API and cloud service security
We trace a request’s journey: Entra ID identity, the token presented to the API, resource authorisation, Azure Functions execution and Key Vault secret access. This end-to-end view helps identify gaps between the intended architecture and deployed configuration.
Identity API Service Data & secrets
Private access, permissions and logs are reviewed within the authorised resources. Logs should support diagnosis without exposing tokens or sensitive data. Our Cloud & integration services →
Our audit methodology
- 01
Scoping
We review the architecture, objectives, permissions and scope. Environments, test accounts, testing windows, exclusions and conditions for stopping work are agreed in writing.
- 02
Analysis
We review the relevant code, configuration, dependencies, identities and entry points. Any active testing requires explicit authorisation.
- 03
Risk identification
We assess findings by severity, exploitability and business impact, explaining false positives and the limits of verification.
- 04
Audit report
We document the findings, supporting technical evidence and associated risks, with recommendations for fixes in order of priority.
- 05
Remediation and verification
Where agreed, we implement fixes, support your developers and verify the changes. We record any remaining risks and items that have not been retested.
All work is performed only within a client-authorised scope. Third-party systems also require their owner’s authorisation. Destructive or availability testing is not included by default.

A decision-ready summary
Scope, limitations, key risks and priorities explained to project owners.
A technical report your team can act on
Assessed findings, affected components, redacted evidence, authorised reproduction conditions and recommendations.
Remediation plan
Prioritised actions and validation criteria, plus code or configuration fixes and verification results where included in the engagement.
Support with remediation
Once a problem is identified, the next step is fixing it.
We can work with your developers to fix vulnerable code, restrict permissions, remove secrets from configuration or update dependencies. Changes follow your review and deployment process.
Verifying fixes and adding CI/CD checks turns the report into lasting improvements. The proposal clearly separates the audit, remediation work and verification.
Frequently asked questions
Is this a full penetration test?
The service focuses on targeted technical reviews of code, configuration, APIs and pipelines. Active tests, when needed, require specific scope and authorisation. A targeted audit does not automatically cover the entire IT system.
Do you need access to source code?
Code review requires limited access to agreed repositories. An Azure configuration review can be scoped separately. Required access and its duration are defined before starting.
Does an audit guarantee there are no vulnerabilities?
No. Conclusions apply to the scope, versions and conditions observed. Limitations and unverified items are included in the report.
What timeline and budget should I expect?
Timing and cost depend on the size of the codebase, architecture, available access and checks selected. After scoping, we provide a proposal setting out the work and deliverables.
Do you work in Lyon and remotely?
Audits can be organised remotely for businesses in France, including Lyon and Villeurbanne. Any on-site work is agreed during scoping; the registered office is in Paris.
