Source code audits
Source code audits provide deep insights into the security and quality of your software. Our auditors systematically check source code for vulnerabilities, insecure functions and possible compliance violations. By combining tool-supported analysis and manual checks, we uncover risks that automated scanners alone cannot detect. This not only increases security, but also the maintainability and stability of your applications.
Why Secure SDLC & DevSecOps?
Many vulnerabilities arise directly in the source code and remain undetected in traditional tests. An audit makes these risks visible before they can be exploited by attackers. At the same time, a structured review improves code quality and facilitates maintenance and further development in the long term. In addition, audits help to demonstrably fulfill regulatory requirements such as ISO 27001, NIS2 or the CRA.
Our audit approach
A source code audit at OTARIS combines automated analyses with manual checks by experienced auditors. While tools reliably detect known vulnerabilities or insecure libraries, manual analysis uncovers complex logic errors that automated processes do not recognize.
We pay particular attention to security-critical areas such as authentication, authorization, input validation, error handling and session management. Each finding is clearly described, evaluated according to criticality and provided with concrete measures. The results are summarized in a structured report that is understandable for developers, management and auditors alike.
Typical findings in source code audits
In almost every audit, we come across recurring patterns that can make life easy for attackers. Some vulnerabilities appear inconspicuous at first glance, but have a significant impact on security and stability.
Source code audits with OTARIS
Give us a call or send us a message. We will contact you immediately to discuss the next steps.
Hard-coded passwords or secrets
Access data stored in the source code can easily be tapped and misused.
Insecure libraries or functions
The use of outdated or insecure libraries opens up known attack paths.
Missing input validation
Unchecked inputs allow classic attacks such as SQL injection or cross-site scripting.
Error in session or error handling
Insecure sessions or unclear error messages give attackers valuable information about the internal logic.
Your advantages with OTARIS
With a source code audit from OTARIS, you gain a clear view of the security-critical areas of your software. Our auditors have in-depth technical knowledge of both development and IT security and combine automated procedures with manual analyses. In this way, even complex logic errors that standard tools do not detect become visible.
Our reports are structured transparently, prioritize the findings according to criticality and contain concrete recommendations for action that can be directly integrated into development processes. Thanks to our experience in safety-critical projects in various industries, we adapt each audit individually to your systems and requirements. The result is resilient code that supports security, quality and compliance in the long term.
