Our experts apply current attack techniques to assess REST, SOAP, and GraphQL APIs for weaknesses, misconfigurations, and business logic flaws.
Through static source code reviews, SAST, and DAST, we harden your SDL, identifying vulnerabilities at every stage of development before they reach production.

The Benefits of API Penetration Testing
The Benefits of API Penetration Testing
The Benefits of API Penetration Testing
APIs introduce unique security risks and securing them requires in-depth testing. With expert application security testing support, you can:
Verify that API requests and responses are encrypted with strong ciphers and correctly implemented.
Identify weaknesses in authentication and authorisation mechanisms, including broken token validation, improper role enforcement, and missing access controls.
Uncover vulnerabilities that could enable privilege escalation, workflow bypass, or unintended exposure of sensitive data.
Types of API Penetration Tests
Known as “white box,” it evaluates security from the perspective of a compromised or malicious user with valid API credentials, revealing access‑control flaws, privilege‑escalation risks, and excessive data exposure.

Expertise and efficiency
We combine human expertise for in-depth analysis with efficient automation for ongoing scanning
GuardNest platform
Simplifies vulnerability management with real-time reporting, remediation tracking, and expert advice
Compliance support
We support adherence to relevant industry regulations and standards to avoid the risk of non-compliance
Remote testing
Our consultants offer thorough internal and external testing without on-site presence
Wide range of expertise
We offer testing across everything from infrastructure and mobile applications to cloud and IoT environments
Methodology
We ensure testing has both depth and breadth by aligning with recognised methodologies such as CREST, OSSTMM, OWASP, and NIST.
This ensures a structured, consistent approach grounded in best practice and real-world threat intelligence.
We follow a clear seven-step process designed to deliver rigorous testing, meaningful insight, and practical remediation guidance at every stage.
We listen to your needs and develop a tailored project strategy, producing a scope that meets your unique requirements.
We assess your target systems and design a testing approach based on: where your organisation is most vulnerable, the most effective and efficient attack techniques, and how to conduct the test while ensuring your organisation remains protected.
We scan and enumerate the defined targets to identify existing vulnerabilities. This includes listening for open ports, identifying running services, and developing an attack plan based on the scan results.
Our consultants assess how deeply they can access your systems using leading industry techniques, custom-built tools, and their first-hand experience.
If a consultant successfully exploits a vulnerability, they assess its severity. This involves determining which assets and networks can be accessed and how much information can be gathered. Your vulnerabilities are then ranked from low to critical in GuardNest.
Findings are published in a report on GuardNest, organised by category and type, with remediation advice for each exploit and vulnerability. On request, we also arrange debrief calls to review identified risks in detail and discuss remediation.
Your GuardNest licence includes continuous external infrastructure scanning to minimise risk between tests. We also offer a remediation check service, and every engagement includes a full consultative approach to ensure ongoing support even after the project is complete.

FAQs
It's a comprehensive assessment of your application programming interfaces (APIs), the protocols that allow software systems to communicate, by simulating real-world attacks to uncover vulnerabilities before they can be exploited.
Static Application Security Testing (SAST) involves automatic scanning for risks within application code before the software is released to prevent data exposure, unauthorised access, or system compromise.
Dynamic Application Security Testing (DAST) simulates real-world attacks against a live application while it is running to highlight issues such as improper input handling or broken authentication that could be exploited.
REST, SOAP, and GraphQL are different API approaches that define how systems exchange data, ranging from simple and flexible (REST), to structured and tightly controlled (SOAP), to highly efficient and tailored data retrieval (GraphQL).
