Expose your API with confidence

API Security Testing Services

Our API penetration testing services cover an extensive attack surface that includes OWASP’s Top 10 vulnerabilities in order to identify the most important risks found in modern APIs regardless of the technologies it was built on.

What is API Security Testing?

API Penetration Testing is the primary assessment used to identify and address vulnerabilities in Web services that could be exploited by hackers for malicious purposes, using the same tools and techniques. Our API penetration testing services simulate a real cyberattacking targeting your Web services and offer an accurate representation of your API security by presenting several real-world opportunities for hackers to circumvent your security measures and launch additional attacks.

OWASP Top 10 API Vulnerabilities

Our API Penetration Testing combines both automatic and in-depth manual testing techniques. We use OWASP’s API security standard as a baseline for our testing methodology in order to identify vulnerabilities unique to each API.


Our API Security Testing Methodology

API security testing approach is based on manual techniques and goes beyond a typical scan, allowing you to identify complex vulnerabilities present in modern APIs. Here is a breakdown of our approach divided into three distinct types of tests:

Security Assessment

Our experts validate that your API meets various security requirements. For instance, authorization parameters and data access conditions are assessed to determine how the API handles permissions.

Penetration Testing

We attempt to breach your API by circumventing user privileges and bypassing authentication functions to identify technical vulnerabilities that allow hackers to further infiltrate your systems.

Using various attack methods commonly deployed by hackers, we manipulate API requests and parameters to identify vulnerabilities that can be exploited to compromise your security.


Improve Your API Security

In order to maximize the identified vulnerabilities, our extensive attack surface covers various types of exploits commonly used by hackers to breach your API:

Parameter tampering

Fuzz testing

Endpoint authorisation

XSS Attack

Command injection

Endpoint authentication

CSRF attack

Man-in-the-middle attack

Need Help To Assess And Improve Your Cybersecurity?

Internal API penetration testing is a type of network penetration testing designed to identify and fix vulnerabilities within internal network infrastructures by replicating the same techniques used by malicious business partners or disgruntled employees attempting to breach your network from within. 

Internal Penetration Testing is highly recommended to conduct an internal pentest at least once a year or following any major changes to the infrastructure to stay on top of the latest hacking methods for network penetration testing.

Conducting Network Testing is also required by various standards, such as PCI-DSS, ISO27001, and SOC 2.
