Attacks against APIs can range from discovering hidden, confidential endpoints to injection attacks against the underlying infrastructure. Due to their often-limited functionality, it’s often believed that they are not as important to test and protect. Because of this, they’re often a prime vector for attackers.

Scanning and manual testing will discover areas of weakness in your API, and from there we’ll provide clear instructions on how to fix them.

An often-overlooked part of your infrastructure

Everyone knows they need to conduct penetration testing of their web applications, but the APIs that underpin those applications, mobile applications or are used for other executive functions can often be forgotten.

Ensuring that they are secure is essential, even if the task can seem daunting. Speak with our expert team to find out how we can help you keep your APIs safe.

How we work


We determine your specific requirements before building a tailored proposal.


Our thorough testing simulates the attack methodologies of today’s most advanced hackers.


Our comprehensive reports impart clear, practical advice on how to address any weaknesses.


We offer ongoing support to guide you through the process of securing your applications. 

Everyone is a target

2022, Twitter reported an API breach that exposed the Personal Identifiable Information of 5 million users. Since then, information of more than 200 million more users freely appeared on a breach forum. This resulted in Twitter being sued under a class-action lawsuit and being investigated for a GDPR breach.

This breach was due to an API that was not properly secured. If one of the largest social media companies in the world can have a breach like this, so can anyone.

This breach was easily avoidable if the API had been properly secured. A thorough penetration test can help find these areas of weakness and assure security measures


How do we complete an API test?

We combine our in-house methodology with industry-standard tools and measures. This means that we adapt our testing to your API, while also assuring that we are focusing on the vulnerabilities that are relevant today. The OWASP Top 10 framework is applied as a starting point to all API tests, on top of that we strive to continually improve our testing methodology, ensuring that your API is tested to the highest standard.

Should I have any other tests alongside API testing?

APIs often feed into applications, be those web or mobile. Ensuring that these are tested, as well as the infrastructure supporting those applications, ensures the interface between the API and application is tested giving a well-rounded approach to security and an assurance for the entire application from beginning to end.

Will my services be disrupted?

We will never perform any testing with the intent to disrupt services. Furthermore, we encourage any testing to be completed against a non-production environment to ensure there is no disruption to live services.

Other services

Mobile Application Testing

86% of mobile applications have at least one vulnerability violating the OWASP Top 10. If these issues are exploited by cyber criminals or malicious users, it can have serious implications for an organisation, in terms of both cost and reputational damage.

Product Assessment

If you develop a software product or service, are you confident that it’s as secure as it can be? Your clients rely on you to keep their data secure, so if you’ve not had your product or service independently assessed, your reputation is at risk if a vulnerability is discovered.
