Specialist web app testing and API testing

Web application penetration testing simulates the actions of a hacker to critically assesses your security vulnerabilities, weaknesses and technical misconfigurations that an attacker would target. In this way, web app pen tests allow you to act immediately, removing vulnerabilities in your web apps and APIs, whilst your business remains operational.

Testing your web applications for security flaws is an important part of maintaining secure development and operational practices, as well as meeting numerous compliance mandates. Put simply, web app pen testing is the best way to ensure you stay ahead of the hackers and keep your business protected.

Different types of web app pen testing

Web app pen testing can be carried out from either an authenticated or unauthenticated standpoint, which models different types of attack. Target Defense recommends a blend of authenticated and unauthenticated testing to make sure all your web app security risks are uncovered.



Authenticated web app testing tests the security of your web app as if an attacker has breached your external security or has phished valid user credentials. This is a detailed test which uncovers the real damage a successful cyber attack could cause to your business.



Unauthenticated web app testing shows what damage a cyber criminal could do to your business from a publicly available webpage, without having access to valid user credentials. Unauthenticated web app pen tests can discover vulnerabilities available to anyone with access to the web app, such as a login portal.



If your business uses a web-based API to deliver its services, then you need API pen testing. Testing your APIs in addition to your web apps is standard best practice, and combination pen tests are available to test web apps and APIs together.
