Your attack surface is the sum total of all attack vectors that can be used against your perimeter defenses. It is simply the amount of information that you are exposing the outside world. The attack surface is the most important thing hackers will need to exploit to break into your network. When attacking targets, professional hackers usually follow the cyber kill chains. Typically, the first step in this process is to survey the target's attack surfaces. This is called advanced reconnaissance. By reducing the attack surface, you can reduce the risk and prevent attacks from ever happening. The cyber kill chain is a method for categorizing and tracking all stages of a cyberattack, from early reconnaissance to the exfiltration data.

You can either submit API test requests through the user interface form or trigger the EthicalCheck API using tools like cURL or Postman. To input your request, you will need a public-facing OpenAPI Specification URL, an authentication token that remains valid for a minimum of 10 minutes, an active license key, and your email address. The EthicalCheck engine autonomously generates and executes tailored security tests for your APIs based on the OWASP API Top 10 list, effectively filtering out false positives from the outcomes while producing a customized report that is easily digestible for developers, which is then sent directly to your email. As noted by Gartner, APIs represent the most common target for attacks, with hackers and automated bots exploiting vulnerabilities that have led to significant security breaches in numerous organizations. This system ensures that you only see genuine vulnerabilities, as false positives are systematically excluded from the results. Furthermore, you can produce high-quality penetration testing reports suitable for enterprise use, allowing you to share them confidently with developers, customers, partners, and compliance teams alike. Utilizing EthicalCheck can be likened to conducting a private bug-bounty program that enhances your security posture effectively.
