42Crunch

42Crunch provides a unified platform to help you secure your entire API lifecycle from design to runtime. You can automatically audit your OpenAPI definitions to find security gaps before writing a single line of code. By integrating security directly into your development workflow, you ensure that every API you deploy is hardened against common threats like broken object-level authorization and data injections.

The platform enables you to enforce consistent security policies across your entire API inventory using a micro-API firewall. You can monitor traffic in real-time and block malicious requests without manual intervention. It is designed for security and development teams in regulated industries who need to scale their API security without slowing down their release cycles.

Metasploit

Metasploit helps you think like an attacker so you can stay one step ahead of security threats. You can use the world’s most used penetration testing framework to find weak spots in your defenses, simulate real-world attacks, and verify that your security patches actually work. It simplifies the complex process of exploitation by providing a massive library of tested code and automated tools that handle the heavy lifting for you.

You can choose between the open-source Framework for command-line power or the Pro version for a guided, graphical experience. Whether you are conducting a quick vulnerability scan or a deep-dive security audit, the platform provides the data you need to prioritize risks. It is a go-to solution for security consultants, internal red teams, and IT managers who need to prove where their network is vulnerable.
