Making it simple for developers to find, triage, and fix application security bugs
About StackHawk
StackHawk is a startup that specializes in application security testing, specifically designed for developers. The company provides a tool that helps engineers identify and fix security vulnerabilities in their code before it goes live. This is achieved through powerful automation and integration capabilities, allowing security tests to be seamlessly integrated into the development process.
StackHawk operates in the cybersecurity market, focusing on dynamic application security testing (DAST). This type of testing involves running applications and APIs (Application Programming Interfaces) to uncover security weaknesses. The company supports a wide range of API types, ensuring comprehensive security coverage for various applications and microservices.
The primary clients of StackHawk are software development teams and engineering departments within organizations that prioritize secure software delivery. These clients benefit from the ability to detect and address security issues early in the development cycle, which helps in shipping secure software faster and reduces the need for disruptive fixes later on.
StackHawk's business model is likely subscription-based, where clients pay for access to the security testing tool and its features. The company generates revenue by offering different pricing tiers based on the size of the development team, the number of applications tested, and the level of support required.
In summary, StackHawk empowers developers to take control of application security by integrating security testing into their continuous integration and continuous delivery (CI/CD) pipelines. This proactive approach ensures that security vulnerabilities are addressed promptly, enhancing the overall security posture of the software being developed.
