Probely

Probely is a web application and API security scanning company that provides vulnerability management tools designed to integrate into the software development lifecycle (SDLC). The platform focuses on automated web vulnerability scanning, enabling development and security teams to identify and remediate security weaknesses in web applications and APIs during and after development. Probely's core offering is a web vulnerability scanner that assesses web applications for common security flaws such as unvalidated input, session management issues, and other known vulnerability classes. The platform supports scanning of both external and internal assets, including cloud-hosted services and internally developed applications. The company targets a range of organizations, from small and medium-sized businesses to enterprises, with an emphasis on helping engineering and security teams collaborate on application security. Probely advocates for a "shift-left" approach, encouraging security testing to be incorporated earlier in the development process rather than treated as an afterthought. In addition to its scanning capabilities, Probely publishes educational content around attack surface management (ASM) and vulnerability management (VM), addressing topics such as the differences between vulnerability scanning and penetration testing, continuous monitoring practices, and the evolving legal and regulatory accountability of engineering leadership for SDLC security. The platform also addresses compliance considerations, including SEC cybersecurity disclosure requirements. Probely's tooling is positioned for teams seeking to automate and operationalize application security testing within their existing development workflows.
