Welcome to Managed Application Security (MAS)

Eliminate exploitable application vulnerabilities with guidance from our appsec experts.


Despite your developers’ best efforts and the security gates you’ve placed throughout the software development lifecycle (SDLC), application vulnerabilities are inevitable. Therefore, it’s critical to prioritize the risks most susceptible to exploitation by real threat actors, and reduce vulnerabilities found in your runtime applications. This is where dynamic application security testing (DAST) comes in. Rapid7 Managed Application Security (AppSec) provides the appsec experts, technology, and processes needed to effectively identify exploitable application vulnerabilities with the context developers need to fix issues before they appear in production. Leveraging the industry’s leading DAST scan engine and attacker intelligence, our team of experts continuously test and provide remediation guidance so you can be confident that your applications are secure—now and moving forward.
