Application Security (AppSec)

Application security (AppSec) encompasses the measures taken to improve the security of applications by finding, fixing, and preventing vulnerabilities. It spans the entire software development lifecycle — from secure design and coding practices through testing, deployment, and ongoing monitoring. AppSec is distinct from network or infrastructure security in its focus on the software layer.

Modern AppSec programs employ multiple testing methodologies: Static Application Security Testing (SAST) analyzes source code for vulnerabilities, Dynamic Application Security Testing (DAST) tests running applications, Software Composition Analysis (SCA) identifies vulnerable dependencies, and penetration testing provides the deepest assessment by simulating real attacks. An effective program layers these approaches for comprehensive coverage.

How APVISO helps with this: APVISO strengthens your application security program by providing AI-powered penetration testing that complements SAST and SCA tools. While those tools catch code-level issues, APVISO discovers runtime vulnerabilities, business logic flaws, and complex attack chains that only emerge when the application is running.
