Case Study: Siemens Healthineers achieves faster, more secure application development with Checkmarx SAST

Siemens Healthineers Accelerates Application Development Securely With Checkmarx

Siemens Healthineers, a global medical‑technology leader, needed to ensure the safety and security of software that runs and supports its connected medical devices. Relying mainly on late-stage penetration testing and inadequate static code tools left code‑related vulnerabilities undiscovered until late in the SDLC, creating regulatory and patient‑safety risks and slowing remediation.

Siemens implemented Checkmarx Static Application Security Testing (SAST) on‑premises to shift security left, enabling fast, accurate full and incremental scans, prioritized findings, and “best fix location” guidance for developers. As a result, vulnerabilities are caught much earlier and fixed faster—over 250 applications and more than 149 million lines of code are scanned weekly, with over 90% of projects scanned each week—improving code quality and reducing pressure on pen testing.
