We assisted in implementing a Software Development Life Cycle (SDLC) as an integral component of a new product platform for a prominent medical device manufacturer. This encompassed conducting threat and risk analyses and enforcing Windows hardening measures such as firewall optimization, user management enhancement, chat reduction, DeviceGuard, and AppLocker. Additionally, we ensured adherence to regulatory measures, including Department of Defense (DoD) compliance, managed incidents and vulnerabilities through regular security updates, and developed comprehensive security documentation including security white papers, administration guides, and MDS2 forms.
