Mark leads Senserva's vision of transforming reactive security management into proactive, automated protection. Working alongside the engineering team, he continues to drive innovation in security automation with the same passion that has defined his career.
Mark's professional journey began at Microsoft, where he was selected as one of the pioneering developers for the original Windows NT team, led by David Cutler. This foundational experience in building secure systems at scale shaped his understanding of enterprise security challenges.
His career trajectory then led him to establish Shavlik Technologies, a company focused on providing global security solutions for millions of servers and endpoints, including products like HfNetChk and MBSA. The innovative technology Mark created continues to secure millions of computers globally today, with many leading patching products built on the foundations he established. Today, Shavlik technology operates under a new name and as part of a different company, continuing its mission to secure millions of computers worldwide.
"Microsoft teamed with security software developer Shavlik Technologies LLC in St. Paul, Minn., to build the HFNetChk and Microsoft Personal Security Advisor (MBSA) tools. The tools are the first in a series of products from Microsoft aimed at helping users better secure their systems", noted Scott Culp, Microsoft security manager. Tim Rains, Chief Security Advisor of Microsoft's Worldwide Cybersecurity & Data Protection group, highlighted the impact: "MBSA scanned over 3 million computers each week."
After successfully building and selling Shavlik Technologies to VMware (where he collaborated with Paul Maritz and Raghu Raghuram), Mark recognized that the security landscape was evolving beyond traditional patch management. The rise of cloud computing and hybrid environments created new challenges around configuration drift and automated security posture management.
This insight led to the founding of Senserva, where Mark now focuses on solving modern security challenges in Microsoft environments. As a member of the Microsoft Intelligent Security Association (MISA), Senserva continues Mark's legacy of deep Microsoft ecosystem integration while addressing today's configuration management and security automation needs.
