About Us
Who We Are
At Dover Microsystems, our mission is to immunize the world’s processors against all network-based attacks. CoreGuard®, our unique silicon IP with proprietary micropolicies, acts as a bodyguard to the host processor, monitoring every instruction executed to ensure it meets a set of security, safety, and privacy rules. With CoreGuard, a processor can actively stop entire classes of network-based attacks and prevent the exploitation of software vulnerabilities.
Dover’s CoreGuard silicon IP integrates with RISC architectures to protect against cyberattacks, flawed software, and safety violations. The technology originated as part of the DARPA CRASH program in 2010, was developed at Draper in 2015, and was spun out through Dover as a commercial entity in 2017.

History
While Dover Microsystems may have been founded in 2017, the core components of our CoreGuard technology have been in development since 2010. In fact, Dover’s revolutionary CoreGuard technology started as a DARPA CRASH program proposal submitted by Dover’s Founder and CEO, Jothy Rosenberg, and Dover’s Chief Scientist, Greg Sullivan, during their time with a leading multinational defense and aerospace company.
The clean-slate computer architecture optimized for security that Rosenberg and Sullivan had envisioned was accepted into the DARPA CRASH program and, over the next five years, was turned into a reality.
With their research having wrapped up at DARPA, Rosenberg, Sullivan, and their small team were invited by Draper President, Kaigham J. Gabriel—former DARPA Deputy Director—to develop the technology at Draper. A true breakthrough came when, in February 2016, Dover’s founding team demonstrated a processor-based security FPGA proof-of-concept that was immune to the Heartbleed cyberattack.
This proof-of-concept—which evolved into Dover’s CoreGuard silicon IP—made it clear that this technology had broad commercial and defense potential.
Founder & Executive Chairman Jothy Rosenberg and former Chief Scientist Greg Sullivan have their project accepted into the DARPA CRASH program.
Rosenberg, Sullivan, and their team conclude their research as the largest performer in the DARPA CRASH program and join Draper to develop the technology further.
Rosenberg and his team demonstrated the technology at Draper that would eventually become CoreGuard 1.0. The processor-based security FPGA proved immune to the Heartbleed flaw that affected two-thirds of the Internet.
While developing at Draper, the founding team lands its first commercial customer, NXP Semiconductors.
Rosenberg leaves Draper early to legally incorporate as Dover Microsystems, Inc. and commercialize the technology.
Dover spins out of Draper with an exclusive license agreement and opens its doors with a founding team of nine.
Dover announces its flagship, silicon IP cybersecurity solution, called CoreGuard.
The Dover team commercializes CoreGuard 1.0. Working with commercial clients, the Dover team quickly concludes that the CoreGuard 1.0 is too large and too slow to make it commercially viable on a large scale.
The Dover team completely rewrites CoreGuard to break free from the initial design and open up the commercial market. The new design is 85% smaller and designed for the first time to operate at full processor speed to enable the first true real-time (instruction speed) solution.

As a serial entrepreneur, Dover Microsystems is the 9th tech startup that Jothy has founded and/or run since 1988. Prior ventures include MasPar, Novasoft, Webspective, GeoTrust, Service Integrity, Ambric, Mogility, and Aguru; two of these companies sold for over $100M. Earlier in his career, Jothy ran Borland’s Languages division where he managed development of languages including Delphi, C++, and JBuilder. He earned his BA in Mathematics from Kalamazoo College and his PhD in Computer Science from Duke University (where he also had his first career as a professor of computer science for five years).
Jothy has written three technical books, but his pride and joy is his memoir, Who Says I Can’t; it tells his inspiring story of using extreme sports to regain self-esteem after being knocked flat as a teenager by a cancer that first claimed one of his legs and later one of his lungs. Bearing the same name as his memoir, Jothy founded and runs The Who Says I Can’t Foundation, a non-profit organization with a mission to help disabled individuals get back into life by getting back into sports. He also created and hosts the Who Says I Can’t TV series on YouTube, where he shares courageous stories of men and women who against all odds have used sports to rebuild themselves and their lives.
Jothy is a regular speaker at corporate events, universities, conferences, medical centers, schools, and clubs. Make sure to catch his Who Says I Can’t TEDx talk.
In his spare time (what spare time?), Jothy enjoys skiing, swimming, cycling, writing (currently a children’s book and his first novel), and playing with his Golden Retriever. He loves spending time with his family and recently welcomed his fourth grandchild.
