Jothy Rosenberg Seeks Strategic Partner for Dover Microsystems’ 17-Patent Hardware Cybersecurity Technology

Boston, Massachusetts, September 22nd, 2026, FinanceWire

Jothy Rosenberg is seeking a strategic buyer, investor, or licensing partner to advance Dover Microsystems’ processor-level cybersecurity technology for future computing systems.

Jothy Rosenberg, founder of Dover Microsystems, is seeking a strategic buyer, investor, and licensing partner to take the company’s hardware cybersecurity technology into its next stage of development and commercialization. Dover’s technology is designed to add security enforcement tightly coupled with an executing processor, giving computing systems a hardware-based mechanism for evaluating instructions for correctness as they execute.

Rosenberg’s decision comes as processors support increasingly complex applications across artificial intelligence, connected devices, industrial systems, defense technologies, and other computing environments. Modern software stacks can contain tens of millions of lines of code, creating extensive opportunities for vulnerabilities to emerge. For Rosenberg, that points to a security question at the processor level. Software can help protect software, while the processor itself can also participate in enforcing security rules.

Dover’s technology, CoreGuard, originated through DARPA’s Clean-Slate Design of Resilient, Adaptive, Secure Hosts (CRASH) program in 2010 under the prime contractor BAE Systems, where Rosenberg was the co-PI. CRASH was an effort to investigate new computer architectures that could address vulnerabilities through changes spanning design, implementation, and execution. The technology was subsequently commercialized by Rosenberg as Dover Microsystems in 2017. In 2018, a semiconductor company engaged Dover to introduce CoreGuard into their future embedded platforms.

CoreGuard operates as silicon intellectual property alongside a host processor. Its programmable “micropolicies” establish rules governing processor activity, with the system monitoring instructions as they move through execution. When activity conflicts with an applicable policy, the technology can prevent that instruction from executing and provide information to the surrounding system. The architecture has been integrated with several ARM processor types and numerous RISC-V implementations, and can be deployed on both application-specific integrated circuits (ASICs) and field-programmable gate arrays (FPGAs), supporting applications ranging from high-volume fabricated silicon to specialized, lower-volume systems.

A key aspect of the approach is that protection occurs in real time, at the speed of the processor itself. Rather than detecting a compromise after an attack has occurred, the technology can stop a policy-violating instruction on its first occurrence, before it can cause damage. The processor is then notified and can respond according to the requirements of the system, including switching to an alternate application or operating mode to maintain a critical function or mission.

The design is intended to address software-exploitation techniques, including attacks that attempt to use software vulnerabilities to execute unauthorized code, such as buffer overflow. “Processors execute instructions at extremely high speed, yet the traditional processor has limited information about whether an instruction represents legitimate activity,” Rosenberg states. “Our work gives the processor a role in enforcing rules about what software is permitted to do. That creates a security boundary at the point where instructions become execution.”

The technology has been developed over more than a decade, with Dover reporting a portfolio of 17 issued utility patents covering interconnected elements of its hardware security architecture. That development has included work with semiconductor and embedded-computing organizations, as well as applications involving the defense sector. Dover has also licensed CoreGuard technology and associated patents to a mid-sized U.S. defense contractor developing a secure processor for its defense customers, providing a commercial application of the technology in a demanding security environment.

The timing of the strategic search also reflects changes in the computing environment. According to IBM’s 2026 Cost of a Data Breach Report, one in four malicious breaches studied were AI-enabled, while breaches involving AI averaged approximately $6 million in cost. AI systems add another dimension because the software supporting models, applications, and surrounding infrastructure can become part of the security equation.

Rosenberg’s interest in finding a partner is tied to expanding the technology’s reach. After years of developing Dover, he is seeking an organization with the engineering resources, semiconductor relationships, manufacturing connections, distribution capabilities, or technology portfolio needed to bring processor-level protection into additional computing platforms.

“I want this technology to get into the world and have the opportunity to be used where processor security matters,” Rosenberg remarks. “I have spent more than a decade helping develop the underlying technology and intellectual property. The next chapter requires an organization that can take what has been built and integrate it into a broader range of processors and systems, giving the partner a competitive advantage.”

Potential applications include embedded processors, artificial intelligence infrastructure, defense systems, IoT, and edge computing devices where software execution can have operational consequences. The ability to operate across ARM and RISC-V architectures and on both ASIC and FPGA platforms also allows the technology to be considered across different processor designs and deployment environments.

Rosenberg is now seeking strategic discussions with qualified companies interested in acquiring, licensing, investing in, or commercializing Dover’s technology and intellectual property. The objective is to identify a partner capable of supporting the next phase of deployment for the processor-level security architecture developed through Dover Microsystems.
