Assured Information Security Acquires GreyCastle Security

Assured Information Security, Inc. (AIS), based in Rome, NY, has purchased a majority interest in GreyCastle Security, LLC (GreyCastle), a Troy, NY based cyber security firm with additional offices in Rochester, NY. With this investment, AIS continues to expand its presence within the commercial space, and solidify its position as a leader in cyber and information security offerings. The synergy between the two companies and their offerings became apparent early on, and leaders of AIS and GreyCastle feel confident that this arrangement positions both companies for even greater success in the marketplace.


GreyCastle Security Co-founder, CEO, and President, Reg Harnish, and the rest of the GreyCastle staff will remain in place and continue leading operations. In deciding to secure outside investment, Harnish stated, “We have a strong culture that originates from a tight-knit team of skilled personnel. They know and embrace their roles in support of our company’s customer-centric vision, and as a team, strive to achieve that vision every day. AIS provides us with valuable operating capital needed to secure additional qualified talent, while also providing key administrative and technical resources that will allow us to focus on what we do best: provide our customers with the very best in cyber security services.”

AIS’ Mike Denz will serve as GreyCastle’s CFO, while Dan Kalil, also of AIS, will serve as the company’s Chief Strategy Officer (CSO) and Chairman of the Board. Kalil said, “GreyCastle is a company with a very strong upside, and it starts with their people and processes. Seeing how efficiently they operate, our focus is on manageable growth, and increasing the overall value of the organization.”

With this investment, AIS continues its strategic growth, having recently acquired Maryland-based firm Ross Technologies (RTGX). AIS is a cyber security firm founded and headquartered in Rome, NY, that maintains operating locations throughout the U.S. AIS provides government and commercial customers with industry leading cyber security capabilities and services such as research, development, consulting, testing, forensics, remediation, and training.
