GreyCastle Security and DeepSeas Partner to Offer a Comprehensive Cyber Defense Program for Mid-Market Clients    

San Diego, CA and Troy, NY – May 10, 2023 — Threat actors are collaborating to attack. It only makes sense for defenders to collaborate in return. Today, DeepSeas LLC and GreyCastle Security LLC announced a strategic partnership. GreyCa­­­stle has chosen DeepSeas as its provider of managed detection and response (MDR) services. DeepSeas technical controls combined with GreyCastle advisory and risk consultation will ensure clients can prioritize investments and measure progress against cyber frameworks and controls. 

“We’re a trusted leader in cyber security strategy and preparedness, and we embrace the fact that our customers expect us to bring forth effective solutions that best suit their needs, now and into the future,” said Dan Kalil, CEO of GreyCastle Security. “To that point, we’ve worked closely with DeepSeas for over a year, and now is the right time to launch this partnership. DeepSeas MDR+ aligns well with our offerings and we’re proud to be partnered with them.”

Together, this partnership will serve as a force multiplier to always be one step ahead of attackers in the cyber kill chain. When threat attackers come to an organization defended by DeepSeas and GreyCastle Security, they are more likely to move on to a lesser defended target.  

“DeepSeas Managed Detection and Response solution, which we call MDR+, relies on an initial line of high fidelity, interactive threat detection and response capabilities, with the primary detection response tool being endpoint detection and response,” said Mike Johnson, VP of Partners & Alliances at DeepSeas.
