Binary Defense

Binary Defense is a cybersecurity company headquartered in Stow, Ohio that provides managed detection and response and security operations services. The company was founded by Dave Kennedy after he identified a need for stronger monitoring, detection and response services for organizations without sufficient internal security resources. Binary Defense combines human security analysts with technology designed to monitor endpoint, network, cloud, identity and email environments. Its current platform, NightBeacon, uses AI-assisted investigation to reduce alert volume and prepare evidence for analyst review while maintaining an auditable record of actions. Customers can use the technology themselves through NightBeacon CMD or have Binary Defense operate the security operations function as a managed service. The company's services include 24/7 managed detection and response, proactive threat hunting and digital risk protection. Binary Defense emphasizes transparency, human oversight and compatibility with customers' existing security controls rather than forcing a single vendor technology stack. Its Open XDR approach can integrate data from multiple security products and provide centralized detection and response. The company serves organizations that need continuous security monitoring but may not have the resources to operate a full internal SOC. Binary Defense is particularly relevant to mid-market and enterprise buyers looking for a combination of managed security expertise, threat hunting and AI-assisted investigation.
