WORK HISTORY
Founder & Chief Technology Officer @Cyberhive
Newbury, GB
Strategic and innovative thinker, effective communicator, and an expert in technological development.Spotting emerging technology trends and leading our expert team to make them a reality.I have lead the development of CyberHive Connect, an efficient encrypted zero-trust overlay network integrating multiple post-quantum resistant cryptographic algorithms.Connect includes current best-practice classical cryptography combined in a hybrid manner with NIST recommended post-quantum cryptography. This hybrid solution simplifies security accreditation as it meets current requirements for well-proven cryptography while bridging the gap to a future post-quantum world. As some of the NIST algorithms are relatively new, Connect uses multiple post-quantum algorithms to run its internal key derivation functions meaning that a weakness in one of the approved algorithms will not weaken the security of the system. Connect is deployable in a dynamic manner in existing infrastructure, allowing a gradual rollout and testing process that does not disrupt current work practices.It is simple to manage at scale through a distributed data plane combined with a centralised control plane that can be easily integrated with security policy, identity management and vulnerability monitoring systems.The current release of Connect provides enhanced security and privacy at multiple layers through:• post quantum encryption of both peer-to-peer and peer to server communication• native encryption of DNS traffic to prevent eavesdropping and spoofing attacks• automatic post-quantum encapsulation tunnels around classical TLS traffic• support for draft FIPS 203 to secure API and control-plane traffic• efficient cryptographic handshaking validated on geostationary satellite comms, speeding connections while reducing overheads to lower costs and resist the effects of packet loss.I have patents on distributed remote attestation of Trusted Computing beyond the initial trusted boot process.

ABOUT DAVID BLUNDELL
Critical networks should be invisible to adversaries.I founded CyberHive to address a specific challenge: how do you maintain secure, attribution-resistant communications in contested and bandwidth-constrained environments - where network signatures enable detection, geolocation, and targeting?CyberHive Connect is our answer: a post-quantum resistant Zero Trust Network Access solution engineered for defence, government, and critical national infrastructure. Unlike conventional VPN and enterprise ZTNA products, Connect eliminates trackable network signatures in transit, masks IP attribution at both ends with no listening ports, and maintains session continuity across degraded, disrupted, and denied networks.Our technology is deployed with UK Central Government customers, was selected for a HMGCC Co-Creation challenge, and secures C2 communications for maritime autonomous vessel operations. We work across uncrewed systems, tactical networks, satellite communications, and environments where network-layer exposure creates survivability and force-protection risk.Technical focus:* Post-quantum cryptography (hybrid ML-KEM + classical), aligned with government migration timelines* Secure overlay networks with native multicast support* Distributed cryptographic attestation (Granted UK and US patents)* Resilient operation over any IP-bearing transportI lead a technical team building production-grade, secure-by-design software for organisations that cannot afford to wait for the quantum threat to materialise. My work includes publications on secure cloud architecture and privacy frameworks, and participation in European Space Agency and Horizon Europe research programmes.If you\'re addressing post-quantum migration, Zero Trust adoption, or secure communications for contested environments, I\'d welcome a conversation.
