CyberHive

CyberHive is a UK cybersecurity vendor built around a specific, narrow problem: securing communications for organizations that operate in bandwidth-constrained, high-latency, or physically hostile environments — defence platforms, maritime vessels, aerospace systems, and emergency services networks — where conventional VPN and perimeter architectures either don’t fit the connectivity profile or don’t meet the threat model. Its flagship product, CyberHive Connect, is a software-defined, zero-trust mesh network that authenticates and encrypts every connection point-to-point rather than relying on a hub-and-spoke VPN concentrator, and it layers in post-quantum cryptography so that traffic captured today can’t be decrypted retroactively once quantum computing matures.

The product family spans Connect Core (the base zero-trust mesh), Connect IoT (extending the same identity-and-encryption model to constrained IoT and OT devices), and Connect 365, alongside a separate CASB offering (Gatekeeper) for Microsoft 365 environments and a Trusted Cloud hosting option for sensitive workloads. The common thread is lightweight deployment: CyberHive markets Connect as materially cheaper and simpler to administer than legacy VPN infrastructure, particularly for organizations managing large numbers of remote or intermittently-connected endpoints.

CyberHive is a small company — roughly 15 employees, per its own site — operating in a defence-adjacent niche rather than broad enterprise IT. It has raised a modest amount of institutional capital (a 2021 Series A led by Mercia and 24Haymarket) and in January 2025 announced a partnership with UAE-based Meerana to co-develop zero-trust offerings for Gulf-region customers, suggesting an effort to extend beyond its UK defence base. The company has not published named enterprise case studies or independent third-party evaluations of Connect’s security claims, so most of what’s verifiable about its effectiveness comes from the architecture itself (point-to-point mutual authentication, post-quantum key exchange) rather than field-tested outcomes.
