CyberHive is a UK-based cybersecurity company that designs and delivers secure communication solutions for organizations operating in bandwidth-constrained, high-risk, and mission-critical environments. Its primary customers include defence, maritime, aerospace, emergency services, and hybrid enterprises. The company was founded in 2018 as a specialist cybersecurity consultancy focused on government and regulated sectors. It transitioned toward product-led development, launching its flagship platform, Connect, in 2023. The Connect product family now consists of three offerings: Connect Core, Connect IoT, and Connect 365, each tailored to different operational needs within critical sectors. CyberHive's solutions are built on a zero-trust architecture, meaning they operate without open ports or assumed trust, and are designed for deployment in environments where traditional cybersecurity infrastructure is impractical or unavailable. A distinguishing technical characteristic of their products is the integration of post-quantum cryptography, intended to protect communications against future threats posed by quantum computing advances. The company emphasizes lightweight deployment and resilience at the edge, targeting scenarios where connectivity is limited and failure is not an acceptable outcome. CyberHive has received over £1 million in investment and participates in EU-funded research projects, including a €4.9 million EU project announced in its insights content. The team is composed of developers, DevOps engineers, and operations staff, led by a founder-CTO and a CEO.
