Sitehop develops the SAFEseries encryption system, which performs encryption in dedicated hardware rather than software, delivering ultra-low latency, quantum-resilient security and up to 90% lower energy use than conventional systems. Target sectors are telecoms, critical infrastructure, financial services, data centres, enterprise and government. Founded in Sheffield by CEO Melissa Chambers and CTO Ben Harper, Sitehop works with BT, completed a proof-of-concept trial at BT's Gemini test facility, and is live with a tier-one carrier across five countries.
