Sitehop is a technology company.
Sitehop develops ultra-low latency encryption solutions, leveraging FPGA-powered, quantum-ready technology for data-in-motion. Its products achieve sub-microsecond latency, enabling instant, proactive protection for network traffic. This engineering approach provides faster, energy-efficient, and robust alternatives to traditional encryption, integrating security seamlessly into high-performance networks.
Melissa Chambers co-founded Sitehop, incorporated in September 2021. The company emerged from the belief that businesses should not compromise security for speed or sustainability. This insight drove encryption solutions engineered for a quantum-ready future, offering proactive defense against evolving cyber threats, rather than reactive mitigation.
Sitehop’s technology serves critical sectors like telecommunications, data centers, and financial services, where rapid, secure data transfer is paramount. The company envisions a future where organizations operate confidently, their sensitive information protected at modern business speeds. Sitehop aims to ensure security empowers innovation, making it an indispensable asset.

Sitehop is a UK-based cybersecurity technology company founded in 2021 that builds FPGA-powered, quantum-ready encryption hardware solutions for securing data in motion across high-performance networks.[1][3][4][5][6] Its flagship SAFE Series products, such as the SAFEblade 1100 Enterprise, deliver ultra-low latency (sub-microsecond, 10,000x faster than software alternatives), 200Gbps full duplex throughput, crypto-agility for post-quantum threats, and 10x lower power consumption, solving the trade-offs between security, speed, and efficiency in legacy software-based encryption.[2][4][5] Sitehop serves telecom networks, critical infrastructure, financial services, data centers, enterprise technology, and government sectors, enabling scalable, multi-tenant encryption that integrates with SD-WAN, Zero Trust, and cloud environments while minimizing attack surfaces through hardware-enforced isolation.[3][4][5] With $7.52M raised in seed funding (latest round $6.31M two months ago), the company shows strong early momentum as a seed-stage startup based in Sheffield, England, with about 12 employees.[1][6]
Sitehop was founded in 2021 in Sheffield, United Kingdom, as company number 13602589, emerging from the need to address rising cybersecurity threats from AI, quantum computing, and software vulnerabilities in cloud and telecom networks.[1][3][6] While specific founders are not detailed in available sources, the company was born from a vision to engineer hardware-based encryption that anticipates quantum-era challenges rather than reacting to them, leveraging proprietary programmable FPGA (Field-Programmable Gate Array) technology for real-time, unbreakable security.[3][4][5] Early traction came through development of the SAFE Series, which gained investor attention—raising $7.52M in seed VC funding, including a $6.31M round just two months ago—validating its hardware-first approach amid growing demands for low-latency, energy-efficient network protection.[1]
Sitehop rides the convergence of AI-driven attacks, quantum computing risks, and explosive growth in 5G/cloud networks, where legacy software encryption fails due to high latency, power demands, and vulnerability to "harvest now, decrypt later" threats.[3][4][5] Timing is critical as quantum breakthroughs loom and regulations push for PQC adoption, positioning Sitehop's hardware solutions to secure data-in-motion for telecom fiber/5G, financial transactions, government systems, and critical infrastructure amid rising cyber incidents.[1][4] Market forces like energy constraints in data centers and the shift to Zero Trust architectures favor its low-power, scalable model, influencing the ecosystem by enabling faster, greener secure networks and challenging software giants with a "security without compromise" paradigm.[2][5]
Sitehop is poised to scale its SAFE Series globally, targeting expansions in 5G rollouts, HPC workloads, and quantum transition mandates, with recent funding fueling product iterations and partnerships in telecom/finance.[1][4] Trends like AI-enhanced threats and net-zero mandates will amplify demand for its FPGA edge, potentially evolving it into a key enabler for quantum-secure infrastructure. As networks demand instantaneous, sustainable protection, Sitehop's hardware innovation could redefine encryption standards, keeping businesses "engineered for speed and built for the future."[3]
Sitehop has raised $16.0M across 2 funding rounds. Most recently, it raised $10.0M Series A in October 2025.
