Sitehop Secures £5 Million Seed Funding to Advance Hardware Encryption
In Focus
- Sitehop quantum cybersecurity funding: UK startup raises £5 million seed round to scale its encryption hardware
- Flagship hardware product, SAFEblade 1100, offers sub-900 nanoseconds latency and supports over 4,000 secure tunnels
- Investment will drive international expansion: hiring in US, Brazil, India; growing operations at Yorkshire HQ
- Technology built for post-quantum cryptography readiness: hardware-enforced encryption aimed at telco, cloud, finance, government sectors
Sitehop, a Sheffield-based cybersecurity startup, has raised £5 million in a seed funding round to further develop its hardware-based encryption tools and push forward its Sitehop quantum cybersecurity funding strategy. According to its press release and public reporting, the round was co-led by Amadeus Capital Partners and Manta Ray Ventures, with support from Mercia Ventures, the Northern Powerhouse Investment Fund, and several angel investors.
Hardware-Enforced Encryption Meets Post-Quantum Demands
Sitehop’s core offering addresses a critical challenge; existing software encryption solutions often slow down communication networks, increasing latency and energy consumption. The company claims its SAFEblade 1100 product supports over 4,000 secure tunnels concurrently and offers encryption/decryption latency of less than 900 nanoseconds at 100 Gbps throughput.
Key features and contexts include:
- Hardware enforcement via FPGA-based boards rather than purely software encryption. This reduces latency and lowers the load on server infrastructure.
- Energy efficiency: Sitehop claims its solutions use significantly less power than traditional software encryption. They are quantum-ready, meaning designed with future threats from quantum computing in mind.
The funding will support Sitehop’s product roadmap that spans securing “all types of data-in-motion” and building out its SAFE series, which covers scalable, high-speed, low latency hardware encryption across telecom, cloud, finance, government and other critical infrastructure sectors.

Expansion, Ecosystem, and Market Adoption
With the seed round secured, Sitehop is deploying capital toward geographic expansion and scaling its teams. Its plans include hiring sales, support and engineering staff in Brazil, the United States, India, as well as expanding operations at its Yorkshire headquarters. In other news, earlier this month, a hacking group threatened to leak billions of records stolen in a Salesforce cyber attack.
Sitehop also is securing traction in the market:
- Its SAFE Series encryption solutions are already deployed in carrier networks across several countries.
- In partnership with BT, Sitehop is involved in quantum-safe R&D, including proof-of-concept work in BT’s Gemini lab. The aim is to test quantum-ready, FPGA-powered encryption hardware with very low latency and low power consumption to protect data in motion in live-network-like conditions.
“We Aim to Get Sitehop’s Products Into the Backbone …”
Melissa Chambers, CEO of Sitehop, noted, “This investment allows us to expand our global reach, with sales and support engineering staff in Brazil, the US, India, and grow our Yorkshire headquarters. We will be adding engineers and production workers and moving into a new Sheffield location. The investment will also enable Sitehop to pursue its technology roadmap – fleshing out the range of SAFE products securing all types of data-in-motion and developing parallel products using our world-class skillsets in cryptography and programmable hardware design,” as stated by Amadeus Capital.
Nick Kingsbury, Partner at Amadeus Capital Partners, said, “Sitehop is bringing a novel hardware-based approach to a fundamental challenge facing the providers of the essential network infrastructure underpinning our digital society. The flexibility and scalability of Sitehop’s data encryption technology makes it accessible to SMEs as well as large enterprises, meaning there need be no weak link in our defence against cyber criminality” according to UKTN.
Implications for Encryption, Security, and Quantum Risk Preparedness
Sitehop’s funding and progress underscore growing B2B demand for encryption solutions that do not compromise speed or operational performance. For business owners, industry specialists, and decision‐makers, the importance lies in choosing cybersecurity systems that are post-quantum cryptography-ready, energy-efficient, and able to support complex, high-volume network traffic without latency bottlenecks. Earlier this year, Google acquired Wiz for $32 billion.
The Sitehop quantum cybersecurity funding round marks a significant step toward hardware-first solutions in the encryption sector, especially as quantum computing edges closer to making current standards vulnerable. Organizations in sectors such as cloud, telecom, finance, and government will need to follow developments like Sitehop’s to avoid potential future risk exposure.
