Replify

Replify is a Belfast, Northern Ireland-based software company that has been pioneering WAN optimisation and application acceleration for over 15 years. Founded as the first WAN optimisation company to market with a software-only product, Replify has evolved into a trusted provider of acceleration technology deployed across fibre, MPLS, LTE (3G/4G/5G), broadband, and satellite/Starlink connections worldwide.

The Replify Accelerator employs a four-stage Intelligent Caching Engine (ICE) that combines protocol optimisation, block-level cross-protocol deduplication, lossless compression, and TCP optimisation to dramatically reduce data volumes and improve application responsiveness. The product can be deployed standalone, white-labelled, or deeply integrated via OEM agreements into SD-WAN, SASE, and ZTNA platforms. Replify has successfully partnered with vendors including Open Systems AG to embed acceleration directly into their networking products.

Replify's product suite addresses four core solution areas: Acceleration for Remote Workers via the Mobile Client Accelerator on Windows, macOS, Linux, and Android devices; Cloud Acceleration for optimising traffic to AWS, Azure, GCP, and other cloud platforms; SD-WAN Acceleration as a Virtual Network Function (VNF) integrated into existing SD-WAN solutions; and ZTNA Acceleration that works transparently alongside zero-trust network access gateways such as Appgate SDP.

Major deployments include Mowi (the world's largest farm-raised salmon producer) with 14,500 users across 25 countries, Primark with 200 retail stores across Europe, the C2K education project covering 900 schools and 30,000 PCs in Northern Ireland, and approximately 1,000 private jets with satellite-optimised connections. Replify is also deployed extensively in maritime, construction, hospitality, and government sectors.
