Trusted by enterprise, government and the NHS
Winfrasoft builds commercially supported infrastructure security and authentication tools for enterprises, government and the NHS, solving the gaps that platform vendors leave open. Our products protect millions of users across twenty-seven countries.
Commercially supported tools for the security problems that enterprise platforms don't solve natively. Fully engineered, fully tested, file-based licensing: not open-source best-effort, not unmaintained community projects.
Your IIS logs record your load balancer's address: not the real visitor's. X-Forwarded-For for IIS fixes that completely: it reads the X-Forwarded-For header and writes the genuine client IP directly into the standard IIS c-ip field. No application changes, no custom log formats; existing SIEM integrations, log analysers and compliance reports keep working unchanged. Commercially supported, with full anti-spoofing Proxy Trust List, built for Windows Server 2016–2025.

Winfrasoft was founded in 2005 to solve a specific class of enterprise security problem: making complex identity and access infrastructure workable for the organisations that actually have to run it. Two decades on, that mission is unchanged, but the technology landscape has shifted several times, and so have we.
The company earned its reputation building authentication and infrastructure security products for the Microsoft platform — first supporting Forefront TMG, UAG, and ISA Server estates, then extending into pattern-based multi-factor authentication with Authlogics PINgrid, which was spun out in 2015. Authlogics was acquired by Intercede Group plc in 2023.
Today, Winfrasoft is a focused independent software vendor developing the next generation of identity and security products. Our customer base spans enterprises, government departments, and the NHS across twenty-seven countries, with an end-user reach in the millions.
