What Microsec does

Microsec is a UK-based custom software development and IT services firm founded in 1979, headquartered in Havant with a second UK office in Plymouth and group-affiliated delivery centres in Warsaw (Nexio Management), Sibiu (Nexio Romania), and Dhaka. The company employs 251–500 people and accesses approximately 500 additional IT specialists through its Nexio Management partnership, giving the wider group access to roughly 500 engineers across Europe and South Asia. Microsec's core offering is bespoke software delivery: custom mobile and web applications, enterprise software, legacy system maintenance and modernisation, project recovery, UX design, and website development, executed on a Microsoft .NET-centric technology stack (C#, VB.NET, ASP.NET, SQL Server, Xamarin) with supplementary Java, Perl, and Uniface capabilities.

The company's revenue model is professional services-led, with quote-based, multi-year project engagements sold through a consultative direct-sales motion that begins with a free 30-minute consultation and discovery workshops. Customers are predominantly large enterprises and regulated organisations, including Network Rail, Orange, Atos, Bank of Scotland, T-Mobile, GlaxoSmithKline, WPA, Pall Corporation, the Welsh Government, AXA Poland, and Optima Health, with engagements spanning healthcare, rail infrastructure, insurance, telecommunications, banking, and pharmaceuticals. Notable deliverables include the GSM-R Radio Training Simulator for Network Rail, the QPData filter-management system for Pall Corporation, and the WPA Health App (260,000+ logins and 25,000+ claims processed since November 2019).

Microsec is a privately held UK limited company (Microsec Ltd) that is part of a wider creative development group under common ownership and management alongside Nexio Management, Nexio Romania, and Elixel. It is one of the first UK holders of BS EN ISO 9001 and TickITPlus accreditation, holds Xamarin Premier Consulting Partner status with Microsoft, and operates security practices aligned with OWASP, CHECK, and CREST standards. There is no disclosed funding, no public listing, and no institutional investor presence in the available data.
