Compare 60 public sector IT consultancies delivering digital government, legacy modernisation, cloud migration, and citizen-service programmes for federal, state, local, and devolved administration buyers. Listings include framework presence (GSA MAS, G-Cloud 14, FedRAMP, ITAR clearance counts, cleared headcount where disclosable), vertical focus, and verified buyer ratings from public sector procurement. The market remains dominated by cleared-headcount supply and framework access; partner choice is heavily constrained by contract vehicle. Use this directory to shortlist public sector IT partners by framework, security clearance posture, and citizen-service archetype. No partner pays for placement on this directory.
Public sector IT engagements typically split into four workstreams. Citizen-service modernisation, where partners replace legacy front-ends and case management systems with cloud-based digital services, often under user-centred design standards (UK GDS, US Digital Services). Legacy core modernisation, the larger and harder workstream, where partners migrate decades-old benefits, tax, health, justice, or licensing systems off mainframes and AS/400 estates. Cloud and FedRAMP/IL5 programmes, which dominate spending for federal buyers in particular. Workforce modernisation, including HCM and ERP for government, typically on Workday Government Cloud, Oracle Fusion Federal, or SAP Public Cloud for government.
Three procurement archetypes recur. Federal services arms with deep cleared headcount (Accenture Federal, Deloitte GPS, Leidos, Booz Allen, SAIC, GDIT, IBM Federal, CGI Federal) lead US federal delivery; framework presence and cleared bench size, more than technical depth, drive selection. UK and EMEA digital specialists (Kainos, Made Tech, Capgemini Government, KPMG Public Sector) lead UK central government and EU member-state programmes through G-Cloud and equivalent frameworks. Global SIs and India-heritage SIs compete on multi-year managed engagements with on-shore cleared overlay teams. Friction point: federal programme overruns remain endemic. The GAO's high-risk list has consistently flagged IT acquisitions, and many flagship programmes ship years late and 50-200% over original cost; partner track record on schedule recovery matters more than slideware.
