The professional services ecosystem that governs every CNI procurement, M&A, and regulatory engagement.
In March 2026, the professional services sector has moved from "Support Function" to "Sovereign Enabler." Every CNI procurement, NSI Act notification, and regulatory compliance programme runs through a professional services supply chain - legal, advisory, accounting, and technical consulting. The Procurement Act 2023, in force since 24 February 2025, imposes a mandatory compliance architecture on all professional services firms advising public sector clients (its 1 April 2026 milestone extended registration to below-threshold suppliers). The Industrial Strategy explicitly identifies professional services as a foundational sector providing critical inputs to growth-driving sectors. Direct Intelligence provides the decision architecture to navigate this complex, multi-dimensional compliance environment.
