This page lists 10 it compliance companies providers that work with United States clients. We look at delivery track record, whether the team overlaps with US time zones, how they scope and price work, and whether they can sign standard US contracts including an MSA, SOW, NDA and mutual indemnity.
Firms currently featured include Coalfire, Schellman, A-LIGN, and BDO Digital.
Delivery footprints on this list span Westminster, CO, USA, Tampa, FL, USA, Chicago, IL, USA, and Nashville, TN, USA, so you can choose between onshore US delivery, nearshore teams with 3–5 hours of overlap, and offshore teams priced for volume work.
US buyers usually see three engagement models for it compliance companies: fixed-scope projects, time and materials with a monthly cap, and a dedicated team retainer. Onshore US consultancies typically bill $155–$250 per hour, nearshore partners in Latin America $55–$95, and offshore teams $25–$55.
Ask for a rate card by role, not a blended rate — a blended number hides how much of the work is done by junior staff. For fixed-bid work, insist on a written change-order process, and for retainers, confirm the notice period and any minimum monthly hours.
Watch the total cost of ownership: discovery workshops, knowledge transfer, post-launch support, and the cost of taking the work back in house at the end.
Before you sign, confirm the provider carries professional liability (E&O) and cyber insurance with US-acceptable limits, and that the MSA clearly assigns IP ownership of all deliverables to you on payment.
If the engagement touches regulated data, get the compliance posture in writing: SOC 2 Type II for the provider's own systems, HIPAA with a signed BAA for health data, CCPA/CPRA handling for California consumer data, GLBA for financial services, and background-check policies for anyone with production access.
Also nail down worker classification and subcontracting — many US buyers require written approval before any part of the work is passed to a third party.
Run the same questions past two or three firms from this list and compare the answers side by side — the differences are usually more revealing than the proposals.
