Top IT Consulting and Systems Integration (SI) Companies

Specialist IT consulting and SI covers integration and advisory work outside platform categories such as ERP, CRM, cloud or BI: security consulting and penetration testing, independent software testing, integration of niche systems such as HR, payroll or point of sale, architecture reviews and technology due diligence. A business comes here when two systems must talk and no vendor owns the problem, when an auditor or customer demands an independent assessment, or when a technology decision needs outside advice.

The firms here differ widely, so compare them on the system pairs and assessment types they have delivered, look for reviews that describe a project like yours, and match the minimum project to an assessment or a full integration.
