How to choose an IT governance and compliance partner
IT governance and compliance buying has tilted heavily toward regulatory readiness. NIS2 in the EU, DORA for EU financial entities, PCI DSS 4.0, the SEC cyber disclosure rules in the US, and ongoing state-level privacy regimes have all added formal documentation, attestation, and incident-disclosure obligations within the past 18 months. The right partner combines audit credibility with practical operating model design rather than producing a control library and disappearing.
Three procurement archetypes recur. Big Four firms (KPMG, Deloitte, PwC, EY) lead on multi-framework programmes where the audit relationship, SOX integration, and board-level reporting matter most. Independent assessor firms (A-LIGN, Schellman, Coalfire, BSI, DNV) lead on SOC 2, ISO, FedRAMP, HITRUST, and PCI assessments where independence from advisory work is a hard requirement; these firms cannot also provide the implementation. Specialist advisory firms (Protiviti, RSM, NCC Group, Control Risks, IT Governance Ltd) lead on ISO 27001 build, internal audit, and IT controls remediation where Big Four day rates exceed budget but methodological rigour is still required.

Frequently Asked Questions
How much does ISO 27001 certification cost?
A first-time ISO 27001:2022 certification programme for a 200-2,000 employee organisation typically runs $80k-$300k in advisory fees (gap analysis, ISMS build, internal audit) plus $25k-$80k in certification body audit fees split across stage 1, stage 2, and surveillance audits in years two and three. Larger multi-entity scopes scale roughly linearly with site count.
Big Four or specialist assessor?
For SOC 2, ISO 27001, FedRAMP, PCI, and HITRUST assessments, specialist independent assessors (A-LIGN, Schellman, Coalfire, BSI, DNV) typically deliver equivalent attestation quality at 30-50% lower cost than Big Four with materially faster turnaround. Big Four firms are the right answer where the engagement is integrated with statutory audit, where global multi-jurisdiction scope dominates, or where board-level credibility with regulators is a decision factor.
How should we approach DORA and NIS2?
DORA (in force January 2025 for EU financial entities) and NIS2 (transposed across EU member states with national variations) both demand documented governance, third-party risk management, incident reporting, and operational resilience testing. Treat them as governance and process programmes first and technology programmes second. Most failures in initial inspections come from missing or inconsistent third-party register data and from incident-response runbooks that have never been exercised.
Can we automate evidence collection?
Yes, and you should. Compliance automation platforms (Vanta, Drata, Secureframe, Sprinto for SOC 2 / ISO; LogicGate, OneTrust, ServiceNow IRM for enterprise) now collect 40-80% of routine control evidence automatically. They reduce audit prep effort materially but do not replace the operating model and risk-decision work that defines a credible programme. Buy automation only after you have a working ISMS or control framework.
What contract structure works for compliance partner work?
Fixed-price by phase (gap, build, internal audit, certification readiness) for compliance build engagements. Hourly capped fees with independent assessor firms for audit. Avoid bundling advisory and audit in the same firm where audit independence rules apply (SOC 2, ISO, PCI). Always require knowledge transfer, ISMS documentation handover, and evidence-collection runbooks that allow the client team to maintain certification with minimal partner dependency.
