Compliance Framework Comparison

Compliance frameworks fall into three categories based on their origin and intent:

• Customer-driven: Frameworks customers ask about (SOC 2, ISO 27001, HITRUST). Voluntary attestations that signal security maturity.
• Regulator-driven: Frameworks required by regulators (HIPAA, GLBA, PCI DSS, FedRAMP, CMMC). Mandatory for organizations meeting specific criteria.
• Sector-specific: Frameworks specific to industries (HITRUST for healthcare, PCI DSS for payments, FedRAMP for government cloud, CMMC for defense)

Most organizations need at least one customer-driven framework (typically SOC 2 or ISO 27001) and any sector-specific frameworks that apply to their business. Pure regulator-driven frameworks apply to specific industries: healthcare, finance, government, defense.

Reference the frameworks hub for detailed information on each framework.

The most common comparison: SOC 2 vs ISO 27001. Both are voluntary, customer-driven frameworks. Differences:

• Geographic preference: SOC 2 dominates US market. ISO 27001 is preferred internationally, especially Europe and Asia.
• Structure: SOC 2 is principles-based with auditor judgment. ISO 27001 is prescriptive with defined controls and clauses.
• Output: SOC 2 produces a detailed report (40-100 pages) for customer review. ISO 27001 produces a 1-2 page certificate plus audit summary.
• Audit cycle: SOC 2 Type II is annual, covers 12 months. ISO 27001 has surveillance audits in years 2 and 3, recertification in year 4.
• Cost: Similar order of magnitude. SOC 2 typically $30K-$80K annually. ISO 27001 $30K-$80K with three-year cycle.

Many enterprise SaaS companies pursue both. Customer questionnaires ask for both. The control overlap is high (60-70%), so the marginal cost of doing both is lower than the cost of doing each separately.

Mandatory frameworks based on industry and customer:

• HIPAA: Healthcare data. Covered entities and business associates handling PHI. Direct OCR enforcement with significant fines.
• PCI DSS: Payment card data. Anyone storing, processing, or transmitting cardholder data. Enforced by card brands through acquiring banks.
• GLBA: Financial services. Banks, securities firms, insurance companies. FTC and federal banking regulators enforce.
• FedRAMP: Cloud services for federal government customers. Required for any cloud service used by federal agencies.
• CMMC: DoD contractors handling CUI. Required for relevant DFARS contracts. C3PAO assessment.
• NYDFS Cybersecurity Regulation: Financial services in New York state. State enforcement with mandatory cybersecurity program.
• India DPDPA: Personal data of Indian residents. Data Protection Board enforcement.

These frameworks are not optional. If you fall in scope, you must comply. The consequence of non-compliance ranges from monetary penalties to loss of customer relationships to criminal liability.

Several emerging frameworks address AI and data protection:

• EU AI Act: Comprehensive AI regulation in EU. Tiered obligations based on risk level. Enforcement begins phased in 2025-2026.
• ISO 42001: AI management system standard. Voluntary but expected to become harmonized standard for EU AI Act.
• NIST AI RMF: US voluntary AI risk management framework. Increasingly referenced by US federal agencies.
• GDPR: EU privacy regulation. Mandatory for organizations processing EU resident data.
• India DPDPA: India personal data protection law. Enforcement phasing in.
• State privacy laws (US): California (CCPA/CPRA), Virginia (VCDPA), Colorado (CPA), and 15+ other states with active privacy laws.

Track AI and privacy frameworks even if not currently in scope. The trajectory is toward more regulation, not less. Build governance now to be ready when frameworks become mandatory or customer-required.

A practical decision framework:

1. Mandatory frameworks first: Identify regulatory frameworks that apply based on your industry, customers, and data types. These are non-negotiable.
2. Customer-driven frameworks second: Look at your top 20 customers and prospects. What do they ask for? SOC 2 dominates US enterprise. ISO 27001 dominates international.
3. Sector-specific frameworks third: HITRUST for healthcare, PCI DSS for payments, FedRAMP for government, CMMC for defense. Add if relevant to your sector.
4. Emerging frameworks last: ISO 42001 if AI is core to your offering, GDPR if EU presence, US state privacy laws if consumer-facing.

Most SaaS companies end up with 2-4 frameworks active simultaneously. The cross-framework mapping pattern (single control mapped to multiple frameworks) is the operational pattern that makes this manageable.
