Compliance frameworks explained.
SOC 2, ISO 27001, PCI DSS, NIST CSF. They sound complicated, but they do not have to be. Here is what each one actually means for your business.
At a glance.
| Framework | Best For | Required When | Timeline | Cost Without Tools |
|---|---|---|---|---|
| SOC 2 | SaaS companies, B2B software | Enterprise customers ask for it | 3-12 months | $50K - $200K+ |
| ISO 27001 | Global companies, EU customers | International deals, RFPs require it | 6-18 months | $40K - $150K+ |
| PCI DSS | Anyone handling payment cards | You process, store, or transmit card data | 3-6 months (SAQ) | $20K - $500K+ |
| NIST CSF | Government contractors, critical infrastructure | Federal contracts, cyber insurance | 3-12 months | $30K - $100K+ |
SOC 2
The gold standard for SaaS security
What is SOC 2?
SOC 2 (Service Organization Control 2) is a security framework developed by the American Institute of CPAs (AICPA). It proves that your company handles customer data responsibly across five Trust Service Criteria: Security, Availability, Processing Integrity, Confidentiality, and Privacy.
Think of it as a security report card. An independent auditor examines your systems, processes, and controls, then issues a report that you can share with customers and prospects.
Why Do You Need It?
If you sell software or services to other businesses, especially mid-size and enterprise companies, they will ask for your SOC 2 report. It has become table stakes for B2B SaaS.
- Close bigger deals: Enterprise buyers will not sign without it
- Shorten sales cycles: No more 50-question security questionnaires
- Build trust: Independent verification beats "trust us"
- Reduce risk: The process actually improves your security
The Business Case
ISO 27001
The international standard for information security
What is ISO 27001?
ISO 27001 is an internationally recognized standard for information security management systems (ISMS). Published by the International Organization for Standardization, it is the global benchmark for how organizations should manage and protect sensitive information.
Unlike SOC 2 (which is a report), ISO 27001 is a certification. An accredited body audits your organization and, if you pass, you receive a certificate valid for three years (with annual surveillance audits).
Why Do You Need It?
If you do business internationally, especially in Europe, Asia, or with government entities, ISO 27001 is often required. It is the compliance framework the rest of the world recognizes.
- Win international deals: Required for many EU and APAC contracts
- Meet regulatory requirements: Supports GDPR, HIPAA, and other regulations
- Competitive advantage: Stand out in RFPs and procurement processes
- Systematic approach: Build a mature, sustainable security program
The Business Case
PCI DSS
Required if you touch payment card data
What is PCI DSS?
PCI DSS (Payment Card Industry Data Security Standard) is a set of security requirements for any organization that accepts, processes, stores, or transmits credit card information. It was created by the major card brands to protect cardholder data.
This is not optional. If you handle payment cards, you must comply. The level of validation depends on your transaction volume, from a simple self-assessment questionnaire (SAQ) to a full on-site audit.
Why Do You Need It?
PCI DSS is mandatory, not voluntary. Non-compliance can result in fines, increased transaction fees, or losing the ability to accept credit cards altogether.
- Avoid fines: Penalties range from $5,000 to $100,000 per month
- Prevent breaches: Card data breaches average $4.2M in costs
- Maintain merchant status: Non-compliance can terminate your account
- Reduce liability: Compliance shifts some breach liability to card brands
The Business Case
NIST CSF
The flexible, risk-based cybersecurity framework
What is NIST CSF?
The NIST Cybersecurity Framework was developed by the National Institute of Standards and Technology to help organizations manage cybersecurity risk. It organizes security activities into five core functions: Identify, Protect, Detect, Respond, and Recover.
Unlike other frameworks, NIST CSF is designed to be flexible and scalable. It does not prescribe specific controls. Instead, it provides a structure for understanding and improving your security posture based on your specific risks.
Why Do You Need It?
NIST CSF is increasingly required for federal contractors and is often referenced in cyber insurance policies. Even if not required, it is an excellent foundation for building a mature security program.
- Win government contracts: Required or preferred for federal work
- Lower insurance premiums: Insurers recognize NIST CSF alignment
- Flexible adoption: Scale to your size and risk profile
- Foundation for other frameworks: Maps well to SOC 2, ISO 27001, and more
