If you’ve ever wondered whether you need GDPR compliance, what PCI DSS actually requires, or why your enterprise customers keep asking about SOC 2, you’re not alone. This guide cuts through the complexity to explain the cybersecurity compliance standards that matter most in 2026, including what they protect, who needs them, and how to figure out which ones apply to your organization.
Whether you’re a startup handling your first customer data, a growing company pursuing enterprise contracts, or an established business expanding internationally, understanding these frameworks is essential to protecting your organization, building customer trust, and staying on the right side of the law.
Key Takeaways
- Cybersecurity compliance requirements depend on your data types and geography. The data you handle—whether it’s payment cards (PCI DSS), EU personal data (GDPR), US health records (HIPAA), or California resident information (CCPA)—determines which frameworks apply to your organization.
- Three main compliance categories exist: voluntary global frameworks (ISO 27001), industry-specific requirements (PCI DSS, HIPAA), and mandatory regional regulations (GDPR, NIS2). Understanding which category affects your business helps you prioritize compliance efforts.
- SOC 2 and ISO 27001 are becoming essential for B2B (business-to-business) companies. If you’re selling to enterprise customers or pursuing international business, these frameworks demonstrate security maturity and are often required to win contracts.
- Start with what’s legally mandatory, then add what your market demands. Focus on implementing genuine security controls that protect your organization rather than just checking boxes for auditors—effective compliance makes you more secure in reality, not just on paper.
Which Types of Data Need Protecting?
Not all data carries the same risk—or the same regulatory requirements. Understanding what types of data your organization handles is the first step toward choosing the right compliance framework.
Here are the major categories that trigger specific compliance obligations:
- Personal Identifiable Information (PII) includes any data that can identify an individual person: names, email addresses, phone numbers, Social Security numbers, or even IP addresses. This is what regulations like GDPR and CCPA are designed to protect.
- Protected Health Information (PHI) covers medical records, insurance information, prescription history, and any health data linked to an identifiable person. If you touch PHI, HIPAA compliance becomes mandatory in the United States.
- Payment Card Information (PCI) means credit card numbers, CVV codes, and cardholder data. Any business that processes, stores, or transmits payment card information must comply with PCI DSS—from major retailers to small e-commerce shops.
- Financial Records encompass bank account information, investment portfolios, loan applications, and transaction histories. These trigger requirements under regulations like GLBA in financial services or DORA for financial institutions in the EU.
- Intellectual Property and Trade Secrets might not trigger specific regulations, but they’re often your most valuable assets. Frameworks like ISO 27001 help protect proprietary algorithms, product designs, and business strategies from theft or espionage.
- Critical Infrastructure Data includes operational technology systems, SCADA networks, and industrial control systems. If you operate power grids, water systems, or telecommunications networks, frameworks like the NIS2 Directive or NERC CIP apply.
The type of data you handle often determines which compliance standards you’ll need, but geography and industry add another layer of complexity.
What Are the International Compliance Standards for Cybersecurity?
International compliance standards for cybersecurity are structured frameworks that establish security requirements, best practices, and verification processes to protect data and digital assets. These standards serve as blueprints for building security programs, with some offering voluntary certification (like ISO standards) while others impose legally binding requirements with penalties for non-compliance (like GDPR).
Think of them as the rulebooks that define what “good cybersecurity” looks like, whether you’re a small business protecting customer emails or a multinational corporation securing billions of financial transactions.
These standards emerged because cyberattacks don’t respect borders. When Sony’s PlayStation Network was breached in 2011, 77 million user accounts were compromised across dozens of countries. When WannaCry ransomware spread in 2017, it hit over 200,000 computers in 150 countries within days. Individual countries couldn’t solve these problems alone. We needed international cooperation and shared security standards.
Some standards are truly global (ISO 27001 works the same in Tokyo, Toronto, or Tel Aviv), while others are regional but have worldwide influence because of their economic reach (GDPR affects any company serving EU residents, regardless of where that company is headquartered).
The landscape can feel overwhelming, but most standards fall into three categories:
- Voluntary global frameworks that demonstrate security maturity
- Industry-specific requirements that protect particular types of sensitive data
- Mandatory regional regulations that carry legal consequences for non-compliance

Let’s look at each of these compliance standards in more detail.
ISO/IEC 27001 (Information Security Management)
Why it exists: Developed by the International Organization for Standardization, ISO 27001 provides a systematic approach to managing sensitive information through an Information Security Management System (ISMS). It’s the world’s most recognized information security standard.
Data it protects: All types of organizational data, including customer PII to intellectual property, financial records, and employee information.
Who’s most likely to use it:
- Organizations pursuing international business (especially in Europe)
- Technology companies seeking to demonstrate security maturity
- Service providers looking to win enterprise contracts
- Companies building a foundation for multiple compliance requirements
NIST Cybersecurity Framework 2.0
Why it exists: The National Institute of Standards and Technology created this framework after President Obama’s 2013 executive order following major critical infrastructure attacks. While originally designed for U.S. critical infrastructure, it’s become a globally recognized voluntary framework.
Data it protects: All data types, with particular emphasis on critical infrastructure and operational technology environments.
Who’s most likely to use it:
- U.S. government contractors and agencies
- Critical infrastructure operators (energy, healthcare, financial services)
- Organizations preferring a flexible, risk-based approach
- Companies looking for a framework that aligns with other standards
ISO/IEC 42001 (AI Management)
Why it exists: As artificial intelligence systems became embedded in business operations, ISO 42001 (published in December 2023) emerged as the first international standard for responsible AI development and deployment.
Data it protects: AI training data, model outputs, algorithmic decision-making processes, and personal data processed by AI systems.
Who’s most likely to use it:
- AI developers and technology companies building AI products
- Organizations deploying AI for high-stakes decisions (hiring, lending, healthcare)
- Companies subject to the EU AI Act or similar AI regulations
- Businesses seeking to demonstrate responsible AI governance
PCI DSS (Payment Card Industry Data Security Standard)
Why it exists: PCI DSS isn’t government-mandated, but it’s enforced through contracts with payment card brands. Non-compliance can result in fines of $5,000-$100,000 per month, increased transaction fees, or even losing the ability to process credit card payments. It was created by major credit card companies (Visa, Mastercard, American Express, Discover, JCB) after massive data breaches exposed millions of payment cards.
Data it protects: Credit card numbers, cardholder names, expiration dates, CVV codes, and any data printed on or embedded in payment cards.
Who’s most likely to use it:
- E-commerce businesses processing online payments
- Retailers with point-of-sale systems
- Payment processors and merchant service providers
- Any organization that stores, processes, or transmits cardholder data
GDPR (General Data Protection Regulation) – EU
Why it exists: Implemented in May 2018, the GDPR revolutionized data privacy by giving EU residents unprecedented control over their personal data. It came about from growing concerns about data exploitation, inadequate breach notifications, and lack of individual privacy rights in the digital age.
Data it protects: Any personal data relating to EU residents, from basic identifiers like names and email addresses to sensitive categories like health information, biometric data, political opinions, and online behavior.
Who’s most likely to use it:
- Any organization offering goods or services to EU residents
- Companies monitoring EU residents’ behavior (including through cookies and analytics)
- International businesses with EU subsidiaries or employees
- Data processors handling data on behalf of EU-based organizations
NIS2 Directive (Network and Information Security) – EU
Why it exists: Building on the original 2016 NIS Directive, NIS2 (in effect since October 2024) expands cybersecurity requirements to more sectors and organizations across the EU. It addresses the increasing sophistication of cyberattacks against critical infrastructure and essential services.
Data it protects: Data within essential and important entities’ networks and information systems, particularly operational data critical to service continuity in sectors like energy, transport, healthcare, and digital infrastructure.
Who’s most likely to use it:
- Medium and large organizations in essential sectors (energy, transport, banking, healthcare, digital infrastructure)
- Important entities in sectors like postal services, waste management, chemicals, food, and manufacturing
- Supply chain partners of essential entities
- Digital service providers catering to European markets
CCPA (California Consumer Privacy Act) – California, US
Why it exists: Enacted in 2018 and enhanced by CPRA (California Privacy Rights Act) in 2023, CCPA gives California residents similar privacy rights to GDPR, establishing the strongest consumer privacy protections in the United States.
Data it protects: Personal information of California residents, including identifiers, commercial information, biometric data, internet activity, geolocation data, professional information, and inferences drawn from this data.
Who’s most likely to use it:
- Businesses with annual revenues over $25 million
- Companies that buy, sell, or share personal information of 100,000+ California consumers
- Businesses deriving 50%+ of revenue from selling/sharing personal information
- Most mid-size to large companies serving California customers
HIPAA / HITRUST CSF – US
Why they exist: HIPAA (1996) establishes national standards for protecting medical information in the United States. HITRUST CSF (created in 2007) builds on HIPAA by combining requirements from multiple standards into a single framework for healthcare organizations.
Data they protect: PHI, which is any health information that can be linked to an individual, including medical records, lab results, prescription information, billing data, and even appointment schedules.
Who’s most likely to use them:
- HIPAA: Healthcare providers, health insurance companies, healthcare clearinghouses, and their business associates (including cloud providers, IT vendors, and billing services)
- HITRUST: Healthcare organizations seeking to demonstrate comprehensive security, especially those needing to meet multiple compliance requirements simultaneously or serving customers requiring HITRUST certification
FedRAMP (Federal Risk and Authorization Management Program) – US
Why it exists: Created in 2011, FedRAMP standardizes the security assessment and authorization process for cloud services used by federal agencies, eliminating redundant assessments and accelerating secure cloud adoption.
Data it protects: Federal data processed, stored, or transmitted through cloud service offerings, ranging from low-impact public information to high-impact sensitive government data.
Who’s most likely to use it:
- Cloud service providers seeking federal government customers
- SaaS, PaaS, and IaaS vendors serving federal agencies
- Technology companies with government cloud products
- Managed service providers supporting federal IT infrastructure
SOC 2 (Service Organization Control 2) – US
Why it exists: Developed by the American Institute of CPAs (AICPA), SOC 2 developed as service providers moved critical business operations to the cloud and enterprises needed assurance that their vendors were protecting data appropriately. Unlike compliance checklists, SOC 2 evaluates how well an organization actually implements and maintains its security controls over time.
Data it protects: Customer data processed by service organizations, including any information entrusted to SaaS platforms, cloud infrastructure providers, managed service providers, and other technology vendors. The framework is designed to protect the security, availability, processing integrity, confidentiality, and privacy of customer data.
Who’s most likely to use it:
- B2B SaaS companies selling to enterprise customers
- Cloud service providers and hosting companies
- Managed service providers and IT outsourcing firms
- HR, payroll, and benefits administration platforms
- Any technology vendor that stores, processes, or transmits customer data
