SaaS Security Compliance? SOC 2, GDPR, CCPA, ISO27001... What’s Important to Know?

If you’re running a modern business, odds are your tech stack is packed with SaaS applications—CRMs, HR platforms, collaboration tools, marketing software, cloud storage, and more. SaaS offers speed and scalability, but it also introduces a hidden challenge: compliance.

Whether you're preparing for a SOC 2 audit, handling GDPR data requests, or vetting vendors for ISO 27001 readiness, staying compliant while managing dozens (or hundreds) of SaaS tools is no small feat.

So what do these compliance acronyms actually mean for your business? And how can you reduce SaaS security risks without drowning in audits?

The Big Four in SaaS Security Compliance

Here’s a quick breakdown of the most frequently cited frameworks and what they mean for your organization:

• SOC 2: Developed by the AICPA, SOC 2 focuses on how service providers securely manage customer data. It’s crucial for B2B SaaS companies working with enterprise clients. It’s not legally required—but for trust and due diligence, it’s table stakes.

• GDPR: This European regulation governs how businesses collect, store, and process personal data. If you serve EU-based customers or employees, GDPR applies. Non-compliance can result in fines of up to €20 million or 4% of global annual turnover—whichever is higher.

• CCPA: California’s answer to GDPR. If you handle data from California residents and meet certain thresholds (like $25M+ in revenue), you’re on the hook. The CCPA gives consumers rights to access, delete, and opt out of the sale of their personal data.

• ISO 27001: The international standard for information security management. If your organization wants to demonstrate mature risk management practices, this is the gold standard.

Other frameworks—like HIPAA, PCI DSS, and FedRAMP—may also apply depending on your industry. But the above four form the core of most SaaS compliance conversations.

What Actually Matters More Than the Acronyms

Compliance frameworks are helpful, but real SaaS security goes beyond passing an audit. These are the core elements that actually reduce risk:

• Know Your Data: What data are you collecting, where is it stored, and who can access it? Without full visibility, you're flying blind. Use a SaaS discovery and shadow IT detection tool to uncover all the third-party apps connected to your environment.

• Review Vendor Security: Each SaaS provider you use is a potential weak link. Ask for their SOC 2 reports, privacy practices, and how they handle data encryption and incident response.

• Enforce Least Privilege Access: Use GRC tools to ensure only necessary users have access to sensitive systems. Leverage role-based access controls and monitor for privilege creep.

• Encrypt Everything: Ensure all data—whether at rest or in transit—is protected with TLS 1.2+ and AES-256 encryption standards.

• Have a Response Plan: If a breach occurs, how quickly can you detect it, contain it, and notify affected stakeholders? Incident response is often the deciding factor in whether a compliance failure becomes a PR disaster.

• Automate and Audit Continuously: Compliance is not a one-and-done. Automate your continuous compliance monitoring, and regularly test your SaaS environment for drift, misconfigurations, or unauthorized OAuth connections.

Discover the SaaS You Didn’t Know You Had

Most companies fail to meet compliance not because they’re careless—but because they’re unaware of all the SaaS tools employees connect to company data. That’s where risk starts.

Try the Free OAuth SaaS Discovery Tool by Waldo Security to instantly see which third-party apps have access to your Google Workspace or Microsoft 365 environment. It’s a fast, automated way to flag risky apps, unknown vendors, and unused tokens before they turn into compliance failures.
