Getting Started with SaaS Security: A Practical Guide for Modern Enterprises

SaaS is everywhere. From finance and HR to engineering and marketing, SaaS apps now power the daily work of almost every team in your company, with employees driving SaaS adoption. By 2030, 80% of enterprise SaaS is expected to be business-led, meaning teams outside of IT will initiate, buy, and use apps independently, outside traditional procurement and security processes. However, as SaaS adoption skyrockets, most companies are operating without a clear strategy for securing it. There's a dangerous assumption that SaaS apps are secure “by default.” Spoiler alert: they’re not. This guide breaks down the essentials of SaaS security—what it is, where the risks are, and how to build a strategy that scales with your business. Whether you're just beginning to address SaaS security or seeking to fix what’s not working, we’ll show you how to improve your security without slowing down your business.

What is SaaS security?

SaaS security is the practice of protecting the data, users, and identities behind the cloud-based applications your teams use every day. These apps live outside your infrastructure and often outside your visibility and control. Most SaaS tools are easy to adopt. Some require a subscription, others offer free “freemium” access. All users need is an email and a password. That ease of access is great for productivity, but challenging for security.

SaaS security starts with understanding how apps are used, what data flows through them, and who has access. From there, it’s about building the right guardrails to reduce risk, without slowing down the business. This guide gives you the foundation to understand the key principles of SaaS security and how to build a practical, scalable framework that actually works.

How is SaaS security different from other types of security?

Unlike on-premise software or even cloud infrastructure that you manage, SaaS apps are entirely external and often exist beyond your visibility and governance. You don’t always know when employees have started a new subscription. You may not control the authentication. And that makes visibility tough, and enforcement even tougher.

Legacy controls like firewalls, endpoint agents, or network monitors weren’t built for SaaS. They miss what matters most: securing identity and access, ensuring business-critical SaaS is configured correctly, and detecting and mitigating identity threats as they arise. Modern SaaS security is different. It’s not about locking everything down; it’s about building smart guardrails that keep your business secure while teams move fast.

This guide will show you what that looks like—and how to get started.
