Every organization has dozens (if not hundreds) of SaaS applications. But not every application poses the same level of security risk. Security teams are overwhelmed trying to secure everything everywhere. When they’re so strapped for time and resources, this means compromises are made, corners get cut, inconsequential security alerts are prioritized, and mistakes can happen—leaving their most valuable data vulnerable.
Threat actors have done the math. Specific SaaS platforms contain your most privileged identities, sensitive data, and business processes. Targeting those apps is efficient, lucrative, and increasingly common. Groups like ShinyHunters and Scattered Spider didn’t go after obscure tools; they went straight for Salesforce, Snowflake, and Okta, for example, because that’s where the leverage is. When security teams are stretched thin, and cracks appear in these critical apps, attackers are ready to take advantage.
The solution? Security teams need to prioritize securing the apps that have the most valuable business-critical data first.
Most of your SaaS risk lives in just a handful of apps
The SaaS security world has adopted the Pareto Principle: A framework that comes from economics, also referred to as the 80/20 rule. Today, this rule shows up everywhere, from sales (most revenue comes from a few customers) to time management (a handful of tasks drive most results).
In SaaS security, it simply means that a small number of applications account for most of your risk and sensitive data.
Not all SaaS apps are created equal when it comes to security risk. The majority (80% or more) of your most valuable and sensitive data lives in just a handful (20%) of your applications such as Salesforce, ServiceNow, Microsoft 265, and WorkDay. This is precisely why attackers target these apps.
Trying to secure every SaaS app at the same level is humanly impossible. Here’s why:
- Resource drain: You’ll burn out your team and still miss the biggest risks.
- Alert overload: More apps, more noise (meaning true threats get buried).
- Dangerous gaps: The riskiest apps (like Salesforce, ServiceNow, Microsoft 365, or Workday) don’t always get the attention they need.
In fact, according to our 2025 State of SaaS Security Report, 89% of breached organizations thought they had “appropriate visibility” at the time of the incident. This shows a huge gap between perceived security and actual security. Confidence alone isn’t enough if you’re spread too thin.
Rather than trying to lock down every tool equally, the most effective teams put their strongest controls around the critical few, then scale their efforts outward as resources allow.
Focusing on the top 10-20% doesn’t mean ignoring the rest. It just means you start where the risk is highest, and then scale up as you build repeatable processes. Most incidents, compliance headaches, and breaches start with the big apps, so get those right first.
Why are we talking about this now? Why is prioritization essential today?
Traditional security programs were built around protecting the network perimeter. But today’s SaaS environments look very different. Business-critical data is spread across hundreds of applications, each with its own users, configurations, integrations, and identities.
That complexity creates three common challenges:
- Unclear ownership: SaaS security often spans security, IT, business owners, and application administrators, making accountability difficult.
- Too many competing priorities: Many organizations know they need stronger SaaS security but struggle to dedicate time and resources to building a mature program.
- Limited visibility: You can’t prioritize what you can’t see. Many organizations still lack a complete inventory of the SaaS applications, integrations, and identities (including AI agents) operating across their environment.
Rather than trying to solve every problem at once, successful organizations take an incremental approach, starting with their most business-critical applications and expanding their program over time.
Recent high-profile SaaS incidents have shown why this approach matters. In the Snowflake-related attacks, attackers didn’t rely on sophisticated exploits. Instead, they took advantage of stolen credentials, weak authentication practices, and configuration gaps to access sensitive environments. The lesson wasn’t simply to “turn on MFA.” It was that foundational security controls applied consistently across your most critical applications can dramatically reduce risk.
How to build a SaaS security program for enterprise
The goal here isn’t to boil the ocean by securing every app perfectly on day one. Aim to build a program that prioritizes what matters now while laying the foundation for long-term maturity that will grow with your organization.
Walk: Secure your critical applications first
Start with the handful of SaaS applications that create the largest business impact if compromised.
Focus on:
- Identifying your highest-risk SaaS applications and establishing secure configuration baselines
- Enforcing multi-factor authentication everywhere possible and eliminating single-factor authentication
- Inventorying service accounts, third-party integrations, and connected applications
- Centralizing SaaS logs so you have visibility into activity across critical applications
Run: Operationalize SaaS security
Once the basics are in place, make SaaS security part of everyday operations.
This includes:
- Establishing configuration standards for critical applications
- Defining ownership using a RACI model so security, IT, and business teams understand their responsibilities
- Bringing procurement into the security review process before new SaaS applications are adopted
- Applying Zero Trust principles to identities, applications, and integrations
Fly: Continuously reduce risk
As your program matures, move beyond periodic reviews toward continuous visibility.
Focus on:
- Continuously monitoring for configuration drift as users, permissions, and applications change
- Feeding SaaS telemetry into existing SIEM and SOAR workflows to detect suspicious behavior faster
- Monitoring both human and non-human identities (including service accounts and API-based identities) to identify potential attack paths before they’re exploited
As organizations adopt AI-powered SaaS apps and autonomous agents, prioritization becomes even more important. AI introduces new identities, integrations, and automated workflows that can significantly expand an organization’s attack surface. The same principles apply: understand what business-critical systems AI can access, limit permissions appropriately, and continuously monitor both human and non-human identities.
Why does this approach actually work?
Here’s what to expect when security teams use the 80/20 mindset (aka Pareto Principle):
- Fewer incidents, more real alerts: Less noise and faster action on real risks.
- Better team morale: People know their work is moving the needle.
- Clearer reporting: Leadership understands progress and sees real reduction in risk.
As one CISO shared in our report: “We’ve been able to accelerate the identification and remediation of key security issues that would have otherwise led to potential data exposures and, potentially, fines or other penalties.”
The bottom line: Focus on where your most business-critical data lives
SaaS security doesn’t have to be overwhelming or complicated.
Successful SaaS security programs aren’t built by trying to secure every application equally. They’re built by understanding which applications matter most, how they’re connected, and where attackers are most likely to strike.
Start with the applications that create the greatest business impact. Strengthen those first. Then expand your program with repeatable processes and continuous visibility.
That’s how you reduce risk without overwhelming your team.
