2025 SaaS Security Threat Report: Key Takeaways and Defense Strategies

The 2025 SaaS Security Threat Report by Obsidian Security highlights critical insights into the evolving SaaS threat landscape. As SaaS becomes a prime target for attackers, defenders must adapt to protect enterprise environments effectively.

Key Findings from the Report:

• Top SaaS Attack Vectors in 2024 – Credential theft, misconfigurations, and API abuses lead the list.
• Nation-State & Cybercriminal Focus – Advanced actors increasingly exploit SaaS platforms for espionage and financial gain.
• Drivers Behind SaaS Attacks – Rapid SaaS adoption, poor access controls, and excessive permissions.
• Targeted Verticals – Finance, healthcare, and tech sectors face the most SaaS-based threats.
• 2025 Predictions:
• Expanding SaaS Attack Surface – More integrations mean more vulnerabilities.
• AI/LLM & Shadow SaaS Risks – Unmonitored AI-powered SaaS tools create blind spots.
• Non-Human Identities Targeted – Bots, service accounts, and API keys are new attack vectors.

You Should Know: Practical Defense Measures

1. Secure SaaS Access & Authentication

• Enforce MFA (Multi-Factor Authentication) for all SaaS logins.
• Use Conditional Access Policies (Azure AD, Okta) to restrict logins.

  </li>
  </ul>
  
  <h1>Example: Azure AD Conditional Access Policy (PowerShell)</h1>
  
  New-AzureADMSConditionalAccessPolicy -DisplayName "Restrict High-Risk Logins" -State "Enabled" -Conditions @{...} 
  

  2. Monitor SaaS Configurations & APIs

  • Regularly audit OAuth permissions and API access:

    </li>
    </ul>
    
    <h1>List authorized OAuth apps in Google Workspace</h1>
    
    gam print oauthtokens 
    

    – Use CIS benchmarks for SaaS platforms (e.g., Microsoft 365, Salesforce).

    3. Detect Shadow SaaS & AI Tool Risks

    • Deploy CASB (Cloud Access Security Broker) tools like Netskope or McAfee MVISION.
    • Scan for unauthorized AI tools with:

      </li>
      </ul>
      
      <h1>Use network traffic analysis to detect unapproved SaaS</h1>
      
      tcpdump -i eth0 'port 443' | grep "api.ai-tool.com" 
      

      4. Protect Non-Human Identities

      • Rotate API keys and service account credentials frequently:

        </li>
        </ul>
        
        <h1>Rotate AWS IAM keys</h1>
        
        aws iam update-access-key --access-key-id AKIAXXX --status Inactive 
        

        – Monitor anomalous bot activity with SIEM rules (e.g., Splunk, Sentinel).

        What Undercode Say

        SaaS security is no longer optional. Enterprises must:

        • Automate SaaS posture management with tools like Obsidian Security.
        • Train employees on SaaS phishing risks (e.g., fake OAuth consent screens).
        • Adopt Zero Trust for SaaS apps—verify every access request.

        Expected Output:

        • A hardened SaaS environment with reduced attack surface.
        • Real-time detection of SaaS-based threats.
        • Compliance with frameworks like NIST CSF and ISO 27001.
