What is SaaS Data Loss Prevention?
SaaS Data Loss Prevention (DLP) refers to a modern security approach that protects sensitive data—such as PII, PHI, or financial records—stored and shared within Software-as-a-Service platforms like Google Workspace, Office 365, Salesforce, Slack, and more.
Unlike traditional DLP tools that were focused on endpoints or on-premises systems, SaaS DLP is designed to address the cloud-first, collaboration-heavy, and remote-enabled work environments of today.
It discovers and classifies sensitive data, monitors usage, and enforces policies to prevent data leaks—accidental or malicious.
Why Modern DLP for SaaS is Important?
SaaS has fundamentally changed the way businesses operate. Employees can work from anywhere, share files instantly, and integrate third-party apps without IT approval. But this flexibility comes with serious risks:
- Sensitive data is everywhere: From emails to Slack threads to Google Docs.
- Shadow IT is rampant: Users install unsanctioned tools that can leak data.
- Old-school DLP can’t see cloud activity: Traditional tools miss SaaS-specific risks.
Modern SaaS DLP addresses these challenges by providing visibility and control across all SaaS platforms your organization uses.
The Challenges of Protecting SaaS Data
SaaS data can be accessed from anywhere
Your team is global. Remote. Always online. That means:
- There’s no corporate perimeter anymore.
- Sensitive data is accessed from personal devices, home networks, and mobile apps.
- VPNs and firewalls are no longer sufficient.
SaaS DLP ensures protection travels with the data, not the device.
Shadow IT applications
Employees install tools like productivity apps, AI assistants, or integrations without IT knowing. These tools often request permission to access emails, calendars, and documents—and just like that, sensitive data is exposed.
SaaS DLP helps detect unauthorized apps and prevent data from flowing into insecure environments.
Steps To Implementing DLP for SaaS Applications
1. Data Classification
You can’t protect what you can’t see. The first step is identifying and labeling data—SSNs, credit cards, health records, financial info, IP, etc.
Tools like Strac automatically scan SaaS apps and tag data based on sensitivity, helping you apply the right controls.
2. Cloud Provider Evaluation
Ensure the SaaS vendors you use follow security best practices. Look for:
- SOC 2, ISO 27001, and HIPAA compliance
- Encryption in transit and at rest
- Detailed logging and access controls
3. Encryption and Tokenisation
While SaaS vendors may encrypt data by default, layering your own encryption or tokenization ensures that even if a breach occurs, your data remains unreadable.
4. Access Controls and Identity Management
Enforce role-based access and integrate with identity providers like Okta, Azure AD, or Google Workspace.
Enable:
- Multi-Factor Authentication (MFA)
- Just-in-time access
- Least privilege principles
5. Monitoring and Logging
Track who accesses sensitive data, from where, and when. Continuous monitoring helps:
- Detect anomalies
- Investigate incidents
- Prove compliance
6. Data Loss Prevention Tools
Deploy SaaS-aware DLP tools like Strac to:
- Discover and classify sensitive data
- Block or redact exposure (e.g., external file sharing, risky AI tools)
- Alert security teams in real-time
7. Employee Training and Awareness
Human error remains the top cause of data breaches.
- Conduct regular training on phishing, data handling, and secure sharing.
- Reinforce policies with context-aware alerts when risky actions occur.
8. Incident Response Plan
Be ready to act. Build a response plan that includes:
- Containment steps (e.g., revoke access)
- Investigation procedures
- Notification workflows (for compliance with HIPAA, GDPR, etc.)
Additional Challenges & Considerations
- Multi-tenancy risk in SaaS environments.
- Lack of visibility across app-to-app integrations.
- Legal and compliance obligations vary by data type and region.
- BYOD policies create blind spots without agentless coverage.
What are the Benefits of SaaS DLP?
- Prevents data breaches by monitoring sensitive data in real time.
- Supports compliance with HIPAA, PCI, GDPR, and more.
- Reduces shadow IT risk by flagging unsanctioned tools.
- Improves visibility into where sensitive data resides and who accesses it.
- Boosts productivity by enabling secure collaboration instead of blocking it.

Frequently Asked Questions
What are the 3 types of data loss prevention?
- Network DLP: Monitors data in motion across the network.
- Endpoint DLP: Controls data on user devices (laptops, USBs).
- Cloud/SaaS DLP: Protects data stored or shared in SaaS apps like Google Drive, Slack, and O365.
Why is it difficult to protect SaaS cloud data?
Because:
- SaaS data resides outside your traditional perimeter.
- Multiple users and devices can access it anytime, anywhere.
- There’s limited visibility without purpose-built tools.
What kinds of activities can a DLP tool perform to protect data resources?
- Automatically detect sensitive data (PII, PHI, PCI)
- Alert or block unauthorized sharing
- Redact data from messages or files
- Monitor risky behavior
- Generate audit trails for compliance
Why is it important to classify data as it enters the IT environment?
Classification enables you to:
- Prioritize protection based on sensitivity
- Apply appropriate policies (e.g., block external sharing)
- Avoid over-blocking benign content
- Reduce false positives in alerting
