Beyond Basic Google DLP: Smart Tricks for Bulletproof Data Security

Every organization faces a tough reality: sensitive data is both a prized asset and a potential liability. According to recent industry research, insider threats and accidental data leaks are on the rise, with cloud email and file sharing platforms like Google Workspace and Microsoft 365 at the center of the storm. While Google’s built-in Data Loss Prevention (DLP) tools offer a solid foundation, many security teams find themselves asking: “Is basic DLP enough to keep our data truly safe?” Let’s explore how you can move beyond the basics, using smarter strategies and advanced tools to lock down your data—without slowing down your business.

Why Basic Google DLP Isn’t Always Enough

Understanding Google DLP’s Core Features

Google Workspace DLP helps organizations control how sensitive data is shared and accessed within Google’s suite of productivity apps. It lets admins:

• Set rules to monitor and block unauthorized sharing of sensitive data in Google Docs, Drive, Sheets, and more
• Use AI-driven scans and alerts to detect risky behavior or potential breaches
• Automate incident management to respond quickly to threats

These features are a great start, especially for organizations that operate entirely within Google’s ecosystem.

The Gaps: Where Basic DLP Falls Short

But here’s the catch: Google’s DLP is designed for Google environments. If your team uses third-party apps, collaborates with external partners, or stores sensitive data outside Google’s core apps, you may be exposed. Common challenges reported by IT leaders on G2 and Gartner include:

• Limited visibility into data movement across non-Google platforms
• Difficulty managing complex permissions in Google Drive
• Gaps in detecting sophisticated insider threats or account takeovers

Imagine a scenario where a sensitive contract is downloaded from Google Drive and then uploaded to a personal Dropbox account. Basic DLP might not catch this.

Smart Tricks for Bulletproof Data Security

1. Layered Data Classification and Policy Enforcement

Don’t rely on a single set of rules. Use a layered approach:

• Classify data by sensitivity (e.g., public, internal, confidential, regulated)
• Apply different DLP policies for each class
• Regularly review and update classifications as business needs change

Google Cloud DLP, for example, can scan both structured and unstructured data, detecting financial records, personal identifiers, and proprietary information. But pairing this with a platform that automates policy enforcement across all cloud services gives you broader coverage.

2. Advanced De-Identification Techniques

Go beyond simple redaction. Use:

• Masking: Replace sensitive data with placeholder characters
• Tokenization: Substitute sensitive data with unique tokens
• Format-preserving encryption: Encrypt data while keeping its original format
• Date-shifting: Obscure real dates to protect privacy

These techniques help keep data usable for business processes while reducing risk if it’s exposed.

3. Real-Time Threat Detection and Automated Response

Speed matters. The faster you detect and respond to a threat, the less damage it can do. Look for solutions that offer:

• AI-driven scans for unusual behavior (like mass downloads or suspicious sharing)
• Automated alerts and incident response workflows
• Integration with your existing security stack for seamless remediation

4. Identity and Access Management (IAM) Integration

Strong DLP is only as good as your identity controls. Combine DLP with IAM tools to:

• Enforce least-privilege access to sensitive files
• Detect and block risky permission changes
• Monitor for signs of account takeover (ATO) or business email compromise (BEC)

5. Continuous Monitoring and Audit Trails

Keep a detailed record of who accessed what, when, and how. This helps with:

• Investigating breaches or suspicious activity
• Meeting compliance requirements (like GDPR or HIPAA)
• Training staff on safe data handling

Quick Checklist: Smart DLP Moves

• Classify and label sensitive data
• Use advanced de-identification (masking, tokenization, encryption)
• Automate policy enforcement across all cloud apps
• Integrate DLP with IAM and threat detection tools
• Maintain real-time monitoring and detailed audit logs

How Material Security Raises the Bar

Material Security’s platform is built for organizations that need more than basic DLP. Here’s what sets it apart:

• Unified Protection: Combines email security, data protection, identity threat detection, and configuration management in one platform.
• Automated Remediation: Instantly responds to threats without blocking productivity or collaboration.
• Cloud-Native Integration: Works seamlessly with Google Workspace and Microsoft 365, covering both email and files.
• Identity-Centric Security: Focuses on protecting accounts from takeover, phishing, and BEC—top concerns for C-level executives and security teams.

“Material Security automates remediation of security issues while maintaining productivity and collaboration capabilities.”

Real-World Example: Securing Google Drive with Smart DLP

Let’s say your finance team stores quarterly reports in Google Drive. With basic DLP, you can block sharing outside the company. But what if someone downloads a report and emails it from a personal account? Material Security’s platform detects this risky behavior, alerts your team, and can automatically revoke access or require step-up authentication—before data leaves your control.
