Data Loss Prevention

Safeguard sensitive information with Cloudflare DLP

Protect sensitive data across web, SaaS, email, and cloud traffic. Identify confidential information, enforce security policies, and log everything to prevent data leaks and support regulatory compliance.

Secure GenAI usage

Analyze GenAI prompts and responses for content and intent, then block suspicious behavior to govern workforce AI usage and protect data.

Unify policy management

Configure DLP profiles, detection entries, and Microsoft Purview sensitivity labels to consolidate protections across outbound traffic, documents, PDFs, and images.

Simplify SaaS and cloud security

Scan SaaS apps and cloud environments to identify sensitive data at rest. Implement targeted remediation steps to reduce data exfiltration risks.

Reduce manual detection reviews

Give feedback per detection to train AI context analysis and improve detection accuracy. DLP adapts to your specific data patterns and traffic to reduce false positives.

Fast and secure by default

Cloudflare DLP is built on our developer platform, employing advanced algorithms that ensure high-performance detections — even for compute-intensive workloads like AI context analysis or AI prompt protection.

You can use DLP to:

See reference architecture

Govern workforce AI usage

Detect and secure data entered into web-based AI tools. Apply guardrails to block risky prompts before sensitive data ever reaches an AI model.

Safeguard sensitive information

Reduce data exposure by securing sensitive assets across channels, including confidential documents in SaaS apps, source code in public repositories, PII sent via unsanctioned apps or emails, and more.

Comply with evolving regulations

Capture audit logs for DLP matches and policy actions, and forward them to external SIEM or cloud storage destinations as needed.

Frequently asked questions

Cloudflare Data Loss Prevention (DLP) is a cloud-native security solution that safeguards sensitive information across web, SaaS, email, and cloud traffic. It allows organizations to identify confidential data, enforce security policies, and log all activity to prevent exfiltration and support regulatory compliance.
Cloudflare DLP secures GenAI workflows by actively analyzing user prompts and AI responses for sensitive content and malicious intent. Security teams can apply inline guardrails to block risky behavior and prevent confidential data, like PII or source code, from ever reaching external AI models.
Yes. Cloudflare DLP unifies policy management across multiple file types, scanning outbound web traffic, text documents, PDFs, and images. For example, it utilizes predefined DLP profiles, custom detection entries, and Microsoft Purview sensitivity labels to consolidate data protection across all corporate environments.
Cloudflare DLP works together with CASB to scan connected SaaS applications and cloud storage environments to identify exposed sensitive data at rest. Once identified, administrators can implement targeted remediation steps directly within the platform to immediately reduce data exfiltration risks.
Cloudflare DLP reduces false positives by utilizing advanced algorithms and AI context analysis that adapt to an organization's specific traffic and data patterns. Security teams can provide direct feedback on individual detections to train the AI, improving long-term detection accuracy and significantly reducing manual review times.
