Tailored for Secure Data Masking

Protecto’s intelligent masking techniques safeguard sensitive information while preserving usability, ensuring compliance and seamless integration across systems and AI applications.

Format-Preserving Masking

Retain the original data structure while anonymizing sensitive details.

Example: “555-123-4567” becomes “123-456-7890” for phone numbers

Type-Preserving Masking

Substitute data with values of the same type to maintain compatibility.

Example: Numeric values “12345” masked as “67890.”

Length-Preserving Masking

Ensure masked data matches the original length to prevent system disruption.

Example: Credit card “4821 7394 1058 2637” becomes “9274 3810 5629 8471.”

Context-Preserving Masking

Protect sensitive information while retaining semantic meaning for AI/ML applications.

Example: Emails like “jane.doe@example.com” become “user.abc@maskedmail.com.”
