Professional-Grade Data Protection, Made Simple

Choose the perfect method for any situation.

* Anonymize with Precision (Pseudonymization): Our most powerful feature. Swap real data with realistic, format-preserving fake data. With 30+ built-in types (Email, Credit Cards, Names, IP Addresses), it's
perfect for creating safe, high-quality test and analysis datasets.

* Hide & Redact: Instantly apply Character Masking to partially hide data (e.g., ****1234) or use full Redaction to replace it completely with [REDACTED].

* Scramble & Secure: Use Data Shuffling to make information unreadable or one-way Hashing (SHA-256) to create a secure, irreversible "fingerprint" of your data.
