DataStealth is a Data Security Platform purpose-built to protect sensitive data across enterprise environments. Leveraging configurable policies, DataStealth identifies which data elements require protection and apply the appropriate data protection methodology - most commonly tokenization, encryption or masking - based on organizational risk tolerance and compliance requirements.

Organizations implementing DataStealth can choose between tokenization and encryption to safeguard their data. While both approaches aim to protect sensitive information, it is critical to understand the fundamental differences between them to make informed decisions during deployment.
See it in action →DataStealth provides three core methodologies; Tokenization, Masking, and Encryption. Each is configurable at the data-element level through policy-driven rules. Combined with continuous monitoring, real-time classification, and broad technology integrations, DataStealth ensures sensitive data is always protected across structured and unstructured environments, on-premises and in the cloud.
Tokens look and act like real data, so your workflows keep running smoothly.
Deterministic tokens ensure joins, dedupes, and analytics all still work.
Make tokens permanent, reversible, or time-bound; you decide.
Mask sensitive fields on the fly; show “last 4 digits,” redact logs, or use realistic dummy data.
Obfuscate datasets permanently for analytics, training, or sharing.
Apply different masking rules by role, region, or device for true zero-trust enforcement.
Go beyond blanket encryption. Secure the fields that matter most for speed and compliance.
Encrypt data like credit cards while keeping formats intact to avoid breakage.
Enforce TLS 1.2+ and mTLS to secure every network hop.

Deterministic: Same input → same token (supports joins, deduping, analytics).
Randomized: Same input → different tokens (maximizes privacy).
Reversible: Brokered, audited detokenization for workflows requiring real values.
Irreversible: One-way pseudonyms for permanent de-identification.
Format- and length-preserving tokens for compatibility with existing schemas.
Character-set controls for phone numbers, emails, IDs, addresses.
Checksum-aware tokens for PCI and similar fields.
Global tokens for enterprise-wide consistency.
Scoped tokens per app, tenant, or geography.
Time-bound and revocable tokens to limit long-term exposure.
Policy-driven reveal and break-glass detokenization.
Partial tokenization (e.g., “last-4”) for support use cases.
Multi-field deterministic correlation across related values.
Static masking for permanent obfuscation in datasets, exports, and sandboxes.
Dynamic masking for role-based, on-the-fly masking in applications.
Redaction for logs, tickets, and documents.
Partial reveal (e.g., “****1234”, j***@example.com).
Generalization/banding (e.g., “Age 30–39”).
Date shifting to preserve intervals without real dates.
Hashing/irreversible masking for joins and deduplication.
Realistic pseudonyms for training, QA, and demos.
Deterministic masking for stable joins and analytics.
Format- and length-preserving options for schema integrity.
Checksum-aware masking for PAN formats.
Role- and attribute-based masking across roles, tenants, and geographies.
Context-aware masking by device, source, risk score, or sensitivity.
Field- and row-level granularity, including nested JSON.
Works across structured and unstructured data sources.
Full-stack encryption: data at rest + in transit.
Field-level encryption for specific columns or JSON fields.
File/object encryption for documents, blobs, and data lakes.
Fragment-aware encryption for distributed storage architectures.
Symmetric AES-GCM (authenticated, low latency) and AES-CBC + HMAC.
Format-preserving encryption (FF1/FF3) for PANs and IDs.
Deterministic encryption for joins and lookups.
Envelope encryption: master keys protecting data keys.
TLS 1.2+ for all connections; mTLS and certificate pinning for zero-trust.
Tokenization replaces sensitive data with non-reversible or reversible surrogate values (tokens) that retain the original format and length, allowing applications, analytics, and workflows to continue operating without code changes.
Data masking obfuscates data by replacing it with realistic but fictitious values, redacted characters, or generalized ranges. It’s often used for test environments, customer support views, and log sanitization.
Encryption transforms data into ciphertext using cryptographic algorithms, making it unreadable without the corresponding decryption key.
The right method depends on the use case:
For a detailed comparison, read Tokenization vs Encryption vs Masking.
Format-preserving encryption (FPE) encrypts data while maintaining its original format, length, and character set, i.e., a 16-digit credit card number encrypts into another 16-digit number, a 9-digit SSN encrypts into another 9-digit value.
This is critical when downstream systems validate field formats (checksum validation, database schema constraints, API contracts) and cannot accept arbitrarily formatted ciphertext.
DataStealth supports FPE using FF1/FF3 algorithms alongside standard AES-GCM for bulk encryption and field-level encryption for targeted protection.
Use FPE when you need cryptographic security but cannot modify database schemas or application logic to accommodate standard ciphertext formats, as is common in mainframe environments, legacy payment systems, and cross-border data transfer pipelines where format compliance is mandatory.
Perimeter-based security (e.g., firewalls, network segmentation, VPNs, etc) protects the infrastructure surrounding data but leaves the data itself unprotected once an attacker breaches the perimeter.
Data-centric security inverts this model: protections travel with the data itself through tokenization, masking, or encryption applied at the field level.
If tokenized data is exfiltrated, it is useless to the attacker (whether today or in the future, including against quantum computing threats).
DataStealth's Data Security Platform implements data-centric protection by applying policies directly to sensitive data elements after discovery and classification, ensuring that data is protected regardless of where it moves, i.e., across SaaS applications, file shares, cloud environments, or on-premise systems.
For a strategic overview, see The Ultimate Guide to Data Security Platforms.
When sensitive data is tokenized, the systems that store and process tokens are no longer considered in scope for regulatory audits because tokens are not classified as cardholder data under PCI DSS or as protected health information under HIPAA.
This scope reduction translates directly to lower compliance costs: fewer systems to assess, fewer controls to document, and faster audit cycles.
DataStealth enables this by applying tokenization at the data layer – i.e., before data reaches applications, databases, or analytics pipelines – so downstream systems never see real sensitive values.
