Extend Modern Data Protection to the Mainframe.
Tokenization and encryption for systems that were never built for it.

"Untouchable" Core Systems
Mainframes running COBOL/DB2 can't run endpoint agents or accept code rewrites, yet they hold the most sensitive data in the enterprise.
The Hybrid Integration Attack Surface
Connecting mainframes to cloud, SaaS, and modern APIs multiplies the number of systems that can reach sensitive data, and most of those integration points were never designed with today's threat model in mind.
Encryption Alone Isn't Enough
Encryption is reversible with the right key; that's by design. Vaulted tokenization goes further: it removes the sensitive value from the environment entirely, so systems that only ever see tokens fall out of compliance scope.
Agentless, Data-Centric Protection for IBM Z
DataStealth operates inline with network traffic to tokenize sensitive data as it moves from the mainframe to cloud and SaaS environments, discovering, classifying, and protecting data without installing agents on z/OS, modifying COBOL applications, or impacting mainframe performance.
Proven at Scale
National Telecom
Secured IBM DB2 databases and live TN3270 sessions with zero code changes.
Global Insurer
Protected non-production environments while maintaining developer velocity.
Engineered for Mainframe Constraints
Quantum-Resistant by Design
Tokens carry no mathematical relationship to the original data, so there is nothing for an attacker (quantum or otherwise) to compute against.
Deploy in Hours, Not Months
Network-layer insertion scopes the change to the network path rather than to mainframe applications, which typically shortens the change window and reduces mainframe overhead.
