PK Protect: mainframe modernization
Data exposure and compliance risks increase as data is moved, copied, and restructured during mainframe modernization initiatives. PK Protect discovers where critical z/OS data lives and protects it throughout your modernization journey.
Trusted by leading organizations for over 40 years
























Secure and compliant mainframe modernization
Modernization is essential to keep up with rapidly changing IT landscapes. But it introduces risk as sensitive z/OS data moves into new environments. PK Protect automatically discovers application data and critical data elements, so you know exactly what you’re migrating. With persistent encryption that stays with data in and out of z/OS, our platform reduces risk and ensures compliance as you modernize.
Why PK Protect
End-to-end security for mainframe digital transformation
Improve z/OS data visibility
Mainframe modernization requires uncovering data that has accumulated over decades. Our solution shows where sensitive data resides and how it’s used across systems. Automated discovery of application data, critical data elements, and processes helps you identify vulnerabilities before you move workloads and data.
Prevent data leakage
z/OS production data can be exposed as it moves to development, test, cloud, analytics, or AI environments. PK Protect discovers and secures metadata and sensitive elements before migrations to reduce risk. With persistent encryption that travels with your data, our mainframe modernization solution protects data in motion, at rest, and across downstream systems.
Streamline compliance
Modernization often triggers new compliance obligations. Our solution automatically generates SBOMs and provides metadata intelligence to satisfy regulatory requirements. Pass audits, avoid fines, and prevent compliance gaps as you modernize.
Avoid fines when modernizing
A major U.S. financial institution used PK Protect to gain deeper visibility into data in z/OS during a modernization initiative. After scanning 504 million VSAM records, they uncovered 422 million credit card numbers and 450 million Social Security Numbers within unprotected datasets. This proactive data security effort helped the organization avoid an estimated $150 million in regulatory fines.
What you get
Features to enable safe mainframe digital transformation
Accurate discovery
z/OS datasets often contain unstructured, binary data with no field headers. This makes manual mapping of data time consuming, especially with skills shortages across mainframe teams. PK Protect ingests application data definitions and copybooks to locate sensitive mainframe data quickly and accurately. Eliminate manual processes and ensure clear visibility to support modernization.
Persistent encryption
Data on the mainframe is encrypted, but what happens when the data moves, such as during cloud migrations? Transfer protocols secure data in transit but data is exposed when it reaches new environments. PK Protect applies persistent encryption that stays with your data in and out of z/OS. This reduces risk and secures data across every platform.
