Simplify efficient and secure exchange of mainframe files
across the Enterprise and beyond.

Transport & Storage

Average compression of 85% to 95% reduces transmission time, bandwidth usage, and storage requirements by the same factor. CRC-Checking certifies that data delivered is complete and accurate.

Data Protection

AES ZIP Password Encryption and PGP file support keep data protected in transit and at rest. Compatible with GZIP, WinZip, 7-ZIP, and PKZIP/SecureZIP. EBCDIC/ASCII translation included.

Regulatory Compliance

Certified encryption algorithms directly address SARBOX, GLBA, PCI DSS, HIPAA, and FIPS compliance mandates — with no additional tools required.

CICS & Batch Compression/Encryption Programmer API

Our CICS and Batch compression and encryption programmer API offers a powerful, easy to implement, solution for in-memory compression and/or encryption of data within your mainframe.

The API provides a seamless integration with your existing CICS and Batch applications, allowing you to compress/decompress and/or encrypt/decrypt data streams (e.g., passwords, credit card numbers, social security numbers, entire records, etc.) on-the-fly without impacting performance.

The use of industry standard deflate/inflate compression and hardware assisted (CPACF) FIPS 197 certified AES encryption algorithms ensures your data is not only secure, but also easily sharable across different systems and platforms. If you are looking to comply with data privacy regulations or simply want to enhance the efficiency and security of your mainframe applications, our CICS and Batch Compression/Encryption Programmer API may be the ideal solution.
