What Every Financial Services CIO Needs to Know About Mainframe Compliance

1 min. read

Every day, your mainframe processes transactions worth trillions of dollars. But here's what most Financial Services CIOs don't realize: terminal emulation and green-screen access can't meet the security requirements of DORA, PCI DSS 4.0, and NYDFS regulations that are already in effect.

The challenge? Most organizations don't even know how these regulations apply to their mainframes.

 

Three new regulations targeting mainframe security

  • DORA (active now) - Maximum 2-hour recovery time, mandatory MFA
  • PCI DSS 4.0 (active now) - Enhanced validation, stricter payment data protection
  • NYDFS 23 NYCRR Part 500 (final deadline Nov 2025) - Industry-standard encryption, no compensating controls

This whitepaper breaks down what each regulation actually means for your mainframe environment and provides a strategic framework for addressing compliance gaps.

 

What financial services CIOs will learn:

  • Specific compliance requirements for all 3 regulations
  • Step-by-step implementation strategies
  • Common mistakes that trigger penalties
  • Modern solutions that actually work
