Cybersecurity Challenges in 2025

The Changing Cybersecurity Landscape in 2025

Navigating compliance with the new PCI DSS, CMMC, and HIPAA Security Rule

Looming compliance deadlines, relentless cyberthreats, and a shifting regulatory landscape have combined to make 2025 a challenging year for cybersecurity.

While the effects of an evolving regulatory climate are yet to be determined, here’s what we know about impending security updates from the payment card industry (PCI DSS 4.0.1), the Department of Defense (CMMC 2.0), and the HHS Office for Civil Rights (HIPAA Security Rule).

• CMMC 2.0 and the new HIPAA Security Rule represent updates to previous versions of these federal security regulations; PCI DSS 4.0.1 is an update to the industry’s previous security standard.
• All three of these security updates have key implementation milestones in 2025.
• PCI DSS 4.0.1 addresses formatting and typographical errors discovered in v4.0 and provides additional implementation guidance for users, with minimal changes to the existing security requirements of v4.0.
• CMMC 2.0 significantly streamlines security requirements to three levels of cybersecurity, aligns the requirements at each level with well-known NIST cybersecurity standards, and relieves the smallest contractors of unnecessary compliance burdens.
• The new HIPAA Security Rule aims to further strengthen cybersecurity safeguards for electronic protected health information, or ePHI, in the most substantial healthcare security update in more than a decade.
