A new report by Forescout reveals that the vast majority of medical devices lack support for post-quantum cryptography. Only 6% of internet-connected medical devices and 16% of medical operational technology are prepared for the transition, leaving critical healthcare infrastructure vulnerable as quantum capabilities advance.
Why it matters
Because healthcare data retains its sensitivity for decades, the current inability of these systems to upgrade presents a long-term risk. With quantum computers expected to crack existing encryption within five years, the slow adoption of new cryptographic standards threatens patient privacy and system security.
Researchers analyzed 2.5 million devices across 50 healthcare organizations, finding that just 31% of exposed systems currently support TLS 1.3. Standardized post-quantum cryptography requires specific Secure Shell (SSH) implementations and TLS 1.3, which many legacy medical devices cannot accommodate due to hardware limitations.

The details
Healthcare systems often feature extremely long hardware lifecycles, which complicates the implementation of new security protocols. To support post-quantum transitions, devices must utilize updated Secure Shell implementations—a network protocol used for secure remote login—and TLS 1.3, a transport layer security protocol that encrypts data over the internet. Currently, more than 5,500 internet-exposed systems that house sensitive electronic medical records lack these requirements.

The Tech Race
While traditional IT sectors have reached 50% compatibility with emerging post-quantum standards, the healthcare industry remains stalled at 6% for medical devices. This disparity marks a significant departure from the uniform adoption required to secure global infrastructure against impending quantum threats.
Healthcare providers relying on older medical equipment face a heightened risk of data exposure as quantum decryption technologies mature. Organizations must prioritize auditing their fleets for TLS 1.3 support, as most current medical devices will require significant hardware or software replacement to become future-proof.
The takeaway
The gap between standard IT equipment and medical technology security underscores the difficulty of patching specialized healthcare hardware. Stakeholders should monitor upcoming manufacturer firmware updates for any signs of post-quantum compatibility, as the five-year window for encryption hardening continues to narrow.
