Vital signs of cybersecurity: managing risk in healthcare

Healthcare organisations are expanding their digital footprint faster than traditional security processes can keep up. New cloud workloads appear overnight. Web-facing applications evolve constantly. Clinical devices, medical imaging systems, and third-party integrations create new internet-facing connections every day.

In this pace of change, one critical question remains difficult to answer:
What is actually exposed to the public internet?

Why this matters

Recent Censys research across a sample of healthcare organisations uncovered 500,000+ internet-facing assets, including vulnerable services, misconfigurations, revoked certificates, and publicly exposed medical systems. When visibility lags behind daily operations, risk becomes immediate. A forgotten web server, an abandoned cloud host, or a misconfigured vendor endpoint can serve as an entry point that disrupts clinical services and compromises patient safety.

Healthcare environments are becoming more complex. Decentralised operations, supplier-hosted systems, legacy infrastructure, and rapid digital transformation influence exposure.

Connected Health, the healthcare specialist of Wavelink and Censys, invite you to a practical session grounded in global internet-wide data and real-world healthcare insights.

 You will learn:

1. Why visibility gaps are growing in healthcare. Traditional tools such as VM, SIEM, CSPM, and endpoint protection only assess known assets. They cannot reveal exposures that fall outside controlled processes or originate from legacy environments.
2. How unknown or unmanaged assets create real exposure. Shadow IT, contractor-built systems, medical systems visible on the public internet, and supplier-hosted services all expand your external footprint. Real examples include open RDP, SMB, Telnet, and SNMP services observed across healthcare entities, as well as exposed EMR, PACS, and imaging systems.
3. Why Attack Surface Management (ASM) is now foundational. ASM provides continuous discovery, attribution, and prioritisation of externally facing assets across cloud, web, and third-party environments, essential when the internet’s attack surface changes by 15% daily.
4. How ASM enhances existing security investments. Integrating ASM insights into SIEM, VM, CSPM, IR, and governance functions creates a unified source of truth and improves cross-team risk prioritisation.
5. What regulators and boards now expect. Healthcare organisations are increasingly expected to demonstrate continuous awareness of external exposure, rapid response to emerging vulnerabilities (such as MOVEit, Ivanti, OpenSSH, Exim), and enhanced oversight of third‑party ecosystems.

Key Takeaway

Periodic discovery is no longer sufficient. Continuous, internet-wide visibility, supported by Attack Surface Management and the real-time insights of the Censys Internet Map, the world’s most comprehensive global scan dataset, is now the baseline for protecting patient care, sustaining operations, and maintaining trust.
