SonicWall today released its 2026 Healthcare Protect Brief, a vertical-specific companion to the SonicWall 2026 Cyber Protect Report, revealing that healthcare cybersecurity remains the most persistently targeted industry in SonicWall’s global telemetry, and that the gap between healthcare and every other sector is widening, not closing.
While attack volumes across most verticals declined between 17% and 56% year-over-year, healthcare recorded the smallest decline of any tracked industry. The finding is not simply that healthcare is heavily targeted – it’s because attackers are less willing to leave healthcare than anywhere else.
“Healthcare is the most targeted industry for several reasons, and none of them are accidental,” said Michael Crean, SonicWall SVP of Managed Services. “What our research makes clear is that attackers have done the math. Hospitals cannot go dark, downtime is measured in patient outcomes and the pressure to pay is unlike anything in any other sector. None of that changes until healthcare stops relying on security architectures built for a world that no longer exists, and starts treating Zero Trust not as a future initiative, but as the baseline they needed yesterday.”
SonicWall’s Healthcare Protect Brief draws on data from SonicWall’s global network of more than one million security sensors to document the specific attack patterns, exploitation vectors and ransomware campaigns defining the healthcare threat landscape in 2026.
Key Findings from the 2026 SonicWall Healthcare Protect Brief
- Healthcare recorded the smallest attack decline of any tracked vertical, just 17% year-over-year
- UltraVNC buffer overflow attacks generated 13.3 million hits in five months, a finding unique to healthcare
- IoT exploitation spanned 243 unique attack signatures targeting connected medical devices
- Ten active ransomware families operated simultaneously against healthcare – more than any other vertical
- Log4j generated 11.4…
