The Browser Is Healthcare’s Biggest Security Blind Spot

Healthcare runs in the browser. EHRs, claims, and patient data get pasted into web forms and AI tools. That’s where the attacks land. Credential phishing, session theft, and browser-delivered ransomware slip past the SWG, EDR, and DLP you already run, because none of them see inside the browser session.

Menlo’s Q1 2026 healthcare telemetry shows the scale of the gap:

• 58% of healthcare attacks are credential phishing and the browser is where they arrive
• 35% of the evasive threats Menlo blocked came from domains already deemed ‘safe,’ including Epic, Cerner, and Change Healthcare
• 1 in 5 phishing links went completely undetected by legacy URL filtering
• More than 276 million patient records were compromised in 2024 alone
