Gartner Urges Blocking AI Browsers Immediately
Gartner warns customers that AI browsers pose major cybersecurity risks and should be blocked for the foreseeable future. The advisory defines AI browsers as those with an AI sidebar and agentic capabilities, names examples including Perplexity Comet, Opera Neon, and ChatGPT Atlas, and warns of prompt-injection and credential-exfiltration risks; it says understanding risks will take "years, not months" and urges CISOs to block these browsers.
Key Points
- 1Warns to block AI browsers with agentic automation and AI sidebars exposing web sessions
- 2Identifies prompt-injection and cloud data exfiltration as primary risks leaking credentials and secrets
- 3Urges CISOs to block agentic browsers, control fleet usage, and restrict credential sharing
Scoring Rationale
Gartner's authoritative, actionable guidance drives broad enterprise response; limited by the emerging, unevenly tested technology.
