Push Security

30 mentions across 3 sources · 51% positive — mixed (weighted across 3 sources)

Hacker News, YouTube, Lemmy

What users praise

  • • Browser-extension delivery means no endpoint agent and no forced enterprise-browser migration
  • • Cross-browser coverage including Chromebooks and AI/enterprise browsers
  • • Published $5/user/month Standard pricing with self-serve trial lowers evaluation friction
  • • Detections target modern browser-layer threats: AiTM, ClickFix, BitB, device-code phishing

What frustrates them

  • • Essentially no independent user reviews anywhere in the scraped community data
  • • Extension-based security is itself a supply-chain risk that HN commenters flag
  • • Clipboard, prompt and file-upload monitoring raises privacy and data-residency objections
  • • Autonomous agent deployment of blocks may conflict with change-control processes
