Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Sophos Intercept X

  • Sophos publishes no price for endpoint protection: the product page names editions but gives no per user rate, no minimum seat count and no contract length, and routes buyers to a sales enquiry
  • Extended detection and response requires the Advanced with XDR edition rather than the base endpoint product
  • 24x7 monitored detection and response is sold as the separate Sophos MDR service on top of the endpoint licence
  • The Intercept X name has been retired in favour of Sophos Endpoint, so older documentation refers to a brand the vendor no longer uses

Tenable

  • Pricing starts at $3500/year for Tenable One VM, expensive for small organizations
  • Many enterprise features require custom quote and sales engagement
  • Cloud Exposure, OT Exposure, and other modules have no published pricing
  • Multi-year contracts common, limiting flexibility
  • Setup and configuration complexity for enterprise deployments
