Where each one falls short

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

Blacksmith

  • Per-minute pricing model requires estimating usage to predict costs
  • macOS M4 pricing ($0.08/min) is significantly higher than GitHub Actions
  • Docker layer caching and sticky disks are paid add-ons at $0.50/GB/mo
  • Static IP add-on costs $100/IP/mo

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
