The short version

  • Only Arnica has a free tier, so it costs nothing to try first.
  • Each has a real cost: Arnica per-identity pricing ($25-$50/person/year) requires tracking active developers; 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
  • They diverge on capability: Arnica covers AI SAST, Sophos Intercept X covers Deep learning AI.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Arnica

  • Per-identity pricing ($25-$50/person/year) requires tracking active developers
  • Overage identity tracking via 90-day PR activity can be unpredictable
  • Free plan limited to weekly updates, requiring upgrade for real-time scanning
  • Advanced add-ons (Image Scanning, AI SAST, Agentic Rules Enforcer) pricing not published
  • On-premises deployment limited to Enterprise tier

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
