Sophos Intercept X
Cybersecurity
Advanced endpoint protection with deep learning
- From
- $28/year
- Rated
- -
The short version
- Only Microsoft Sentinel has a free tier, so it costs nothing to try first.
- Each has a real cost: Microsoft Sentinel billing is driven by the volume of log data ingested per day, so cost scales with log noise rather than with users or protected assets; 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: Microsoft Sentinel covers AI-powered analytics, 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.
Microsoft Sentinel
- Billing is driven by the volume of log data ingested per day, so cost scales with log noise rather than with users or protected assets
- Commitment tier discounts require reserving daily ingestion capacity in advance, and a tier cannot be downgraded until 31 days have passed
- Commitment tiers start at 100 GB per day, above what smaller estates ingest
- Charges for Log Analytics, Logic Apps and Machine Learning are billed separately on top of Sentinel itself
- The free allowance is only up to 5 MB per user per day for selected Microsoft 365 security logs
- Promotional commitment pricing is time limited and locks in only until a stated end date
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
