The short version

  • 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; TunnelBear free plan's data cap is small compared to competitors offering more generous free allowances.
  • They diverge on capability: Microsoft Sentinel covers AI-powered analytics, TunnelBear covers Encrypted VPN tunnel.
  • 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

TunnelBear

  • Free plan's data cap is small compared to competitors offering more generous free allowances.
  • Lacks advanced features like dedicated IP addresses or split-tunneling controls found in some rival VPNs.
  • Server network is smaller than large competitors like NordVPN or ExpressVPN.
  • No standalone router-level app, limiting whole-network protection options.
