At renewal, SentinelOne may require purchasing additional SKUs that were not part of the original contract, even if you don't use them.

We are in process of renewing SentinelOne for 250 seats, and they want to cram in an $800 line item we won't use, saying it's required for all new renewals.

Example: True Cost for 25 Users

License (25 × $8.25 × 12) $2,475/yr
Cloud Funnel for SIEM Integration +$1-2/endpoint/month
Extended Data Retention +5-15% of license costs
Forced Renewal Add-ons +$800-1000 per renewal
Estimated Year 1 Total ~$2,578
That's roughly 1.0× the advertised license price. The median SentinelOne contract is $99/yr across Vendr purchases.
