Forter is the enterprise gold standard for e-commerce chargeback prevention with chargeback guarantees on approved transactions. It targets large merchants, takes weeks to integrate, and prices in the high four to six figures monthly. Sentinel covers the same fraud vectors via API in under a day, with no minimum spend.

What is Forter?
Forter is an enterprise-grade e-commerce fraud platform offering automated decisioning on every transaction with chargeback liability shift on approvals. Founded in 2013, Forter is deployed at Nordstrom, ASOS, Priceline, and similar large merchants. It combines transaction-time behavioral analysis, post-checkout monitoring, and a network-effect fraud graph across all Forter customers.
- Chargeback liability guarantee on approved transactions
- Cross-merchant fraud graph (network effect at scale)
- Mature for enterprise e-commerce (10k+ orders/day)
- Fully automated decisioning — no manual review queue to staff
- Strong integrations with major commerce platforms
- Enterprise-only pricing — entry tier lists at $120k/year (~$10k/month) on AWS Marketplace, not viable for SMB
- Sales-led integration typically takes weeks (custom contracts, kickoff meetings, scoping)
- Black-box decisioning — limited visibility into which signals fired
- Built around digital commerce — limited fit for SaaS and gaming; fintech/PSPs are served via a separate Forter Element product
- No public free tier or self-serve signup
Free tier: 1,000 requests/hour. No card, no expiry. Growth at €49/mo (founding price); enterprise by agreement.
Custom enterprise contracts only. Forter’s AWS Marketplace listing starts at $120,000/year (under 1M decisions/year) with per-decision fees on top; direct quotes are custom. No published price list on forter.com.
When to use Forter, when to use Sentinel
- You’re a $50M+/year e-commerce merchant who wants chargeback liability transferred and has procurement bandwidth for a multi-week integration.
- You’re below Forter’s enterprise floor (under ~$10k/month fraud spend)
- You want self-serve signup and integration in under a day, not weeks
- You need detection beyond e-commerce (SaaS signups, fintech KYC, gaming accounts)
- You want transparent signal-by-signal verdicts instead of a black-box score
- You don’t want to commit to enterprise procurement before validating value

Frequently Asked Questions
Can Sentinel replace Forter?
Sentinel can replace Forter for the detection layer if you don’t need the chargeback liability guarantee. Forter’s pricing is justified mostly by that guarantee — they assume the financial risk of approved-but-fraudulent transactions. If your chargeback rate is low enough that you’d rather keep the liability and save 90% of the cost, Sentinel’s detection covers the same vectors at a fraction of the spend.
Why is Forter so expensive?
Forter prices in the chargeback liability they assume. When they approve a transaction that turns into a chargeback, Forter eats the cost. That’s expensive insurance, and only makes sense at high transaction volumes where the math works in your favor. Below ~$10k/month in fraud spend, the insurance premium typically exceeds the chargebacks you’d pay yourself.
Does Sentinel offer chargeback guarantees?
Not currently. Sentinel provides the detection signals; the liability for approved transactions stays with you. We are exploring partnership options with chargeback insurance providers — contact us if this is a hard requirement.
What does Forter do that Sentinel doesn’t?
Two things: chargeback liability shift on approved transactions, and cross-merchant fraud-graph data (Forter says over 200,000 businesses use its network). Sentinel does not offer these. We focus on real-time detection signals at a fraction of the price.
