The traffic that costs you before you notice it
Each use case below is a different shape of automated traffic. The evidence and response change with the route, the client, and the policy you need to enforce.
Scraping and AI crawlers
Protect content, catalogs, and application data without blocking every crawler. Start by checking which scraping tools can retrieve your pages, then choose controls that preserve approved access.
Account takeover
Credential-stuffing tools can replay exposed username and password pairs at scale. The login still needs its normal authentication and account-security controls.
Checkout and carding fraud
Automated card testing can repeat payment attempts through a valid checkout flow. Bot evidence adds context before the payment provider makes its own fraud decision.
Promo abuse and multi-accounting
Automated sign-up flows can rotate submitted details and browser profiles. Bot evidence helps enforce an offer policy without claiming to resolve a person's identity.
SMS pumping
Every verification code a site sends by SMS costs money. SMS pumping scripts request codes in bulk to numbers that earn the fraudster a share of that cost. Centinel evaluates the request that asks for the code, before the message is sent.
API abuse
Mobile apps, partner integrations, and backend services may call an API without loading a page. Those requests need a policy built from the evidence the server integration actually receives.
DDoS and traffic floods
Aggressive crawlers and distributed automation can consume application capacity. Centinel complements rather than replaces volumetric DDoS protection.
