Sensfrx

Sensfrx is an AI-driven fraud-detection layer for SaaS and e-commerce sites that scores every login, signup, and transaction in real time using device, location, and behavioural signals. The DealMirror lifetime deal swaps a per-event SaaS bill for a one-off purchase covering multi-domain deployment, custom rules, sandbox testing, and a single dashboard for every fraudulent event you would otherwise stitch together from logs.

What Sensfrx actually does

It sits between your sign-up flow, login screen, and checkout, and returns a fraud score for each event before that event is allowed to complete. The engine combines device profiling, IP and geo signals, behavioural fingerprints, and email and phishing checks — 200+ smart signals in total — then applies whatever custom rules you have set on top.

• Real-time scoring of signups, logins, and transactions
• 200+ device, location, and behaviour signals built in
• Custom rules plus blacklist and whitelist controls
• Sandbox mode for testing rules before production
• Multi-domain support under a single account
• Unified dashboard for chargebacks, ATO, and bot activity

How it fits in your stack

Sensfrx slots in alongside hosted fraud tools like Sift, SEON, or Stripe Radar, except the pricing flips: instead of paying per scored event each month, you pay once and pipe as many events through the API as you want. The trade is operational — hosted incumbents come with a fuller managed-rules library out of the box, while Sensfrx hands you the rules engine and asks you to tune it. For teams that already think in fraud signals, that is a feature.

Who it's built for

SaaS founders losing trial budget to fake signups, e-commerce shops bleeding margin to chargebacks, and small platforms watching credential-stuffing attempts climb in their logs. If your monthly fraud-tool invoice already runs in the high three figures, the lifetime deal pays back inside a quarter; if you currently have no fraud layer at all, the upgrade from nothing to real-time scoring is the bigger win.

Common use cases the platform handles: new-account fraud and fake registrations, account takeover and credential stuffing, fake or abusive orders, transaction fraud including stolen-card use, free-trial abuse, loyalty and promo-code abuse, and bot or spam attacks. One opinion: the sandbox-then-deploy workflow is the feature most teams under-use, and the one that separates a fraud tool from a noisy alert firehose.
