The real-time, unified alternative to Unit21
Unit21 gives risk and compliance teams rules, models and strong case management. Omniguard shares that rules-plus-AI philosophy, adds real-time scoring at the edge, and lives in the same platform as your application security.
Two different models
Unit21 is a risk and AML platform combining rules and models with strong case management, aimed at fraud and compliance operations teams.
Nemesis Omniguard scores every transaction and account event in real time, fusing your rules with advanced AI models into one explainable risk score (allow, review, or block). Every decision ships with the exact signals that drove it and an AML/KYC case trail, inside the same platform that protects your app, API and LLM.

Questions
Is Nemesis Omniguard a Unit21 alternative?
Yes. Both score transaction and account risk. Omniguard's difference is that it fuses your rules with AI models into one explainable score, returns a real-time allow/review/block with the exact signals behind it, and sits inside the same platform that protects your app, API and LLM, so fraud and application security share one view.
Can Nemesis Omniguard replace or sit alongside Unit21?
Either. You can run Omniguard as your primary transaction-risk engine, or alongside Unit21 while you migrate. It exposes a simple real-time scoring API and a review/case workflow, so it drops into an existing stack.
Does Omniguard use rules or AI?
Both, on purpose. It fuses your business rules with advanced AI models into a single risk score, so you keep the rules you trust and the models catch the coordinated fraud rings that no static rule was written for. Every decision is explainable, down to the signals that drove it.
