Accedia AI Fraud Detector for Banks & Fintechs


Cut false positives by 80% and auto-resolve 95% of clear-cut alerts. The Accedia AI Fraud Detector scores every transaction, explains every decision, and routes only the real threats to your team. Built for fraud operations at banks and fintechs who answer to DORA, FCA, and their own bottom line.

What is the Accedia AI Fraud Detector

The Accedia AI Fraud Detector is a machine learning-powered solution that replaces static rule-based fraud systems with probability-based risk scoring. It evaluates every transaction alert across multiple behavioural and contextual factors, assigns a clear risk category (Low, Medium, or High), provides audit-ready reason codes explaining each decision, and automatically routes cases to the right queue. The system is designed for banks, fintechs, and payment processors that need to reduce false positives, catch more genuine fraud, and satisfy regulatory requirements for model explainability.

Why Rule-Based Fraud Systems Fail

With AI-enabled fraud projected to hit $40B by 2027 (Deloitte), your fraud team faces an impossible trade-off. Catch more threats and you drown in false alerts. Reduce the noise and real fraud slips through. For banks and fintechs, compliance pressure is real (DORA, PSD3, FCA), and regulators expect you to explain how decisions are made. A model that works but can't be explained is a liability, not an asset.

  • Missed fraud costs you in chargebacks, remediation, and regulatory scrutiny

  • Investigators waste hours on low-risk transactions while high-risk cases sit in queue

  • Black-box models make auditors nervous and regulators ask questions you can't answer

  • Legacy rule-based systems can't keep up with evolving fraud patterns


  • Every false decline frustrates a legitimate customer and costs you revenue

  • Manual triage doesn't scale, and hiring more analysts isn't a sustainable fix


How the Accedia AI Fraud Detector Works

  • 1

    Evaluate alerts with ML

    Every transaction gets a fraud probability score (0–1) based on multiple factors, not binary rule triggers. The model detects patterns that static rules miss.

  • 2

    Assign a clear risk category

    Transactions are classified as Low, Medium, or High risk. You define the thresholds. You set the risk appetite. The model executes it.

  • 3

    Explain every decision

    Every decision is audit-ready. Reason codes show exactly which factors contributed and by how much, in language regulators and auditors can follow.

  • 4

    Route to the right queue

    Low-risk cases auto-approve. High-risk cases escalate immediately. Your analysts spend time where it counts, not chasing noise.

What You Get Out of the Box

  • Advanced Pattern Detection

    Our model is trained to work with large datasets and detect relationships beyond obvious transaction attributes, catching patterns that static rules miss.

  • Explainable AI Outputs

    Every score comes with human-readable reasons showing what influenced the outcome. This gives your governance team, auditors, and board the transparency they need to trust the system.

  • Auto-Decision Engine

    96%+ of clear-cut cases are handled without analyst intervention. Your team focuses on cases that actually need human judgment.

  • Real-Time Risk Dashboard

    Full visibility into workload, exposure, accuracy, and fraud distribution. Metrics ready for audit reviews and board reporting.

  • Configurable Thresholds

    You define what triggers auto-approval, manual review, or auto-decline. The model adapts to your risk appetite, not the other way around.

  • Integration-Ready Architecture

    REST API connects to your existing fraud platform. Supports real-time and batch processing. PoC deployment in in 8 weeks.

    AI Fraud Detection for DORA and FCA Compliance

    DORA (Digital Operational Resilience Act), in force since January 2025, requires financial entities to establish automated monitoring systems that detect anomalies and trigger alerts within hours. The FCA expects firms to explain how AI models reach decisions, particularly in fraud detection. The AI Fraud Detector meets both requirements by design. Every decision includes weighted reason codes, every alert has a full audit trail, and the system supports the incident detection and classification protocols that DORA mandates.

    AI Fraud Detection FAQ

    • What is AI-powered fraud detection?

      AI fraud detection uses machine learning to score transactions on fraud probability (0–1) rather than relying on static rules. The model analyses multiple factors simultaneously, catches patterns individual rules miss, and explains why each transaction was flagged. This approach reduces false positives while improving catch rates.

    • How does AI fraud detection reduce missed fraud?

      The model analyses patterns across multiple transaction attributes simultaneously, catching fraud signals that individual rules miss. It scores every transaction on probability (0–1), so high-risk cases are flagged before they slip through.

    • Can we explain AI decisions to regulators?

      Yes. Every risk score includes weighted reason codes showing which factors contributed and by how much. This supports DORA, PSD3, FCA expectations, and aligns with ISO 42001 and EU AI Act explainability requirements.

      Read our AI governance checklist
    • How long does integration take?

      Typical PoC deployment takes 4–8 weeks, depending on data access and workflow complexity. The solution connects via REST API to your existing fraud management platform.
