Automated analysis engine that ingests voice traffic data across operator deployments, detects fraudulent prefix patterns at scale, and generates ready-to-deploy blocking recommendations, replacing manual analyst review entirely. Delivers consistent, repeatable detection across all deployments with configurable threshold settings. Includes a startup automation script for scheduled, unattended runs.
Automated SBDX spam classification and blocking rule generator. Processes mixed, unlabeled Excel exports from SBDX, classifies senders as SPAM or HAM, and produces ready-to-apply blocking recommendations, removing the most time-intensive step from the analyst review workflow.
Monthly FCDX Champions program dashboard that consolidates team metrics, live deployment status, achievements, challenges, and action items into a single executive-ready visual interface.
Data that used to require minutes of digging across Confluence pages, slides, and documents is now available in a single click. Replaced scattered manual updates and PowerPoint slide decks entirely.
PingOcean's Excel export is broken — only PDF works, leaving analysts with raw, unusable output. This tool parses both PDF and Excel PingOcean penetration test reports, reconstructs structured data, auto-generates Gatekeeper-ready IDP prefix blocking rules (configurable 4–8 digit length), and renders 4 intelligence charts: Brands Penetrated, Voice Leakage Source Countries, OTT Channel Breakdown, and Test Results Distribution.
