Our Platform: CastleGuard AI
CastleGuard AI is Nextria’s flagship intelligence platform – a secure, AI-powered system that ingests and analyzes unstructured data from any source to deliver actionable insights. From open-source intelligence to classified reports, CastleGuard fuses data into a unified picture, leveraging advanced large language models (LLMs) for natural-language querying and analysis.
It’s an intelligence platform built for the realities of defense and security, where every second and every snippet of information counts.

Problems we Solve
Multi-Source Intelligence (OSINT, HUMINT, SIGINT)
Ingest and correlate data from open sources, human reports, and signals intelligence into one cohesive knowledge base. CastleGuard AI breaks down silos so nothing is overlooked.
AI-Assisted Analysis (LLM-Powered)
Use cutting-edge large language models to sift through documents and databases. Analysts can ask natural-language questions and get immediate answers, enabling quick discovery of critical facts hidden in reports.
Automated Translation
Instantly translate documents and communications in foreign languages. CastleGuard’s built-in translation engine ensures language barriers don’t slow down your intelligence cycle.
Interactive Visualization
Turn complex data into clear visuals – from link analysis charts to geospatial maps. Identify patterns and connections at a glance, and pivot views to explore the data from different angles.
Seamless Integration & Export
Easily integrate CastleGuard AI with your existing workflows. Export intelligence insights to tools like IBM i2 Analyst’s Notebook or Esri ArcGIS with one click, so you can further analyze or share results in familiar formats.
Secure Deployment
Deploy on your terms – whether within a accredited cloud enclave or entirely on-premise behind your firewall. CastleGuard AI was built to meet classified security requirements and maintain full data sovereignty for our clients.
