Cortex Labs helps organisations harness the power of AI without compromising confidentiality. As generative AI becomes essential to competitive advantage, security-conscious organisations face a difficult choice: fall behind competitors who are using AI, or risk exposing sensitive data to third-party providers. We solve that problem. Our platform gives teams access to world-class AI models through a secure, modular system designed for organisations that cant afford data leakage, from SMEs with sensitive IP to organisations in defence, intelligence, government, and regulated industries. Whether you need confidential access to frontier models, intelligence from your own internal knowledge, or a fully air-gapped deployment you control completely, Cortex delivers AI that works for your business, not against it. What we offer: → Cortex Chat – Secure AI interface with access to the latest models → Cortex Connect – Turn internal knowledge into actionable intelligence through AI agents that analyse, visualise, and generate rich reports → Cortex Connect+ – Build custom pipelines to ingest, enrich, and automate your most complex data workflows → Cortex Shield – Three tiers of security, from enhanced attribution protection to complete air-gapped sovereignty Our founding team brings backgrounds in military, intelligence, and privacy technology—including a patent in advanced cryptographic privacy. We built Cortex because we understand whats at stake when sensitive information meets AI.
