Defending your wireless airspace, beyond the network perimeter

In 2019, we pioneered the world’s first solution capable of accurately detecting and locating cell phones just by their cellular signal. Five years later, Bastille has evolved into a comprehensive wireless airspace defense platform that detects a vast spectrum of wireless devices, networks, and threats typically overlooked by Zero Trust, CAASM and XDR programs.

Bastille goes beyond the traditional

From RF-based malicious hacking tools to unauthorized wearables and IoT in corporate and government spaces, Bastille goes beyond the traditional network perimeter to address an expanding enterprise attack surface brought on by the rise of AI, intricate multi-cloud environments, and flexible corporate device policies.

Today Bastille helps Fortune 100 and government organizations evolve and enforce their wireless policies in the face of 24 billion wireless devices inside and outside their organizations. With 34 patents and more pending, our sophisticated AI models identify and protect against more wireless threats than any other platform on the market.

Enterprise-grade technology, federal-grade security

Bastille brings deep wireless threat expertise, stringent compliance guardrails, and patented AI location and assessment technology onto a single enterprise platform. Deploy quickly and cost-effectively using our API-led architecture and real-time, augmented data streams that integrate into your existing ecosystem.

Bad actors love to find the one area you’re not watching closely enough. Bastille closes one of your most vulnerable gaps by strengthening your cybersecurity posture with real-time location data, device metadata, user behavior, and more, all within the frameworks and policies you’ve worked so hard to implement.
