Signals that should not be touched
Decoys, including credentials and sensitive paths, create clear tripwires around cloud, identity, application, web, and network environments.
Cyber deception and active defence
Catch attackers, human or AI, before they reach real systems.
FIRCY Sense places realistic decoys across your cloud, identity, endpoints, applications, and networks. When an attacker, automated tool, or AI agent touches one, you get a high-confidence early warning and a clear path to defensive action through the tools you already use.

Cyber deception in practice
Every attacker has to explore before they strike.
FIRCY Sense makes sure the first thing they touch is a decoy. Realistic decoys, including decoy credentials and sensitive paths, sit around the environments that matter. Legitimate users have no reason to touch them, so an interaction is a high-confidence signal worth investigating, not more noise.
When something does interact, the result is not another generic alert. FIRCY captures the evidence and helps your team understand what was touched, which path was used, and where to respond next.
Evidence for analysts
Suspicious interaction can include useful context such as source details, paths followed, artefacts touched, timestamps, and behavioural clues.
Works with your existing stack
Detections can be routed into SIEM, SOAR, EDR, ticketing, WAF, cloud, collaboration, and custom response workflows.
Cyber Deception, Active Defence, and Early Warning
Get early warning. Understand faster. Respond with confidence.
FIRCY Sense helps security teams uncover meaningful adversary activity earlier, turn it into high-confidence threat intelligence, and route it into operational response workflows.
AI agents operating outside their task
Make suspicious interactions with decoy credentials, documents, APIs and MCP surfaces visible. Investigate activity involving unknown automation or approved agents operating outside their intended workflow.
AI-agent security
An approved agent can still take an unauthorised action.
Approval to use an AI tool is not approval for every action it can take. FIRCY Sense adds controlled decoy touchpoints around selected workflows, helping your team investigate unexpected access or attempted credential use. Correlate the interaction with available identity and application context before deciding how to respond.

Why FIRCY Sense
Deception that doesn’t stop at the alert.
Unlike generic threat feeds, FIRCY Sense intelligence comes from real activity against your own environment. Unlike passive deception tools, it connects detection directly to investigation and active defence.
Generate intelligence from real adversary activity
Capture indicators, source details, paths, timings, and behavioural evidence directly from suspicious interaction instead of relying only on generic external context.
Deliver intelligence where analysts already work
Make detections and contextual intelligence available through dashboards, API access, SIEM, SOAR, EDR, ticketing, and broader threat intelligence workflows.
Add early warning to the security stack you already have
FIRCY Sense complements the tools you already use, with no rip-and-replace. High-confidence alerts and contextual intelligence flow into security operations, investigations, and response workflows. Security teams get clearer signals and faster answers. Leadership gets earlier warning and less risk.
