Agentic Cyber Defence

A fleet of Cyber AI Agents that never stand down

Specialised autonomous agents reason, collaborate and act on your behalf, investigating every alert, hunting silently, and responding the moment a threat appears. Your analysts move from triage to command.

The fleet

Purpose-built autonomous agents

Each agent masters one mission and coordinates with the others through the NEXUS graph.

Sentinel Agent

Watches every entity 24/7, scoring anomalies and raising only what truly matters, eliminating alert fatigue.

Analyst Agent

Auto-investigates each incident end-to-end, building a complete, explained narrative in seconds.

Hunter Agent

Proactively pursues adversary infrastructure and TTPs across your estate and the open internet.

Responder Agent

Executes surgical, proportionate containment in milliseconds, with calibrated autonomy and full audit.

Recon Agent

Maps your external attack surface and exposed assets the way an adversary would, then prioritises the fix.

Briefing Agent

Translates technical activity into executive- and command-ready situational reports on demand.

How they work

From alert to action, autonomously

Perceive

Agents draw on the self-learning AI and the NEXUS graph to maintain real-time awareness of every asset, identity and signal.

Reason

Each agent plans across multiple steps, correlating evidence, weighing intent, and choosing the minimal effective action.

Collaborate

Agents hand off tasks to one another, Sentinel to Analyst to Responder, orchestrated through a shared mission state.

Act & Explain

Action is taken at machine speed and every decision is logged in plain language for human oversight and assurance.

Human command, machine execution

Your people set intent. The agents do the work.

Cyber AI Agents are governed by policy you control. Set the autonomy level per agent, per environment, from "recommend only" to "self-driving", and adjust at any time. Humans stay firmly in command of the mission.

  • Policy-bound autonomy with guardrails and approvals.
  • 10× analyst leverage, automate triage, free experts for strategy.
  • Always-on coverage across every timezone and every shift.
Cyberium
Secured by design

Autonomous, and accountable

Agentic AI introduces new attack surface. Cyberium treats agent security as a first-class discipline, aligned to the emerging standards for AI risk.

MCP & Tool Security

Hardened Model Context Protocol surfaces and tool calls, agents can only reach what policy permits.

Autonomy Control

Calibrated autonomy per agent and environment, with guardrails, approvals and instant override.

🔑

Machine Identities

Every agent runs under a governed machine identity, scoped, rotated and fully attributable.

AI Red Teaming

Continuous testing against prompt injection, data leakage and model abuse, PyRIT, Promptfoo, Giskard and more.

Aligned to OWASP LLM Top 10, MITRE ATLAS, NIST AI RMF and ISO/IEC 42001, with EU AI Act anticipation.
