Adversaries are using AI to compress the gap between disclosure and active exploitation: not days, not hours—minutes. Meanwhile, proactive SOC workflows are still largely manual: when a threat advisory drops, analysts must read the advisory, assess relevance to your environment, check detection coverage, hunt for indicators, and recommend blocks. Each step depends on an analyst who's already juggling incident response, alert triage, and everything else.

An agentic defense model closes that gap—not by making analysts faster, but by augmenting them with a system that autonomously initiates, coordinates, and executes before the analyst has to.

That's what GreyMatter Agentic Teammates now do.

Semi- and Fully Autonomous Agentic Teammates

Agentic Teammates have always had autonomy. ReliaQuest customers prompted a Teammate in chat using natural language (“create a detection rule that detects when a new admin account is created in AWS”), and the Teammates interpreted their intent, planned, and executed the task.

With full autonomy, Agentic Teammates now continuously monitor telemetry, threat patterns, and operational signals across your environment. When they identify something actionable—a new threat advisory, a confirmed true positive, an emerging pattern—they plan and execute collaborative workflows with other Teammates without waiting for a prompt.

Teammate Workflows

Teammate Workflows are multi-step processes where Agentic Teammates execute end-to-end on a security objective. Workflows trigger upon environmental signals, on a defined schedule, or on demand—analysts can start a workflow to request a tuning report, identify risky users and assets, or surface patterns across historical incidents.

Example Workflow: New Threat Advisory

This prebuilt Teammate Workflow responds when a new threat advisory is published. The Threat Intel Analyst Teammate evaluates the advisory against your environment—your tech stack, existing detections, and threat exposure—drawing on patterns from 1,300+ customer environments to assess relevance. Depending on the relevance level, the necessary Teammates activate, then execute distinct actions while collaborating on the larger goal:

Threat Intel Analyst Teammate – Generates a personalized threat advisory report covering the threat actor profile, TTPs, affected assets, and recommended response actions, plus an executive summary for stakeholder reporting. For teams without a dedicated threat research function, this replaces the manual work of filtering advisory noise and synthesizing fragmented intelligence into environment-specific context.

Threat Hunter Teammate – Generates and executes a custom hunt package, searching your telemetry for indicators and behaviors associated with the advisory. Summarizes findings and provides remediation recommendations.

Investigation and Response Analyst Teammate – Proactively blocks malicious IOCs by executing respond playbooks across integrated technologies (e.g., blocking IP on firewalls or banning hashes with EDRs).

Detection Engineer Teammate – Identifies gaps in your current detection coverage relative to the advisory's TTPs and recommends custom detection rules or deploys them directly.

Configurable Automation Controls

When Agentic Teammates plan actions that directly impact your production environment—blocking an IOC, deploying a detection rule—those actions can pass through an optional Human-in-the-Loop (HITL) gate. You configure the gate: Tell the Teammates which actions require analyst sign-off and which can execute on their own.

When approval is required, recommendations surface as tasks within a GreyMatter Case. Analysts review the supporting context—why this indicator is flagged, what the rule change does—then approve or reject. Approved actions execute immediately; rejected actions are logged and closed.

Build Your Own Teammate Workflows

Customers can also build custom Teammate Workflows directly in GreyMatter Workflows. Three new workflow nodes let you:

  • Invoke a full teammate as a step in any workflow – Pass context from upstream nodes and the teammate operates with its full toolset

  • Send a prompt to an AI model and capture structured output for downstream steps – Extract IOCs, risk scores, rule specs, or any field your workflow needs

  • Trigger a specific teammate action—Run Hunt, Run Playbook, Create Detection Rule, or Deploy Detection Rule—with optional HITL gating for high-impact actions

GreyMatter Workflows already supports 10+ triggers—manual, event-based, or fired on alerts from other platform capabilities like Digital Risk Protection or Phishing Analyzer. A new Schedule Trigger adds time-based execution, turning weekly hunts, recurring gap analyses, and trend reports into automated routines.
