What is an agentic SOC?

An agentic SOC is a Security Operations Centre where AI agents autonomously triage, enrich and investigate security alerts — then hand a high-confidence recommendation to a human analyst who approves any destructive action. The agents reason about evidence step by step. They are not running fixed playbooks.

How an agentic SOC differs from SOAR and MDR

"Agentic SOC" sits between the two incumbent categories. SOAR is software that runs fixed playbooks. MDR is an outsourced human service. An agentic SOC is software that reasons — and keeps the human in the loop only where it matters.

Option A

SOAR

  • What it isSoftware that automates security workflows as a linear playbook.
  • Who decidesYou, the playbook author, at design time.
  • Fails whenReality doesn't match the YAML. Edge cases break the pipeline.
  • Best atDeterministic, well-bounded tasks: enrich, ticket, notify.
Option B — this page

Agentic SOC

  • What it isAI agents that reason about alerts, pick the next tool, and write narratives.
  • Who decidesThe agent during investigation; a human on destructive actions.
  • Fails safely whenIt hits a human-in-the-loop gate and waits.
  • Best atMessy, high-volume triage where every alert is slightly different.
Option C

MDR

  • What it isAn outsourced, human-led SOC service.
  • Who decidesA third-party analyst, reviewing your alerts.
  • Fails whenPriced per seat. Doesn't scale with UK MSP margins.
  • Best atClients who contractually require a named external SOC.
Architecture

What's inside an agentic SOC

Four layers, reading top to bottom. Each layer does one thing. Each decision is logged. A human gate sits at the bottom.

Layer stack

1
Intake  ·  Sentinel connector, Workspace connector, webhook listener
2
Reasoning swarm  ·  context.enrich → attck.map → ioc.enrich → lateral.scan → edr.query → privilege.check → timeline.build → risk.score
3
Narrative writer  ·  Generates the human-readable summary, MITRE ATT&CK citation, next-steps recommendation
4
HITL gate  ·  Session revoke / MFA reset / device isolate / tenant quarantine — waits for analyst approval

Examples

What an agentic SOC actually does

Three alert types, three agent trails. Real median timings from SocSage production.

Example 01 · 62s median

Impossible travel (BEC precursor)

Agents correlate the suspicious login against inbox-rule changes, MFA method additions, and mail-forwarding rules. If three of those are present, the swarm recommends session revoke and waits at the HITL gate.

Example 02 · 48s median

Anonymous IP (VPN false-positive)

Agents check the user's historical VPN baseline, device posture, and time-of-day pattern. ~70% are auto-closed as benign with full audit trail. Nothing hits a human queue.

Example 03 · 74s median

Workspace mass-share

Agents read the Drive audit log, identify the share scope (external / public / domain), map to sensitivity labels, and escalate only if sensitivity + scope cross the risk threshold.

FAQ

Agentic SOC: frequently asked questions

What is an agentic SOC?

An agentic SOC is a Security Operations Centre where AI agents triage, investigate and enrich security alerts autonomously. A human analyst approves every destructive action (session revoke, MFA reset, tenant quarantine). The agents reason step-by-step about the evidence in front of them — they are not running fixed playbooks.

How is an agentic SOC different from SOAR?

SOAR automates a fixed sequence of steps written as a playbook. An agentic SOC lets specialist AI agents choose which enrichment to run, which tool to call, and when to stop — based on what the investigation is actually showing. SOAR breaks on the edge case; agentic SOCs reason through it.

How is an agentic SOC different from MDR?

MDR is a human-led outsourced service: you send alerts to a third-party SOC, their analysts investigate, they escalate what matters. An agentic SOC is software: the AI does the triage and enrichment on your own tenant, and your own analyst approves the final action. The MSP keeps ownership of the client relationship.

Is an agentic SOC safe to let loose on a production tenant?

Only with human-in-the-loop on destructive actions. A well-designed agentic SOC lets the agents do unlimited read-only enrichment, but holds any irreversible change (session revoke, account disable, device isolation, mailbox quarantine) at a human approval gate. That's how SocSage is deployed on every tenant.

What's a realistic triage time in an agentic SOC?

SocSage's median time from raw alert to fully-investigated ticket is 62 seconds across Microsoft Sentinel and Google Workspace alerts. Human approval on destructive actions adds whatever the analyst takes to respond — typically 2–5 minutes in business hours.

Do I still need human analysts?

Yes. The agents handle the volume; the humans own the judgement. Most teams that deploy an agentic SOC keep 1–2 analysts per 25–50 tenants — where they used to need 4–6 to handle the same alert load.
