Human-in-the-loop security automation uses connected tools and repeatable workflows to handle routine security investigation and response, while pausing for analyst review before consequential actions. The key design decision is where automation can act on its own and where a person needs to assess the evidence and approve what happens next.
What human-in-the-loop security automation means
Security automation links tools and runs predefined steps in response to alerts or other events. In a human-in-the-loop workflow, an analyst is part of the process: the workflow may gather evidence and recommend a response automatically, but it waits for a person to authorize a sensitive step.
SOAR—security orchestration, automation and response—is the closest established operational category. SOAR playbooks connect security products and automate repeatable incident-response work, while escalating cases that need judgment. Microsoft describes playbooks as a way to enrich alerts, coordinate actions across tools and guide consistent investigation without removing human oversight: Microsoft Security’s SOAR overview.
This is not simply a choice between “automated” and “manual.” A workflow can automate the predictable parts of an investigation and leave a person in control of actions that could disrupt users, systems or business operations.

How a human-in-the-loop workflow works
A playbook can begin when a security alert arrives, collect context from connected systems, and then either continue automatically or stop at a defined approval point. For a possible account compromise, Microsoft describes gathering identity-management data, checking the sign-in against threat intelligence, inspecting endpoint activity for compromise or lateral movement, reviewing sign-in history and coordinating containment.
- Trigger: An alert or other event starts the playbook.
- Enrich: The workflow gathers relevant identity, endpoint, threat-intelligence or sign-in information.
- Assess: Conditional logic correlates the evidence and determines which path to follow.
- Document and notify: It can record the case, create a ticket or alert stakeholders.
- Approve or act: Routine steps may proceed automatically; a sensitive action can pause until an authorized analyst reviews the evidence.
Examples of possible response actions include blocking a malicious IP address or disabling a compromised account. A platform’s ability to perform an action does not mean an organization should let it run without approval. The organization sets that boundary in the workflow.
What to automate and what to hold for approval
A practical starting policy is to automate steps that are repeatable, well understood and reversible, and require human review when a decision is sensitive, ambiguous or likely to disrupt business operations. This is a design approach, not a universal threshold prescribed by one standard.
- Often suitable for automation: routine alert enrichment, gathering known context, documenting findings and notifying the appropriate team when the data and conditions are well understood.
- Often worth a human checkpoint: actions with significant operational impact, uncertain evidence, or consequences that are difficult to reverse.
- Useful as a manual task: an unusual, nuanced or infrequent step that cannot be expressed reliably as a repeatable rule.
Palo Alto Networks Academy describes playbooks that can include conditional paths, manual tasks and approval tasks. Its guide explains that a manual task can guide an analyst when an action is too unique, nuanced or infrequent to automate, while an approval task can wait for a SOC analyst to verify that a sensitive action is needed and relevant: Palo Alto Networks Academy’s SOAR guide.
Where oversight belongs in the workflow
An approval control is useful only if it defines how a decision is made. The workflow should make clear which steps run automatically, which stop for approval, who may approve them, what evidence the reviewer sees and what happens if approval does not arrive. It should also record the recommendation, relevant evidence, approval and execution result.
“Human in the loop” usually means a person must take part in or authorize a step before it proceeds. “Human on the loop” generally describes a person monitoring automation that can act without a per-action approval. The terms are useful distinctions, but the important practical question is whether the workflow actually blocks execution until the required person approves it.

Vendor materials describe different ways to implement oversight. CrowdStrike says administrators can set autonomy per workflow, from human approval to fully autonomous execution, and that agent actions and workflow runs are logged and auditable. Elastic says its AI agents can gather context and present findings for analyst approval before an action executes. These are product descriptions, not independent evaluations: CrowdStrike Charlotte Agentic SOAR and Elastic AI agents.
Human review does not automatically make a workflow safe. An approval gate can fail to provide meaningful oversight if the reviewer lacks relevant context, authority, time or a reliable way to stop the action. The sources describe workflow mechanisms and recommendations, but do not establish a single ideal approval threshold.
Security automation and AI-related identities
Automation also depends on identities and credentials of its own. An AWS-authored presentation hosted by NIST identifies service accounts, API keys, OAuth tokens, agent-to-agent trust, pipeline credentials and orchestration secrets as non-human identities that may be missing from incident-response inventories.
The presentation recommends mapping these identities to business functions, documenting their potential blast radius, creating and testing revocation playbooks, assigning a human owner and running tabletop simulations. This connects workflow oversight to incident readiness: responders need to know which machine identities an automated system uses and how to revoke them without creating avoidable business impact. See the AWS-authored presentation hosted by NIST.

Product fit depends on the tools an organization already uses and the controls it needs—not just on the number of advertised integrations. Examples in vendor materials include Palo Alto Networks Cortex XSOAR, CrowdStrike Charlotte Agentic SOAR and Elastic Workflows; their inclusion here is illustrative, not an endorsement.
| What to compare | Questions to ask |
|---|---|
| Where the automation runs | Is it native to the organization’s SIEM, as Elastic presents Workflows, or a separate SOAR platform designed to connect across a security stack, as Cortex XSOAR presents itself? |
| Integration fit | Does it work with the actual SIEM, endpoint detection and response, identity, email, ticketing and threat-intelligence tools in use? |
| Workflow controls | Can teams create conditional paths, manual tasks and approval gates? Can they test and debug workflows before relying on them? |
| Oversight and records | Can analysts see the evidence behind a recommendation? Are actions, workflow runs and approvals recorded in a way the organization can audit? |
| Operational evidence | Are claimed results customer-reported, aggregated by a vendor or independently assessed—and are they comparable with the organization’s own baseline? |

How to interpret performance claims
Vendor-reported figures are not neutral benchmarks. Palo Alto Networks’ undated product page claims a 90% reduction in time spent on incidents, based on aggregated customer use cases that include its own SOC. Its undated North Dakota IT customer example says 196 playbooks helped close more than 60% of incidents and describes operational efficiencies equivalent to adding eight to 10 SOC analysts. Those are vendor claims about specific customer use cases, not general expected results or independent estimates of labor impact.
The sources cited here do not establish a broadly applicable, neutral statistic for the effectiveness of human-in-the-loop security automation. To assess a claim for your organization, ask what was measured, under what conditions, against which baseline and by whom.
