Security Automation in 2025: A Comprehensive Guide

Updated August 25, 2025

What is Security Automation?

Security automation uses scripts and SOAR tools to perform routine detection and response steps so analysts spend time on judgment, not grunt work. This includes gathering context, blocking IPs, and opening tickets. Done right, it shrinks dwell time and burnout simultaneously.

Core Categories of Security Automation Solutions

User and Entity Behavior Analytics

User and Entity Behavior Analytics establishes baselines of normal activity for users, accounts, and devices. It then flags anomalies that may indicate compromised credentials, insider abuse, or malware.

Splunk Cloud SIEM

Exabeam

Palo Alto Cortex XSIAM

Security Information and Event Management

Security Information and Event Management systems aggregate and analyze logs from across IT environments. They detect incidents, centralize alerts, and generate compliance reports to support investigations.

Security Orchestration, Automation, and Response

Security Orchestration, Automation, and Response platforms streamline incident response. By automating repetitive tasks and integrating tools, they enable faster and more consistent threat mitigation.

## Category Overview ### Introduction Security Automation transforms security operations from reactive firefighting into proactive, orchestrated response. Playbooks, machine learning, and standardized data models allow teams to scale incident handling without scaling headcount. In 2025, SOAR is evolving into AI-driven assistants that integrate with SIEM and XDR, while open standards like OCSF and OpenTelemetry reduce vendor lock-in. ## Quarterly Trends & News | Theme | Update | |---|---| | **Open standards adoption** | OCSF and OpenTelemetry simplify data ingestion and interoperability. | | **SOAR redefined** | Traditional SOAR platforms are being absorbed into SIEM/XDR as AI copilots enhance automation. | | **AI copilots for analysts** | Assistants triage, enrich, and recommend response actions, cutting MTTR. | | **Defensive knowledge graphs** | Frameworks like MITRE D3FEND formalize defensive countermeasures for automation. | | **Cost-driven automation** | Teams automate repetitive tasks (enrichment, case management) to combat alert fatigue. | ## Common Terms & Definitions | Term | Definition | |---|---| | **SOAR** | Security Orchestration, Automation, and Response—automated workflows for incidents. | | **OCSF** | Open Cybersecurity Schema Framework for normalized security data. | | **OpenTelemetry (OTel)** | Standard for collecting logs, traces, and metrics across systems. | | **Playbook** | Predefined sequence of automated response actions. | | **D3FEND** | MITRE’s ontology of defensive techniques to guide control mapping. |

Key Considerations
