SOAR (Security Orchestration, Automation and Response)

Security orchestration, automation and response (SOAR) is a technology that automates and coordinates security operations tasks, connecting tools together and running predefined playbooks to handle repetitive investigation and response steps. SOAR reduces manual workload and speeds response by automating routine actions so analysts can focus on decisions that need human judgement.

Security orchestration, automation and response is a category of technology designed to make security operations faster and more consistent by automating repetitive work and connecting otherwise separate tools. Where a security information and event management platform detects and surfaces threats, SOAR focuses on what happens next: coordinating the investigation and response, often through automated playbooks that execute a defined sequence of steps.

The three parts of the name describe its functions. Orchestration connects disparate security tools so they can work together, for example letting a single workflow query a threat-intelligence source, check an endpoint tool and update a ticketing system. Automation executes routine tasks without human intervention, such as enriching an alert with context or blocking a known-malicious address. Response coordinates the actions taken to contain and remediate a threat, from notifying an analyst to isolating a device.

SOAR addresses two persistent problems in security operations: too many alerts and too few skilled staff. Analysts spend a large share of their time on repetitive steps, gathering context on an alert, checking indicators against intelligence sources, opening and updating tickets, that are necessary but do not require human judgement. Automating those steps through playbooks frees analysts to focus on investigation and decisions, and it makes response faster and more consistent because the machine does not tire or forget a step.

A playbook is the central concept. It is a defined, often visual, workflow that specifies how to handle a particular type of alert or incident: the checks to run, the enrichment to gather, the conditions under which to act automatically, and the points at which a human must approve a decision. Well-designed playbooks encode an organisation’s best response practice so that every analyst handles a given scenario the same proven way.

SOAR does not remove the need for human analysts; it amplifies them. Decisions with significant consequences, such as taking a production system offline, still require human authority, and playbooks must be built and maintained by people who understand both the tools and the threats. Poorly designed automation can act on false positives or take disruptive action inappropriately, so governance matters. Used well, SOAR measurably reduces mean time to respond.

Governance is essential to safe automation. A playbook that can take disruptive action, such as isolating a production system, must include the right approval gates and guard against acting on false positives, because automation executes a mistake as faithfully as a correct decision. Well-designed SOAR keeps humans in control of consequential actions while automating the repetitive enrichment and triage that consume analyst time, which is where it delivers most of its measurable benefit.

Within its managed SOC, Precursor uses orchestration and automation to handle routine triage and enrichment at machine speed, so its analysts spend their time on investigation and response decisions rather than repetitive steps.

Managed SOC

Security information and event management (SIEM) is a technology that aggregates log and event data from across an organisation’s systems, then normalises, correlates and analyses it to detect security threats and support investigation. A SIEM is the central nervous system of many security operations centres, turning scattered logs into actionable alerts and a searchable record.

SOC (Security Operations Centre)

A security operations centre (SOC) is the team, processes and technology responsible for continuously monitoring an organisation’s environment, detecting security threats, investigating them and coordinating response. A SOC can be built in-house, outsourced, or run as a hybrid, and typically operates 24/7 using a SIEM and other detection tooling.

MTTR and MTTD (Mean Time to Respond and Detect)

Mean time to detect (MTTD) is the average time taken to identify a security incident after it begins. Mean time to respond (MTTR) is the average time taken to contain or remediate it once detected. Together they are core metrics for measuring the effectiveness of a security operations centre or detection and response programme: lower is better.
