SOAR: incident response automation
Detecting a threat in time doesn't help much if the response depends on an analyst being available to act manually. SOAR solves exactly that problem. Here we explain what it is, how it connects with the SIEM, and which platforms Tenacron uses to implement it.
What is a SOAR?
SOAR (Security Orchestration, Automation and Response) is a platform that connects an organization's different security tools -SIEM, firewalls, EDR, email, identity- and executes automated playbooks in response to a triggered alert, without relying on an analyst to manually intervene at every step.
SIEM detects, SOAR responds
It's a common mistake to treat SIEM and SOAR as the same thing. They're not, and understanding the difference matters when scoping a project:
| SIEM | SOAR | |
|---|---|---|
| Main function | Centralize and correlate events to detect | Orchestrate and automate the response to what was detected |
| Typical output | Alert | Action (block, isolate, notify, ticket) |
| Reduces | MTTD (detection time) | MTTR (response/containment time) |
A typical SOAR playbook, when facing a confirmed malware alert on an endpoint, can: isolate the machine from the network, revoke the user's active sessions, open a ticket with all the evidence attached, and notify the on-call team -all within seconds, not the time it takes an analyst to review the console.
When does it make sense to add a SOAR?
- When the SIEM's alert volume already exceeds the L1/L2 team's manual response capacity.
- When there are repetitive response actions (isolating a host, blocking a hash, revoking credentials) that are executed manually every time.
- When reducing MTTR is needed to meet operational continuity goals or contractual/regulatory requirements.
- When you need standardized evidence and traceability for every incident, instead of relying on each analyst documenting things differently.
Playbooks: the heart of SOAR
A playbook is a predefined sequence of steps for a given type of incident. Some examples we implement frequently:
- Phishing reported by a user: automatic analysis of the email and attachments, blocking the sender, and searching for other recipients who received it.
- Malware detected on an endpoint: network isolation of the machine, basic forensic evidence capture, ticket creation.
- Anomalous account activity: revoking active sessions, forcing a password change, notifying the user and the security team.
These playbooks are designed based on real scenarios we've faced restoring operations for organizations of more than 600 users after ransomware and DDoS incidents -they're not generic templates, but responses tailored to what actually happens during an incident.
Frequently asked questions
Can you have a SOAR without a SIEM?
It's possible to automate specific flows without a formal SIEM, but SOAR's greatest value appears when it's connected to a SIEM (or NG-SIEM) that provides correlated alerts with enough context to decide on an automated response.
Is it risky to automate incident response?
The risk is managed through design: the highest-impact playbooks (for example, isolating a production server) usually include a human approval step, while low-risk, high-frequency actions are fully automated.
What if we already use automation tools like n8n for other parts of the business?
That same platform can be leveraged to orchestrate security playbooks instead of adding another dedicated SOAR tool -it's one of the combinations we evaluate case by case.
