What is SIEM in simple terms?

SIEM stands for Security Information and Event Management. It collects log data from across your entire network — firewalls, servers, endpoints, cloud apps — and analyses it in real time to detect suspicious activity. Think of it as a security camera system for your digital infrastructure, with an analyst watching the feeds 24/7.

Why should I outsource my SIEM?

Running SIEM in-house requires specialist security analysts earning £55K–£85K each, expensive tooling licences, and round-the-clock staffing. Most businesses find it 3–5x cheaper to outsource SIEM to a managed provider who already has the tools, expertise, and 24/7 SOC team in place.

What is a SOC and do I need one?

A Security Operations Centre (SOC) is a team of security analysts who monitor your systems around the clock, investigate alerts, and respond to threats. If your business handles sensitive data, processes payments, or must meet compliance requirements (GDPR, ISO 27001, Cyber Essentials), you need SOC-level monitoring — either in-house or outsourced.

How does SIEM differ from antivirus?

Antivirus protects individual devices by scanning for known malware signatures. SIEM monitors your entire network at a higher level — correlating events across firewalls, servers, email, endpoints, and cloud services to detect sophisticated attacks that antivirus alone would miss, such as lateral movement, privilege escalation, and insider threats.

What compliance requirements does SIEM help with?

SIEM is essential for meeting compliance frameworks including ISO 27001, Cyber Essentials Plus, PCI DSS, GDPR, and NHS DSPT. It provides continuous monitoring, audit-ready log retention, incident detection, and automated compliance reporting — all requirements that auditors specifically look for.

How long does it take to set up managed SIEM?

A managed SIEM service can typically be deployed within 2–4 weeks. This includes log source integration, baseline configuration, alert tuning, and SOC onboarding. Most providers handle the entire setup, so there is minimal disruption to your business operations.
