A Security Operations Centre monitors your environment continuously for threats — detecting attacks in progress before they become incidents. Large enterprises have internal SOCs with teams of analysts. Small businesses can access the same capability through managed SOC services.
The mean time to detect a cyber intrusion in a business environment is 207 days, according to IBM's Cost of a Data Breach Report. That's over six months from initial compromise to detection — six months during which an attacker has persistent access to your environment, is moving laterally, exfiltrating data, and positioning for a high-impact final action (ransomware deployment, financial fraud, data sale).
The reason detection takes so long in most organisations is that there's nobody actively looking. Security events are logged. The logs are stored. But unless someone is reviewing those logs and correlating events across systems, the attacker's activity is invisible against the background noise of normal IT operations.
What a SOC Does
A Security Operations Centre combines technology (SIEM — Security Information and Event Management) with human analysts who review alerts, investigate anomalies, and respond to confirmed threats. The SIEM collects logs from endpoints, identity systems, email, network devices, and cloud services — correlating events across sources to identify attack patterns that individual log sources wouldn't reveal in isolation.
An example: a user logs in from Auckland at 9am (normal). At 11pm, the same account logs in from a European IP address (anomalous). At 11:05pm, that account accesses the HR document library (anomalous — this user normally only accesses project files). At 11:08pm, it downloads 2GB of files (very anomalous). Individually, each of these events might not trigger an alert. A SIEM correlating all four detects the pattern and alerts an analyst. A human analyst confirms the compromise and initiates incident response — within minutes of the exfiltration beginning, not six months later.
Managed SOC for SMBs
Building an internal SOC requires a team of security analysts (typically five or more to maintain 24/7 coverage), SIEM licensing and infrastructure, threat intelligence subscriptions, and significant ongoing investment in analyst training. This is out of reach for most small businesses. Managed SOC services provide the same capability on a shared model — the technology and analyst team are shared across multiple clients, reducing the per-client cost significantly.
Optimyze's SOC service provides 24/7 monitoring of client environments through Microsoft Sentinel — Microsoft's cloud-native SIEM. Client event data (endpoint telemetry from SentinelOne, identity logs from Entra ID, email security events, and network logs) flows into Sentinel and is monitored by security analysts. When a confirmed threat is identified, the client is contacted and response is initiated — at any hour, including weekends and public holidays.
What 24/7 Monitoring Changes
The practical impact of continuous monitoring: attacks that would previously run for months undetected are identified within hours. A ransomware precursor — lateral movement, privilege escalation, backup enumeration — typically precedes ransomware deployment by 24–72 hours. SOC monitoring catching these precursor activities stops ransomware before it deploys, rather than responding after encryption has already occurred.
The ROI of 24/7 monitoring is measured in incidents that didn't complete. Every attack caught in the lateral movement phase — before ransomware deploys or data is exfiltrated — represents a potential six-figure loss avoided.
