Managed SOC & SOC as a service
explained
A managed SOC (Security Operations Centre) is a team of security analysts who monitor your IT environment 24/7, investigate threats, and respond to incidents on your behalf. Traditionally, a SOC required a dedicated in-house team — costing £150,000+ per year for even a minimal 3-person operation.
SOC as a service makes this capability available to London SMEs at a fraction of the cost. Coreitech's managed SOC integrates with your existing Microsoft 365 environment — using Defender for Business, Microsoft Sentinel, and Entra ID as the foundation, enriched with additional threat intelligence and a dedicated analyst team.
The result: your business has the same security monitoring capability as a FTSE 250 company's in-house security team — for a predictable monthly fee per user, with no recruitment, no tooling procurement, and no gaps during holidays or sick leave.
Why London SMEs need SOC monitoring in 2026: Sophisticated threats — ransomware, business email compromise, supply chain attacks — are no longer solely targeting enterprises. The majority of cyber attacks now target businesses with 10–250 staff. Without 24/7 monitoring, these attacks typically go undetected for an average of 197 days before discovery.
Why 24/7 monitoring matters
| Factor | With Managed SOC | Without SOC |
|---|---|---|
| Threat detection | Real-time, 24/7 | When someone notices (days–months) |
| Ransomware response | Containment in minutes | Full spread before discovery |
| Attack dwell time | Hours | Average 197 days undetected |
| Incident forensics | Full audit trail | Evidence often destroyed |
| Compliance reporting | Automated monthly | Manual, ad-hoc |
| Cost (20 users) | ~£600/month | £85K+ per incident |

Managed SOC & SOC as a service —
questions answered
Q.What is a managed SOC (Security Operations Centre)?
A managed SOC (Security Operations Centre) is an outsourced team of security analysts and engineers who monitor your IT environment 24/7 for threats, investigate suspicious activity, and respond to incidents on your behalf. Instead of building an in-house security team (which costs £150,000+ per year for even a minimal setup), businesses use SOC as a service to access enterprise-grade security monitoring for a fixed monthly fee.
Q.What is SOC as a service?
SOC as a service (SOCaaS) is a subscription-based model where an external security provider delivers Security Operations Centre capabilities — 24/7 monitoring, threat detection, incident response, SIEM, and vulnerability management — as a managed service. Coreitech provides SOC as a service for London businesses, integrating with Microsoft Defender, Sentinel, and other security tools your business already uses.
Q.What is the difference between a SOC and managed IT support?
Managed IT support covers the day-to-day operation of your IT — helpdesk, patch management, Microsoft 365 management, and infrastructure. Managed SOC is specifically focused on security — monitoring for threats, investigating alerts, and responding to incidents. Coreitech's Advanced managed IT plan includes core SOC monitoring; our standalone SOC service provides dedicated security operations with deeper SIEM capabilities and a dedicated security analyst.
Q.What does 24/7 security monitoring mean?
24/7 security monitoring means your IT environment — endpoints, servers, network, cloud services — is continuously monitored by automated detection tools and human analysts around the clock. When a threat indicator is detected, an alert is raised and investigated immediately — regardless of whether it's 3am on a Sunday. This is the critical difference between SOC monitoring and scheduled security scans.
Q.What is a managed security service provider (MSSP)?
A managed security service provider (MSSP) is a company that provides outsourced security monitoring and management. Unlike a general MSP (managed IT provider), an MSSP specialises in security services — SOC, threat detection, incident response, vulnerability management, and compliance. Coreitech operates as both an MSP and MSSP — providing fully managed IT support with integrated security operations.
Q.How quickly does the SOC respond to a security incident?
Coreitech's SOC targets a 15-minute initial response to confirmed security incidents. For critical incidents (active ransomware, confirmed breach), our protocol is immediate automated containment followed by human analyst triage within 15 minutes. For lower-severity alerts, response is within 1 hour during business hours and 4 hours out of hours (Standard SOC) or 24/7 (Advanced SOC).
Q.Does the SOC monitor Microsoft 365?
Yes. Microsoft 365 is one of the primary attack surfaces for UK businesses — phishing, account takeover, and data exfiltration all frequently target Microsoft 365 environments. Coreitech's SOC integrates with Microsoft Defender for Office 365, Entra ID, and Microsoft Sentinel to provide comprehensive monitoring of your Microsoft 365 tenant, including suspicious login activity, unusual email forwarding rules, and admin account access.
