Managed SOC Services — 24/7 Monitoring, MDR & Incident Response
A Security Operations Centre (SOC) watches your systems around the clock, separates real attacks from noise, and acts before an intrusion becomes a breach. Most organisations cannot staff a 24/7 team of analysts, threat hunters and incident responders — a managed SOC gives you that capability as a service.
Mutex Systems delivers SOC and MDR as fully managed, co-managed or build-and-transfer services on Microsoft Sentinel, Splunk or IBM QRadar, with Microsoft Defender XDR integration, proactive threat hunting and incident response that starts within one hour.

Why it matters now
Based on incidents and figures in our UK & Europe threat report.
- Attackers increasingly steal data quietly rather than encrypt it — without monitoring, many breaches are only discovered from a leak-site post.
- NIS2, DORA, UK GDPR and PTA CTDISR all impose short incident-reporting deadlines that are impossible to meet without continuous detection.
- OT and building systems were attacked across Europe this autumn; most organisations have no visibility of them at all.
What we deliver
24/7 Monitoring & Alert Triage
Continuous monitoring of endpoints, identity, cloud, email and network, with analysts triaging every alert and escalating only what matters.
Managed Detection & Response (MDR)
Proactive threat hunting plus authorised containment — isolating hosts, disabling accounts and blocking indicators with documented evidence.
SIEM Onboarding & Management
Microsoft Sentinel, Splunk or QRadar deployment, log-source onboarding, tuning and cost control.
Detection Engineering
Use cases mapped to MITRE ATT&CK and to your threat model, tested and improved continuously.
Learn moreIncident Response & Forensics
Senior responders on retainer, a 24-hour hotline, chain-of-custody forensics and regulator notification support.
Cloud & Identity Threat Detection
Azure AD/Entra, Microsoft 365, AWS and GCP control-plane monitoring for account takeover and privilege abuse.
OT & IoT Security Monitoring
Passive monitoring of industrial and building networks for new connections, logins and set-point changes — the gap exposed by the 2026 controller attacks.
Vulnerability & Exposure Management
Continuous scanning and external attack-surface monitoring feeding the SOC, so new exposure is caught in days.
Compliance Reporting
Monthly reports and incident timelines that support ISO 27001, SOC 2, NIS2, DORA, UK GDPR, SBP and CTDISR obligations.

Frequently asked questions
What is a managed SOC?
A managed Security Operations Centre is a team of security analysts, threat hunters and incident responders who monitor your systems 24/7 on your behalf, using a SIEM and detection tooling, and respond to threats as they happen.
What is the difference between a SOC and MDR?
A SOC focuses on monitoring, triage and escalation. Managed detection and response (MDR) adds proactive threat hunting and the authority to take containment actions — such as isolating a device or disabling an account — on your behalf.
Which SIEM platforms do you support?
Microsoft Sentinel, Splunk and IBM QRadar, with Microsoft Defender XDR integration. We can work with your existing SIEM or deploy one as part of the service.
Can you monitor OT and building systems?
Yes. We add passive monitoring of industrial and building networks so that new connections, logins and configuration changes on controllers are detected — the gap behind the 2026 refrigeration-controller attacks in Europe.
How quickly do you respond to an incident?
For active incidents our responders begin initial response within one hour, with a 24-hour hotline. Authorised containment actions are agreed in advance so the SOC can act immediately.
Does a managed SOC help with NIS2 and DORA reporting?
Yes. Continuous detection and documented incident timelines are what make the 24-hour and 72-hour notification deadlines under NIS2, DORA and UK GDPR achievable, and grComply tracks those deadlines.
Do you offer co-managed SOC?
Yes. You can keep your own analysts in the loop while we provide 24/7 coverage, detection engineering and incident response, or we can build a SOC for you and transfer it to your team.
