Managed Security Operations Centre (MSOC)

Enterprise-grade monitoring and response for ambitious businesses that can’t afford to take chances.

Strengthen Your Cyber Protection With Our Managed SOC Service

Juggling a number of different applications, systems, and setups makes it difficult to keep sight of potential cyber-attacks – and that’s before you factor in actually tackling them.

Evolving Threat Landscape

Sophisticated attacks now bypass conventional security tools, requiring advanced detection capabilities.

Resource Limitations

Building and staffing an in-house security operations team is prohibitively expensive for most organisations.

Compliance Requirements

Regulatory frameworks increasingly demand continuous monitoring and incident response capabilities.

Business Continuity Risks

Without rapid threat detection and containment, security incidents quickly escalate into operational disruptions.

Rapid Detection. Expert Response. No In-house Team Needed.

With the Nexus Managed SOC and SIEM solution, you can get on with running your business, safe in the knowledge that trained and experienced cyber security experts are looking out for dangers 24/7.

Offering a comprehensive detection and response solution, our MSOC service detects malicious and suspicious activity across three critical attack vectors: endpoint, network, and cloud. You’ll benefit from around-the-clock monitoring with real-time investigation and threat hunting, followed by threat isolation and remediation for complete peace of mind.

Plus, with our pay-per-user model, this solution scales with your business.

How Does a Managed Security Operations Centre Work?

Our managed SOC combines smart automation with human expertise to identify and stop bad actors targeting your endpoints and networks. Most threats are profiled and escalated automatically based on intelligence signals, with our team responding according to agreed SLAs and your preferred actions. This goes beyond basic virus detection—it includes protection against ransomware, DDoS attacks, and phishing attempts that could otherwise go unnoticed.

Continuous Threat Monitoring

Security experts actively hunt for threats across your entire environment, detecting suspicious activities that automated tools might miss.

Immediate Response Protocols

When threats are detected, our team takes appropriate action – from alerting to device isolation – without disrupting your operations.

Advanced Threat Intelligence

We identify sophisticated attack patterns beyond traditional viruses and ransomware, protecting against emerging threats.

Security Expertise with Local Insight

While our SOC operates internationally to ensure 24/7 protection, our South West team provides personalised support tailored to the needs of local businesses.

Threat Intelligence & Hunting

We monitor threat intelligence in real-time by connecting with premium intelligence-fed partners, providing you with the most extensive global collection of threat indicators. Our SOC analysts use intelligence telemetry to actively track down malicious individuals.

Breach Detection

Detect adversaries that evade traditional cyber defences such as firewalls and AV. Identifies attacker tactics, techniques and procedures (TTPs) and aligns with MITRE ATT&CK, producing a forensic timeline of chronological events to deter the intruder before a breach occurs.

Intrusion Monitoring

Real-time monitoring of malicious and suspicious activity, identifying indicators such as connections to terrorist nations, unauthorised TCP/UDP services, and backdoor connections to command-and-control servers.

Investigation and Remediation

We investigate all incidents that appear suspicious. We’ll also suggest and advise on remediation measures to contain the threat, with minimal disruption to your business operations.

SIEM-less log monitoring

Monitor, search, alert, and report on endpoint, network, and cloud threat vectors, including key log data from Windows and MacOS, firewalls, networked devices, Microsoft 365 and Azure AD – all without requiring a SIEM or SIEM hardware.
