Threat Detection

Find threats before they find you.

24/7 MDR, XDR, and cloud security monitoring from our Norwich SOC. Human analysts, not just automation.

Managed Detection & Response

Managed Detection & Response

Our Managed Detection and Response service delivers 24/7 threat monitoring, detection, and response from our Norwich-based Security Operations Centre. Unlike automated tools alone, MDR combines technology with human expertise -- our analysts investigate alerts, hunt for threats, and respond when it matters.

Coverage spans endpoints, network traffic, cloud environments, and email -- giving you a complete picture of your threat landscape with real humans acting on what they find.

02 -- Extended Detection & Response (XDR)

Extended Detection & Response (XDR)

Extended Detection and Response (XDR) unifies telemetry from across your environment -- endpoints, identity, email, cloud, and network -- into a single correlated view. This breaks down silos and dramatically reduces the time to detect and respond to threats.

We deploy and manage XDR platforms on your behalf, tuning detection rules, managing integrations, and ensuring your security stack delivers maximum value without generating noise.

Unified multi-domain telemetry
Cross-source threat correlation
Automated investigation and triage
Identity threat detection
SIEM integration available

Cloud Security Monitoring
03 -- Cloud Security Monitoring

Cloud Security Monitoring

Cloud environments -- Microsoft Azure, Microsoft 365, and beyond -- introduce new attack surfaces that traditional monitoring tools miss. Misconfigured storage, overprivileged identities, and anomalous admin behaviour can all go undetected without specialised cloud monitoring.

We deploy cloud-native security tooling and monitor your cloud tenants continuously, alerting on anomalies, misconfigurations, and suspicious activity in real time.

04 -- Email Threat Detection

Email Threat Detection

Email remains the number one vector for cyber attacks. Phishing, business email compromise, malware delivery, and impersonation attacks are increasingly sophisticated -- and traditional spam filters are no longer enough.

We deploy advanced email threat detection platforms that use AI and behavioural analysis to identify and block threats that bypass standard filters, with real-time protection and user-level reporting.

Business email compromise protection
Impersonation and spoofing detection
Link and attachment sandboxing
Retroactive threat remediation

Network Threat Monitoring
05 -- Network Threat Monitoring

Network Threat Monitoring

Attackers who get past your perimeter need to move laterally to reach their targets. Network threat monitoring detects anomalous behaviour within your infrastructure -- unusual connections, lateral movement, and data exfiltration attempts -- before they escalate.

Using network detection and response (NDR) technology alongside our SOC analysts, we monitor your internal network traffic and alert on suspicious patterns in real time.

06 -- Insider Threat Monitoring

Insider Threat Monitoring

Not all threats come from outside. Malicious insiders, compromised accounts, and well-meaning employees making poor decisions all pose significant risks. Insider threat monitoring helps you detect unusual behaviour before it becomes a serious incident.

We deploy user and entity behaviour analytics (UEBA) tools that establish baselines for normal behaviour and alert on deviations -- protecting your data without creating a surveillance culture.
