MDR
Managed Detection and Response services
Our managed detection and response service is designed to monitor, detect, and respond to cyber threats in real time. 24/7 UK-based support with expert threat response.
Cyber threats aren’t just more frequent, but they are increasingly sophisticated, fast-moving, and tougher for traditional tools to stop. That means it requires more than just firewalls and antivirus software to adequately deal with them. What businesses need is visibility, intelligence, and real-time defence.
Our MDR offers 24/7 monitoring, rapid threat detection, and expert-led response. We combine leading threat detection technology with human analysis to identify and stop malicious activity before it causes damage.
MDR works best when integrated with a broader cybersecurity approach. We help you build a layered defence that includes:
- Endpoint security for device protection
- E-mail security to prevent phishing and malware
- Penetration testing using software to locate system vulnerabilities
- User awareness training and policy development
We want to provide you with protection, visibility, and control without overcomplicating your everyday operations.
MDR is a fully managed cyber security service that can continuously monitor your IT environment for suspicious behaviour and respond to threats that have been confirmed. It goes beyond passive monitoring; active investigation and response are provided by a team of specialists.
Our MDR offering includes:
- 24/7 Threat Monitoring and Alerting
- Behavioural analytics for detection of stealthy attacks
- Rapid triaging of incidents and escalation
- Root cause analysis and remediation support
- Full integration with existing security tools
It is ideal for organisations requiring protection on a 24×7 basis but without the in-house resourcing to build and operate a full Security Operations Centre – SOC.
Key benefits
Rapid threat detection
Detect and contain attacks before they can spread laterally across the network.
24/7 security coverage
Cyber threats don’t work 9–5, so neither do we. Our UK-based team monitors your systems at all times.
Expert response
Our analysts go beyond mere alert flagging to investigate and provide clear, actionable guidance.
Reduced dwell time
The faster an attacker is identified, the less damage they can do. MDR drastically shortens the response window.
Stronger compliance and audit readiness
Supports your efforts to meet GDPR, Cyber Essentials, and other regulatory requirements.
