MDR
Managed Detection and Response Services
Arc’s managed detection and response (MDR) service monitors, detects and responds to cyber threats in real time. 24/7 UK-based support with expert threat response.


Cyber threats aren’t just more frequent, they’re more sophisticated, faster-moving, and increasingly difficult for traditional tools to stop. That’s why businesses need more than just firewalls and antivirus software. They need visibility, intelligence, and real-time defence.
Arc’s Managed Detection and Response (MDR) provides 24/7 monitoring, rapid threat detection, and expert-led response. We combine leading threat detection technology with human analysis to spot and stop malicious activity before it causes damage.
MDR works best when integrated with a broader cybersecurity approach. At Arc, we help you build a layered defence that includes:
• Endpoint Security for device protection
• Email Security to stop phishing and malware
• Penetration Software Testing to identify system vulnerabilities
• User Awareness Training & Policy Development
Our goal is to deliver protection, visibility, and control without overcomplicating your day-to-day operations.

What Is Managed Detection and Response?
MDR is a fully managed cybersecurity service that continuously monitors your IT environment, detects suspicious behaviour, and responds to confirmed threats. It goes beyond passive monitoring, offering active investigation and response from a team of specialists.
Our MDR offering includes:
- 24/7 threat monitoring and alerting
- Behavioural analytics to detect stealthy attacks
- Rapid incident triage and escalation
- Root cause analysis and remediation support
- Full integration with existing security tools
It’s ideal for organisations that need round-the-clock protection but don’t have the in-house resources to build and run a full Security Operations Centre (SOC).
