Get in touch

Modern businesses face relentless threats to their IT security, from ransomware to targeted attacks exploiting human error or outdated systems. Our Managed Detection and Response (MDR) service provides the continuous visibility and advanced threat detection needed to stay protected and secure.

Our team monitor your environment around the clock, using behavioural analytics, threat intelligence, and machine learning to monitor, detect, and escalate real threat before they cause damage. With real-time insights and a team of experts watching over your endpoints, users, and M365 tenant, you can focus on business growth while we help protect your most critical assets.

What is Managed Detection & Response (MDR)?

Managed Detection & Response (MDR) is a proactive, intelligence-driven security service that continuously monitors your IT environment 24/7 to detect and escalate potential threats. By combining expert analysis with advanced tools, MDR helps strengthen your security posture by identifying hidden risks such as compromised user behaviour, lateral movement, and attempts to exploit known vulnerabilities.

Unlike traditional approaches that rely solely on signature-based detection or wait for alarms to trigger, MDR focuses on identifying patterns and anomalies that indicate malicious activity. Our team actively investigates signals across your devices and user behaviours, aiming to detect and contain threats early — often before they evolve into full-scale security incidents or disrupt your operations. Through advanced cyber security solutions, we work to ensure your systems remain protected and resilient.

Frequently Asked Questions

Is managed detection and response the same as EDR?

Managed Detection and Response (MDR) and Endpoint Detection and Response (EDR) are closely related but serve different roles in cyber security.

EDR focuses specifically on endpoint security, monitoring individual devices such as laptops, desktops, and mobile devices. It detects and responds to threats on these endpoints by analysing activity for signs of compromise, isolating infected devices, or blocking suspicious behavior.

In contrast, MDR is a broader service that oversees the entire IT environment, including endpoints, networks, and cloud systems. It combines EDR capabilities with proactive threat hunting, continuous monitoring, and real-time incident response across the organisation’s infrastructure. MDR offers a more comprehensive approach by leveraging multiple security tools to detect and mitigate threats before they spread or escalate.

What do managed detection and response services entail?

A Managed Detection and Response (MDR) service offers continuous monitoring, proactive threat detection, and rapid incident response to protect businesses from cyber threats. It includes 24/7 surveillance of IT environments using advanced security tools like SIEM and EDR, alongside expert threat hunting to identify hidden risks. In the event of a threat, MDR services provide immediate incident response to contain and mitigate damage. Additionally, they offer forensic analysis to understand the breach and improve overall security. MDR is ideal for businesses seeking comprehensive, expert-driven cyber security beyond traditional tools.

What is managed endpoint detection and response?

Endpoint Detection and Response (EDR) is a cyber security solution that continuously monitors endpoint devices for signs of malicious activity. It automatically detects potential threats and takes corrective actions, such as isolating infected devices or blocking harmful processes, to reduce the impact of security incidents. EDR enhances an organisation’s ability to respond quickly to emerging threats by providing real-time detection and automated remediation, helping protect critical systems and data from compromise.

Can I do my own network support in-house?

By swiftly responding to security incidents, businesses can effectively minimise potential damage and swiftly mitigate any risks or breaches. Managed detection and response (MDR) services play a crucial role in this process by providing organisations with the necessary response capabilities and incident investigation.

When an incident occurs, MDR services have the expertise and tools to quickly identify and assess the situation, allowing for a rapid and accurate response. This includes promptly containing and isolating the incident to prevent further spread and damage. With their comprehensive understanding of advanced threats and attack vectors, MDR services can swiftly analyse the incident to determine the scope and severity of the breach. This enables organisations to take immediate action, such as patching vulnerabilities or updating security measures, to mitigate any potential damage and prevent future incidents.

What is MDR in simple words?

Managed Detection and Response (MDR) is a comprehensive managed security solution that protects organisations from emerging threats by utilisng security experts, advanced tools, and threat identification. Key benefits include continuous 24/7 monitoring, proactive threat investigation, and the integration of our other security experitse for enhanced protection.
