What is MDR and how can it help my business?

Managed Detection and Response (MDR) is a cybersecurity service that provides 24/7 monitoring, threat detection, and response capabilities using automated and human methods. MDR helps organisations stay ahead of new threats, reduce the risk of breaches, improve security, and free up internal resources. Implementing MDR can be more cost-effective than setting up an internal security operations centre.

“MDR is the element many companies are still missing today. Undoubtedly investment in security products and solutions will have been made, however it is the investment in the team that manage and administer these solutions that often lacks, either in terms of resource numbers or skill set of those resources. Analysing and responding accordingly to hundreds of thousands of alerts per day is a challenge most businesses can’t meet.

Outsourcing this pressure to a world leading team of security specialists with specifically designed threat hunting systems is the only real way to know your systems and the security platforms you have wrapped around them are delivering, and when they don’t, that someone will catch that threat in real time.”

Russell Henderson, Technical Director at Trustack

“The technology is there to support us from zero-day onwards in terms of looking at threats and there’s the whole peace of mind that we’ve got knowing we have eyes on our system 24×7.”


Maeve Collier, Director of ICT and Change at Beyond Housing

What is the difference between EDR and MDR?

EDR is a software solution that collects and stores telemetry data from endpoints, such as computers, laptops, and mobile devices. This data includes file system changes, process creation, and network activity.

EDR solutions then use this data to detect threats and send alerts to the relevant team.

MDR provides EDR capabilities but also contains additional services such as threat hunting, incident response, and remediation. Providers of MDR usually have a security team who monitor the threats and respond to any incidents.

MDR offers a wide range of security services with experts monitoring endpoints around the clock. This helps them respond faster and more effectively to security incidents compared to individual IT teams.

What does MDR do?

MDR is a security service that uses technology and human expertise to find and respond to threats. It includes services like Endpoint Detection and Response, threat hunting, and incident response. 

By actively seeking out threats and responding to security incidents, organisations can better protect their systems and data. 

Using an MDR solution can help improve security, save money, and make more resources available.

Does MDR replace SIEM?

No, Managed Detection and Response (MDR) does not replace Security Information and Event Management (SIEM). Both are valuable tools but offer different capabilities.

A SIEM solution gathers and analyses security logs from different sources like firewalls, intrusion detection systems, and web application firewalls. You can use these logs to detect threats, investigate incidents, and comply with security regulations.
MDR is a security service that uses a combination of technology and human expertise to detect and respond to threats. 

Most providers usually have a security team who monitor and respond to threats on a 24/7 basis.

Organisations should use both MDR and SIEM for better security and to improve overall security posture.
