What is MDR and how is it different from antivirus?

Managed Detection and Response (MDR) combines advanced endpoint detection technology (EDR) with a 24/7 team of security analysts who actively hunt for threats, investigate alerts, and respond to incidents in real time. Unlike antivirus, which only blocks known malware signatures, MDR detects sophisticated attacks including fileless malware, living-off-the-land techniques, and zero-day exploits.

Does MDR protect against ransomware?

Yes — ransomware protection is one of the primary benefits of MDR. The service monitors every endpoint for ransomware indicators, including unusual file encryption activity, privilege escalation, and lateral movement. When detected, the MDR team can automatically isolate the affected device within seconds, preventing the attack from spreading across your network.

What is EDR and do I need it?

Endpoint Detection and Response (EDR) is the software agent installed on each device that continuously monitors for suspicious behaviour. EDR alone generates alerts — but without a team to investigate and respond to those alerts 24/7, threats can go unaddressed. MDR adds that human expertise on top of EDR, making it a complete solution.

How much does MDR cost for a small business?

MDR typically costs between £8 and £25 per endpoint per month, depending on the service level. For a 20-person business, that is roughly £160–£500 per month — significantly less than the average ransomware recovery cost of £1.2 million. Most providers offer tiered packages to match different risk profiles and budgets.

Can MDR work alongside our existing IT support?

Absolutely. MDR is a specialist security layer that complements your existing IT support, whether in-house or outsourced. Your IT team handles day-to-day operations while the MDR provider focuses exclusively on threat detection and response. Many businesses run both managed IT support and MDR from the same provider for seamless coordination.

How quickly does MDR respond to a threat?

A good MDR provider detects and begins responding to threats within minutes. Automated containment actions — such as isolating an infected endpoint — can execute in under 60 seconds. Human analyst investigation and full incident response typically begins within 15 minutes of detection.
