Executive Summary
Endpoint Detection and Response is now essential for UK SMEs. Traditional antivirus can no longer keep pace with the speed and sophistication of modern threats. EDR provides the visibility, detection capability, and response actions needed to protect businesses in 2026.
SMEs typically prioritise three things when selecting security tools. They need solid protection against ransomware and advanced attacks, clarity over who is responsible for monitoring and responding, and an operational model that does not overwhelm their internal IT teams. This guide explains EDR in plain English, offers a practical 15 question scorecard, and highlights why real security outcomes depend on both the technology and the partner who runs it.
The scorecard has been designed for SME leaders and IT managers to compare EDR platforms and managed service providers fairly. Get Support uses similar criteria internally and focuses on delivering a managed approach where alert handling, investigation, response, and continual improvement are owned by us rather than by the customer.
Introduction
The EDR market has grown rapidly, and it has become harder than ever for SMEs to understand what they are really buying. Vendor websites often focus on artificial intelligence, dashboards, and long feature lists that look impressive but do not guarantee a security outcome. There is a significant difference between buying a security product and buying a security result.
EDR tools generate alerts and provide the data needed to investigate threats. They do not replace the need for someone to interpret, investigate, and take action. For SMEs without dedicated security staff, the challenge usually lies not in buying the tool but in owning the day to day responsibilities that follow.
This guide simplifies the decision making process. It explains EDR in accessible terms, presents a practical scorecard for evaluation, and outlines how Get Support delivers a managed EDR service designed for UK SMEs who want outcomes rather than dashboards.
EDR in Plain English
What it is
EDR stands for Endpoint Detection and Response. It continuously monitors endpoints, such as laptops and servers, for suspicious activity. It detects threats in real time, provides in depth visibility, and allows security teams or managed partners to investigate and respond quickly.
How it differs from antivirus
Antivirus tools are mainly designed to stop known malware. They work using signatures and pattern matching. Modern threats often do not look like traditional malware. They might use scripting tools, legitimate software, or unusual behaviour to remain hidden. EDR looks for activity that is out of the ordinary, even if the attack does not contain a known malicious file. This behavioural approach is essential in 2026.
Where MDR fits and why many SMEs need it
Managed Detection and Response, or MDR, adds a dedicated security team on top of the EDR technology. This team monitors alerts, investigates suspicious activity, and takes action. Most SMEs do not have their own security analysts, which is why MDR has become the practical choice for businesses that want reliable protection without building an internal security operations centre.

Common Buying Mistakes (and How Get Support Avoids Them)
Choosing based on features alone
A long feature list does not guarantee real protection. Get Support focuses on the capabilities that deliver outcomes, not just the features that look impressive.
Underestimating the importance of configuration
EDR systems need careful setup and tuning. Poorly configured tools can create noise or miss threats. We manage baselining, tuning, and policy updates.
Skipping a pilot
A pilot demonstrates how the tool behaves in your environment. Get Support guides SMEs through a structured pilot to validate the platform and the operating model.
No incident plan or escalation path
When an incident occurs, delayed action increases impact. We provide a clear escalation plan with documented responsibilities and expected actions.
Lack of reporting and improvement cycles
Security needs to evolve over time. We deliver monthly reporting and quarterly reviews to ensure continual improvement and visibility.

FAQs
Yes. Modern attacks target SMEs as often as large companies. Criminals use automated tools that scan for vulnerabilities across businesses of all sizes. EDR provides the behavioural detection and response capability needed to stop threats that antivirus alone cannot handle. For most SMEs, EDR is now considered essential security.
Antivirus protects against known threats by matching files to known signatures. EDR analyses behaviour and can detect suspicious or malicious activity even when the threat is new or fileless. Antivirus remains useful, but EDR is the layer that detects and responds to the advanced attacks that dominate today’s threat landscape.
EDR is the technology. MDR is the managed service built on top of that technology. If your organisation has a 24 hour internal security team, EDR alone may be enough. Most SMEs do not, which is why MDR is the more reliable route. MDR ensures that experts are monitoring alerts, investigating activity, and taking action on your behalf.
A structured approach is the best way to compare options. Use a scorecard that covers detection capability, response actions, tuning, reporting, pricing, and operational ownership. The most important element is understanding who handles alerts, who investigates, and who is responsible for responding. Tools alone do not create security.
Managed EDR includes deployment, configuration, monitoring, alert handling, investigation, containment, reporting, and continuous improvement. When combined with a SOC, it also provides around the clock oversight and response. This allows SMEs to gain the benefits of advanced endpoint protection without building their own security team.
