Endpoint Detection and Response (EDR) Service for UK Businesses

EDR sits at the core of any modern managed cybersecurity programme because the endpoint is where most attacks land — a phished login, a malicious attachment, a stolen laptop. Traditional antivirus checks files against a list of known-bad signatures. EDR watches what software actually *does*, so it catches threats that have never been seen before. For UK SMEs, that gap matters: the Cyber Security Breaches Survey 2025 found 43% of UK businesses reported a breach or attack in the prior 12 months.

What does AMVIA's EDR service include?

Our EDR service deploys behavioural detection agents to every device, monitors them around the clock, and pairs the technology with human analysts who investigate and respond. You get the platform and the people in one accountable service — not a tool you are left to run yourself.

• Full endpoint coverage — EDR agents on all desktops, laptops and servers, providing continuous behavioural monitoring.
• Behavioural detection — Goes beyond signature-based detection to identify suspicious behaviour, fileless attacks and living-off-the-land techniques.
• Threat investigation — When a detection fires, our analysts reconstruct the full attack chain: what happened, how it got in, and what was affected.
• Automated response — Pre-configured actions isolate compromised endpoints, kill malicious processes and stop lateral movement before it spreads.
• Continuous updates — Detection rules and threat intelligence are updated continuously to track emerging threats.
• Visibility and reporting — Clear dashboards and regular reports on your endpoint security posture.

The detection engine is Microsoft Defender for Endpoint, the same enterprise platform built into Microsoft 365. If you already license it through Microsoft Defender for Business, AMVIA configures, tunes and monitors it so the capability you are paying for is actually switched on and watched.

How does endpoint detection and response work?

EDR works in five stages: it baselines normal behaviour on each device, flags deviations that match attacker techniques, alerts an analyst, contains the affected endpoint, and feeds the lesson back into detection rules. AMVIA runs all five stages for you, 24/7.

1. Assessment — We audit your current endpoint protection and identify gaps. 2. Deployment — Agents are rolled out across all endpoints with minimal disruption. 3. Configuration — Detection policies are tuned to your environment and risk profile. 4. Monitoring — Continuous monitoring by our SOC analysts, 24/7. 5. Optimisation — Ongoing tuning to cut false positives and sharpen detection.

This is the technology layer beneath our managed detection and response (MDR) service and our wider 24/7 security monitoring. EDR provides the signal; analysts provide the judgement.

Why do UK SMEs need EDR?

UK SMEs need EDR because attackers target the endpoint first and move fast — often within hours of initial access. The NCSC recommends EDR for meaningful attack targets, including UK SMEs in regulated sectors, because signature antivirus alone no longer stops ransomware, fileless malware or stolen-credential abuse.

EDR is also increasingly a condition of cyber insurance and of supply-chain security questionnaires. If you handle client data, process payments or sit in a regulated sector, "we have antivirus" is rarely an acceptable answer any more. EDR gives you the detection depth — and the audit trail — that both insurers and auditors expect. It pairs naturally with broader endpoint security controls such as device hardening and disk encryption.

EDR vs traditional antivirus: what's the difference?

EDR detects behaviour; antivirus detects known files. Antivirus is fast and cheap but blind to anything not already on a blocklist. EDR records and analyses endpoint activity, so it catches novel and fileless attacks — and lets an analyst trace exactly what an intruder did.
