Every Unprotected Device Is a Door Left Wide Open

This page sits under our managed cybersecurity pillar, where endpoints are one layer of a full security stack covering email, network, and 24/7 monitoring.

What is endpoint security?

Endpoint security is the protection of every device — an "endpoint" — that connects to your network. Each laptop, server, or phone is a potential entry point for attackers. Modern endpoint security uses EDR to monitor process behaviour live, contain compromised devices, and give forensic investigators a full activity trail.

For UK businesses with hybrid teams, the endpoint is now the security perimeter. Office staff sit behind a corporate firewall; remote workers connect from home broadband, hotels, and public Wi-Fi the business cannot control. If one device is breached, attackers use it as a beachhead to reach other systems, steal data, or deploy ransomware.

• 99%+ threat detection rate for modern EDR vs 60–70% for traditional signature-based antivirus (independent lab testing, 2026)
• 1,200+ UK business endpoints monitored by AMVIA's security operations centre

What does AMVIA's managed endpoint security include?

AMVIA's service combines Microsoft Defender for Endpoint — Microsoft's enterprise EDR platform — with our in-house 24/7 SOC. You get the detection technology and the human analysts who investigate and respond, under one contract with one provider accountable for the outcome.

• EDR deployment and management — Defender for Endpoint rolled out across every device, with continuous tuning to cut false positives.
• 24/7 monitoring — our security operations centre investigates alerts around the clock and escalates genuine threats, with monthly reporting.
• Threat containment — analysts isolate affected devices within minutes to stop lateral movement and limit blast radius.
• Patch management — automated OS and third-party patching with a 14-day remediation target for critical vulnerabilities.
• Remote and mobile cover — home-worker laptops and phones are managed via Microsoft Intune, enforcing encryption, PIN policies, and selective wipe.

How does EDR differ from traditional antivirus?

Traditional antivirus compares files against a database of known malware signatures: match a known-bad file and it blocks it, miss it and the threat passes through. EDR instead watches the live behaviour of every process, catching novel ransomware, fileless attacks, and living-off-the-land techniques that signatures never see.

Ransomware operators routinely modify malware to dodge signatures, fileless malware runs entirely in memory, and attackers abuse legitimate tools like PowerShell and WMI. Signature scanning is blind to all three. The NCSC's device security guidance sets out why behavioural protection and prompt patching matter for every managed device.

EDR does not just detect — it responds, automatically isolating the endpoint, killing malicious processes, and rolling back changes within seconds. Read our endpoint detection and response breakdown for the full technical detail.

Managed endpoint security vs self-managed: which is right for you?

EDR tools are powerful but noisy — they generate high alert volumes, many of them false positives. Without a dedicated investigation team, real threats get lost in the noise. Self-managing works for organisations with 200+ staff and a genuine in-house security function; for most SMEs the IT team is generalist and stretched.

Managed endpoint security — also called Managed Detection and Response (MDR) — hands monitoring, investigation, and response to a provider. AMVIA pairs Defender for Endpoint with our managed detection and response team, delivering enterprise EDR with human-led response at lower cost than an understaffed internal rota.

How are remote and hybrid workers protected?

Remote devices connect from networks the business cannot control, so they need identical protection to office machines. AMVIA's Defender for Endpoint agents report to a cloud console regardless of location, so our SOC monitors a home laptop exactly as it does an office desktop.

• Encryption — full disk encryption enforced via BitLocker (Windows) and FileVault (macOS), so a lost device exposes no data.
• Patching — remote machines are patched as promptly as on-site infrastructure, closing the most-exploited vulnerability class.
• Monitoring and isolation — if a remote device is compromised, analysts isolate it from corporate resources within minutes, even on a home network.

Pair this with 24/7 security monitoring for continuous coverage across your whole estate.

How much does managed endpoint security cost?

Managed endpoint security for UK SMEs typically costs between £8 and £20 per device per month (typical UK 2026 range), depending on scope. That usually covers the Defender for Endpoint licence, managed detection and response, SOC monitoring and alert investigation, patch management, and monthly reporting.

Weigh that against a single incident. Recovery from a breach mounts up fast once downtime, remediation, and data recovery are added together — and the Cyber Security Breaches Survey 2025 puts the average cost of the most disruptive breach for UK businesses at £3,550 (gov.uk). Endpoint protection is one of the highest-return security investments a UK business can make.

How do you choose an endpoint security provider?

Judge providers on four things: do they run their own SOC, what tooling do they use, what is the response SLA, and do they cover remote and mobile devices. AMVIA operates its own UK SOC, uses Microsoft Defender for Endpoint and Barracuda, guarantees one-hour response to critical endpoint incidents 24/7, and covers home and mobile devices as standard.

• Own SOC — AMVIA's SOC is UK-based, not white-labelled offshore.
• Enterprise tooling — Microsoft Defender for Endpoint and Barracuda, backed by Microsoft's security platform.
• Accountable credentials — Cyber Essentials Plus certified and a Microsoft Solutions Partner (Modern Work, Security & Azure Infrastructure).
