Managed Endpoint Security for UK Small Businesses

This is a core service within our managed cybersecurity practice. Endpoints are where most attacks land — a single unpatched laptop or stolen credential is often all an attacker needs. With 43% of UK businesses experiencing a cyber breach in 2025 (gov.uk Cyber Security Breaches Survey 2025), leaving devices on consumer antivirus is no longer a defensible position.

What is managed endpoint security?

Managed endpoint security means an external security team owns the protection of every device on your network — deploying agents, writing detection policies, patching software, and responding to threats — instead of leaving it to an overstretched internal IT person. It moves you from "we installed antivirus once" to continuous, monitored defence.

It typically combines several layers most businesses run separately, or not at all:

• Next-generation antivirus (EPP) — behavioural detection that catches malware traditional signature antivirus misses.
• Endpoint detection and response — records device activity so analysts can investigate and roll back attacks.
• Patch management — operating system and third-party app updates on a defined schedule.
• Encryption and policy enforcement — BitLocker, firewall, password and access baselines applied consistently.
• 24/7 monitoring — agents watched by a SOC, not just a dashboard nobody checks.

What is included in AMVIA's managed endpoint security?

AMVIA's service covers the full lifecycle of every endpoint: audit, deployment, configuration, monitoring and response. We run Microsoft Defender for Endpoint as the core agent — a tool defined as Microsoft's enterprise endpoint protection platform — and tune it to your environment so alerts are real, not noise.

Every engagement includes:

• Proactive protection — continuous monitoring and threat detection to stop incidents before they spread.
• Expert management — UK-based engineers handle configuration, updates and incident response, so your team doesn't have to.
• Regular reporting — monthly reports on security posture, incidents handled and recommended improvements.
• Dedicated support — direct access to your account team for questions, changes and escalations.

For tighter Microsoft 365 control, we pair endpoint protection with Microsoft Defender for Business and Microsoft Intune device management for policy enforcement across managed and mobile devices.

How does AMVIA protect your endpoints?

We follow a four-stage process that takes you from an unknown device estate to a fully monitored, baseline-compliant fleet. It is designed to deploy quietly, without disrupting staff, then hand you continuous protection backed by our 24/7 security monitoring team.

1. Device audit — we inventory all endpoints (laptops, desktops, servers) and assess current protection levels and patch status. 2. Agent deployment — endpoint protection agents are deployed silently across your estate with policies matched to your risk profile. 3. Policy configuration — detection rules, exclusions and response actions are tuned to your environment to minimise false positives. 4. Continuous monitoring — 24/7 monitoring with automated threat response, monthly reports and regular policy reviews.

Why do UK SMEs need managed endpoint security?

UK SMEs need managed endpoint security because devices are now the front line, attackers automate against small businesses, and most internal teams cannot watch every endpoint 24/7. Hybrid work has pushed laptops outside the office firewall, widening the attack surface that legacy antivirus was never built to defend.

The numbers make the case plainly:

• 43% of UK businesses experienced a cyber breach in 2025 (gov.uk Cyber Security Breaches Survey 2025).
• 85% of breaches involved phishing (DSIT 2025) — and phishing payloads execute on the endpoint.
• £3,550 is the average cost of a disruptive breach for UK businesses.
• 19,000 UK businesses were hit by ransomware in 2025 (Sophos State of Ransomware 2025).
• Only 40% of UK businesses have two-factor authentication enabled (DSIT 2025).

The NCSC's device security guidance is clear that patching, encryption and managed configuration are baseline controls — exactly what a managed service enforces consistently.

In-house antivirus vs managed endpoint security

The difference is not the software — it is who runs it, watches it, and responds when something fires at 2am. The table below sets out the practical contrast.

Why choose AMVIA for managed endpoint security?

AMVIA combines accredited security credentials, a UK-based team and a 1,200-business track record. We are a security partner, not a telecoms reseller bolting on antivirus — endpoint protection is part of how we run security-first managed services for SMEs.

• Sheffield-based, UK-focused — our engineering and support team operates from Sheffield and understands UK compliance, infrastructure and the threats facing British businesses.
• Accredited and certified — AMVIA holds Cyber Essentials Plus certification and Microsoft Solutions Partner status (Modern Work, Security and Infrastructure).
• 1,200+ UK businesses protected — across legal, finance, healthcare and professional services.
• Fast, responsive support — critical issues responded to within one hour, by phone, email and portal, with dedicated account managers who know your environment.

How much does managed endpoint security cost?

AMVIA's managed endpoint security starts from £1.89 per device per month, billed per endpoint so the cost scales with your fleet rather than a fixed platform fee. Pricing depends on device count, the policy tier you need, and whether you bundle EDR, patching and reporting together.
