Endpoint Security for Remote and Hybrid Workers
Remote and hybrid workers use business devices outside the corporate network — connecting from home broadband, public Wi-Fi, and personal networks that lack the security controls of an office environment. Endpoint security must travel with the device, not rely on network perimeter controls.
Overview
Remote workers connect from networks outside corporate control — security must be device-centric, not network-dependent. Microsoft Intune manages devices remotely, Defender for Business provides endpoint protection wherever the device connects, and Conditional Access enforces MFA and device compliance regardless of location. 43% of UK businesses experienced a breach in 2025 (DSIT).
Learn about zero trust securityIt is delivered as part of AMVIA's managed cybersecurity service and sits inside the wider endpoint security discipline. The principle is simple: when the office perimeter disappears, the device becomes the perimeter — so every laptop, phone and tablet must carry its own protection, encryption and access controls wherever it travels.
How does remote worker endpoint security work?
Remote worker endpoint security applies controls directly to the device and to every access request, not to a corporate network the device rarely touches. Each endpoint is managed, encrypted and monitored from the cloud, and access to business data is granted only when the device proves it is compliant.
Three Microsoft technologies do the heavy lifting:
- Microsoft Intune — manages devices over the internet: pushing security settings, patches, encryption and remote wipe without the device ever touching the office network.
- Microsoft Defender for Business — endpoint detection and response (EDR) that monitors and contains threats on the device itself, wherever it connects.
- Conditional Access — checks identity, device compliance and sign-in risk before granting access to Microsoft 365, blocking anything that fails.
Because all three are cloud-delivered, a laptop on hotel Wi-Fi is governed by exactly the same rules as one plugged in at head office. The UK's National Cyber Security Centre recommends this device-led model in its home and remote working guidance.
Why do UK SMEs need remote worker endpoint security?
Hybrid work moved business data outside the firewall faster than most security models could follow. Devices now connect from networks no IT team controls, the attack surface has widened, and a single lost or compromised laptop can expose a whole organisation. The numbers make the risk concrete.
- "43% of UK businesses experienced a cybersecurity breach or attack in the past twelve months" (DSIT Cyber Security Breaches Survey 2025).
- "28% of UK employees now work in a hybrid pattern, splitting time between home and the office" (ONS, 2025).
- "The average cost of a data breach for UK organisations was £3.58 million (IBM Cost of a Data Breach Report, 2024)".
- "Only 14% of UK businesses have a formal incident response plan" (DSIT Cyber Security Breaches Survey 2025).
Remote workers also face risks office staff largely avoid: home routers with default passwords and stale firmware, public Wi-Fi exposed to man-in-the-middle attacks, and isolation that makes phishing easier to fall for without a colleague to sense-check a suspicious email. Device-level controls are what close that gap.
VPN vs Zero Trust Network Access — which fits a cloud-first SME?
For most Microsoft 365 businesses, a traditional VPN is no longer the right primary remote-access tool. A VPN drops the user inside the network and grants broad access; Zero Trust Network Access (ZTNA) grants access to specific apps only after verifying identity, device compliance and risk on every request. Conditional Access gives M365 customers ZTNA-style control with no extra product.
| Factor | Traditional VPN | Conditional Access (ZTNA-style) |
|---|---|---|
| Trust model | Implicit — on the network = trusted | Zero trust — every request verified |
| Access scope | Broad network access | Per-application, least privilege |
| Device compliance check | Usually none | Required before access granted |
| Performance | Routes cloud traffic through HQ | Direct to cloud, no bottleneck |
| Best for | Legacy on-premises apps and file servers | Microsoft 365, Teams, SharePoint, OneDrive |
A VPN may still be needed for specific on-premises systems that have not moved to the cloud — but it should not be the default front door for a workforce that lives in Microsoft 365. This is the zero trust principle applied to remote access.
What does AMVIA's remote endpoint security include?
AMVIA enrols every managed device in Intune, configures Defender for Business with EDR, deploys Conditional Access policies, and sets BYOD rules — then manages it all centrally so protection is identical whether your team is in the office or at home. You get a single accountable provider rather than a stack of disconnected tools.
| Capability | Unmanaged / DIY | AMVIA-managed |
|---|---|---|
| Device enrolment | Ad hoc, often skipped | Every endpoint in Intune |
| Disk encryption | Inconsistent | BitLocker enforced by policy |
| Threat detection | Basic antivirus | Defender for Business EDR, monitored |
| Access control | Password only | MFA + device-compliance Conditional Access |
| Lost-device response | Manual, slow | Documented remote wipe via Intune |
BYOD is handled two ways through Intune: full enrolment where staff consent, or Mobile Application Management (MAM) that protects only business apps and data — enforcing encryption, blocking copy-paste to personal apps, and enabling selective wipe without touching personal content. For field staff, the same controls extend to phones and tablets through mobile device management.
How much does remote worker endpoint security cost?
Most of the controls ship inside Microsoft 365 Business Premium, which lists at £16.90 per user, per month (ex VAT, annual commitment) on microsoft.com/en-gb. That single licence includes Intune, Defender for Business and Conditional Access — the full remote endpoint stack — so the technology cost is predictable and per-user.
AMVIA's management fee is quoted on top of licensing and depends on device count and scope. The licence is the platform; the value is in correct configuration, monitoring and response — which is what separates a Business Premium subscription you own from an endpoint estate that is actually secured. AMVIA's hybrid-working configuration is detailed in our M365 hybrid working security guidance.
Key Points
What UK businesses need to know about securing remote workers.
Network Perimeter Is Gone
Remote workers are not on the corporate network. Firewall and perimeter security tools do not protect devices that are not connected through them.
Device-Centric Security
Security must be applied to the device itself — endpoint protection, device management, encryption — not to the network the device happens to be on.
Conditional Access Enforces Compliance
Microsoft Conditional Access blocks non-compliant or unmanaged devices from accessing M365 — regardless of where the user is connecting from.
Phishing Risk Is Higher for Remote Workers
Remote workers are more isolated from informal security culture and may be more susceptible to phishing — making technical email security and training more important.

MFA enforced for all Microsoft 365 accounts
Conditional Access requires device compliance before M365 access
Remote wipe procedure documented — staff know who to contact if device is lost
Frequently Asked Questions
For most businesses on Microsoft 365, a traditional VPN is not needed for daily work. Teams, SharePoint and OneDrive are cloud services reached directly over the internet with MFA and Conditional Access. A VPN is only required for specific on-premises resources — internal databases or legacy file servers — that have not migrated to the cloud.
A managed laptop with BitLocker encryption keeps its data inaccessible without valid credentials. AMVIA triggers a remote wipe through Intune, revokes the user's Microsoft 365 sessions and forces a password reset so stolen credentials cannot be reused. These steps are pre-documented in AMVIA's lost-device procedure, so response is immediate rather than improvised.
With device-centric security, the home network matters far less. Defender for Business network protection blocks malicious domains regardless of the Wi-Fi in use, BitLocker protects data if the device is lost, and Conditional Access stops non-compliant devices reaching company data. Basic router hygiene — changing default passwords, using WPA3 — still helps but is not the primary control.
Through Microsoft Intune. Full enrolment applies corporate management where staff agree; Mobile Application Management protects only business apps and data on a personal device — enforcing encryption and selective wipe without affecting personal content. A written BYOD policy defines what data personal devices can reach and what happens when someone leaves.
Intune, Defender for Business and Conditional Access are built into Microsoft 365 Business Premium and work together natively — one identity, one policy engine, one console. That avoids the gaps and overlap of bolting on third-party agents, keeps licensing simple, and gives AMVIA a single platform to manage and monitor across every remote endpoint.
Defender for Business provides strong EDR, but tools do not equal protection. Alerts still need someone to triage, contain and respond to them. AMVIA's in-house team monitors Defender across your estate and acts on detections — turning the technology into an actual managed service rather than a dashboard nobody is watching.
