Securing Your Remote Workforce in 2026
Remote and hybrid working is now the norm for most UK businesses. The Office for National Statistics reports that around 40% of UK workers split their time between home and the office, while a further 16% work exclusively from home. That trend shows no sign of reversing. But with employees accessing company data from home networks, coffee shops, co-working spaces, and hotel Wi-Fi, the attack surface has expanded dramatically.
For IT leaders and business owners, the challenge is clear: how do you maintain strong security when your people and devices are scattered across dozens of locations? The answer lies in a layered approach that combines technical controls, clear policies, and ongoing education. Here is our comprehensive security checklist to keep your remote workforce protected in 2026.
The Evolving Threat Landscape for Remote Workers
Before diving into the checklist, it is worth understanding why remote work security deserves dedicated attention. Cyber criminals have adapted their tactics to target the specific vulnerabilities that remote and hybrid working creates. Phishing attacks impersonating IT helpdesk staff asking employees to "re-authenticate" have surged. Man-in-the-middle attacks on public Wi-Fi networks continue to catch out users who assume their local coffee shop connection is safe. And the blurring of personal and professional device usage creates additional entry points for attackers.
The UK National Cyber Security Centre (NCSC) has repeatedly highlighted remote working as a key risk area for organisations of all sizes. Their guidance emphasises that businesses need to assume employees will sometimes work from insecure locations and design their cyber security strategy accordingly. With that context in mind, let us walk through the essential controls.
Your Remote Work Security Checklist
1. Enforce Multi-Factor Authentication (MFA) Everywhere
MFA remains the single most effective security control you can implement. Microsoft reports that MFA blocks over 99.9% of account compromise attacks, making it arguably the highest-impact security measure available relative to its cost and complexity. Every user accessing company resources - whether email, cloud applications, VPN, or line-of-business systems - should be required to verify their identity with at least two factors.
Microsoft Entra ID (formerly Azure AD) makes it straightforward to enforce MFA across your entire Microsoft 365 tenant. We recommend using the Microsoft Authenticator app or FIDO2 security keys rather than SMS-based verification, which is vulnerable to SIM-swapping attacks. For organisations with higher security requirements, consider implementing number matching in the Authenticator app, which requires users to enter a number displayed on the sign-in screen rather than simply tapping "Approve." This significantly reduces the risk of MFA fatigue attacks, where criminals bombard users with authentication prompts until they approve one out of frustration.
Quick wins: Enable security defaults in Microsoft Entra ID if you have not already. This enforces MFA for all users at no additional cost. For more granular control, Conditional Access policies allow you to require MFA based on location, device state, or risk level.
2. Deploy a Business-Grade VPN or Zero Trust Network Access
A Virtual Private Network encrypts all traffic between your employees' devices and your corporate network. This is essential when staff connect via public Wi-Fi or untrusted networks. Modern always-on VPN solutions ensure protection is active without requiring user intervention, removing the risk of employees forgetting to connect. For organisations using Azure, Azure VPN Gateway provides a seamless experience integrated with your cloud infrastructure.
However, many organisations are now moving beyond traditional VPN towards a Zero Trust Network Access (ZTNA) model. Rather than granting access to the entire corporate network once a user connects, ZTNA provides access only to specific applications based on the user's identity, device health, and context. This limits the blast radius if an attacker does compromise a device, because they cannot move laterally through your network. Microsoft Entra Private Access and solutions like Zscaler Private Access are leading options in this space.
Whichever approach you choose, the key is ensuring that remote connections are encrypted and authenticated. Split tunnelling - where some traffic bypasses the VPN - should be carefully evaluated. While it can improve performance for cloud applications, it may expose sensitive traffic to interception on untrusted networks.
3. Implement Comprehensive Endpoint Protection
Every device that accesses company data needs robust endpoint protection. Traditional antivirus is no longer sufficient against modern threats. Microsoft Defender for Endpoint provides enterprise-grade protection with threat detection, automated investigation, and remediation capabilities. It uses behavioural analysis and machine learning to identify threats that signature-based tools would miss, including fileless malware and zero-day exploits.
Ensure all devices are enrolled in your endpoint management platform, such as Microsoft Intune, so you can enforce security policies, push updates, and remotely wipe devices if they are lost or stolen. Intune also allows you to set compliance policies that gate access to company resources. For example, you can require that a device has encryption enabled, is running a supported operating system version, and has up-to-date antivirus before it can access corporate email or SharePoint.
For organisations that allow personal devices (BYOD), consider using Intune's app protection policies to create a managed container for company data without requiring full device enrolment. This protects business data while respecting employee privacy on their personal devices.
4. Establish a Clear Remote Working Policy
Technical controls are only part of the solution. Your staff need clear guidance on acceptable use, data handling, and incident reporting. A well-drafted remote working policy sets expectations and gives employees the confidence to do the right thing. Your policy should cover:
Approved devices and software - Specify which devices can be used for work, whether personal devices are permitted, and which applications are approved for business use.
Password and authentication requirements - Minimum password length, complexity rules, and the requirement to use MFA.
Physical security - Locking screens when stepping away, not leaving devices unattended in public, and securing equipment at home.
Data handling - Where to save files, how to handle sensitive information, rules around printing confidential documents at home, and restrictions on using USB drives.
Incident reporting - Clear procedures for reporting suspected breaches, phishing emails, lost devices, or any other security concerns. Make it easy and judgement-free so staff report issues quickly rather than hiding mistakes.
Regular security awareness training helps reinforce these policies and keeps cyber security front of mind. Short, frequent training sessions are far more effective than annual tick-box exercises. Consider using simulated phishing campaigns to test awareness and identify staff who need additional support.
5. Provide Secure Home Network Guidance
Your employees' home networks are part of your security perimeter whether you like it or not. While you cannot manage every home router, you can provide clear guidance that significantly reduces risk. A simple one-page guide sent to all remote workers can cover the essentials:
Change default router admin passwords - many home routers ship with well-known default credentials that are trivially easy for attackers to exploit.
Enable WPA3 encryption (or WPA2 at minimum) and set a strong Wi-Fi password.
Keep router firmware updated - manufacturers regularly release patches for security vulnerabilities.
Separate work devices from IoT devices (smart speakers, cameras, thermostats) using guest networks or VLANs where possible. IoT devices are notoriously insecure and can provide a foothold into the home network.
Disable WPS (Wi-Fi Protected Setup) as it has known security weaknesses.
Some organisations go further by providing pre-configured routers or access points for key staff, ensuring a baseline level of network security regardless of the employee's existing home setup. A small investment in employee education and equipment here pays significant dividends in reducing risk.
6. Enforce Regular Patching and Updates
Unpatched software remains one of the most exploited attack vectors. The NCSC reports that many successful cyber attacks exploit vulnerabilities for which patches have been available for months or even years. When devices are outside the corporate network, it becomes even more critical to have a reliable patching strategy.
Use your endpoint management solution to enforce automatic updates for operating systems, browsers, and business applications. Microsoft Intune can manage Windows Update rings, ensuring devices receive patches on a schedule that balances security with business continuity. Establish a clear patching cadence: critical and high-severity patches should be deployed within 48 hours of release, while lower-severity updates can follow a weekly or monthly cycle.
Do not forget about third-party applications. Tools like Adobe Acrobat, Zoom, and browser plugins are frequently targeted and need to be included in your patching regime. Consider using a patch management solution that covers both Microsoft and third-party applications to ensure nothing falls through the cracks.
7. Implement Data Loss Prevention (DLP) Controls
When employees work remotely, the risk of data leaving your organisation increases. Files might be saved to personal cloud storage, emailed to personal accounts, or copied to USB drives. Microsoft Purview Data Loss Prevention provides policies that can detect and prevent sensitive information from being shared inappropriately, whether via email, Teams, SharePoint, or endpoint devices.
Start by classifying your most sensitive data - financial records, customer personal data, intellectual property, and HR information are common starting points. Then create DLP policies that alert or block when this data is being shared outside approved channels. For most UK businesses, this is also an important part of demonstrating UK GDPR compliance, as the regulation requires appropriate technical measures to protect personal data.
8. Secure Collaboration Tools
Microsoft Teams, Zoom, and other collaboration platforms are the backbone of remote work, but they also introduce security considerations. Ensure that external sharing settings are configured appropriately - you do not want employees inadvertently adding external users to internal Teams channels. Review guest access policies regularly and remove external guests who no longer need access.
For sensitive meetings, consider using Teams meeting options to control who can bypass the lobby, who can present, and whether recording is permitted. Sensitivity labels can be applied to Teams and SharePoint sites to enforce appropriate controls based on the classification of information being discussed or stored.
9. Plan for Device Loss and Theft
Laptops get stolen from cars, left on trains, and forgotten in coffee shops. It happens, and your security strategy needs to account for it. Ensure all devices have full disk encryption enabled - BitLocker for Windows, FileVault for Mac. This means that even if a device falls into the wrong hands, the data on it remains inaccessible without the correct credentials.
With devices enrolled in Intune, you can remotely wipe a lost or stolen device, removing all company data. You should also have a clear process for employees to report lost devices immediately so that action can be taken quickly. Every hour of delay increases the risk. Consider implementing managed IT support with a 24/7 helpdesk so that device loss can be reported and acted upon outside business hours.
10. Monitor and Audit Remote Access
You cannot secure what you cannot see. Implement logging and monitoring for all remote access to your systems. Microsoft Entra ID sign-in logs provide valuable visibility into who is accessing what, from where, and on which device. Set up alerts for suspicious activity, such as sign-ins from unusual locations, impossible travel scenarios (where a user appears to sign in from two distant locations within minutes), or sign-ins from devices that are not compliant with your policies.
For organisations with more advanced requirements, Microsoft Sentinel provides a cloud-native SIEM (Security Information and Event Management) solution that can correlate signals across your entire environment and automatically respond to threats. Even without a full SIEM deployment, regular review of sign-in logs and audit trails is an important part of maintaining a strong security posture.
Putting It All Together: A Practical Approach
If you are reading this checklist and feeling overwhelmed, take a breath. You do not need to implement everything at once. The key is to prioritise based on risk and build your remote security posture incrementally. If we had to pick the three most impactful measures for a business starting from scratch, they would be:
Enable MFA for all users - This single control blocks the vast majority of credential-based attacks.
Enrol devices in endpoint management - Gives you visibility and control over the devices accessing your data.
Encrypt all devices - Protects data at rest if a device is lost or stolen.
From there, you can layer in VPN or ZTNA, DLP policies, advanced monitoring, and the other controls outlined above. Each layer adds resilience and makes your organisation a harder target for attackers.
