Executive Briefing
Protect your business when employees work from home, cafes, or co-working spaces. Implement practical security controls without killing productivity.
The Remote Work Security Challenge
Remote work introduces risks that didn't exist when everyone worked in the office:
- Home networks lack enterprise-grade security controls
- Shared devices and spaces increase exposure risk
- VPN and cloud access create new attack vectors
- IT visibility decreases—you can't see what you can't monitor
- Social engineering attacks exploit the isolation of remote workers
12 Essential Security Practices for Remote Teams
1. Enforce Multi-Factor Authentication Everywhere
MFA is non-negotiable for remote access. Enable it for all cloud services, VPNs, and remote desktop connections. Use authentication apps rather than SMS where possible.
2. Implement Conditional Access Policies
Use Conditional Access in Microsoft 365 to require additional verification based on risk signals—unusual locations, unrecognised devices, or risky sign-in behaviour.
3. Deploy Endpoint Detection and Response (EDR)
Install EDR solutions on all work devices. Microsoft Defender for Endpoint provides real-time threat detection and response capabilities, regardless of where the device is located.
4. Use a VPN or Zero Trust Network Access
For accessing on-premises resources, require VPN connections. Better yet, implement Zero Trust Network Access (ZTNA) that verifies every connection request regardless of network location.
5. Enforce Device Encryption
Require BitLocker (Windows) or FileVault (Mac) on all devices containing business data. If a laptop is lost or stolen, encryption protects your data.
6. Implement Mobile Device Management (MDM)
Use Microsoft Intune or similar MDM to enforce security policies, deploy updates, and remotely wipe lost devices. You need control over devices accessing your data.
7. Secure Home Network Guidance
Provide employees guidance on securing home networks: change default router passwords, enable WPA3 encryption, update router firmware, and consider network segmentation.
8. Deploy DNS Filtering
Cloud-based DNS filtering blocks access to malicious websites regardless of location. Tools like Cisco Umbrella or Microsoft Defender for Endpoint provide this protection.
9. Establish Clear BYOD Policies
If employees use personal devices, define what's required: minimum security configurations, acceptable use, and your rights to manage or wipe company data.
10. Regular Security Awareness Training
Remote workers face increased phishing and social engineering attacks. Monthly security awareness training and simulated phishing helps maintain vigilance.
11. Secure Collaboration Tools
Configure Microsoft Teams, SharePoint, and other collaboration tools securely. Control external sharing, guest access, and data loss prevention policies.
12. Establish Incident Reporting Procedures
Remote workers need clear channels to report security concerns. Make it easy to report suspected phishing, lost devices, or unusual account activity—without fear of blame.
Important Note
Key principle: Security shouldn't impede productivity. Controls that frustrate users get circumvented. Design security that's as frictionless as possible while maintaining protection.
Physical Security for Remote Workers
Security isn't just digital:
- Screen privacy: Use privacy screens in public spaces
- Device security: Never leave devices unattended in public
- Secure workspace: Lock screens when stepping away, even at home
- Voice security: Be aware of who can overhear confidential calls
- Document handling: Securely dispose of printed documents

Frequently Asked Questions
Company-owned devices provide more control and security. However, many SMBs allow BYOD with proper policies and MDM enrollment. The key is maintaining control over company data regardless of device ownership.
If all resources are cloud-based with proper security (MFA, Conditional Access), VPN may not be necessary. However, VPN or ZTNA is essential for accessing on-premises resources or adding an additional security layer.
Use centralised monitoring tools: Microsoft 365 security dashboards, Intune compliance reports, EDR alerts, and cloud access security brokers (CASBs). You need visibility into device health, sign-in patterns, and security events.
Cover device requirements, acceptable use, network security expectations, incident reporting, physical security, and consequences for policy violations. Keep it practical and enforceable rather than aspirational.
