Remote and hybrid work isn't a pandemic experiment anymore. It's how business gets done. But for many organizations, the security posture hasn't caught up with the reality of where and how employees actually work.
The problem isn't that leaders don't care about remote security. It's that they're solving for the wrong things, or assuming their existing controls are enough.
Key insight: Most remote work security strategies were built as temporary fixes in 2020 and never revisited. The threat landscape has changed dramatically since then, but many organizations are still relying on VPN access and hope.
Here are the five most common mistakes leaders make with remote work security, and what to do instead.
Mistake 1: Thinking VPN Solves Everything
A VPN creates an encrypted tunnel between your employee's device and your network. That's useful, but it's not a security strategy. A VPN doesn't protect against:
- Malware already on the employee's device
- Phishing attacks that steal credentials
- Data exfiltration through cloud services
- Compromised home networks
Many organizations treat VPN as a security perimeter, but in a remote work world, there is no perimeter. Your employees access data from home Wi-Fi, coffee shops, airport lounges, and coworking spaces. The VPN protects the pipe, but not the endpoints or the people.
What to do instead: Adopt a zero-trust mindset. Verify every user and device at every access request. Deploy endpoint protection on all company devices. Use conditional access policies that evaluate risk signals before granting access.
Mistake 2: Ignoring Home Network Risks
Your employee's home router is probably running default firmware from three years ago with a password of "admin." Their smart home devices share the network with their work laptop. Their teenager's gaming PC might be running software downloaded from questionable sources.
You can't control home networks, but you can mitigate the risk:
- Require company-managed devices for accessing business systems. Personal devices should not have direct access to sensitive data.
- Deploy DNS-level filtering that travels with the device, not the network.
- Provide guidance on basic home network hygiene: change default router passwords, update firmware, segment networks if possible.
The BYOD Blind Spot
If employees access company email and files on personal devices, you have limited visibility and no control over those devices. Every personal phone checking work email is an unmanaged endpoint connected to your data. Either provide company devices or deploy mobile device management (MDM) on personal devices with clear BYOD policies.
Mistake 3: Underestimating Shadow IT
When employees work from home, they find workarounds. The approved file-sharing platform is too slow, so they use a personal Dropbox. The project management tool doesn't have a feature they need, so they sign up for a free alternative. A team starts using WhatsApp for quick communication because Slack feels too formal.
Each of these shadow IT decisions creates an unmonitored, unmanaged data flow outside your security controls. Sensitive information ends up in systems you don't even know about.
Data point: The average mid-sized company has 3-4x more SaaS applications in active use than IT is aware of. Each unsanctioned application represents an unmanaged risk surface. -Productiv SaaS Intelligence Report
What to do instead: Make the approved tools work well. If employees are going around your systems, the problem is usually usability, not malice. Conduct a periodic SaaS audit. Ask employees what tools they're using and why. Then either bring those tools under management or provide better alternatives.
Mistake 4: Treating Security Training as a One-Time Event
Annual security awareness training was barely adequate when everyone worked in the same building. In a remote environment, it's even less effective. Remote employees face unique threats:
- Phishing emails are harder to verify without a colleague to ask
- Home distractions increase the likelihood of careless clicks
- The informal "Hey, did anyone else get this weird email?" hallway conversation doesn't happen remotely
What to do instead: Shift to continuous, micro-learning formats. Short monthly modules. Regular phishing simulations. Quick tips delivered through the tools employees already use. Make security awareness part of the work rhythm, not an annual checkbox.
Mistake 5: No Visibility into Remote Endpoints
If you can't see it, you can't protect it. Many organizations have limited visibility into what's happening on remote devices, whether patches are current, whether antivirus is running, whether unauthorized software has been installed.
What to do instead: Deploy an endpoint management solution that provides real-time visibility into device health, patch status, and security compliance. This should be non-negotiable for any device that accesses company data.
The combination of endpoint detection and response (EDR) with a device management platform gives you the visibility you need without requiring employees to come to the office for IT checkups.
Key Takeaways
- VPN is not a security strategy, Move toward zero trust with device-level verification
- Home networks are uncontrolled environments, Require managed devices and endpoint protection
- Shadow IT is a symptom, not the disease, Fix the usability gap before the security gap
- Annual training is not enough, Remote workers need continuous, bite-sized security education
- Visibility is non-negotiable, If you can't see your endpoints, you can't protect them
Remote work is permanent. Your security controls need to be permanent too, not the temporary patches deployed three years ago. For a comprehensive guide to securing a distributed workforce, see Cybersecurity for CEOs.
