Securing Remote Work
Remote work erased the network perimeter for good. When employees connect from home networks, cafés, and personal devices, “inside the office = trusted” stops meaning anything. Securing a distributed workforce is therefore less about the network and more about identity, device health, and data — the same shift that zero trust describes, forced by reality.
What changed, and what it demands#
| Old assumption | Remote reality |
|---|---|
| Trusted office network | Untrusted home/public networks |
| Managed devices on-site | Mixed personal and corporate devices |
| Physical security | Devices anywhere, easily lost |
| Perimeter-based access | Access from everywhere |
Each broken assumption points to a control: since location no longer implies trust, every access must be earned by identity and device health.
The practical controls#
- Strong, phishing-resistant MFA on every access.
- Device posture checks — is the connecting device patched, encrypted, running required protection? — via NAC or similar.
- Endpoint hardening and EDR on the devices themselves.
- Encryption of data at rest and in transit.
- Zero trust — verify each access, do not trust the network or a VPN alone.
Securing remote work is zero trust applied to a distributed workforce. More at the Defense & Hardening hub.
Frequently asked questions#
What are the main security challenges of remote work?
Remote work removes the network perimeter: devices connect from untrusted networks, personal and home devices may access corporate resources, and physical security varies. The challenges are ensuring device health, authenticating strongly regardless of location, protecting data outside the office, and maintaining visibility over a distributed environment.
How do you secure a remote workforce?
With identity-centric controls: strong (ideally phishing-resistant) MFA, device posture checks before granting access, endpoint hardening and EDR, encryption of data at rest and in transit, and a zero-trust approach that verifies every access rather than trusting the network. VPNs help for access but are not sufficient on their own.
