Remote work has become permanent infrastructure. Employees working from home need reliable network connectivity that doesn’t compromise security. Traditional approaches—either allowing unrestricted home internet access or requiring VPN clients on personal devices—create either security risks or user friction.
The Cisco Meraki Z3 teleworker gateway addresses this dilemma by providing a dedicated device for home office networking. Rather than relying on VPN software running alongside personal applications, the Z3 provides clean network connectivity designed specifically for business use while isolating home internet traffic. Understanding when and how to deploy Z3 gateways helps organizations support remote workers effectively without sacrificing security or user experience.
Understanding the Remote Work Challenge Remote work fundamentally changed how organizations approach networking and security.
The Problems with Traditional Remote Access
VPN Client Approach:
Adds software to personal computers
Runs alongside personal applications (security risk)
Requires user configuration and troubleshooting
Conflicts with personal VPN or security software
Performance impact on device
Support burden for home user experience
Unrestricted Internet Approach:
No protection from home internet threats
Employees’ personal browsing mixed with business
Home WiFi insecurity affects business traffic
No control over home network quality
Regulatory compliance risk
Both approaches create problems for organizations, IT teams, and remote workers.
The Z3 Advantage
The Meraki Z3 provides:
Dedicated business network – Separate from home internetAutomatic VPN – Z3 handles secure connectivity, no user configurationHome WiFi separation – Home internet and business traffic isolatedEnterprise security – Same protection as office networksSimple setup – Plug in and business connectivity worksBetter performance – Dedicated device doesn’t compete with home activities
Employees get secure, reliable business connectivity without technical complexity.
What Is the Meraki Z3? Z3 Architecture
The Meraki Z3 is a small office/home office (SOHO) networking device combining multiple security and connectivity functions:
Cisco Meraki security appliance functionalityWiFi access point for wireless devicesVPN gateway for secure connectivityCloud management through Meraki dashboard
Rather than being a simple WiFi router, the Z3 is a full security appliance in small form factor—suitable for individual home offices.
