Outbound Network Connections for Zen

Zen requires outbound internet access to function correctly.

During operation, Zen sends data to the following Aikido services:

EU-based domains:

guard.aikido.dev
runtime.aikido.dev

US-based domains:

guard.us.aikido.dev
runtime.us.aikido.dev

ME-based domains:

guard.me.aikido.dev
runtime.me.aikido.dev

Both domains use dynamic IPs managed by Aikido’s cloud infrastructure.

If your environment restricts outbound traffic, allow these domains by hostname rather than IP address.

Testing connectivity

Run these checks from the same host (and same container, if applicable) where your app runs. Substitute the regional domain that matches your account if you are not on the EU cluster.

Linux / macOS

# DNS resolution
nslookup guard.aikido.dev
nslookup runtime.aikido.dev

# HTTPS connectivity
curl -v https://guard.aikido.dev
curl -v https://runtime.aikido.dev

Windows (PowerShell)

Resolve-DnsName guard.aikido.dev
Test-NetConnection guard.aikido.dev -Port 443

If you use a proxy, corporate firewall, VPN, or SSL interception, verify that outbound traffic to *.aikido.dev on port 443 is allowed and that Aikido's certificates are not being rewritten. Proxy configuration is covered in Proxy & Load Balancer Settings.
