When Pulse Stack™ monitors your websites and applications, our distributed network of servers sends regular health check requests. Some hosting providers and firewalls may block these legitimate monitoring requests, causing false downtime alerts.
To ensure accurate monitoring results, you'll need to configure your security systems to accept traffic from our monitoring infrastructure. This page provides all the necessary IP addresses and configuration guidance.
We provide multiple convenient ways to obtain our current monitoring server IP addresses:
Important Notice: Our monitoring infrastructure undergoes regular updates. We recommend using our API endpoint to ensure you always have the most current IP addresses for your firewall rules.
Pulse Stack™ employs a sophisticated multi-layered monitoring approach across four continental regions. Initial health checks originate from randomly selected servers within the same geographical area as your monitored service.
When potential issues are detected, our system immediately triggers verification checks from multiple independent servers and providers in the region. This methodology significantly reduces false positive alerts whilst maintaining rapid response times for genuine outages.

Below are practical examples for configuring popular firewall systems to accept Pulse Stack™ monitoring traffic:
Creating Allow Rules:
Accepting Traffic from Monitoring IPs:
sudo iptables -A INPUT -s [IP_ADDRESS] -j ACCEPT
Replace [IP_ADDRESS] with each Pulse Stack™ monitoring server IP. Save your configuration with sudo iptables-save.
Allow Monitoring Traffic:
sudo ufw allow from [IP_ADDRESS]
Execute this command for each monitoring server IP address in our lists.
Cisco ASA: Create access list entries permitting traffic from monitoring IPs to your monitored services.
Palo Alto Networks: Configure security policy rules with Pulse Stack™ IP ranges as source addresses.
Fortinet FortiGate: Add address objects for monitoring IPs and create corresponding firewall policies.
Check Point: Define network objects for Pulse Stack™ servers and configure access rules accordingly.
SonicWall: Create address objects and establish firewall rules permitting monitoring traffic.
