Shodan Monitor

Shodan Monitor is a continuous external attack surface management (ASM) and digital asset monitoring service designed to alert organizations whenever new internet-connected devices, unexpected open ports, or critical vulnerabilities are detected on their public IP network ranges. Modern organizations frequently experience perimeter blind spots caused by unauthorized cloud deployments, misconfigured developer firewalls, shadow IT infrastructure, and remote access systems exposed to the public internet. Shodan Monitor resolves this security vulnerability by actively tracking enterprise IP blocks, CIDR subnets, and cloud domains using Shodan's global scanning fleet. Whenever Shodan detects an unexpected change—such as an unauthenticated database, an exposed Remote Desktop Protocol (RDP) port, an unpatched zero-day vulnerability, or a compromised SSL/TLS certificate—it triggers automated real-time notifications via email, webhook, or Slack. Security teams can configure custom alert thresholds, suppress expected network services, and generate comprehensive perimeter audit reports. By providing an outside-in, attacker's perspective of public-facing assets without requiring software agents or intrusive scanning credentials, Shodan Monitor enables security teams to identify configuration drift, eliminate rogue network exposures, and secure their external perimeter.
