Shodan Monitor tracks internet-connected devices across a network and sends real-time alerts when unexpected activity appears. Monitoring can start with one IP address or extend to events across the Internet. Inputs include IP addresses or network ranges, domains or hostnames, and search queries. Shodan continuously crawls monitored network ranges, and users can request an immediate scan or use its global infrastructure to check whether an issue has been fixed. It can help locate cloud data leaks, phishing websites, and compromised databases. Alerts can be sent by email, Slack, Microsoft Teams, Discord, Telegram, Gitter, PagerDuty, or webhooks. The service is also available through the Shodan API and command-line interface, with a streaming feed for programmatic access to network events. Domain and hostname DNS information refreshes every three hours, though coverage depends on Shodan DNS data. Membership costs 49.00 USD per once and covers up to 16 IPs; monthly plans include Freelancer at 69.00 USD per month and Small Business at 359.00 USD per month. Corporate costs 1099.00 USD per month and covers 327,680 IPs.
