Network downtime costs businesses thousands of pounds every hour. When TCP ports become unavailable, your critical services fail silently until users start complaining. Pulse Stack™ eliminates this risk by continuously monitoring your TCP connections and alerting you the moment issues arise.
Our intelligent monitoring system checks your network endpoints every 60 seconds, ensuring you discover problems before they impact your customers.
Monitor any TCP port on your servers and network devices with precision. Our platform supports all standard ports including:
Each monitor tracks response times, connection success rates, and provides detailed performance metrics to help you optimise your infrastructure.
When port monitoring detects an issue, Pulse Stack™ immediately sends alerts through your preferred notification methods:
Pulse Stack™ provides enterprise-grade features to prevent false alarms and streamline your monitoring workflow:
Prevent service disruptions - Detect port failures before they affect users and maintain high availability across all your network services.
Reduce support workload - Proactive monitoring means fewer emergency calls and complaints from frustrated users experiencing connection issues.
Improve response times - Get immediate alerts when performance degrades, allowing you to investigate and resolve problems quickly.
Maintain user satisfaction - Consistent service availability keeps customers happy and protects your organisation's reputation.
TCP port monitoring is just one component of Pulse Stack™' comprehensive uptime monitoring platform. Monitor your entire digital infrastructure from a single dashboard:
Create public status pages to keep stakeholders informed during incidents and maintenance windows.

How does TCP port monitoring work?
TCP port monitoring establishes connections to specific ports on your servers to verify they're accepting traffic. Our system attempts connections at regular intervals and measures response times to detect availability issues or performance degradation.
Which TCP ports should I monitor?
Monitor any ports that serve critical applications or services. Common choices include web server ports (80, 443), email server ports (25, 110, 143, 993, 995), database ports (3306, 5432, 1521), and any custom application ports your services depend on.
What's the difference between TCP and ICMP monitoring?
TCP monitoring verifies that specific services are responding on designated ports, while ICMP monitoring only confirms that a device is reachable on the network. TCP monitoring provides more detailed insight into application-level availability.
