Every device, server, or cloud workload that connects to the internet has a set of network doorways known as ports. When those doorways are left open unnecessarily, or when the services behind them are misconfigured, attackers gain easy entry points. Sensagraph's Network Exposure & Open Port Detection capability automatically maps your external attack surface, showing you exactly what the outside world can see about your infrastructure.
Sensagraph performs deep reconnaissance against your public IP addresses and domains, enumerating every reachable port, identifying the service and version listening behind it, and assessing whether that exposure is justified. The result is a clear, prioritised view of where your network is over-exposed — and what to do about it.
Map your true attack surface in minutes
Most organisations underestimate how much of their network is reachable from the public internet. Forgotten admin panels, legacy services, and development ports often remain open long after they should have been closed. Sensagraph reveals all of them.
Comprehensive Port Discovery
Sensagraph scans the full range of TCP and UDP ports, not just the common ones, so nothing slips through the cracks.
- Full 65,535 port coverage on demand
- Fast discovery of the most exploited ports
- Detection of non-standard or hidden services
Accurate Service & Version Identification
For every open port, Sensagraph identifies the exact service and version running, enabling targeted risk assessment.
- Protocol-level fingerprinting
- Software version detection
- Correlation with known vulnerabilities
Operating System Fingerprinting
Sensagraph determines the underlying operating system of exposed hosts so you understand the full context of each finding.
- Identifies outdated or end-of-life systems
- Highlights platforms with known weaknesses
- Provides context for prioritising fixes
Detection of Unnecessary Exposure
Sensagraph flags services that should never be public-facing, such as databases, admin panels, and remote management ports.
- Database ports exposed to the internet
- Remote desktop and SSH on default ports
- Internal management interfaces accidentally public
Misconfiguration Insights
Beyond simply listing open ports, Sensagraph evaluates whether each exposed service is configured securely.
- Default banners and credentials checks
- Insecure protocol versions
- Unhardened service configurations
From discovery to actionable insight
Finding open ports is only half the job. Sensagraph turns raw scan data into prioritised, business-friendly reports that help you reduce risk quickly.
