Continuous External Infrastructure Monitoring

Security and IT teams need ongoing visibility into what's exposed to the internet. PortMon helps you maintain a living map of externally exposed services and catch surprises early.

Register and monitor IPs

Add your internet-facing IPs, configure alert policies, run baseline scans, and receive alerts when something changes. Remediate and re-scan to verify fixes.

  • Living inventory of external assets
  • Catch configuration drift automatically
  • Close ports before they become problems

Catch unexpected exposure

New services spun up without security review? Ports opened by mistake? PortMon alerts you when new exposure appears so you can respond before attackers find it.

  • Alerts on newly opened ports
  • Detect unauthorized services
  • Stay ahead of attackers

Vulnerability & Patch Prioritization

Not all vulnerabilities are equal. PortMon helps you focus limited patching resources on externally exposed, higher-risk services first.

Prioritize by exposure and severity

Review your scan results to identify exposed services and versions, correlate with known vulnerabilities (where available), and prioritize patching based on what's actually reachable from the internet.

  • Severity classification (Critical/High/Medium/Low)
  • Focus on externally visible issues
  • Data-driven patch prioritization

Track remediation progress

See which issues have been fixed, which are recurring, and whether your attack surface is shrinking or growing over time.

  • Historical trend charts
  • Track improvement over time
  • Identify recurring problems

Compliance & Audit Support

Auditors, insurers, and compliance frameworks want to see evidence of external perimeter monitoring. PortMon turns your continuous monitoring into audit-ready documentation.

Generate compliance evidence

Generate scan reports, show historical findings and remediation timelines, document alert policies and role assignments, and provide trend charts as evidence.

  • Export-ready scan reports
  • Historical findings and remediation timeline
  • Evidence for compliance frameworks

Satisfy cyber insurance requirements

Insurance carriers increasingly ask about external monitoring. Show them continuous monitoring instead of one-off point-in-time scans.

  • Demonstrate ongoing oversight
  • Stronger compliance story
  • Evidence for insurance renewals

Incident Response & Triage

When an incident occurs, IR teams need to quickly understand what's exposed and what changed. PortMon helps responders compare current external exposure to a known baseline.

Incident-time exposure review

During an incident, compare your latest results to the last baseline to identify new or unauthorized services or ports that may be related to the incident.

  • Compare to baseline
  • Identify what changed

Third-party infrastructure checks

Review vendor-owned internet exposure (where appropriate) to compare against internal security expectations. Feed findings into risk assessments.

  • Objective external evidence
  • Vendor infrastructure visibility
  • Feed into RiskCheck assessments
