PortMon

Know exactly what you're exposing to the internet.

PortMon continuously scans your IPs, identifies open ports and services, and flags risky exposure, so you can fix problems before attackers even see them.

External visibility
is broken for SMBs.

Traditional vulnerability scanners are heavyweight, noisy, and focused on internal assets. You need external visibility, fast.

Know what's exposed

Continuous scanning of your internet-facing IPs so you always know which ports and services are reachable from outside.

Prioritize risky exposure

Focus limited security time on externally visible services and findings that are more likely to matter.

How PortMon works

See the full workflow

A straightforward workflow for monitoring your external attack surface, from setup to continuous visibility.

Register your IPs

Add the IP addresses you want to monitor.

Scheduled scanning runs automatically

Recurring scans keep your external view current without manual triggering.

See what's exposed

Open ports, running services, and severity ratings.

Track changes

Alerts when new ports open or services change.

Port and service change alerts

Scheduled monitoring detects new ports, service changes, and exposure drift automatically so you can respond quickly without manual triggering.

Historical trends

Track exposure over time across scheduled scans so you can spot drift, verify fixes, and show progress.

PortMon

Trend: ports reduced

Fewer exposed ports over the last 30 days across scheduled scans.

Port opened: 8080/tcp

Continuous monitoring

Scheduled scans keep your external view current. Catch drift and new exposure automatically.

Threshold-based alerts

Get notified when new ports open, ports close, or services change. Stay ahead of exposure drift.

Historical trends

Track improvement or drift over time. Show auditors and insurers your continuous monitoring story.

For MSPs & MSSPs

Get client visibility without heavy tooling.

MSPs and MSSPs need a lightweight "always-on external view" for client environments. PortMon delivers continuous monitoring without agents or complex deployment.
