External exposure monitoring, without enterprise overhead.
PortMon is an external exposure monitoring platform that continuously scans public infrastructure to identify open ports, service changes, and unexpected attack surface.
PortMon is developed by Ember Labs, the product and engineering arm of Ember Trail. Ember Trail is the primary client-facing cybersecurity firm behind the Ember Trail Collective, focused on helping small and mid-sized organizations manage real-world security risk with clarity and confidence.
PortMon helps teams maintain visibility into their external footprint, detect changes early, and respond quickly to infrastructure exposure without requiring complex or enterprise-grade security tooling.
What you can do with PortMon
Continuous visibility into what is exposed, what changed, and what needs attention.
External footprint visibility
Track what is exposed to the public internet across your domains and infrastructure.
Open ports and services
Identify open ports and understand which services appear to be running.
Change detection
Detect service and exposure changes so you can respond quickly to drift and surprises.
Early alerts
Get notified when something changes, instead of finding out during an incident.
Actionable reporting
Produce clear outputs that support remediation, reviews, and audit conversations.
Right-sized security
Designed for teams that need clarity and coverage without enterprise-only complexity.
Why we built PortMon
Many organizations need to monitor external exposure and respond to changes long before they have the resources for enterprise vulnerability management platforms.
PortMon was built to bridge this gap. It provides right-sized external visibility that aligns with real operational constraints, helping teams spot unexpected exposure and prioritize fixes with confidence.
Rather than forcing small and mid-sized teams into oversized tooling, PortMon focuses on clarity, sensible defaults, and practical outcomes.
Ember Trail

Ember Labs is the product and engineering arm of Ember Trail. It designs and builds focused security tools that support Ember Trail’s security philosophy and client needs.
PortMon is developed by Ember Labs and is part of the Ember Trail Collective. Each product in the Collective is independently usable and designed to work together when broader visibility or deeper coverage is required, without forcing an all-or-nothing platform.
Security tools should support real decisions
Security decisions should be understandable. Outputs should be actionable. Tools should support real conversations rather than abstract scoring exercises.
Ember Labs products emphasize clarity, sensible defaults, and practical outcomes informed by real-world security work and regulatory expectations.
