For MSPs & MSSPs
External visibility for every client, without the overhead
MSPs and MSSPs need a lightweight way to monitor client external exposure. PortMon delivers continuous port and service monitoring across all your clients—without agents, complex deployment, or enterprise pricing.

The challenge
MSPs face unique external visibility challenges
No visibility across clients
Most MSPs don't have a unified view of what's externally exposed across all their client environments. Each client is a blind spot.
Heavyweight tools don't scale
Traditional vulnerability scanners are expensive, complex, and hard to deploy across dozens of client environments. You need something lighter.
Manual processes don't keep up
Point-in-time scans and manual checks can't keep pace with infrastructure changes. Exposure drifts between reviews.
Industry-specific problems
Security challenges specific to managed service providers
Multi-client infrastructure sprawl
MSPs and MSSPs manage dozens or hundreds of client environments. Each one has its own external footprint, and keeping track of what's exposed across all of them is a constant challenge.
Client security expectations
Clients increasingly expect their MSP to provide visibility into their security posture. Without a lightweight external view, you're left scrambling to answer basic questions about exposure.
Compliance and audit support
Many clients face regulatory requirements that demand evidence of continuous monitoring. You need a way to show ongoing external oversight without heavyweight tooling.
Cyber insurance questionnaires
When clients renew their cyber insurance, carriers ask about external monitoring and vulnerability management. A documented process makes renewals smoother for everyone.
