Open Port Detection

Open Port Detection Solution

Highlight external attack surfaces and expose easy entry points – so you can strengthen defensive perimeters and improve your security posture.

Increase Visibility From Port to Port

Hackers are constantly looking for low-hanging fruit. Don’t make it easy for them to break in.

Open port detection (also referred to as external recon) monitors for potential exposures caused by open ports connected to remote desktop services, shadow IT and more—so you can identify tactical opportunities to improve your external security posture.

What is Open Port Detection?


Find Easy Targets
Find Easy Targets

By highlighting open ports from services like RDP/RDS, SMB (Windows File Sharing), SQL server databases and more, you can uncover potential entry points before attackers do.

Scan with Context
Scan with Context

Powered by Huntress and leveraging Shodan.io, each scanned IP address includes protocol and port numbers, the last time it was queried by Huntress and (when available) the service running on a particular port.


Secure Customers
Secure Customers

With scans for each of your protected environments, you can assess new and existing customers to define acceptable risk levels and introduce appropriate controls where needed.


Identify Changes
Identify Changes

With regular scans and updates, you can identify any configuration changes or unexpected activity that may otherwise go unnoticed.

Secure Your Perimeter with Continuous Open Port Monitoring

By organizing this data in a central location, Open Port Detection helps you highlight important focus areas and identify ways to reduce external attack surfaces. 

While any open port can be an attack surface, they’re sometimes required to provide necessary services to an organization. Open Port Detection provides visibility so you can ensure that ports are open in a secure and appropriate manner—a critical step in protecting your customers.
