Industry blocklist

Telecommunications blocklist

Give voice and network teams one current source list for the exposed services they manage across separate systems.

The coverage

What our sensors observed

Our sensors saw probes against voice systems, carrier management, routing, and subscriber services. The coverage spans call handling as well as the network interfaces used to run those services.

Why use this feed

Voice and network teams often work across separate service logs. Apply the feed at gateways and management edges so observed scanner sources can be handled through one regularly updated rule.

In your network

Where this feed fits

Use the observed source list where your existing edge controls meet these reachable services.

Voice gateways

Bring observed scanner sources into the perimeter rules around reachable call handling and voice administration services.

Carrier management

Use one feed across management edges where reviewing separate device logs would delay a network response.

Subscriber service edges

Review the source list alongside existing access controls before applying it to services that need outside connectivity.

Getting started

Put the feed to work

Choose your industry coverage, connect the feed to your existing firewall, and review exceptions with the people who run each service.

Choose coverage

Select this industry in a blocklist plan. Your selected industries and included threat categories are delivered in one continuously updated feed.

Connect your edge

Pull the feed in a supported format or use a firewall preset. Optional network aggregation can help where rule capacity is limited.

Review access

Check exceptions and existing allowlists before applying a deny rule to any service that needs outside connections.

Scope of the data

What this feed measures

The mapping covers voice, routing, management, and subscriber services. A probe against one of them does not prove it belongs to a carrier.

Our sensors record connections to mapped services. The resulting source list helps you review or block observed scanners; it does not reveal what those scanners intended to do.

Industry blocklists

Start blocking observed scanner sources.

Test a scanner sample in your existing security tools, then choose the coverage that fits your network.

Your next step

Choose this industry in a blocklist plan. The feed stays current as our sensors observe new scanner sources.
