Tag Firewall

TagFirewall can whitelist or blacklist tags.

TagFirewall is a paid extension that can be installed with Commanders Act TMS or run in standalone mode. Please contact a Commanders Act consultant or account manager to activate it.

Overview

TagFirewall blocks unauthorized tags (domains) in real time. This can e.g. help to block and reduce the risk of piggybacking tags. TagFirewall is highly dynamic and can therefore enrich an existing Content Security Policy (CSP) setup to resolve critical issues with tags in minutes or replace the need for a Content Security Policy (CSP) entirely. TagFirewall offers two modes:

Blacklist Mode

This mode blocks tag communication with a configurable list of domains. Communication with all other domains is still permitted.

Whitelist Mode

This mode blocks tag communication with all domains except a configured whitelist.

Setup

TagFirewall can be set up and configured with the tag template "Commanders Act - TagFirewall" in Commanders Act TMS tag library.
