Taktikal-Scanner is an advertising supply chain scanner published under the Taktikal brand on a subdomain of fasttvltd.com, the domain of the connected TV advertising marketplace FAST TV. Its documentation states that it requests the public IAB Tech Lab transparency files ads.txt, app-ads.txt and sellers.json in order to map seller relationships for anti-fraud research, that it reads robots.txt before other requests, that it honours Crawl-delay values up to 60 seconds, and that it fetches a handful of files at most without aggressive re-crawling. The operator publishes no IP ranges, but does document forward-confirmed reverse DNS against hostnames ending in scanner.fasttvltd.com, a zone under a domain it controls; every source address seen in our own traffic forward-confirms into that zone. No third-party bot catalogue lists this agent and the operator legal name is inferred from the domain rather than stated on the page.

At a glance

Operator: FAST TV Ltd
Type: Advertising

How Centinel checks it

User agent: The request calls itself this crawler. Anyone can send the same string.
Reverse DNS: The client address resolves to a hostname the operator controls, and that hostname resolves back to the same address.

A request that passes one of these checks is Taktikal Scanner itself. One that only matches the user agent is reported as unverified. The match tokens, verification domains, and address feeds are not published here.

Allowing or blocking it

The crawler object in the /validate response sets access_allowed to true only for a verified source that your tenant allowlists. A policy rule can allow or block this crawler by its category, Advertising.
