Tracker report
Trackers on cisecurity.org
cisecurity.org loads 2 known trackers from 2 companies across 4 third-party hosts, and sets 0 cookies before you interact with anything.
What this means
When you open cisecurity.org, your browser makes 4 requests to hosts other than cisecurity.org itself. 2 of those are recognised tracking or advertising services, which means they received a record of your visit before you interacted with anything on the page. That is close to the average of 1.9 across the 11,596 sites we crawled.
Which companies receive data
Individual tracker domains matter less than who is behind them, because one company operating several services can join those observations into a single profile. On cisecurity.org, data reaches 2 distinct companies: Optimizely, Usercentrics.
How this was measured
We requested the homepage of cisecurity.org the way an ordinary browser would, read the HTML the server returned, and matched every third-party host against our public tracker signature database. Nothing was logged in, no forms were submitted, and no page beyond the homepage was fetched.
The count is a floor rather than a total. This method reads the HTML as delivered and does not execute JavaScript, so trackers injected at runtime by a tag manager are represented by the tag manager rather than counted individually. A tool claiming a complete figure is either running a full browser for every site or overstating what it knows.
Blocking these
Every request listed above can be cancelled before it is sent. That is what a tracker blocker does, and unlike hiding elements after the fact it means the tracking company never learns you were here at all.
