New Free Tool Reveals Who's Tracking Your Business Online

Krebs on Security · 14 Aug 2026
Key Takeaway Use tools like DecryptAds to check which advertising and tracking companies have access to your website's visitor data, and remove any you don't recognise or need.

Every website you visit and every app you use is likely feeding data to multiple advertising and analytics companies behind the scenes. Until now, figuring out exactly who is collecting this information has been difficult, as much of it stays locked away within large advertising platforms.

A new free service called DecryptAds changes that by scraping and correlating publicly available adtech data, making it far easier to see which companies are tracking visitors on a given site or app. For small businesses, this kind of transparency can be valuable both for understanding your own website's ad and tracking setup, and for evaluating the privacy practices of vendors, partners, or competitors.

As data privacy regulations tighten and customers grow more concerned about how their information is used, tools like DecryptAds give business owners a practical way to audit their digital footprint. Knowing which third parties have access to your site's visitor data is an important step in managing both privacy compliance and reputational risk.
