Pasadena Now | May 22, 2026
Local business publication Pasadena Now this week covered RealDefense's newly granted U.S. patent for blocking online trackers beneath the browser, spotlighting the kernel-level technical approach, its timing relative to Chrome's Manifest V3 restrictions on privacy extensions, and what the patent means for RealDefense's partner ecosystem.
The article details how the method (U.S. Patent No. 12,609,908, "Selectively Blocking Connection Requests to Ensure Privacy") cross-references incoming network traffic against a database of known tracking entities and blocks the connection at the operating system level, so web pages still load normally while silent data transmission to trackers is denied. Coverage also notes that the technology extends beyond browsers to any application that connects to the network, and that it can gate tracker access to the microphone, camera, and physical location. CEO Gary Guseinov is quoted on why a kernel-level approach delivers privacy protection that a browser update cannot disable.
