DuckDuckGo DuckDuckGo (DDG) is an Internet search engine that emphasizes protecting searchers' privacy and avoiding the filter bubble of personalized search results. DuckDuckGo distinguishes itself from other search engines by not profiling its users and by deliberately showing all users the same search results for a given search term. DuckDuckGo emphasizes returning the best results, rather than the most results, and generates those results from over 400 individual sources, including key crowdsourced sites such as Wikipedia, and other search engines like Bing, Yahoo!, Yandex, and Yummly.
Windows Filtering Platform In Microsoft computer-systems, the Windows Filtering Platform (WFP) comprises a set of system services and an application programming interface first introduced with Windows Vista in 2006/2007. It allows applications to tie into the packet processing and filtering pipeline of the Next Generation TCP/IP network stack. It provides features such as integrated communication, and administrators can configure it to invoke processing logic on a per-application basis. Microsoft intended WFP for use by firewalls and by other packet-processing or connection-monitoring components, such as antivirus and antimalware software and parental controls. Additionally, WFP is used to implement NAT and to store IPSec policy configuration.
