Originally developed by Vern Paxson in the 1990s under the name “Bro,” Zeek was designed to provide deep insights into network activity across university and national lab networks. In 2018, the project was renamed Zeek to reflect its growing role and evolution in the world of network security. Today, Zeek remains a highly sought after open source solution thanks to the </span><span style="font-size: large;">development and financial support of Corelight.</span></p> <p style="text-align: center;"><span style="font-size: large;"><br />Unlike traditional security tools such as firewalls or intrusion prevention systems, Zeek is not an active defense mechanism. Instead, it operates quietly on a sensor鈥攚hether hardware, software, virtual, or cloud-based鈥攁nalyzing network traffic in real-time. Zeek captures high-fidelity transaction logs, file contents, and customizable data outputs, which are ideal for manual review or integration into SIEM systems for security analysts.<br /></span></p></div> </div>  </div>  </div>  </div> <div class="et_pb_section et_pb_section_2 et_pb_section_parallax_hover et_pb_with_background et_section_regular" > <div class="et_pb_row et_pb_row_2"> <div class="et_pb_column et_pb_column_4_4 et_pb_column_2 et_pb_css_mix_blend_mode_passthrough et-last-child"> <div class="et_pb_module et_pb_text et_pb_text_4 et_pb_text_align_left et_pb_bg_layout_light"> <div class="et_pb_text_inner"><span style="color: #00ccff;"><span style="font-size: 26;">BY THE NUMBERS</span></span></p> <p><span style="color: #ffffff;"><span style="font-size: xxx-large;">70+ </span><span style="font-size: 26px;">log files provided by default<br /></span></span><br /><span style="color: #ffffff;"><span style="font-size: xxx-large;"> 3,000+ </span><span style="font-size: 26px;">network events tracked<br /></span></span><br /><span style="color: #ffffff;"><span style="font-size: xxx-large;">10,000+ </span><span style="font-size: 26px;">deployments worldwide<br /></span></span><br /><span style="color: #ffffff;"><span style="font-size: xxx-large;">6,400+ </span><span style="font-size: 26px;">GitHub stars<br /></span></span><br /><span style="color: #ffffff;"><span style="font-size: xxx-large;">20+ </span><span style="font-size: 26px;">years of federally-funded R&D<br /></span></span><br /><span style="color: #ffffff;"><span style="font-size: xxx-large;">260+ </span><span style="font-size: 26px;">community-contributed packages</span></span></p></div> </div>  </div>  </div>  </div> <div class="et_pb_section et_pb_section_3 et_pb_fullwidth_section et_section_regular" > </div> <div class="et_pb_section et_pb_section_4 footer-pp et_pb_with_background et_section_regular" > <div class="et_pb_row et_pb_row_3"> <div class="et_pb_column et_pb_column_4_4 et_pb_column_3 et_pb_css_mix_blend_mode_passthrough et-last-child"> <div class="et_pb_module et_pb_text et_pb_text_5 et_pb_text_align_center et_pb_bg_layout_dark"> <div class="et_pb_text_inner"><p style="text-align: left;"><span style="font-size: 26px; font-weight: bold; color: #294488;">Join the Zeek Community!</span><span style="font-size: large;"></span></p> <p style="text-align: left;"><span style="font-size: large; color: #666666;">Contribute to Zeek by sharing documentation, code, feature ideas, or spreading the word.
