近年來，警方嚴打網絡有組織制造傳播謠言犯罪，破獲涉網案件逐年攀升，3年抓獲涉網嫌疑人3萬余人，打擊網絡違法犯罪創歷史同期最好水平。

2011年北京警方成立網絡安全保衛總隊，先后開展了“春風行動”、“集中打擊整治網絡違法犯罪”、“打擊網絡有組織制造傳播謠言犯罪”、“網上治安綜合治理”等專項行動，高強度打擊網絡違法犯罪。

警方提供的數據顯示，2011年破獲各類涉網案件3500余起，抓獲違法犯罪嫌疑人3600余名；2012年破獲涉網案件3800余起，抓獲違法犯罪嫌疑人4200余名；2013年破獲各類涉網案件7200余起，抓獲違法犯罪嫌疑人2.3萬余名。

在專項行動中，北京警方將頻頻策劃網絡事件、恣意制造傳播謠言、肆意踐踏公共道德的網民“秦火火”、“立二拆四”抓獲。

這些涉網案件中，最引人關注的是網絡販槍犯罪，一個設在境外的涉槍論壇網站，專為注冊會員提供氣槍、仿真槍、槍支配件、軍品等物品。警方經過偵查，掌握涉案人員740人，遍布內地29個省市自治區。在公安部統一指揮下，北京警方抓獲嫌犯40余人，收繳各類槍支90余支。

北京警方嚴厲打擊利用網絡傳播恐怖音頻、視頻犯罪，截止今年6月底，共計摸排網上涉恐線索3300余條，清理處置涉恐音視頻和電子書728部，查處涉恐人員50余人，有效遏制了暴恐音視頻在網上的傳播。

自2011年以來，北京警方全面清理網上有害信息，截至今年6月底，已處置網上各類違法有害信息130余萬條。僅今年6月中旬至9月中旬，網絡110違法犯罪線索舉報平臺，共接網民舉報9500余條，日均90條，比去年同期下降16.1%。網民普遍認為，網上秩序好轉、安全感顯著提升。
