Snort is an open-source intrusion prevention system (IPS) capable of real-time traffic analysis and packet logging. Snort 3 is the next step in our years-long journey of protecting users networks from unwanted traffic, malicious software and spam and phishing documents. Rules are faster and more efficient, users have more control over their Snort experience, and it runs on multiple environments and operating systems. The latest version of Snort, 3.1.0.0, is the result of more than seven years of development and hard work from our team.”]
