Darktrace

Darktrace is a wildly disruptive, fiercely modern, and rapidly accelerating British cybersecurity titan that completely revolutionized the IDPS market by abandoning signatures entirely in favor of "Unsupervised Machine Learning." While legacy IPS systems rely on a database of 'known bad' attacks, Darktrace uses AI to learn exactly what 'normal' looks like inside a specific corporation, attacking anything that deviates. The absolute core superpower of Darktrace is its "Enterprise Immune System." When installed, it watches the network for two weeks. It learns that 'John usually logs in at 9 AM and downloads 5 PDFs.' If, at 3:00 AM, John's laptop suddenly starts aggressively encrypting 5,000 files on the corporate server, Darktrace instantly recognizes this as a bizarre deviation from John's normal pattern and uses 'Antigena' to autonomously sever his connection in milliseconds. Because it requires almost zero configuration, zero signature updates, and fights zero-day ransomware entirely autonomously, it is massively popular across mid-market enterprises, high-tech firms, and organizations terrified of highly novel, never-before-seen ransomware strains.
