Darktrace Immune System, the world's most trusted autonomous cyber defense platform, is it. Cyber AI, the award-winning Cyber AI, protects your workforce from sophisticated attackers by detecting, investigating, and responding to cyber-threats wherever they occur. Darktrace Immune System, a market-leading cybersecurity technology platform, uses AI to detect sophisticated cyber threats, including insider threat, criminal espionage and ransomware. Darktrace is analogous to the human immune systems. It learns the organization's 'digital DNA' and adapts to changing environments. Self-learning, self healing security is now possible. Ransomware and other machine-speed attacks are too fast for humans to handle. Autonomous Response relieves security personnel of the burden by responding 24/7 to fast-moving threats. AI that responds.
