Crowdstrike is certainly not required for a device to be considered secure, it is a tool that uses AI and ML to detect and prevent malware, 0-day exploits and other cyber threats in real-time across endpoints.
No it does not. Such thing does not exist.
Most antivirus programs rely primarily on signature-based detection and heuristic analysis rather than advanced machine learning algorithms. While some modern antivirus solutions incorporate basic machine learning for anomaly detection, they do not typically employ the sophisticated, self-learning AI systems that are characteristic of true artificial intelligence applications. And I do understand Crowdstrike is more than just an antivirus.
Please don't repeat CNBC Stock market pumping memes. No they are not an "AI Stock"
It's not security pixie dust, and might introduce more security vulnerabilities itself, but it's probably pretty good at preventing Alice from accounting from running a random macro-enabled excel file with a malicious payload.
