Early threat detection<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">AI systems can analyze network traffic, access logs, user behavior, and asset changes to identify <\/span><b>indicators of compromise<\/b><span style=\"font-weight: 400;\"> (IoC) before an attack materializes.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Examples:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Unusual behavior of a device indicating possible ransomware<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">An access to systems outside of a user's normal working hours<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A peak of activity in unauthorized ports<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">This allows action to be taken <\/span><b>before the damage becomes real<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<h3><b>2. Automated and immediate response<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">AI not only detects, it can also act.

Contextual analysis and false positive reduction<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">One of the great challenges of cybersecurity is the number of false <\/span><b>number of false alerts<\/b><span style=\"font-weight: 400;\">.
