XDR
XDR (Extended Detection and Response) is a modern security system that helps protect organizations from cyber threats. Think of it as an advanced security guard system that watches over all parts of a company's computer systems - from employee laptops to cloud services. Unlike older security tools that only look at one area, XDR combines information from many sources to spot and stop threats more effectively. It's like having security cameras that not only record incidents but can also automatically respond to threats. Similar tools include EDR (Endpoint Detection and Response) and SIEM (Security Information and Event Management), but XDR is considered more comprehensive and modern.
