US companies are investing unprecedented amounts in executive security as threats against corporate leaders surge. High-profile attacks, including recent killings in Manhattan and Minnesota, have prompted firms to double security measures, especially in major cities like New York. Experts attribute the rise in threats to the amplification of grievances on social media and the increasing sophistication of attacks enabled by artificial intelligence. Data shows that spending on executive protection has reached record levels, with more top officers and chief executives receiving security services than ever before, a trend expected to continue as companies respond to ongoing risks.
