Microsoft, a tech giant valued at $3 trillion, has faced criticism from former White House cyber policy director Andrew Grotto over serious security lapses. Grotto blames Microsoft for the 2019 SolarWinds hack and recent breaches of Microsoft Exchange Online systems and its own systems. He also highlights Microsoft’s practice of selling network logging services as an add-on instead of enabling them as standard, as well as its insertion of ads into the Windows 11 Start menu. Grotto warns that these security lapses pose a threat to national security and businesses of all sizes. Companies should double-check their cybersecurity measures, keep software updated, and train staff on avoiding hacks.
