On Friday, a global outage occurred in Microsoft's system, which was caused by a software update from global cybersecurity company CrowdStrike. Microsoft estimates that CrowdStrike's update affected 8.5 million Windows devices, accounting for less than 1% of all Windows devices.
Information security experts point out that Friday's large-scale technical failure is another example of the world's extreme dependence on a few technology companies.
"I think the biggest problem here is how the world has become so dependent on so few companies," said Alex Hamerstone, director of solutions consulting at cybersecurity company TrustedSec. "A problem with one company could have widespread impacts across all different verticals globally."
