Companies Affected by CrowdStrike

The summer of 2024 saw the globe witness an event that was among the more perturbing IT outages of recent times. It was not an attack on cyberspace. It was not ransomware. The issue was caused by a software update that went wrong, and it affected the digital foundations of hundreds of businesses around the world.

This article will take an in-depth look at the businesses that were affected through CrowdStrike, the reasons it occurred, and how you can safeguard your company from similar events. We’ll also discuss the major industries affected and the financial damage that was incurred, as well as measures businesses can take in order to ensure resilience and continuity.

What Was the CrowdStrike Outage: What Happened?

The issue began on the 19th of July, 2024, after cybersecurity company CrowdStrike released a faulty update for its Falcon agent, popular software for protecting endpoints extensively utilised in Fortune 500 companies. The patch was in error and caused Windows computers to fail, which sent critical IT systems offline worldwide.

It was not an actual cyberattack; however, it was a human error that wasn’t malicious. The impact was huge. Over 8.5 million devices were affected.

According to Michael Sentonas, the president of CrowdStrike, who acknowledged during an interview on Sky News, it was “a mistake,” and the company is now focusing on the remediation process as well as compensation.
