Cybersecurity is a vital part of our modern business world, and few names carry as much weight as CrowdStrike, a leading cybersecurity firm. Known for its commitment to keeping enterprises safe from digital threats, CrowdStrike’s Falcon platform is a cornerstone for many businesses. But even the most trusted names face challenges, as we saw on July 19, 2024, during a major CrowdStrike global IT outage. This event disrupted numerous businesses across critical industries worldwide, showing that no one is immune to operational hiccups.
From finance to healthcare and even airports, the global IT outage had ripple effects across sectors that rely heavily on CrowdStrike’s infrastructure. In this blog, we’ll walk through what happened during the CrowdStrike outage, how it affected businesses and users, explore possible causes, and discuss what CrowdStrike did to respond. By learning from this, we can all be better prepared for future global tech outages.
On July 19, 2024, CrowdStrike experienced an unexpected global IT outage that took businesses and institutions by surprise. A technical failure within CrowdStrike's network caused interruptions that left millions of endpoints—particularly Windows devices—vulnerable. CrowdStrike’s Falcon platform, renowned for its cutting-edge cybersecurity solutions, faltered during this event, with as many as 8.5 million Windows devices impacted worldwide.
Among those most affected by the outage were industries that rely on real-time security monitoring, such as airports and airlines. Airport operations were heavily affected, with delays and cancellations of thousands of flights resulting from the disruption in CrowdStrike’s services. Similarly, the financial services and healthcare sectors were left vulnerable to potential cyber threats during the downtime.
The CrowdStrike CEO George Kurtz stepped forward, acknowledging the gravity of the situation and reassuring customers around the world that his team was working around the clock to resolve the issue. A fix was rolled out quickly, but the damage from the global tech outage had already touched countless Crowdstrike customers across many industries.
The CrowdStrike outage affected not only the IT systems but also the bottom line for many businesses. From financial institutions to critical infrastructure like healthcare and transportation, the lack of cybersecurity services left organizations vulnerable. Businesses dependent on CrowdStrike’s Falcon platform had to brace themselves against the possibility of being exposed to malicious threats without their usual defenses in place.
Take airports, for example. With real-time monitoring compromised, many were forced to cancel flights. Meanwhile, the financial sector—already a prime target for cyberattacks—was exposed to a greater risk of unauthorized access or breaches.
Beyond the immediate industries, Microsoft estimated that the global Windows outage affected 8.5 million Windows devices. This means companies relying on Microsoft ecosystems were also left scrambling to protect their operations. Many businesses had to implement emergency protocols to minimize their exposure to threats. The consequences were clear—without CrowdStrike’s Falcon sensor software, companies were facing potential data breaches, compliance issues, and loss of operational efficiency.
While CrowdStrike hasn’t released a full report of the preliminary post-incident review, early indications from the incident's analysis suggest a faulty software update was the culprit. The Falcon sensor software, which is central to real-time threat detection, experienced an error that led to the widespread outage. It’s a reminder that even minor software issues can have major consequences, especially in global systems protecting millions of endpoints.
Some experts also speculate that the growing complexity of modern cybersecurity environments, which integrate platforms like Microsoft Windows with multi-layered security solutions, may have played a role in exacerbating the issue. These intertwined systems mean that even small failures can cascade across vast networks.
Meanwhile, the Crowdstrike boss has said the company is actively working with customers impacted by a defect in the Falcon sensor software to restore operations fully. While no evidence points to a targeted security incident or cyberattack, this occurrence still reminds us that even the most advanced platforms, like CrowdStrike’s, can encounter unexpected challenges.
As soon as the scale of the global IT outage was clear, CrowdStrike moved quickly to deploy a solution. The company rolled out an emergency update to fix the issue, which was later identified as being linked to the Falcon sensor software. Most systems were restored within a few hours, but during that critical downtime, CrowdStrike maintained steady communication with its customers. They reassured businesses that everything was being done to get services back online.
Beyond just technical support, CrowdStrike provided businesses with resources to help them navigate the outage and minimize further disruption. Their approach underscored a deep commitment to restoring trust and ensuring that such an event wouldn’t happen again. A post-incident review was started to thoroughly understand what went wrong and to take the necessary steps to prevent another global tech outage in the future.
One key lesson from this CrowdStrike outage is that businesses must be prepared for disruptions, even when relying on industry-leading vendors. A solid incident response plan is essential for handling major service provider outages. It’s not enough to have a cybersecurity provider like CrowdStrike—you need to be ready with an internal plan to manage downtime, handle communications, and ensure operational continuity.
Having redundant systems in place can also make a big difference. Businesses with backup systems or failover mechanisms fared much better during this global IT outage. By reducing dependency on a single provider, companies were able to stay functional, even when the global tech outage affected millions of devices.
For those who didn’t have backup systems, this serves as a reminder to invest in infrastructure that can withstand a widespread outage. Regular backups, alternative services, and training key personnel on how to manage during crises can mitigate the damage during widespread IT outages.
In the aftermath of the CrowdStrike outage, the issue has sparked conversations about the future of cybersecurity. Trust in vendors like CrowdStrike is crucial, and they’ll need to demonstrate ongoing improvements in their infrastructure to maintain that trust. Cybersecurity companies will likely prioritize redundancy and communication with clients during future outages. Businesses, in turn, will need to collaborate more closely with their vendors to ensure they stay resilient in the face of disruptions.
Ongoing innovation and investment in infrastructure resilience will be critical to prevent these issues. By quickly pushing updates to its Falcon sensor post-outage, it shows that the industry is already responding to this need. Businesses must keep their systems up-to-date and ensure they’re equipped to handle global tech outages in an increasingly connected world.
The CrowdStrike global IT outage showed us just how vulnerable we can be, even when using top-tier cybersecurity providers. It’s a powerful reminder that businesses must always be prepared for the unexpected, with robust incident response plans, redundancy systems, and clear lines of communication.
The key takeaway? Preparation and resilience are critical. By ensuring you have backup systems in place and a strong response plan, your business can navigate even the most challenging outages without falling behind.
