I work as a consultant doing web development (user interfaces, APIs, cloud stuff, test automation, mobile development...). My employer is an agency providing consultants for our clients.
Our company started using Crowdstrike a few months ago and there was a lot of pushback from us employees. The primary concerns from us employees were privacy and performance. Unfortunately every service like this that I have ever reluctantly had to install has turned out to be a nightmare that causes more issues than it solves.
The premise behind adopting it is sound: security compliance with clients. As a company, we need to be able to show that we are doing everything to make sure sensitive client data is not leaked out.
As consultants we can choose which laptop we use. Most of us use Macbook Pros, where the problem doesn't occur. But there are some who prefer Windows and they have basically not been able to work today.
Some of our people have complained that even on Mac, Crowdstrike has started hogging a lot of CPU cycles for no good reason.
Crowdstrike released a guide to delete some files on Windows to get it working again, but to delete them you need to get to safe mode, which means you need to have a Bitlocker key to do that, which you most likely don't have since it's centrally managed, so you end up in this great loop of not having access to fix the issue yourself. Some of these machines are also stuck in a boot loop so they cannot get an automated update that fixes this. This is a total nightmare for IT support at companies when employees need to bring their systems in and each has to be manually updated.
I would not be surprised if this is bad enough to make Crowdstrike go under. I have no sympathy for a security company that seemingly does not understand what update rollouts are. The way these work, is that a new update to a software gets rolled out first week to say 10% of users, the next week to 20%, and increasingly more until everyone has the update. This would have avoided exactly this problem where a huge number of clients are affected, instead it would have been caught with the first 10%.
