But no one was hacked? Some computers were down for a little bit, but no breach occurred, no data was trashed or leaked, no unauthorized access was gained. This wasn't a security event. In fact, for huge numbers of systems going offline is a far better alternative than say, failing open.
Look at other security related companies of similar age and entrenchedness...
Okta was breached twice by bad auth on their ticketing system. They are an auth company. This led to other hacks. They still are doing OK, with growing revenue.
Solarwinds was breached and became the attack vector for several major hacks. They are still doing OK - in fact revenue has grown since then. (although solarwinds is much older).
Cloudflare has caused major outages - their revenue has grown too.
And on and on.
Crowdstrike has had a rough 2024. They are also still the company that was called in to consult on breach after breach for the last decade+. If they get their shit together, next month at defcon Crowdstrike people will likely be drinking for free (and being the butt of some jokes). By next year few people will even remember this, and very very few will be uspet/angry about it. A huge number of affected IT people are already looking at it as "haha those guys messed up" and not even thinking about "how do we get off crowdstrike". No software is perfect, and very little of it is even any-good - people are willing to give those who make generally decent software (and have an otherwise good reputation) a lot of slack.
I could be wrong, but I really doubt this kills the company or the brand rep.
