July 18, 2024. A single faulty CrowdStrike update crashed an estimated 8.5 million Windows computers. Airlines grounded. Hospitals cancelled surgeries. Banks went dark. The economic damage ran into the billions.
Most businesses watched it happen and moved on. That reflex — “glad it wasn’t us” — is exactly the problem.
What Actually Went Wrong
It wasn’t a cyberattack. It was a software validation failure. One error in a content update, deployed globally at once, with no adequate rollback mechanism. The irony: this was supposed to be security software.
The Real Lesson for Business Owners
This wasn’t a CrowdStrike problem. It was a concentration risk problem. When your security, backup, and recovery all depend on a single vendor — and that vendor has a bad day — you go down with them.
Ask yourself:
- If your primary security tool failed right now, what would happen?
- Do you have verified, tested backups that exist independently of your primary tools?
- When was the last time you tested a full disaster recovery scenario?
What Most Businesses Still Don’t Have
- No tested recovery plan — they think their backups work because they exist
- No vendor redundancy — single points of failure across their entire stack
- No incident response plan — no written steps for “what to do when X goes down”
What NSI Tech Does
We run IT infrastructure audits to identify exactly where your business has single points of failure — and build redundancy before a vendor’s bad day becomes your worst day.
If you haven’t audited your resilience posture since 2024, you’re probably due. Talk to us.
