Zero Trust for vendors? So, if my coffee machine calls their API to order beans, I need multi-factor authentication for *that* too? Guess I’ll stick to tea. Seriously though, supply chain vulnerabilities are a scary thought!
That’s a great point! The idea of every device needing MFA does sound a bit extreme. However, it does highlight the core principle of Zero Trust, which extends to any device interacting with our systems, even our beloved coffee machines! Supply chain vulnerabilities are a growing concern that we all need to address, in a measured way.
