The phrase "Never Trust, Always Verify" has become the unofficial slogan of Zero Trust. It is memorable. But it is also incomplete.
Perhaps the better description is this:
Trust when necessary. Verify continuously. Assume every trust decision can eventually become wrong.
That is not paranoia. It is engineering.
Cybersecurity is not about eliminating trust. It is about designing systems that continue to protect the organisation when trust inevitably fails.
Because in cybersecurity, the most expensive mistake is rarely trusting someone. The most expensive mistake is assuming that trust can never be wrong.
