"Never trust, always verify." How Zero Trust replaces the old castle-and-moat model.

Never trust, always verify.
Zero Trust inverts an old assumption: that everything inside your own network is trustworthy. Instead, every request is verified on its own — whether it comes from the office, the home office or a foreign network.
Identity, device posture and authorisation decide on access, not the location in the network. Access is granted as narrowly as possible (least privilege).
Why the castle model no longer holds.
The classic "castle and moat" model protects a hard perimeter and trusts everything inside. With cloud services, mobile devices and external partners, that clear edge no longer exists — once you're in, you can otherwise get anywhere.
We implement Zero Trust principles in architecture and operations: strong authentication, segmented access, end-to-end logging. That fits the requirements of our ISO 27001 certification.
Not a product, but a stance.
You don't buy Zero Trust as a box. It's a principle that runs across many building blocks and is introduced step by step. Applied to excess it creates friction; sensibly dosed it protects exactly where it counts.
The entry point pays off most strongly at identity and critical access — not everywhere at once.
