Zero Trust: security when the perimeter no longer exists

The old model — a wall at the perimeter, full trust inside — doesn't survive the cloud or remote work. Zero Trust starts from an uncomfortable, liberating principle: no request is trusted by default.

The three principles

• Always verify: authenticate and authorize every access, even the one coming from inside the network.
• Least privilege: grant only the access needed, for as long as needed. A permanent credential is security debt.
• Assume breach: design as if the attacker is already inside. Segment to limit the damage.

In practice

• Strong identity: mTLS between services, granular IAM for people and machines.
• Explicit, versioned policies — no implicit rules.
• Audit everything: if it wasn't logged, it didn't happen.
• Automatic secret rotation.

Not a product, a posture

Zero Trust doesn't come in a box. It's a set of architecture decisions. The good news: you can evolve incrementally, starting with the most sensitive access.

Tools that help

On Kubmix Cloud you get granular IAM, a Secrets Manager, isolated VPC and WAF — the blocks to build a Zero Trust architecture without reinventing the wheel.
