Crystal Eye Declarative
Authorisation Service (DAS)

Protect API workloads across hybrid cloud and AI environments

Implement Zero Trust with
Crystal Eye Declarative Authorisation Service (DAS) 

One Platform, No Sprawl. Get started here.

Declarative Authorisation Service (DAS) is a zero-trust access control system that lets you define security policies once and enforce them everywhere across workloads, APIs, cloud, and on-prem environments. Instead of relying on firewalls or IP rules, Crystal Eye DAS uses identity, context, and policy-as-code to decide who or what can access specific resources in real time.

Why Declarative Authorisation Service (DAS) Matters

Gartner points out three realities:

  •  Zero trust requires fine-grained zoning to stop lateral movement.
  •  You need real-time visibility of east-west traffic.
  •  Edge firewalls can’t enforce processes or workloads.


Crystal Eye DAS addresses all three. It delivers microsegmentation, policy-as-code, and real-time enforcement across cloud, hybrid, and containerised environments.

Define clear “allow-on-need” policies once.
Enforce everywhere. See every decision in real time.

Built for AI and Modern Workloads

AI model control planes are a new attack surface. Crystal Eye Declarative Authorisation Service secures them without slowing delivery:

  •  Gate sensitive actions like deploy, retire, or rollback with approvals.
  •  Record every action: who, what, when, where.
  •  Block privileged containers and enforce least-privilege mounts.
  •  Apply egress allow-lists to stop shadow SaaS or data exfiltration.
  •  Enforce governance rules tied to model classification, lineage, and residency.
  •  Maintain a living inventory of signed approved images.
  •  Kill miner patterns, throttle risky API calls, and enforce budgets.


All of it runs in the same DAS policy plane your team already knows.

How Crystal Eye Declarative Authorisation Service Works

Discover
applications, workloads, and flows with live maps.

Define
rules based on identity, labels, and context; not IPs.

Enforce
policies that follow workloads as they move or scale.

Observe
with dashboards for latency, errors, and violations.

Improve
policies using real-time feedback and recommendations.

This model lines up with Gartner’s guidance to use identity and context, automate policy identification, and centrally manage across hybrid environments.
