AI Governance for the Enterprise — Visibility, Control and Assurance Over Every AI Interaction

AI adoption inside your organisation is already happening — usually faster than governance can keep up with it. Staff and developers are reaching for large language models through personal accounts, scattered API keys and unmanaged tools, and most organisations cannot answer the questions that matter: who is using AI, against which models, with what data, and at what cost?

D2 Technology closes that gap. We design, deploy and manage Aperture by Tailscale — a centralised AI gateway that sits between your people, your agents and every model provider, so that every request is identified, attributed, logged and governed before it ever leaves your network.

Governance Controls Built Into Every AI Request

Aperture operates as a reverse proxy for AI traffic: every request passes through it before reaching a provider, and every response passes back through it. That single control point is what makes genuine governance — rather than policy on paper — possible.

Identity-Based Access

Access is granted from your network identity layer rather than shared secrets. Every user, device and agent is identified before a request reaches a model — with no separate logins and no distributed API keys to leak.

Centralised Credential Management

Provider API keys stay in the gateway configuration and never land on developer laptops, CI runners or agent sandboxes. Rotation happens once, centrally, instead of across dozens of devices and pipelines.

Complete Audit Trails

Every AI interaction is logged and attributed to an identity — who called which model, when, through which provider, and how many tokens were consumed. Audit-ready from day one, with export to your SIEM.

Guardrails and Data Protection

Requests are inspected, modified or blocked at the gateway before they leave your network — scrubbing personally identifiable information from prompts, restricting tool declarations and enforcing content policy.

Cost and Usage Control

Token and request limits per user, team, agent or organisation, with spend caps that stop runaway costs on high-end models and reporting that shows where AI is genuinely creating value.

Governed Agent and MCP Access

Connectors proxy access to external MCP servers and HTTP APIs through a single governed endpoint, with authentication injected centrally so agents never hold credentials of their own.

See How Aperture Works

A short introduction to Aperture by Tailscale — the AI gateway behind the governance model D2 Technology implements for our clients.

Compliance-Ready AI, Without Slowing Your Teams Down

Whether you operate under ISO 27001, the Essential Eight, the Privacy Act, or sector-specific obligations, AI introduces a new class of evidence your auditors will ask for: who accessed what, using which model, and under which policy.

Aperture produces that evidence as a by-product of normal use. Policy is defined once and applied consistently across development, staging and production. Where data sensitivity demands it, zero data retention can be enabled so prompt and response content is never written to disk, while logs and events still export to your SIEM for durable, auditable records.

The outcome is governance that satisfies your risk, security and compliance teams without pushing your developers back into slow manual approval cycles — or into the unmanaged tools that created the problem in the first place.

Powered by Aperture by Tailscale

D2 Technology implements Aperture by Tailscale as the foundation of our AI governance practice.

Aperture is deployed into your own Tailscale network, so the gateway is reachable by your people, your CI/CD pipelines and your agent sandboxes without exposing anything to the public internet. It routes by model name across OpenAI, Anthropic, Google Gemini and OpenAI-compatible or self-hosted models, so adoption is typically a base URL change in the tools your teams already use — and you keep the freedom to change providers as the landscape shifts.

It also directly addresses the “lethal trifecta” risk in agentic AI — access to private data, exposure to untrusted content, and the ability to communicate externally — by separating an agent’s access to the model, to data connectors and to external connectivity, and enforcing those decisions at the gateway rather than inside the agent itself.
