The foundation

SYNTHERA

SYNTHERA is the trust and coordination foundation for multi-agent systems. It operates the open VAID standard at enterprise scale – one identity, one policy engine, one audit-of-record for every agent, framework and cloud above it.

01The outcome
Before

Every team building with agents writes its own enforcement, audit and policy logic – once per framework, once per cloud. Rules drift between systems, logs don't reconcile, and nothing is verifiable end to end.

After

One deterministic policy engine and one audit-of-record cover every framework and cloud you run. Rules are authored once and enforced identically everywhere, and the record is tamper-evident.

SYNTHERA is what running the VAID standard at enterprise scale looks like – the single foundation every tenant, and every agent you build, sits on.

02How it works

SYNTHERA is infrastructure, not a library you bolt on. VAID is the open identity primitive underneath; the foundation adds the four services every agent and every system above it consumes – and never reimplements.

FOUNDATION SERVICE 01

Policy

A deterministic evaluation engine – sandboxed, repeatable, fast. Rules are authored off the hot path and enforced on it, so every system evaluates against the same logic.

deterministic · sandboxed · authored elsewhere
FOUNDATION SERVICE 02

Capabilities

Authority is granted as bounded, scoped capabilities. An agent can do exactly what its capability set allows and nothing more – least authority by construction.

scoped grants · least authority
FOUNDATION SERVICE 03

Audit

A tamper-evident event log. Every action is recorded to one audit-of-record that no party can quietly rewrite after the fact.

FOUNDATION SERVICE 04

Federation

Coordination over a single, well-defined surface. Independent systems coordinate through SYNTHERA, not through bespoke glue between each other.

What a customer gets beyond the open standard

Anyone can adopt and verify VAID without lock-in – that's the point of an open standard. SYNTHERA is the infrastructure that operates it at scale, and it's the commercial product.

Hosted authority

The issuing and revoking authority for VAIDs, operated for you – so identities can be minted, delegated and cut off centrally.

Enforcement mesh

Policy decisions applied at call time across your estate, on the hot path, without each service wiring its own enforcement.

Audit-of-record

A durable, tamper-evident history retained as the single source of truth for what every agent did, and under whose authority.

Architectural rules
R1 – The core is canonical. Systems above it subscribe and project from it. They never duplicate its state.
R2 – Enforced on the hot path, authored off it. The core evaluates; authoring happens elsewhere.
R3 – Primitives are consumed, never reimplemented. One identity model, one audit log, one policy engine.
03Proof
Live today The foundation runs live on Cloud Run, and governance has been demonstrated framework-agnostic across ADK, LangChain and OpenAI adapters – the same identity, policy and audit for all of them. Every layer speaks VAID, evaluates against the same policy, and writes to the same audit log; that shared foundation is what lets independent systems compose without custom integration.

You don't rip anything out

SYNTHERA sits above the frameworks and clouds you already run. It unifies them; it doesn't replace them.

SYNTHERA + VAID – one verifiable identity, one policy engine, one audit-of-record, across everything below.

Keep the frameworks and clouds you already run. SYNTHERA sits above them.

SYNTHERA is the trust layer for multi-agent systems: every agent gets a verifiable identity, scoped authority and a tamper-evident record, so software from different teams, vendors and frameworks can act on each other’s behalf without custom glue between every pair.
