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, rather than one of each per framework. Policy is enforced today on the root agent it provisions.
The outcome
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.
One deterministic policy engine and one audit-of-record instead of one of each per framework. Rules are authored once, evaluated on every request against the agent SYNTHERA provisions, 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.
How 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.
Policy
A deterministic, sandboxed evaluation engine – repeatable, fast, with an enforced instruction budget. Rules are authored off the hot path and evaluated on it against one shared logic. A verdict that blocks is live: the deployed substrate loads its rules at boot, evaluates every request against them, and a refusal names the rule that produced it. The default verdict for a request no rule matches remains allow.
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.
Audit
A tamper-evident event log. Every action is recorded to one audit-of-record that no party can quietly rewrite after the fact.
Federation
Coordination over a single, well-defined surface, so systems coordinate through SYNTHERA rather than bespoke glue. In progress: the router is in-process today – it reports its own readiness as Degraded – and cross-process transport between independent systems is not shipped.
What a customer gets beyond the open standard
Anyone can adopt VAID, and anyone holding the signer's public key can verify its signed actions without lock-in – that's the point of an open standard. SYNTHERA is the infrastructure to operate it at scale, and it's the commercial product. It is in development, not generally available; the three below describe the intended offering, not what you can buy today.
Hosted authority
The issuing and revoking authority for VAIDs, operated for you – so identities can be minted, delegated and cut off centrally. It is our name for the aggregate of KMS-backed keys, durable audit and durable revocation, not a single component that exists today.
Enforcement mesh
Policy decisions applied at call time on the hot path, without each service wiring its own enforcement. Applying this across a whole estate needs the cross-process transport that is not yet shipped.
Audit-of-record
A durable, hash-chained history of what every agent did, and under whose authority. The ledger itself is real and its tamper-evidence is proven by attack rather than asserted: mutate a written row directly in the database and recomputation catches it, names the sequence number and exits non-zero. The audit seam is open source in vaid. What is commercial — and what we do not operate for anyone today — is retention: the ledger kept, run and exported on your behalf.
Proof
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, rather than one of each per framework below.
Keep the frameworks and clouds you already run. SYNTHERA sits above them – today it enforces policy on the root agent it provisions.
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.
