Your estate stays where it is. We speak to it.

A platform that requires migration before it delivers value never gets evaluated. This is everything System9 serves and everything it consumes, with the direction stated on every row.

Govern in place is a shorter sale than migrate first

Sovereign-capable is not the same as isolationist. The platform is designed to run with nothing, and to be a good citizen of everything you already own: federate your identity provider, resolve secrets from your vault, wrap your key manager, catalog your warehouse without moving it, feed your detection stack, and expose the whole thing to your assistants over an open agent protocol.

Every row below is a surface that exists. None of them is a certification, a validation or a partnership, and we do not describe them as one.

Breadth at a glance, with the direction on it

Every figure below is measured and quoted the same way across the site, a served surface is one we expose, a consumed surface is one we connect to. The rows that follow this matrix name each interface individually.

106 stream connectors: Quote the connector catalog as a catalog. An open finding records connectors that report running with no transport; verify any individual connector before demoing it.

34 data-structure types over the Redis protocol: Thirty-three are customer-visible; one (`__memttl__`) is internal bookkeeping. Pair the 34 with the 33-customer-visible note wherever the reachable surface is what is meant.

3 certificate systems at operational parity: Say "operational parity", never "feature parity".

5 PKI protocol servers: ACME, EST and SCEP are deliberately excluded. They are fail-closed scaffolds and serve in no configuration.

Data and query

Your analysts keep their tools. A credential resolves to a real directory entity with real grants, and the data-security plane is on the wire path, not beside it.

Data and query, interfaces, direction and qualifiers
InterfaceDirectionNotes
PostgreSQL wire protocolServerpsql, DBeaver, any Postgres client. Credential auth resolving to a directory entity, workspace scoping, data-security guards.
Arrow Flight SQLServerHigh-throughput columnar pulls over gRPC/Arrow, proven against a stock Arrow Flight SQL client. One endpoint per live cell for multi-cell fan-out; the data-security plane masks columns on the served stream. Bring a standard client, no BI tool is certified.
RESP2 / RESP3 (Redis protocol)ServerA native TCP server over the structure engine. Deny-by-default until the connection authenticates.
SQLServerAcross transactional and analytical engines, with cross-database federation.
GremlinServerGraph traversal.
GQL / CypherServerProperty-graph query with distributed traversal and algorithms.
GraphQLServerMerged domain schema with subscriptions and query cost analysis.
KQLServerTokenizer, parser, function registry and translator.
PromQLServerParser and engine including rate, increase and histogram quantiles.
Streaming SQL and complex event processingServerWindows, watermarks, temporal joins, pattern matching, emit semantics.
Iceberg REST catalogServerTable registration and metadata publishing for external readers.
Delta Sharing protocolBothOpen cross-organization sharing, as server and as client.
OpenMetadata-compatible RESTServerTables, topics, databases, tags, glossary terms, lineage to depth five, full-text search.

Storage and files

All behind one shared namespace guard, deny-by-default. Operations we do not enforce are refused rather than accepted and ignored.

Storage and files, interfaces, direction and qualifiers
InterfaceDirectionNotes
S3 (SigV4)ServerObject and multipart surface, tagging with namespace-scoped search, keyset pagination for stable iteration over changing datasets.

Object change streamsServerA native subscription delivering write events.

Messaging and events

A message carries the same classification, workspace scope and audit trail as a table.

Messaging and events, interfaces, direction and qualifiers
InterfaceDirectionNotes
Native publish/subscribe (HTTP and gRPC)ServerSubjects, consumer groups, durable cursors, transactions with producer fencing.
MQTT 5.0ServerA bridge with a documented mapping: topic to subject, quality-of-service to delivery semantics, retained to retention policy, will to scheduled delivery.
AMQPServerBridge.

Cloud messaging (major providers)ClientQueue, topic, stream and event-bus services, with producers created behind an egress guard.
PGP message transportBothEnd-to-end encrypted envelopes with recipient and sender selection policy.
Disruption-tolerant bundles and offline transferBothFor contested and absent links, with custody transfer and contact-graph routing.

Identity, security and PKI

Federate with what you already run. Your joiner-mover-leaver process stays; agents and devices land in the same directory as the federated humans.

Identity, security and PKI, interfaces, direction and qualifiers
