OPrAOn Prem AccessBook a demo
Secure by design. Deployed by you.

Your data stays in.
Access moves forward.

Give cloud apps, internal tools and AI agents governed access to on-prem databases, S3-compatible storage and internal APIs—without exposing the systems behind them.

THREE ACCESS LAYERS. ONE CONTROL PLANE.

Every request. Governed.

Apply consistent identity, policy and audit controls across data, files and internal services.

01

Database access

Expose reviewed, parameterised SQL as clean REST and OpenAPI endpoints. Callers never submit raw SQL or connect directly.

02

S3-compatible storage

Provide controlled access to on-prem object storage through familiar S3-compatible operations, scoped buckets and auditable requests.

03

On-prem API access

Publish selected internal API operations through the same secure gateway without making private services publicly reachable.

04

Identity & policy

Issue scoped API keys, set per-client limits and apply least-privilege policies consistently across every access type.

05

Verifiable audit trail

Record data queries, object operations, API calls and configuration changes in an append-only, hash-chained log.

06

AI-ready access

Let agents use approved data, storage and API capabilities through MCP inside strict, observable boundaries.

A SMALLER ATTACK SURFACE

Your internal systems stay private.

OPrA runs alongside your systems, within the network boundary you control. External consumers talk HTTPS to one governed gateway—not directly to databases, storage endpoints or internal APIs.
