Air-gapped Integration Platform
An air gapped integration platform runs data sync jobs inside a closed network. You set it up by loading local container images, packages, and identity rules offline. Many teams start by copying all software images onto local storage drives. They then create shared admin accounts so services can talk to local databases. When roles stay too broad, one bad script can drop tables or leak records. How an air gapped integration platform works Closed networks have no route to the public web at any

An air gapped integration platform runs data sync jobs inside a closed network. You set it up by loading local container images, packages, and identity rules offline. Many teams start by copying all software images onto local storage drives. They then create shared admin accounts so services can talk to local databases. When roles stay too broad, one bad script can drop tables or leak records.
How an air gapped integration platform works
Closed networks have no route to the public web at any time. Every tool, container image, and code package must live inside your local servers. Teams set up a private registry to hold all approved software builds. They also run a local directory service to check user and machine identities.
The platform pulls data from one local app and sends it to another. To do this, worker nodes need keys or roles for each data store. Admins set up service accounts inside the local database and message queue. Each worker uses these saved keys to log in and run sync jobs.
Network rules block all traffic that tries to leave the local zone. Firewalls inside the zone only let worker nodes reach specific database ports. Admins must load software updates by hand after checking each file signature. This strict process keeps outside threats away from your private systems.
What native network isolation solves and what it misses
An isolated network stops outside attackers from reaching your private data stores. It also stops local apps from sending private data to outside servers. Network firewalls and local roles check who can log in to a host. They make sure only known worker nodes and local admins can start sessions.
Still, network walls do not inspect what happens inside an active session. Once a worker or admin logs in, the database trusts every query. A broken sync job can still overwrite thousands of rows by mistake. An admin who logs in to fix a bug can read raw data. Native roles decide who gets in, not what each command does in flight.

Why local admin work creates risk in closed zones
When a sync job fails, engineers must log in to check the error. In a closed zone, teams often share static database keys to save time. Many engineers end up using the same high-level role to fix broken jobs. Audit logs only show the shared role name, not the real person.
Without query checks, a quick fix can turn into an outage fast. An engineer might run a wide update statement without a row limit. Also, query results often return raw emails, phone numbers, or card numbers. Local isolation keeps data inside the building, but it does not control live queries.
Govern statements and responses across databases and APIs
Good config and scoped roles are needed setup. They do not check single queries in flight or mask sensitive fields in returned rows. Across Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, and internal HTTP endpoints, hoop.dev sits inline in the protocol beside each supported service as an open-source proxy, a sidecar for your database or API. For every query or command an AI agent or engineer runs against production, hoop.dev decides to pass, mask, block, or hold it for human approval.
First, hoop.dev guardrails block banned queries before they run or hold risky ones for review, and hoop.dev data masking rewrites matched sensitive values in responses in memory. Furthermore, hoop.dev holds SOC 2 Type II and is open source on GitHub.
Frequently asked questions
How do teams update software inside a closed network?
Teams download patches on an outside machine and check the file signatures first. Then they move the verified files into the local registry using secure media.
Why are static service keys risky on an isolated network?
Static keys never expire on their own and often hold broad read rights. If a local script or user grabs that key, they can read everything.
Can local compliance rules require data masking on internal networks?
Yes, privacy rules often limit who can read sensitive fields inside a company. Masking rewrites matched emails, phone numbers, and card numbers in query results.
