Your data stays put.
Pipeline stays in control.
Sentra is a distributed data preprocessing platform that runs lightweight agents on your infrastructure. Orchestrate jobs, ensure compliance, and maintain data residency — all without moving sensitive data.
Where pipelines break down
Problems rarely announce themselves. They accumulate in assumptions no one documented, in steps that succeeded quietly when they shouldn't have.
No visibility into what ran where
Jobs execute on remote agents. Without explicit reporting, you can't tell which machine processed which chunk.
Plugins with no integrity
Code that runs close to sensitive data needs verification. An unsigned plugin is a trust assumption you can't audit.
Pipelines that continue past failures
If a step fails and nothing stops the job, data moves forward anyway. Silent continuation is silent risk.
No proof of what happened
Auditors ask: what ran on this data? Without an explicit record, you're guessing.
Sentra makes every step explicit
—before problems become incidents.
Control plane sees outcomes. Not data.
Sentra orchestrates jobs, evaluates results, and tracks agent health. It knows what ran, whether it passed. It never receives the data processed.
Control Plane
A hosted backend that dispatches jobs, stores policy, tracks agent health, and records outcomes. Orchestrates everything — receives nothing sensitive.
- Job orchestration & scheduling
- Policy management & version control
- Agent health monitoring
- Audit logging & compliance
Agent
A Go binary that runs on your infrastructure. Downloads signed plugins, executes in sandbox, reports outcomes. Data stays where it lives.
- Runs on-premise or in your cloud
- Executes signed & verified plugins
- Sandboxed execution environment
- Reports outcomes, not data
Where teams use Sentra
Processing happens close to the data, with a central record of what occurred.
PII redaction at the source
Run redaction plugins on the machine where data lives. Control plane records the outcome. Nothing sensitive moves through the backend.
ML dataset preparation
Validate and transform datasets before training. Track lineage per job. Catch contamination before it reaches a model.
Regulated data pipelines
Apply policy-driven preprocessing. Produce timestamped records of every decision without copying data to a central system.
Retail catalog comparison
Automate product matching across platforms. Deduplication and coverage analysis, all with local execution.
Built for teams that own their data
Not a managed pipeline. Not a cloud ETL. Sentra is for teams where data residency is a hard constraint.
Data & ML engineers
Orchestrate preprocessing across distributed machines. Track what ran, on what data, whether it passed — without centralising data.
Privacy & security teams
Enforce redaction policy at the source. Every plugin signed. Every execution logged. No data leaves the processing environment.
Platform & infra teams
Deploy a single agent binary. Manage plugins centrally. Get consistent preprocessing behaviour across every environment.
How it's structured
Three components with distinct responsibilities. Each can be understood, audited, and replaced independently.
Agent
A Go binary that runs on your infrastructure. Downloads signed plugins, executes in sandbox, reports outcomes.
Control plane
Hosted backend that dispatches jobs, stores policy, tracks agent health, records outcomes. Receives nothing sensitive.
Plugins
Signed, sandboxed executables that do the work. Uploaded once, verified automatically on every agent.
What Sentra guarantees
Every design decision traces back to one requirement: prove what happened to your data, without centralising the data itself.
Cryptographic verification
Every plugin signed with Ed25519 key. Agent verifies at startup and before execution.
Sandboxed execution
Each plugin runs with enforced memory, CPU, and wall-clock limits.
Explicit outcomes
Every job produces a recorded outcome. Pipeline stops on failure.
