Telemetry Governance Layer

Stop bad telemetry
at the source.

Cerbi is a telemetry governance platform that enforces policy before data reaches your observability tools.

Cerbi governs telemetry before it reaches observability platforms.

This prevents sensitive data leaks, schema drift, and uncontrolled ingestion before events propagate downstream.

Telemetry pipelines have no governance.

Application Services
Logger
Observability Platform

Modern applications emit huge amounts of telemetry. Most observability systems ingest logs with no policy enforcement, validation, or governance.

Common issues appear downstream.

Sensitive data leaks into logs
Schema drift breaks dashboards
Observability costs grow uncontrollably
Audit teams lack traceability

Introduce governance before ingestion.

Cerbi Governance Layer
Observability Platforms

Cerbi inserts governance into the telemetry pipeline. Events are validated, governed, and enriched before reaching observability platforms.

Use CerbiStream directly or add Cerbi governance to your existing logging framework.

Stop it at the source.

Telemetry becomes governed data.

Observability Platform

Telemetry becomes structured, compliant, and predictable. Teams gain visibility into governance posture while keeping their existing observability tools.

Cerbi governs telemetry before it reaches observability platforms.

Works with your existing logging stack

Cerbi does not replace your logging framework. Applications can emit telemetry using CerbiStream directly or integrate Cerbi governance with existing frameworks:

Microsoft.Extensions.LoggingSerilogNLog

Observability destinations remain unchanged.

The Cerbi Platform

Cerbi is a telemetry governance platform with two primary components: CerbiStream, the runtime enforcement SDK, and CerbiShield, the governance control plane.

CerbiStream

Runtime enforcement SDK and native logger

CerbiStream is the runtime enforcement SDK that runs inside applications. It validates fields, attaches governance metadata, and applies policy controls before telemetry leaves the application. CerbiStream can be used as a native logger or integrated with existing logging frameworks.

Structured logging
Async channel dispatch
File fallback logging
Optional AES encryption and rotation
Governance metadata tagging

CerbiStream integrates with existing logging frameworks including Microsoft.Extensions.Logging and Serilog.

Control Plane

CerbiShield

Governance control plane

CerbiShield is the governance control plane that manages rules, policies, and audit visibility across all environments. It provides centralized configuration and analytics for telemetry governance.

Governance rule profiles
Rule deployments across environments
Violations explorer
Governance analytics and reporting
Audit history and activity tracking
RBAC and enterprise SSO (Entra)
Platform health monitoring

CerbiStream enforces governance at runtime. CerbiShield manages governance across the platform.

CerbiShield Control Plane

Governance lifecycle

A continuous workflow from rule definition through compliance monitoring and audit.

Step 1: Define rules
Step 1

Define rules

Create governance rules that specify required fields, forbidden patterns, and validation constraints for telemetry events.

Logs became a data system.

Logs now contain user identifiers, operational context, security signals, and application state. However, unlike databases and APIs, logs typically have no governance controls.

User identifiers

User IDs, session tokens, emails

Operational context

Request metadata, timing, paths

Security signals

Auth events, access patterns, tokens

Application state

Errors, performance metrics, events

Unlike databases or APIs...

  • -No schema enforcement
  • -No access controls
  • -No audit trails
  • -No governance policies

Cerbi introduces...

  • +Governance rules and validation
  • +RBAC and enterprise SSO
  • +Immutable audit history
  • +Deployment control and versioning

Cerbi introduces governance policies before telemetry enters observability pipelines. This prevents bad telemetry from propagating downstream.

Enterprise-Grade Security

Built for compliance from day one. Cerbi gives you the guardrails and evidence you need to pass real audits.

Deployment & Licensing Truth

Tenant-Hosted Governance

CerbiShield and the governance control plane are deployed entirely in your tenant. Your log data never leaves your infrastructure.

Log Volume Licensing

Licensing is based on governed log events per month.

Usage is counted per billing month.

If you exceed your tier in a month, Cerbi continues operating for the rest of that month.

Starting the next billing month, Cerbi enforces your tier cap.

Once the cap is reached, additional events are not accepted until you upgrade.

Your applications keep running normally. Only Cerbi event intake is affected.

Tenant-Hosted

Your infrastructure, your control. Cerbi runs entirely in your tenant so logs stay in your environment.

Encryption at Rest & Transit

AES-256 file encryption for fallback logs. Cerbi fits into TLS-secured infrastructure.

Automatic PII Redaction

Rule-based redaction identifies and masks sensitive fields before they reach your log destinations.

Compliance Aligned

Built-in audit trails designed for SOC 2 Type II, HIPAA, GDPR, and ISO 27001 logging controls.

Real-Time Violation Alerts

Catch governance violations quickly with structured tags your existing pipelines can forward.

Immutable Audit Logs

Append-only audit trails designed for WORM-capable storage, making changes tamper-evident.

Cerbi governs telemetry before ingestion.

By introducing governance before telemetry reaches observability platforms, Cerbi ensures data remains structured, compliant, and predictable.
