Cerbi prevents sensitive data, schema drift, and noisy telemetry from entering your logs before they reach observability platforms like Splunk, Datadog, or Azure Monitor.
Most observability tools only process logs after ingestion.
By that point, costs have already occurred, sensitive data has already spread, and compliance issues already exist. Cleaning up downstream is reactive and incomplete.
Sensitive data leaking into logs
PII, PHI, and credentials reach observability platforms before anyone notices. Downstream cleanup is expensive, incomplete, and does not remove data already ingested.
Schema drift breaking dashboards
Log structures change without coordination across teams. Alerts break, dashboards go stale, and engineering hours are lost diagnosing inconsistencies.
Observability costs growing unchecked
Noisy, ungoverned logs inflate ingestion volumes in Splunk, Datadog, and Azure Monitor. Most teams have no visibility into what is actually being sent.
No audit trail for logging policy
Compliance teams cannot demonstrate what governance controls exist, when policies changed, or whether violations were detected. Audits require manual evidence gathering.
Cerbi addresses these problems earlier in the lifecycle — before logs leave the application.
Telemetry pipelines lack governance.
Modern applications emit large volumes of telemetry. Most observability systems ingest logs with no policy enforcement, validation, or governance controls.
Problems surface downstream after ingestion.
Govern telemetry before ingestion.
Cerbi inserts a governance layer into the telemetry pipeline. Events are validated, governed, and enriched before reaching observability platforms.
Use CerbiStream as a native logger, or add Cerbi governance to your existing logging framework.
Telemetry becomes governed data.
Telemetry becomes structured, compliant, and predictable. Teams gain visibility into governance posture while retaining their existing observability tools.

Common Problems
Governed telemetry pipeline
Cerbi governs telemetry before it reaches observability platforms.
Cerbi does not replace your observability platforms. It governs telemetry before ingestion, ensuring only validated, compliant data reaches your existing tools.
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 your application. It validates fields, attaches governance metadata, and applies policy controls before telemetry leaves the process. Use it as a native logger or integrate it with an existing logging framework.
CerbiStream integrates with Microsoft.Extensions.Logging, Serilog, and other existing logging frameworks.
CerbiShield
Governance control plane
CerbiShield is the governance control plane that manages rules, policies, and audit visibility across all environments, providing centralized configuration and analytics for telemetry governance.
CerbiStream enforces governance at runtime. CerbiShield manages governance across the platform.
Most governance issues are resolved before production.
Cerbi does not have to run heavily in production to provide value. Governance runs across the development lifecycle — most violations are identified and resolved during local development and CI.
Local Development
Governance rules run in the developer's local environment. Violations surface immediately during normal development before code is ever committed.
CI Pipeline
Governance validation runs as part of the build. Violations block the pipeline and become standard backlog items resolved during normal sprint work.
Staging
Runtime governance validates telemetry under real application behavior. Edge cases and environmental differences are caught before reaching production.
Production
Production enforcement is a lightweight safety net. The heavy governance work has already been done. Runtime overhead is minimal.
Violations discovered in development and staging become standard engineering backlog items. Production enforcement acts as a final safety net with minimal runtime overhead.
Everything you need to govern telemetry
A complete governance control plane for your telemetry data. Define policies, validate at runtime, track violations, and maintain audit-ready compliance.
Built for engineering organizations running production systems at scale.
Standardize telemetry across services and teams.
- Enforce consistent log schemas organization-wide
- Prevent ungoverned telemetry from reaching downstream systems
- Policy-driven controls that work with existing logging frameworks
Prevent sensitive data leakage and enforce logging policies.
- Block PII, PHI, and credentials before they leave the service
- Immutable audit trails for SOC 2, HIPAA, and GDPR requirements
- Policy changes tracked with full history and approval records
Reduce observability costs and improve operational consistency.
- Governance posture visible and measurable across teams
- Reduce log ingestion volume by filtering noise before the pipeline
- Integrate governance into CI without blocking developer velocity

Illustrative examples based on observed deployments and internal testing.
Designed for production environments
Cerbi runs within your infrastructure. Log payloads, telemetry, and metadata are never transmitted outside your environment.
Deployment & Licensing Truth
CerbiShield and the governance control plane are deployed entirely in your tenant. Your log data never leaves your infrastructure.
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 within your tenant so telemetry never leaves your environment.
Encryption at Rest & Transit
AES-256 file encryption for fallback logs. Cerbi is designed to fit within TLS-secured infrastructure.
Automatic PII Redaction
Rule-based redaction identifies and masks sensitive fields before telemetry reaches its destination.
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 as they occur with structured tags your existing pipelines can forward.
Immutable Audit Logs
Append-only audit trails designed for WORM-capable storage, keeping all changes tamper-evident.
