Govern logging behavior
at the source.
Control what applications are allowed to log before it leaves the application.
Set rules. Enforce them. Prove it.
If you're relying on ingest masking, you're already too late.
Real incidents. Same root cause.
Sensitive data was written to logs before any protection was applied.
Credentials captured in logs
Tokens and credentials were captured in internal logs during debugging and support workflows.
Sensitive data was written first and trusted to be masked later.
Cerbi prevents sensitive fields from being logged before it leaves the application.
Passwords written before hashing
User passwords were written to internal logs before hashing completed.
Logging occurred before security controls were applied.
Cerbi enforces logging policy at emission time. Unsafe fields never reach the pipeline.
Session tokens in support artifacts
Session tokens appeared in diagnostic files shared during support workflows.
Sensitive data was collected without restriction at creation time.
Cerbi blocks sensitive fields before they leave the application, not after.
Masking rules missed new formats
Pattern-based masking failed to match new data formats, allowing sensitive values through.
Downstream cleanup depended on incomplete, brittle rules.
Cerbi enforces structured logging policy instead of fragile regex pipelines.
Inconsistent coverage across platforms
Logs were routed to multiple platforms, each with different masking rules and gaps.
Governance existed in some destinations but not others.
Cerbi enforces logging behavior at the source, consistent before it leaves the application.
Every incident started with data that shouldn't have been logged.
The distinction that matters
Cleaning up after vs. preventing unsafe logging entirely
Traditional Logging
- Logs contain raw sensitive data
- Masking happens downstream
- Multiple tools, inconsistent rules
- Audit requires cleanup
Cerbi
- Logs are compliant at creation
- Policies enforced automatically
- One standard across all apps
- Audit-ready by default
Cerbi does not clean logs after the fact. Cerbi controls what applications are allowed to log in the first place.
Why teams adopt Cerbi
Three problems that source-side governance solves.
Sensitive data in logs is a breach waiting to happen.
PHI, PII, secrets, and credentials are routinely emitted by application code before it leaves the application. They end up in Splunk, Datadog, and Azure Monitor, where access controls are loose and retention is long.
Schema drift breaks dashboards and hides audit gaps.
When teams log inconsistently, required fields go missing, alerts fire on noise, and compliance audits expose gaps. Logging policy needs to be enforced before it leaves the application.
Ungoverned logging wastes ingestion budget.
Unfiltered log volume inflates Splunk and Datadog costs with noise nobody reads. Blocking irrelevant events and redundant fields before it leaves the application reduces ingestion at the source.
Logging behavior is governed inside your application, before it leaves the application.
Cerbi intercepts every log event between your framework and the underlying provider. No call-site rewrites. No pipeline replacements. No infrastructure changes.
Application
Your .NET service
Log emitted normally via MEL, Serilog, or NLog.
Cerbi Governance Layer
In-process, no pipeline changes
Logging policy applied at emission time. Sensitive fields blocked. Schema validated. Violations tagged.
Governed Payload
Only clean, compliant data continues
Redacted fields never enter the pipeline.
Your existing destinations
What happens at each stage
Log emitted normally
Your application code calls _logger.LogInformation() or equivalent. No changes needed to existing call sites.
Logging policy applied in-process
CerbiStream intercepts the event inside the logging provider. Rules from your cerbi.json profile are evaluated at emission time.
Sensitive fields blocked before leaving
Fields matching DisallowedFields are blocked. Fields matching MaskFields are partially redacted. Violations are tagged on the event.
Only governed payload continues downstream
The sanitized log event is forwarded to your existing sinks: Splunk, Datadog, or wherever you send logs today.
Program.cs
builder.Logging.AddCerbiStream();One line of setup. No changes to existing log call sites. No pipeline migration.
Before vs. after governance
Behavior enforcement before it leaves the application.
Logging policy is applied at emission time, not after data reaches your observability platform.
GovernanceViolations
Logging policy is defined in a JSON profile and enforced at runtime. No pipeline changes, no call-site rewrites.
One unified governance platform. Three components.
CerbiStream enforces governance in the application. CerbiShield manages it across the platform. CerbiScoring tracks it over time.
CerbiStream
In-app enforcement
The .NET logging provider that enforces governance rules in-process. Blocks sensitive fields, redacts values, and tags violations before any log leaves the application.

Governance management and deployment
Central dashboard for managing governance profiles, monitoring violations, and deploying policy updates across environments. Includes RBAC, audit history, and Entra SSO.

Visibility and posture tracking
Tracks governance health, violation trends, and rule relaxation history across services. Gives security teams a quantified view of logging compliance over time.

Standardize telemetry across every service.
- Enforce consistent log schemas organization-wide without touching existing code
- Prevent ungoverned telemetry from reaching Splunk, Datadog, or other sinks
- Policy-as-code that lives in version control alongside your application
Stop sensitive data leakage before it happens.
- Block PHI, PII, credentials, and secrets at the application boundary
- Immutable, append-only audit trails for SOC 2, HIPAA, and GDPR requirements
- Full policy change history with actor tracking and approval records
Reduce cost, improve audit readiness.
- Governance posture visible and measurable across all services and teams
- Cut ingestion costs by filtering noise and redundant fields before the pipeline
- Integrate governance validation into CI without blocking developer velocity
Designed to be safe for enterprise deployment.
Cerbi is purpose-built for environments where data residency and access controls matter. Your logs stay in your infrastructure, always.
Runs inside your infrastructure
Cerbi is deployed within your tenant. Log payloads, sensitive fields, and governance metadata never leave your environment.
Log data stays in your tenant
No relay servers. No third-party log forwarding. Governance happens in-process. Your observability data stays where it belongs.
Works with your existing observability stack
Sits in front of Splunk, Datadog, Azure Monitor, Elastic, and OpenTelemetry. No pipeline replacement required.
Governance enforced before ingestion
Every log event is validated at emission time, before it leaves the application, not after it reaches a downstream platform.
No pipeline replacement required
Cerbi adds governance without changing how logs flow. Your existing logging infrastructure continues to work unchanged.
Structured, version-controlled policies
Governance rules are JSON files that live in source control alongside your application code. No proprietary config systems.
Your logs should not carry sensitive data.
Cerbi enforces logging policy inside your application before data reaches downstream observability platforms. Works with your existing stack. No pipeline changes.
