Works with your stack

No rip-and-replace.

Cerbi plugs into what you already use.

What Cerbi is not

A control layer.
Not another tool.

Cerbi makes your existing tools actually work.

Not a logging platform

Cerbi does not store, index, or visualize logs.

Not a SIEM

Cerbi does not analyze threats or correlate security events.

Not another observability tool

Cerbi does not replace your existing stack.

Cerbi governs what enters your existing tools, so those tools can do their job with clean, consistent data.

Cerbi governance sits before ingestion. Your routing stays unchanged.

Logger integrations

Native adapters for all major logging frameworks.

Each adapter applies governance rules using the framework's existing extension points. No forked logging libraries. No rewrites.

MELSupported

Built-in logging abstraction layer. Add Cerbi.MEL.Governance as a provider.

NuGet package

SerilogSupported

Structured logging framework. Add Cerbi.Serilog.Governance as a sink/enricher.

NuGet package

NLogSupported

Flexible logging platform. Governance target integrates without replacing existing targets.

NuGet package

Microsoft.Extensions.Logging

// Microsoft.Extensions.Logging  -  1 line
builder.Logging.AddCerbiStream();

Serilog

// Serilog  -  governance enricher/sink
Log.Logger = new LoggerConfiguration()
    .Enrich.WithCerbiGovernance()
    .WriteTo.Console()
    .CreateLogger();

NLog

<!-- NLog  -  governance target in nlog.config -->
<targets>
  <target name="cerbi" type="CerbiGovernance" />
</targets>
<rules>
  <logger writeTo="cerbi,logfile" />
</rules>

Destination support

Keeps working with your existing observability stack.

Cerbi doesn't replace your logging infrastructure. It governs what's emitted before it reaches your sinks.

Java / Maven Central - Alpha

Alpha

Source-side logging governance for Logback and Log4j2. Published to Maven Central as v0.1.0. Apply governance profiles before log events leave the application - redact sensitive fields, tag violations, enforce required metadata, and generate governance evidence. Not production-ready. Feature parity with .NET is not claimed.

Source-side logging governance

Runtime redaction and violation tagging

Governance profile enforcement

Required metadata validation

Governance evidence metadata

Compatible with existing observability sinks

Node.js / npm

Alpha

Winston and Pino transports that evaluate each log event against a JSON ruleset and annotate it with governance status - mode, violations, score impact - without blocking log flow.

Evaluates events against JSON rulesets

Emits mode, profile, violations, and score impact

Hot reload of rulesets via file polling / watching

Never blocks logging on missing or invalid config

Compatible with existing Winston and Pino transports

Enriches events with CerbiShield scoring fields

Winston

npm install @cerbi/winston-governance

Pino

npm install @cerbi/pino-governance

Winston example

import winston from "winston";
import { CerbiGovernanceTransport } from "@cerbi/winston-governance";

const logger = winston.createLogger({
  transports: [
    new CerbiGovernanceTransport({
      rulesetPath: "./ruleset.json",
      pollIntervalMs: 2000,
    }),
    new winston.transports.Console(),
  ],
});

logger.info("user signup", { userId: "123", password: "plaintext" });
// → password field tagged as violation, score impact emitted
