Agent Governance Toolkit and Northbeams are both guardrails & safety tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.
Northbeams sits between your workforce and their AI tools, classifying what's running, blocking what shouldn't be, and generating the evidence chain your SOC 2 or HIPAA auditor will ask for. The browser-based agent installs without network changes, so IT doesn't need a procurement cycle to get visibility. Discovery is ungated, which means you can map your shadow AI footprint before committing to enforcement. The ceiling appears when your environment scales past a single site or when you need MCP agent governance — those capabilities are paid-only features. Teams running large multi-site deployments report that per-seat policy management becomes the operational bottleneck.

Platforms
Available in Python, TypeScript, Rust, Go, and .NET
First toolkit to address all 10 OWASP agentic AI risks with deterministic, sub-millisecond policy enforcement
Framework-agnostic from day one, hooks into framework native extension points so adding governance does not require rewriting agent code
Available across language ecosystems with TypeScript SDK through npm and .NET SDK through NuGet
Structured as monorepo with independently installable packages allowing incremental adoption
Ships with 9,500+ tests and includes SLSA-compatible provenance, OpenSSF Scorecard tracking, CodeQL scanning, and Dependabot dependency monitoring
Agent deploys without network changes or procurement approval, so a security team can have full shadow AI inventory running in hours rather than after a six-week firewall project.
Real-time PII, credential, and source-code interception fires before data leaves the browser, which means you catch the leak before it becomes a breach notification obligation.
Automated generation of SOC 2, HIPAA, and EU AI Act audit evidence means compliance reviews don't require a two-week manual log reconstruction before every auditor call.
Per-tool allow/block/sandbox policies for MCP agent access, so engineering teams using Cursor or Claude Desktop don't operate in a governance blind spot while the rest of the org is covered.
Discovery tier is ungated, which means you can produce a complete AI tool inventory and make the business case for enforcement before spending a dollar — removing the 'prove it first' blocker most security budgets impose.
Cons
Provides application-level governance, not OS kernel-level isolation; policy engine and agents run in same process, so production recommendation is to run each agent in separate container
Toolkit is currently in public preview and may have breaking changes before GA
Real-world production adoption evidence still limited (announced April 2026)
Browser-agent coverage means any AI workload running outside the browser — CLI tools, server-side agents, API integrations — is invisible to Northbeams; teams with significant non-browser AI usage will maintain a separate inventory for those surfaces and live with two parallel governance systems.
MCP agent governance and Fleet (multi-site policy management) are paid-only features, so organizations that deploy on the free tier and then discover their primary risk is in coding agents or distributed sites face a forced upgrade decision mid-rollout rather than before it.
Teams that outgrow per-tool policy management at scale — typically when seat counts push into the hundreds across multiple locations — report that policy administration becomes a recurring manual burden; at that inflection point, organizations with dedicated security engineering staff typically migrate to a network-layer DLP or CASB that handles enforcement at the infrastructure level rather than the browser.
Bottom line
Agent Governance Toolkit is free while Northbeams is paid. Choose based on which difference matters most for your workflow.
