Northbeams vs Strix

Northbeams and Strix 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

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.

Strix

Strix runs multi-agent Think-Plan-Act loops that scan infrastructure, attempt exploitation, and return findings backed by working PoCs — so your team reviews confirmed vulnerabilities rather than triaging noise. The vendor page describes CI/CD integration and PR-level fix suggestions, which means security gates can live inside the same pipeline where code ships. Self-hosted and air-gapped deployment options are confirmed, making it viable for teams with data residency requirements. The agentic model works well when scope is defined and targets are enumerable — cloud misconfigs, known CVE classes, API surface. Where it strains is against novel logic flaws and business-layer vulnerabilities that require context no automated agent carries.

Pros	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.	Autonomous agents return findings with working proof-of-concept exploits attached, so your team skips the manual reproduction step that typically consumes days between scan and fix. Multi-agent Think-Plan-Act architecture executes attack sequences without human steering at each step, which means a single security engineer can run coverage across an infrastructure that would otherwise require a full red team. CI/CD pipeline integration with PR-level fix suggestions keeps security findings inside the developer workflow, so vulnerabilities surface at the same moment code changes ship rather than weeks later in a quarterly report. Self-hosted and air-gapped deployment is confirmed by the vendor, which means teams with data residency requirements or classified environments can run the full agent stack without sending target data to an external service. Open-source codebase allows security teams to audit exactly what the agents execute, which means you are not trusting a black-box scanner on infrastructure you cannot afford to have probed incorrectly.
Cons	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.	Agents operating within Think-Plan-Act loops depend on the target being within the enumerable attack surface the model understands — business logic vulnerabilities and multi-step application flows that require domain context produce no findings, and teams with that testing requirement add a manual penetration tester alongside the tool rather than replacing the workflow. Automated exploitation against production targets carries risk that misconfigured scope definitions translate directly into unintended impact; teams running Strix against live environments report needing explicit scope guardrails and staging-first policies before touching production, adding operational overhead the tool does not eliminate. When the primary gap is compliance-driven manual testing with a signed attestation from a human pentester, Strix's autonomous output does not satisfy the requirement regardless of finding quality — teams in those regulatory contexts switch to a managed DAST or manual pentest vendor for the compliance artifact and run Strix separately for continuous coverage.

Bottom line

Strix is open source; only Northbeams exposes a public API. Choose based on which difference matters most for your workflow.
