Mac

N3O is an AI security architecture workbench for macOS covering the full assessment lifecycle: discovery, architecture review, evidence-backed assurance, threat modeling, exposure quantification, signed deliverables, and annual reassessments—entirely on your Mac. FIND SHADOW AI: Sweep repositories before scoping to detect model providers, agent frameworks, MCP servers, vector stores, and credentials. It isolates autonomy risks such as tool calling, shell access, code execution, disabled approvals, and unbounded loops, exporting to CSV, JSON, or CycloneDX AI-BOM. ARCHITECTURAL REVIEW OVER CHECKLISTS: Model components and data flows to surface critical authority paths via bounded static analysis: untrusted inputs reaching sensitive tools, shared identities, missing user context, and excess privilege. Export system maps to Mermaid or Graphviz. 17 FRAMEWORKS OR CUSTOM STANDARDS: Assess against NSA/CISA, OWASP (Agentic, LLM, NHI, AISVS, MCP), CSA (MAESTRO, AICM), NIST (AI RMF, CAISI), MITRE ATLAS, ISO/IEC 42001, AIUC-1, IMDA, and the EU AI Act across 182 severity-weighted controls. Author custom standards or import client baselines as immutable, signed versions to prevent retrospective score changes. FOUR STATIC SCANNERS: Audit MCP configs, agent source code, repositories, and execution traces. Surface unapproved tool calls, transcript secrets, injection-shaped outputs, and loop storms directly into your assessment questionnaires. EVIDENCE-BACKED ASSURANCE: Separate claimed posture from verified assurance. Tie findings to content-hashed evidence with freshness windows; unverified claims yield zero assurance, explicitly highlighting unproven controls in final reports. THREAT MODELING & QUANTIFIED REMEDIATION: Run STRIDE or PASTA models, project the impact of targeted fixes, and estimate annualized loss ranges with FAIR-style risk modeling. Every remediation crosswalks to ISO/IEC 27001:2022 Annex A and NIST SP 800-53 Rev. 5. HARDEN FUTURE BUILDS: Generate context-aware AGENTS.md and CLAUDE.md guardrails tailored to the client’s architecture and open vulnerabilities to enforce secure coding in subsequent commits. PRACTICE MANAGEMENT: Manage evidence requests, peer reviews, risk acceptances, and supplier caps across a unified local portfolio. Track expirations and generate delta reassessments showing remediated, regressed, and lingering risks. VERIFIABLE DELIVERABLES: Export to Markdown, PDF, OSCAL (assessment-results and POA&M), SARIF, CycloneDX, Jira CSV, and GitHub Issues. Cryptographically sign deliverable bundles using an Ed25519 identity verifiable independently of N3O, with built-in post-handover tamper detection. LOCAL, PRIVATE, AND CONTROLLED: - Runs on-device via Apple Intelligence with an optional BYOK cloud tier (off by default). - Zero telemetry, no accounts, and no background server calls. - Target-passive: never executes analyzed code or contacts artifact addresses. Optional runtime probes strictly require written client authorization with host and expiration constraints. Control statements are practitioner-authored interpretations of cited publications. N3O is not affiliated with or endorsed by any standards body and issues no formal certifications. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ https://jamsoftinc.com/privacy-policy-n3o

What's new Data safety: delete now asks first. Edit ▸ Undo reverses deletes, archiving, renames, duplicates, and every answer change. A failed save shows a banner with Retry instead of being silently dropped. Daily backups and Settings ▸ Data add backup, restore, and full export and import. Home: search, type and status filters, sort, an archive shelf, and Rename and Duplicate on every card and rail row. Menus and Mac integration: new Assessment and Go menus, ⌘1–⌘7 for the steps, ⇧⌘E to export a PDF, ⌘P to print, and ⌘F for search. The window reopens where it was left. Double-clicking a .n3ohandoff file in Finder opens the import sheet, which warns before overwriting newer local work. Reports: a Share button sends the PDF to Mail, Messages, or AirDrop. PDF pages now carry a title and classification header and a "Page X of Y" footer, set in Settings ▸ Reports. Horizontal rules, italics, code, and links now render properly. Questionnaire: text search, framework and severity filters, Clear Answer, and multi-line notes. Reports fold a note onto one line wherever it sits inside a list. Scanners: you can drop a file on each card. A scan keeps running and keeps its results when you leave the screen, and Scan Again re-runs it. Results filter by severity and text. Links: a finding opens its control in the questionnaire, and a threat in the risk panel scrolls to that exact threat. Portfolio: Swift Charts show risk, assurance, compliance, and movement since baseline. Clicking a bar lists the assessments behind it. Accessibility and Dark Mode: VoiceOver labels, values, and selected states on the shared components, and full Dark Mode with a choice in Settings ▸ General. Report previews stay on a white page.
