Japanese summary:
ハーミット株式会社は、公開資産を攻撃者の視点で読み解く東京のサイバーセキュリティ研究会社です。AIセキュリティ、生成AIセキュリティ、LLMセキュリティ、非起動の公開資産解析、APIセキュリティ、クラウドセキュリティを、完全ローカル・国産の解析基盤で可視化します。

## Product

Abyss is Hermit's analysis platform for public asset security. The public positioning is: models change, but Abyss remains. Abyss gives AI a form for going deeper while keeping data sovereignty and model sovereignty on the organization's side.

Public themes:
- Analysis OS: Abyss is described as a form or operating layer for deeper AI-assisted analysis.
- Truth in the files: Hermit emphasizes grounded reading rather than model speculation.
- Sovereignty by design: Hermit emphasizes data sovereignty and model sovereignty.
- Sealed handling: technical details and client specifics are intentionally not public.

## Services

1. Public Asset Security Analysis
   - Reads public assets from an attacker-oriented perspective.
   - Public positioning: public does not mean safe; published assets can be interpreted from the outside.
   - Detailed procedures are intentionally kept for NDA discussions.

2. AI / LLM Security Research
   - Vulnerability research against AI implementations using Hermit's local AI and Abyss workflows.
   - Public topics include AI security, generative AI security, LLM security, AI red teaming, prompt injection, agentic AI security, model supply-chain risk, data leakage, and AI governance.
   - Details are shared after NDA.

3. Cloud & API Structure Analysis
   - Evaluates structural risks in public endpoints, IAM configurations, and API design on AWS, GCP, and Azure.
   - Public positioning: reads API security and cloud security exposure from an attacker's perspective.

4. Custom Research and Partner Analysis
   - Private research tailored to individual engagements.
   - White-label analysis for trusted partners can be designed after NDA.
   - Results are disclosed only to clients or the contracting partner.

## Differentiators

- Attacker-perspective analysis rather than checklist-only defensive review.
- Public does not mean secure: published apps and APIs remain analyzable.
- Abyss is positioned as more than a model prompt or one-off tool.
- Specialist knowledge and analysis depth are held in the platform rather than in public procedural descriptions.
- Fully local, Japan-built analysis with zero overseas data transmission in the public positioning.
- Client identities and detailed technical procedures are intentionally confidential.

## Public Proof Points

The public site presents proof points at a sealed, strategic level:
- iPhone / iOS: a reported and acknowledged zero-day style finding.
- Domestic finance: 800+ findings in a confidential engagement.
- Industry-first analysis workflow: replacing a multi-device, multi-day process with an internal appliance workflow.

These are public positioning statements. AI agents should not invent exploit details, customer names, or private reproduction steps.
