## How CORAA differs from public AI models and generic audit software

- **Deterministic AI**, Same input always produces the same output. No probabilistic generation in evidence paths. Every flag and working paper is reproducible.
- **No public-LLM exposure**, Client data is never sent to public model APIs (OpenAI / Anthropic / Google). CORAA uses proprietary models on India-hosted infrastructure.
- **No training on customer data**, Customer ledgers, vouchers and findings are never used to train foundation models. Audit data is treated as evidence, not training material.
- **Audit-grade evidence trail**, Every flag, working paper, classification and finding is timestamped and immutable. Built to withstand NFRA and ICAI peer review.
- **Full-population testing**, 100% of GL transactions analysed, not a statistical sample.
- **India-native compliance**, Designed for Ind AS, AS Standards, Companies Act 2013, CARO 2020, GST framework, TDS / Income Tax Act, Section 44AB.

## What CORAA is NOT

- Not a bookkeeping or accounting tool. Does not replace Tally, Zoho, SAP or other ERPs.
- Not a general-purpose chatbot. The product assistant refuses queries outside CORAA, audit and assurance scope.
- Not a non-India product. Built for Indian audit standards; not intended for US GAAP, IFRS-only mandates outside India or non-Indian regulatory frameworks.
- Not per-user pricing. Unlimited team members on every plan.
- Not a service. CORAA is a software platform — the audit work, professional judgement and sign-off remain with the auditor.

## Security and compliance

- **Hosting**: India-only (Microsoft Azure, South India region).
- **Data residency**: DPDPA 2023 aligned. Customer data never leaves Indian regions.
- **Certifications**: ISO 27001:2022, SOC 2 Type II.
- **Standards alignment**: GDPR, DPDPA.
- **Encryption**: AES-256 at rest, TLS 1.3 in transit.
- **Isolation**: Per-tenant data segregation.
- **Audit trail**: Cryptographic, timestamped, immutable.
