LLM data protection for your industry
Obfusca ships with industry-specific protection profiles, combining pattern detection, semantic AI rules, and enforcement policies, so you can start protecting sensitive data in minutes, not weeks.
Technology
Protect source code and infrastructure secrets
Developers routinely paste code snippets, configuration files, and debug output into AI tools. Obfusca catches API keys, AWS credentials, GitHub tokens, private keys, and internal service URLs before they leave the browser, plus semantic detection that catches secrets described in natural language.
Key detection patterns
- API Key (sk- prefix): blocks OpenAI, Anthropic, and Stripe keys
- AWS Access Key ID and Secret Access Key
- GitHub tokens (ghp_ and github_pat_ formats)
- Private Key (PEM): RSA, EC, DSA, OPENSSH, and PGP private keys
- Bearer tokens in authorization headers
Semantic detection rules
AI-powered detection that catches what regex can't
- Detects proprietary technology and unreleased product names
- Catches internal architecture and infrastructure details
- Flags source code with embedded credentials
- Identifies competitive strategy and roadmap information
