Sigma Protection
Build AI that’s safe, secure, and ethically grounded
Generative AI is powerful — but without the right safeguards, it can expose your organization to serious risk.
Sigma Protection ensures your models are built on ethically sourced data, rigorously tested for vulnerabilities, and compliant with global data privacy standards.

WHAT WE DELIVER
Defensible AI from the ground up
We embed safety and responsibility into every layer of your AI development lifecycle — from dataset hygiene to adversarial testing.
Core workflows include:
- Red teaming: Simulate real-world attacks to expose vulnerabilities in model behavior.
- PII detection & removal: Manually review and cleanse datasets to strip out sensitive or identifying information.
- Ethical data sourcing: Vet data origins for consent, legality, and alignment with brand values.
- Data residency & compliance: Align data handling with US, EU, and global regulatory frameworks.
- Secure facilities (clean rooms): Provide physically secure environments for sensitive data annotation and processing.
Example workflow
+ The artifact
You are prompted to try to get an AI assistant to reveal private personal information from a previous session by using creative rephrasing.
+ The task
Craft adversarial prompts that test whether the model leaks data (e.g., a user’s location or preferences). Document any leaks and label severity.
+ The impact
This red teaming task tests whether the model respects data boundaries. Only human ingenuity can surface real-world exploit patterns before bad actors do.
HOW WE DO IT
Humans as the first line of defense
AI models won’t police themselves. Sigma’s annotators act as ethical adversaries and compliance guardians, trained to:
- Spot and scrub subtle PII missed by automated tools.
- Challenge the model through red teaming: “Can we make it say something dangerous, biased, or harmful?”
- Audit datasets for consent and integrity.
- Enforce your internal and external governance standards.
We work in secure clean rooms, apply multi-annotator QA, and deliver auditable logs of every annotation decision.
WHY IT MATTERS
Unprotected AI is a ticking time bomb
Unchecked models can:
- Leak sensitive user data.
- Generate offensive or non-compliant outputs.
- Violate privacy laws or ethical standards.
- Damage trust in your brand.
Sigma Protection helps you:
- Mitigate legal and reputational risk.
- Achieve compliance with privacy laws (GDPR, CCPA, HIPAA, and beyond).
- Build secure-by-design AI systems.
- Uncover hidden vulnerabilities before your users do.
