Strengthening LLMs with Proactive Security and Robustness Testing


Our Approach to Red Teaming for LLMs

At Welo Data, we provide comprehensive Red Teaming services that combine cutting-edge technology with deep expertise in AI security and ethics. Our multi-step approach is tailored to thoroughly evaluate your LLM’s defenses and ensure it meets the highest standards of reliability and security.

With our cutting-edge technology and deep expertise, we ensure your AI is equipped to handle complex, real-world challenges — making us the ideal partner to power your AI success.


Capabilities and Services

Our Red Teaming services go beyond conventional testing, ensuring your LLMs perform securely and ethically in real-world applications.

Adversarial Attack Simulations

We simulate a wide range of adversarial attacks, including prompt injections, model evasion, and data poisoning. These tests assess how well your LLM responds to malicious input designed to confuse or manipulate it. By identifying weaknesses, we help reinforce your model’s defenses against real-world threats.

Bias and Fairness Auditing

Our Red Team evaluates your LLM for hidden biases that could lead to unfair or inappropriate responses. We test the model’s outputs across diverse use cases and demographic groups to ensure equitable behavior and reduce the risk of biased or harmful outputs.

Robustness and Edge Case Testing

We challenge your model with out-of-distribution data, ambiguous queries, and adversarial examples to test its resilience. Our goal is to ensure your LLM performs consistently and accurately, even in challenging or unpredictable scenarios.

Security Vulnerability Assessments

Our team conducts in-depth analysis to identify security vulnerabilities such as data leakage, model inversion, or unauthorized access. We implement solutions that safeguard your LLM’s data and architecture, ensuring it meets stringent security standards.

Ethical and Regulatory Compliance

Red Teaming also involves assessing your LLM against ethical guidelines and regulatory frameworks, such as GDPR or AI-specific guidelines.


Common questions. Straight answers.

Red teaming is structured adversarial testing that simulates attacks against a language model, such as prompt injections, model evasion, and data poisoning, to uncover vulnerabilities before real users or bad actors do.

Yes, and this is where most vulnerabilities go undetected. Welo Data’s own research across 10 LLMs and 79 languages found 4-5x higher unsafe completion rates in low-resource languages compared to English, meaning English-only red teaming misses the majority of a model’s real safety gaps.

Four categories: adversarial robustness (how the model handles malicious or manipulative input), bias and fairness gaps across demographic groups, security vulnerabilities such as data leakage or model inversion, and compliance gaps against frameworks like GDPR or other AI-specific regulations.

Standard QA checks whether a model behaves correctly under expected conditions. Red teaming deliberately tries to break it: out-of-distribution inputs, ambiguous queries, and adversarial examples designed to surface failure modes that normal testing would never encounter.
