# Arthur Shield

Canonical: https://www.softwareadvice.ie/software/627538/Arthur-Shield

> Arthur Shield is a firewall solution for large language model (LLM) applications, designed for businesses of all sizes in regulated industries such as banking, healthcare, insurance, and financial services. It sits between an application and its LLM, validating prompts and responses in real time before they reach end users.

Core features include configurable detection rules for PII and sensitive data leakage, hallucinations, prompt injection attempts, toxic language, and other quality metrics. These rules apply across both input and output endpoints, giving security, compliance, and engineering teams auditable control over LLM behavior. The API-first design allows integration into existing LLM applications without major infrastructure changes.

Arthur Shield can be deployed as a cloud-based SaaS solution — with compatibility for AWS and Azure — or on-premises, making it suitable for organizations with strict data residency or infrastructure requirements. It is compatible with OpenAI and other leading LLMs.

Enterprises in regulated industries benefit from the ability to block value-misaligned responses, stop hallucinated content, and detect malicious prompt injection attempts, reducing reputational and operational risk. Support options include documentation and direct vendor support channels.
