About WalledAI

WalledAI is an enterprise AI governance platform that provides safeguards for the safe and compliant deployment of large language models (LLMs) within organizations, including healthcare settings. The company’s solutions are designed to address critical issues such as data privacy, problematic AI hallucinations, and the overall reliability of AI systems. For physicians, this means the ability to leverage AI for tasks like clinical documentation, diagnostic research, treatment planning, and patient communication, while WalledAI works to mask patient identifiers and validate medical outputs against approved clinical databases to prevent dangerous inaccuracies.

The platform offers customizable solutions to ensure compliance with AI laws and regulations, supporting both collective and standalone deployments to suit various enterprise setups. Key features include advanced analytics, robust security, and customizable controls, enabling enterprises to build safer and more efficient AI systems. In healthcare, WalledAI’s architecture aims to ensure that no Protected Health Information (PHI) reaches the LLM, with patient names, medical record numbers, diagnoses, and treatment details masked before AI processing. It also provides complete audit trails to satisfy HIPAA’s access logging requirements. WalledAI also detects unsanctioned AI usage, enforces policy in real-time, and logs attempts to prevent ‘shadow AI’ from exposing sensitive data.

What Physicians Need to Know

AI Governance & LLM Security

WalledAI provides a comprehensive enterprise AI governance platform that sits between users, applications, and any LLM (e.g., GPT-4, Claude, Gemini, Llama, Mistral, Copilot). It offers a single control plane for masking, monitoring, and auditing every AI interaction. Key features include real-time content filtering, prompt injection defense with 99.7% accuracy, detection and blocking of adversarial prompts, and filtering of toxic or off-topic content. They also offer 'Walled Correct' to validate AI responses against ground truth, with configurable confidence thresholds and automatic escalation for human review.

Data Privacy & Redaction

WalledAI specializes in protecting sensitive data by masking PII, confidential data, and trade secrets across various modalities (text, images, documents, code, audio) *before* it reaches any LLM. The data is unmasked seamlessly upon return to the user. Their 'Walled Redact' solution automatically detects and replaces sensitive information with synthetic tokens, ensuring zero PII reaches third-party AI.

Prompt Injection Defense

WalledAI's 'Walled Protect' offers multi-layered defense against prompt injections, jailbreaks, and adversarial attacks in real-time with high accuracy. This includes blocking direct and indirect prompt injections, which can manipulate LLM behavior or extract training data.

Hallucination Detection

WalledAI addresses hallucination detection through 'Walled Correct,' which validates every AI response against trusted sources and approved clinical guidelines. It provides confidence scores and flags low-certainty AI suggestions for physician review.

Regulatory Compliance

WalledAI ships pre-configured evidence mapping across major regulatory regimes, including the EU, US, UK, Singapore, and India, to facilitate audit-ready reporting. For healthcare, they ensure compliance with HIPAA, FDA 21 CFR Part 11, and GDPR (Healthcare), with full PHI detection across all 18 identifier categories and BAA-ready deployment.

Shadow AI Detection

WalledAI detects unsanctioned AI usage at the browser and network layer, enforcing AI usage policies in real-time and logging every attempt. This helps organizations identify and govern the use of consumer chatbots, browser extensions, and unauthorized copilots that employees might use.

Enterprise AI & Deployment

WalledAI is built for enterprise-scale AI adoption, offering sovereign, on-premise, and air-gapped deployment options. This ensures data residency and zero data egress, making it suitable for highly regulated industries like financial services, healthcare, and government. They provide granular, policy-driven access controls (Enterprise RBAC) to manage who can use which LLMs and what data they can share.

Physician Tip

For physicians, WalledAI offers a critical layer of security and compliance for using AI in clinical practice. It enables safe AI adoption by masking Protected Health Information (PHI) before it reaches any LLM, ensuring HIPAA compliance. Clinicians can use AI for tasks like clinical documentation, diagnostic research, and treatment planning, with WalledAI validating medical outputs against approved clinical databases to prevent dangerous hallucinations. The platform provides complete audit trails for every AI interaction, satisfying HIPAA's access logging requirements and supporting regulatory oversight. This allows healthcare organizations to leverage AI for productivity gains without compromising patient privacy or regulatory compliance.

WalledAI's platform is designed as an infrastructure layer that sits between users/applications and any LLM (GPT-4, Claude, Gemini, Llama, Mistral, Copilot), making it model-agnostic. This allows for flexible integration with various AI tools and models without requiring per-tool security reviews. They also emphasize that their solution can be deployed on-premises, in private clouds (AWS, Azure, GCP within your VPC), or air-gapped environments, ensuring compatibility with existing IT infrastructures.
