A real-time AI security firewall that cleans incoming prompts and stops data leaks.
PromptGuard is an AI security tool that helps businesses protect their AI applications from cyber threats, malicious prompts, and sensitive data leaks. It works as a security layer between an application and its large language model (LLM), checking requests before they reach the model. This helps prevent prompt injection attacks, jailbreak attempts, personal information exposure, and unauthorized data access.
The platform uses machine learning, detection patterns, and multiple security layers to identify suspicious activity. It can also detect and redact personally identifiable information (PII), API keys, and other confidential details. Users can monitor security events, review audit logs, and customize protection policies through its dashboard.
PromptGuard supports major AI providers, including OpenAI, Anthropic, Google Gemini, and Amazon Bedrock. Businesses can deploy it through its managed cloud service or within their own infrastructure. With its focus on AI security, PromptGuard is useful for developers, startups, and enterprises building AI-powered applications that require stronger data protection and threat prevention.
