About AIShield

AIShield provides security for AI/ML models and GenAI applications, addressing vulnerabilities like prompt injections, jailbreaks and data leaks. AIShield is a full-stack security product, based on technical research over four years and over 45 patents, that defends AI-based application workloads across on-prem, cloud and edge environments. AISpectra is designed to keep AI/ML models and LLM applications secure throughout development. AISpectra covers AI models and LLM applications at every stage, from development to testing and training. AIShield Guardian is designed to provide real-time security to live AI/ML and Generative AI applications.[2][3][4][6][8][10]

AIShield states that traditional security measures fail to address AI-specific risks like adversarial attacks and data leakage. AIShield states that after deployment, the lack of an AI Firewall and real-time monitoring leaves AI models and LLM applications vulnerable to threats including prompt injection and data leakages. Guardian offers protection for deployments of LLM-powered chatbots, algorithmic trading models and AI-driven automation systems.[4]
