About

PromptArmor is a cybersecurity company specializing in protecting AI systems and large language model (LLM) applications from adversarial attacks — particularly prompt injection, jailbreaking, and data exfiltration through AI interfaces. As enterprises deploy AI assistants, chatbots, and autonomous agents at scale, new attack surfaces emerge: malicious users can craft carefully worded inputs that bypass AI safety guardrails, extract confidential information from AI systems, or manipulate AI agents into taking unintended actions. PromptArmor develops detection and mitigation tools for these AI-specific vulnerabilities.
