About Prompt Security
Prompt Security is a cutting-edge startup specializing in safeguarding organizations from the risks associated with Generative AI (GenAI). The company operates in the cybersecurity market, focusing on protecting businesses that use or develop applications powered by Large Language Models (LLMs).

Prompt Security serves a diverse range of clients, including enterprises, tech companies, and any organization integrating GenAI into their operations. The platform offers real-time threat detection and mitigation, ensuring that sensitive data remains secure and that AI applications behave predictably and safely. By providing instant visibility into all GenAI activities within an organization, Prompt Security helps clients maintain productivity while minimizing risks.
The business model of Prompt Security is based on a subscription service. Clients pay a recurring fee to access the platform, which includes continuous monitoring, threat detection, and mitigation services. This model ensures a steady revenue stream while providing clients with ongoing protection and updates.
Prompt Security makes money by offering tiered subscription plans, which vary based on the level of protection and features required by the client. Additional revenue streams may include consulting services and customized security solutions for larger enterprises with unique needs.
In summary, Prompt Security is a vital player in the cybersecurity market, offering a user-friendly platform that empowers organizations to safely embrace GenAI technology. By addressing key concerns such as data leaks, offensive content, and brand reputation, Prompt Security ensures that businesses can leverage AI advancements without compromising security.
