How to Choose a AI Security Tool
Key criteria to evaluate when comparing AI Security solutions:
About Prompt Security
Prompt Security protects LLM applications from injection attacks and jailbreaking. Real-time threat detection for prompts.
About Cisco (Robust Intelligence)
Robust Intelligence was founded in 2019 by Yaron Singer, a former tenured Harvard professor, and was acquired by Cisco for USD 400 million in October 2024. The company pioneered the AI security category with cutting-edge research and product innovation, including algorithmic red teaming and the industry's first AI Firewall. Robust Intelligence's platform mitigates risks like prompt injection, data poisoning, jailbreaking, and unintentional model outcomes. Now integrated into Cisco's security portfolio as part of Cisco AI Defense, Robust Intelligence's capabilities protect AI applications, APIs, models, and agents with comprehensive security measures. The acquisition positions Cisco as a leader in AI-native security, though integration challenges and technology maturity questions remain as the company scales its relatively young but promising technology.
