Securing LLM apps & AI agents
LLM apps and agents open new attack paths, from prompt injection and data leakage to tampered model files. This shortlist ranks AI security platforms by protection depth: blocking attacks at runtime first, then automated red teaming, model supply-chain scanning, and prompt-injection detection. Pricing is almost always quote-based, so also weigh deployment options, added latency, and which model providers are covered.
