The demo covers a finance app with an LLM chatbot deployed on a hybrid cloud/on-prem environment. AI Defense uses algorithmic red teaming to launch thousands of automated attacks against the model, finding that ~69% were blocked natively, then applies guardrails to close the gap. The demo also covers Cisco Secure Workload for microsegmentation and Kubernetes visibility, CVE-based IPS rule synchronization, and the Encrypted Visibility Engine which uses a recurrent neural network to classify TLS flow intent without decryption, including catching zero-day threats via Snort ML. ## Full article daily.dev links to this article rather than hosting it.
