Introducing Antares: Highly Efficient Open Weight AI Models for Vulnerability Localization
Today, Cisco is introducing Antares, a family of security small language models (SLMs) purpose-built for one of the hardest, most time-consuming and expensive problems in security: pinpointing where known vulnerabilities exist within a codebase.....
Cisco AI Defense: Built for the Way AI Is Actually Used
Enterprise AI lives in conversations — multilingual, multi-turn, and context-dependent. Security has to match that reality. Here is how Cisco AI Defense does.
Consistent security model deployment with FPR calibration
In our previous Dynamic AI Security blog and the underlying CAMLIS 2025 paper, we described a release platform built to move new protections into production without disrupting customer workflows. Such a platform is a requirement for security......
The Fundamentals of AI: Making AI practical
Training a large language model (LLM) can cost millions of dollars, and deploying one at scale can cost millions more. Despite this, the raw model straight out of training is often the wrong tool for any specific job. This is the gap that AI.......
Agents Securing Agents: The Agents Powering Policy Studio
At this year’s Cisco Live Las Vegas we introduced Policy Studio, an AI assistant in Cisco AI Defense that guides users through building custom policies for adaptive guardrails. The assistant interactively walks the user through the process..........
Fundamentals of AI: Inside the transformer
The transformer, introduced in a 2017 paper with the now-famous title "Attention Is All You Need," is the engine behind every major language model you have heard of. GPT, Claude, Gemini, Llama, Mistral. All transformer-based models. Understanding...
Inherited Circuits, Learned Semantics: How Security Fine-Tuning Can Create Hidden Evasion Risk
Fine-tuning is a process that lets us steer a general-purpose large language model toward a specific task by training it on targeted examples. In cybersecurity, this is often useful for problems like classifying phishing emails, suspicious URLs....
Securing AI Agents with Cisco AI Defense
AI agents are moving from demos into production fast — and every LLM call and external tool they invoke is a new attack surface. This post introduces Agent Runtime Protection in the Cisco AI Defense Python SDK: a one-line integration that brings....
