Chang and Varakantam shared a quote from Michael Moore, cybersecurity lead at Anthropic: “Enterprises are increasingly building AI agents into their core operations and want to test those agents thoroughly before putting them into production. By bringing Claude Mythos to Cisco AI Defense, Cisco can help security teams red team their agents with advanced reasoning that plans tests and generates attack ideas for each system.”
“The [Mythos] model sits inside AI Defense with a fixed job, a registered target, and objectives defined by the human user. While customers do not get an open interface to Claude Mythos, they get to inform the target and objective, and our agentic red teaming framework conducts the engagement within those bounds. We regard this as an early instance of a broader shift, in which the frontier capabilities most relevant to security are made available to defenders under verified, controlled access rather than withheld from everyone,” Chang and Varakantam wrote.
“Cisco designed this deployment to operate against only the target a customer has registered and is authorized to test; it runs with a fixed job and human-defined objectives, has no open interface a customer could use to prompt it freely, and its activity is confined to the authorized target rather than the wider internet. Every action it takes is attributable to a named operator and recorded for audit. These product-level controls sit alongside the program-level safeguards and monitoring, so containment does not rest on any single layer,” Chang and Varakantam wrote.
