Cisco and IBM to add Anthropic's Mythos model to security products

Mythos is an Anthropic model so good at finding software flaws that Anthropic first rationed it to vetted organizations. Cisco's AI Defense, which attacks a customer's AI models, agents and apps to find weak spots, can now call Mythos under existing licenses at no added cost. IBM is adding it to Concert to find flaws traditional scanners miss and to draft fixes. Customers get the results, never the model. It works like a locksmith who tests your doors but keeps his picks. Why widen access to a tool that helps attackers? Because buyers queued and the vendors hold the gate. The gate is not airtight: Anthropic says it built its strongest-ever protections against distillation, meaning cloning. For a bank on Cisco, a stronger test costs nothing. Attackers will not wait for a license.
