FIS expands Anthropic partnership to strengthen cyber defenses

FIS is deploying Anthropic’s Mythos 5 through Project Glasswing to add an AI defensive layer to software that clears payments, moves money and runs core banking for thousands of institutions worldwide.

Project Glasswing is a controlled-access initiative run by Anthropic that gives organizations that build or maintain foundational software limited use of frontier AI models for defensive security work.

FIS has integrated Mythos 5 as an added layer within its security program to help detect and mitigate vulnerabilities in code and systems that support payment clearing and core banking. FIS stated the work under Glasswing is focused on defensive tasks under controlled conditions and is separate from commercial deployments of Anthropic agents the company may use for other purposes.

FIS operates systems that handle payment flows and core processing for financial institutions globally. The company participates in industry groups such as FS-ISAC and the Financial Services Sector Coordinating Council, engages with regulators and shares intelligence with peer organizations.

Under Project Glasswing, participants can apply advanced models to threat analysis, vulnerability discovery and code hardening while keeping controls on model access and use.

In a statement, FIS described the effort as part of a broader program of proactive defenses and sector cooperation. “We have integrated Mythos 5 into our defensive security processes under controlled conditions,” the company added.
