JACKSONVILLE, Fla.--(BUSINESS WIRE)--

FIS® , a global financial technology leader, is using Mythos 5 through Project Glasswing, Anthropic’s controlled-access initiative that applies frontier AI to help strengthen the security of software supporting critical infrastructure, to secure its own systems.

FIS operates systems that clear payments, move money and run core banking for thousands of institutions worldwide. Protecting that code is critical to the stability of global financial infrastructure. At that scale, FIS applies the same standard to its own infrastructure security that it expects from the technology it delivers to clients.

Through Project Glasswing, FIS is putting Mythos 5, Anthropic’s most advanced frontier model, to work as an additional layer within its security program. Project Glasswing brings together organizations that build or maintain foundational software. Participants use Anthropic’s most advanced AI models for defensive security work. This reinforces FIS’ commitment to proactive security and being a supportive partner to the broader security community and financial services sector.

In addition to FIS’ participation in Project Glasswing, its overall security posture is shaped by active engagement with FS-ISAC and the Financial Services Sector Coordinating Council, ongoing regulatory collaboration and industry intelligence-sharing. The initiative is separate from FIS’ commercial deployment of Anthropic AI agents but reflects the same disciplined approach to applying advanced AI in financial systems where security, reliability and trust are essential.
