How is FIS Enhancing Financial Security?
FIS is testing Mythos 5, Anthropic's most advanced frontier model, to scan and evaluate its own systems as part of the security initiative.
On July 16, 2026, FIS said it has joined Project Glasswing, Anthropic's controlled-access initiative that applies Mythos 5 to strengthen the security of software supporting critical infrastructure. The financial technology company is using the initiative to secure its own systems.
FIS said that as it 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 the global financial infrastructure. The company added that it applies the same security standard to its own infrastructure that it expects from the technology it delivers to clients.
Through Project Glasswing, FIS is using Mythos 5 as an additional layer within its security program, the company said.
Project Glasswing brings together organizations that build or maintain foundational software, and participants use Anthropic's most advanced AI models for defensive security work, according to the company.
FIS said the effort strengthens its commitment to proactive security and its role as a partner to the broader security community and financial services sector.
Broader Security Posture
Beyond Project Glasswing, the company said its overall security posture is shaped by active engagement with the Financial Services Information Sharing and Analysis Center (FS-ISAC) and the Financial Services Sector Coordinating Council. It also cited ongoing regulatory collaboration and industry intelligence-sharing.
FIS said the initiative is separate from its existing partnership to deploy Anthropic AI agents commercially. The company said both efforts reflect its disciplined approach to applying AI in financial systems, where security, reliability and trust are essential.
The announcement, however, did not include a timeline for expanding use of Mythos 5 beyond the current testing phase.
