Fort Lauderdale, Florida — June 11, 2026 —

CSG, which owns leading software brands such as Citrix, TIBCO, and InfoScale and provides mission-critical platforms used by businesses worldwide for their daily operations, announced its participation in Anthropic’s “Project Glasswing,” an initiative aimed at protecting the world’s most critical software infrastructure.

CSG’s products are located at the edge of customer environments and handle customers’ most sensitive data. As a result, the company’s security is a top priority for the businesses and organizations that rely on them.The company already operates an AI-driven product security program, incorporating AI-powered security reviews into the software development lifecycle rather than relying on traditional periodic audits.

As part of the recently announced expansion of Project Glasswing, CSG has gained access to Anthropic’s “Claude Mythos Preview.”With the introduction of Mythos, the company expects to further evolve its existing security program and build a more robust defense system by rapidly identifying vulnerabilities, refining vulnerability triage and remediation plans, detecting complex attack vectors often missed by traditional security testing, and responding swiftly to open-source threats.Anthropic’s Claude Mythos Preview has been implemented across all of CSG’s business units, with the company managing its deployment, security architecture, and usage governance.

Tom Kraus, CEO of CSG, stated:

“Participating in Project Glasswing further advances our AI-driven efforts to ensure the security of our customers’ applications and data, and further accelerates our already mature program. Our platform is used in highly complex, strategic, and sensitive environments such as national security, financial services, and healthcare.We expect that access to this program will enable us to detect vulnerabilities at scale and at a faster pace than ever before, and address them before they can be exploited. We look forward to collaborating with Anthropic and other participants in Project Glasswing to build the next generation of cyber defenses.”
