KPMG Launches Cybersecurity Services Powered by Anthropic’s Claude Mythos

NEW YORK, Nov. 12, 2026 – KPMG LLP, the U.S. audit, tax and advisory firm, today announced new capabilities that use Claude Mythos, Anthropic's most capable AI model for cybersecurity. With KPMG's industry expertise and portfolio of frontier AI cybersecurity services, these capabilities help clients identify and prioritize software vulnerabilities, uncover complex risks and attack paths, prioritize remediation, identify data-security and breach risks, and strengthen cyber defenses.

As one of a select group of organizations, KPMG is also helping companies in Anthropic's Cyber Verification Program (CVP) deploy and apply Mythos within their own secure environments. KPMG's participation builds on its role with Anthropic’s early initiatives to put Claude Mythos in the hands of organizations securing critical software.

KPMG will initially embed Claude Mythos in four areas of its cybersecurity services:

• Application security and vulnerability management: Applying Claude Mythos to code-scanning assessments and reviews to identify critical vulnerabilities and attack chains across new and legacy codebases and prioritize remediation by business impact.
• Identity and access management: Combining Claude Mythos with identity telemetry, threat intelligence and application and system vulnerability data to uncover identity-enabled attack paths and excessive privileges across human, machine and agentic identities.
• Compromise and breach-risk management: Enhancing KPMG's incident-response and breach-pathway analysis to identify how connected security weaknesses could be exploited and inform targeted remediation.
• Data protection and security: Applying Claude Mythos to identify data-retention and security risks across structured and unstructured data.

“Powerful cyber AI has to work in the real world, where security, governance and accountability aren’t optional,” said Todd Lohr, Vice Chair and head of Client Technology & Innovation, KPMG LLP. “By bringing Claude Mythos into KPMG’s frontier AI cybersecurity services and combining it with our trusted approach and deep understanding of business risk, we’re helping clients move beyond experimentation and put these capabilities to work securely at enterprise scale.”

According to KPMG’s latest CEO Outlook report, 85 percent of CEOs anticipate cybercrime and cyber insecurity will affect their organization's prosperity over the next three years, ranking it above inflationary pressures, geopolitical concerns and the pace of technology change.

"Claude Mythos has changed the math on vulnerability discovery. Finding vulnerabilities is no longer the hard part. Deciding which ones matter most to the business and fixing them before attackers get there is. KPMG brings the cybersecurity, risk and industry expertise to turn those findings into fixes, in the right order," said Patrick Ryan, Anthropic Business Leader, KPMG LLP.

“Finding vulnerabilities is only as valuable as an organization's ability to act on what it finds. As KPMG works with clients, it can help those organizations defend against evolving threats while generating practical insights that can accelerate the safe and effective adoption of AI," said Jason Clinton, Deputy CISO, Anthropic.
