As autonomous agents make the digital world more dangerous, Rubrik, the Security and AI Operations Company, unveils Rubrik Code Guardian, a custom Claude Mythos 5 harness that red-teams customers' code based on an air-gapped copy of their repository. The new service uncovers and prioritizes the multi-step vulnerability chains an attacker would actually exploit, validates each for exploitability, and turns confirmed critical issues into tracked remediation.
Rubrik unveils Rubrik Code Guardian with Claude Mythos 5
Red-teams customer code based on air-gapped copy of repository
Uncovers and prioritizes multi-step vulnerability chains
Validates each for exploitability before surfacing findings
Pushes confirmed issues into Jira or GitHub with remediation guidance
Currently accepting select design partners for private preview
"Rubrik is one of the partners we are working with to put Claude Mythos 5's cyber capabilities in defenders' hands, so they can find and validate attack paths before attackers do," said Michael Moore, Cybersecurity lead at Anthropic. "Rubrik will use the model to test code faster and at far greater scale, and to bring cyber resilience up to the speed of AI."
Rubrik Code Guardian makes critical enterprise systems more resilient to even the most advanced frontier AI-powered attacks. The product embeds and harnesses Anthropic's Claude Mythos 5 into a service that operates directly on air-gapped copies of source code, enabling frontier model level vulnerability analysis while minimizing risk and impact on production environments.
"Frontier models are advancing at a fast pace. In the wrong hands, these models can be used to discover, chain, and exploit vulnerabilities at machine speed," said Arvind Nithrakashyap, Co-Founder and Chief Technology Officer at Rubrik. "To move just as fast, we are using frontier AI to scale vulnerability detection faster than our traditional code scanning tools. We took Anthropic's powerful model and built a Rubrik software harness to test on our code. We are using that experience and success now to give customers access to the harness, with a secure, isolated environment, which means we can run analysis of their code away from live repository and production systems."
Rubrik Code Guardian proactively secures the core intellectual property that powers modern businesses:
Red-Team Customer Code, Safely: Runs Claude Mythos 5 through Rubrik's custom security harness against a secure clone of the immutable, air-gapped copy never against the live repository or production environment.
Attack Chains, Not Alerts: Reasons across files, services, authentication patterns, and cloud boundaries to surface previously undetectable vulnerabilities, even "chained vulnerabilities" that advanced AI attacks now exploit.
Validated Findings, Prioritized by Business Criticality: Validates attack chains for real exploitability before surfacing them and prioritizes findings by exploitability, blast radius, and business criticality.
Accelerated Remediation: Pushes confirmed critical issues into developer workflows through Jira or GitHub issues with file-level remediation guidance.
Built-In Code Resilience: Maintains recovery workflows so organizations can restore a known-good codebase if a security event or bad build occurs.
