11.E. Please describe the main security measures your organization applies and indicate which are specific to particularly sensitive AI assets, where relevant.
Organization-wide measures. We operate a risk-based security program with periodic risk assessments reported to senior management, and hold ISO/IEC 27001:2022 and ISO/IEC 42001:2023 certifications alongside annual SOC 2 Type II examinations (reports via trust.anthropic.com). We maintain a threat-actor register and externally validated threat models spanning endpoint, supply-chain, physical, cloud, privilege-escalation and exfiltration vectors, and red-team AI-specific risks such as prompt injection. Baseline controls include multi-factor authentication and least-privilege, role-based access; managed-device access controls, endpoint detection and response, and application allowlisting on workstations; encryption at rest and in transit; network segmentation and data-loss controls; centralized logging with automated anomaly alerting; peer review and automated security analysis of code; continuous vulnerability scanning, risk-based remediation, annual external penetration testing, a public Responsible Disclosure Policy and bug bounties; layered physical security at our facilities and review of cloud service providers' independently audited data-center controls; and incident-response and business-continuity plans with escalation procedures for high-severity incidents, tested annually.
Measures specific to particularly sensitive AI assets. Our most sensitive AI assets are the weights of our most capable models; related training data and source code are restricted on a least-privilege, business-need basis. Weights additionally receive the ASL-3 protections our Responsible Scaling Policy (RSP) commits us to maintain or improve, designed to protect against most non-state attackers: multi-party, time-limited authorization using hardware security keys; device authorization limiting weight-system access to approved managed devices; egress bandwidth controls making large-scale exfiltration more time-consuming and detectable; cloud storage restrictions designed to prevent weights being written outside our security perimeter; network-source restrictions on privileged resources; additional review and commit-integrity requirements for critical repositories; and encryption, access logging and automated detection of unauthorized weight access or movement. Third-party partners hosting these models must implement equivalent security controls.
Personnel and insider risk (organization-wide). We apply pre-employment background checks where legally permissible; confidentiality agreements binding employees and contractor personnel before access is provisioned; security-awareness training at hire and annually, supplemented by AI-incident-response training for relevant staff; and a formal insider-risk program with internal monitoring, documented investigation and escalation procedures, and confidential and anonymous reporting channels, including RSP-noncompliance reporting with protection from retaliation.
Assurance. We publish RSP Risk Reports every three to six months and a Frontier Safety Roadmap of security goals; our Frontier Compliance Framework and "Activating ASL-3 Protections" report give more detail.
We run a dedicated insider-risk program under the security standards in our Responsible Scaling Policy: role-proportionate pre-employment verification, least-privilege access to model weights and sensitive assets with logging and monitoring, mandatory security training at hire and annually, and defined escalation channels to our Insider Risk and Security teams, including anonymous RSP noncompliance reporting. See our ASL-3 activation report and Trust Center.
