Claude: enterprise security configurations and deployment controls explained

As organizations adopt Claude for sensitive workloads — from software development to regulated data processing — enterprise-grade security has become a central priority. Anthropic has built a comprehensive security stack for Claude Enterprise and Claude API users, combining identity controls, network isolation, zero-data-retention options, and SOC 2-aligned audit capabilities.

As of August-September 2025, Claude provides enterprises with advanced tools to secure deployments, manage compliance obligations, and protect sensitive data at scale.

Single Sign-On (SSO) strengthens identity management.

Claude Enterprise supports SAML 2.0 and OIDC-based SSO, enabling organizations to centralize authentication and enforce stronger identity governance.

• Supported protocols: SAML 2.0 and OIDC, fully documented in the Enterprise SSO setup guide (updated 13 August 2025).

• Capabilities included:

  • Domain capture for automated workspace enrollment.

  • Just-in-Time (JIT) provisioning tied to identity provider (IdP) authentication.

  • Integration with popular IdPs such as Okta, Azure AD, and Ping Identity.

• Setup requirements:

  • The Primary Owner must verify the organization’s domain via DNS TXT validation.

  • IdP metadata must be uploaded to the Claude Admin Console before enabling SSO.

These controls allow enterprises to streamline onboarding, enforce MFA policies, and restrict unauthorized access to Claude environments.

Role-based access control (RBAC) enhances permissions management.

Role-based access control (RBAC) provides fine-grained visibility and delegation for enterprise deployments.

• Available roles:

  • Primary Owner — full organization control; only one per domain.

  • Admin — manages workspace members, security policies, and API configurations.

  • Member — standard usage permissions without configuration rights.

• Upcoming expansion: RBAC will extend to Claude Team Pro in Q4 2025, bringing structured permissioning to smaller teams.

With RBAC, organizations can segregate responsibilities and minimize insider risk by ensuring users access only the features they need.

Exportable audit logs provide visibility into usage.

Claude Enterprise includes audit logging capabilities aligned with SOC 2 Type II reporting, allowing admins to track model usage and data flows across the organization.

• What’s captured:

  • User sign-ins, session starts, and API token usage.

  • Model calls and associated metadata (without storing full prompt content if ZDR is active).

  • File upload, download, and deletion events.

• Export capabilities:

  • Audit logs are retained for 30 days by default in the Claude Admin Console.

  • Admins can export JSON or CSV formats or push logs directly into SIEM platforms such as Splunk, Datadog, or Elastic.

Audit trails allow enterprises to monitor compliance, investigate anomalies, and integrate security analytics into existing monitoring systems.

Zero-Data-Retention (ZDR) ensures full log isolation.

For organizations handling regulated or sensitive data, Claude offers an optional Zero-Data-Retention (ZDR) addendum that eliminates stored records entirely.

• How ZDR works:

  • Requests are scanned in real-time for abuse detection and immediately discarded.

  • No prompts, outputs, or metadata are persisted on Anthropic’s systems.

• Scope of availability:

  • Available for Enterprise API traffic routed through a commercial org key.

  • The Claude web UI and beta features are excluded unless explicitly added to the signed contract.

• Contract requirements:

  • ZDR must be activated via an executed security addendum.

  • Often paired with other compliance frameworks like HIPAA, GDPR, or PCI.

ZDR endpoints are essential for enterprises in healthcare, financial services, and regulated cloud environments that require strict non-persistence guarantees.

Network isolation via AWS Bedrock and Private Service Connect.

Claude deployments can be fully isolated using AWS Bedrock or Google Vertex AI with Private Service Connect (PSC).

• Functionality:

  • Routes Claude API traffic entirely within a customer-controlled Virtual Private Cloud (VPC).

  • Ensures zero egress from enterprise networks while maintaining low-latency model calls.

• Deployment options:

  • AWS Bedrock integration: Supports VPC-scoped Claude access for private workloads.

  • Google Vertex AI integration: PSC endpoints became GA in April 2025 for Claude-hosted tenants.

• Use cases:

  • Banking, healthcare, and government agencies needing strict network sovereignty and geo-fencing policies.

These features make Claude deployable in high-security enterprise infrastructures where regulatory mandates require traffic isolation.

Encryption standards meet enterprise-grade security.

Claude applies strong encryption controls by default across its infrastructure.

• In transit: Uses TLS 1.2+ for all network requests, ensuring secure communication.

• At rest: Enforces AES-256 encryption for stored logs, model outputs, and files.

• Key management roadmap:

  • Today: KMS-backed provider-managed keys on AWS and Google Vertex AI.

  • Coming in H1 2026: Support for Bring Your Own Key (BYOK) configurations, allowing customers to manage encryption keys directly.

This dual-layer approach ensures compliance with ISO 27001, SOC 2, and HIPAA encryption standards.

SOC 2 Type II certification and attestations.

Anthropic has completed an independent SOC 2 Type II audit of Claude’s infrastructure, validating its security, availability, and confidentiality commitments.

• Availability:

  • SOC 3 summary report is publicly accessible via Anthropic’s Trust Portal.

  • SOC 2 detailed report is available under NDA for Enterprise customers.

• Scope covered:

  • Claude’s APIs, web applications, audit logging framework, and ZDR endpoints.

These attestations assure organizations that Claude meets recognized benchmarks for secure enterprise deployment.

Security automation in Claude Code.

For software engineering teams, Claude Code now integrates security into CI/CD pipelines through its GitHub Action:

• Launched: 6 August 2025.

• Features:

  • Scans pull requests for known vulnerabilities and insecure patterns.

  • Posts inline suggestions to remediate security issues automatically.

• Availability:

  • Supported for Claude Code Team and Enterprise accounts.

  • Requires organization-scoped repository tokens and workspace-level API keys.

This integration extends DevSecOps practices directly into code review workflows.

Advanced safety classifiers enhance threat detection.

Anthropic has introduced safety classifiers built in partnership with the U.S. National Nuclear Security Administration (NNSA) to detect and flag high-risk prompts.

• Supported detection categories:

  • Nuclear-related instructions.

  • Biological and chemical weapon-related queries.

• Enterprise webhook alerts:

  • Enterprise customers can optionally receive webhook alerts when such prompts are detected.

  • Note: Webhook integration is currently in private beta and will expand in Q1 2026.

This layer of proactive monitoring strengthens content risk controls without replacing dedicated enterprise data-loss prevention (DLP) systems.
