At CoreWeave, security and innovation are woven together. In AI, speed without trust isn’t progress; it’s risk at scale. Security is what creates the confidence to use sensitive data, deploy powerful models, and operate globally. The only way to move fast safely is to design it into everything from the start. We see that every day in how our customers build. Teams working in robotics train models that learn and operate safely alongside people. Financial innovators run large-scale simulations that reprice risk in seconds. Research labs compress years of discovery into weeks with generative and agentic AI systems. These breakthroughs only happen when the systems behind them can scale quickly and remain secure. When security is part of the architecture, it doesn’t slow innovation; it enables it. Our responsibility is to protect that foundation. We support the most advanced AI workloads in the world, and leading AI pioneers rely on us to keep them secure, performant, and compliant. That is why security is engineered into every layer of CoreWeave Cloud, from hardware through orchestration. It keeps protection and performance aligned so every new advance in AI can happen with speed, integrity, and reliability. Protecting the foundation Every great leap in AI begins with a solid foundation of trust at the hardware level. That foundation starts with a comprehensive threat model that identifies and prioritizes the risks to our production environment, guiding how we design, test, and harden our systems. We begin by understanding where the risks lie and building to defend against them. For example, each compute node on CoreWeave Cloud runs with NVIDIA BlueField data processing units (DPUs), specialized hardware that enforces tenant isolation and strengthens the security boundary between workloads. From firmware to container images, verification and hardening are becoming integral to how we bring new systems online across our 40+ and growing data centers. Data is encrypted in transit and at rest, with customer-managed keys supported where available and immutable logs providing complete traceability. We are expanding encryption enforcement through secure key management, hardened storage systems, and cryptographically verified access paths that extend from the control plane through runtime. Compliance is not an afterthought; it is a baseline requirement. It validates that our controls work as intended and that our security practices scale responsibly. CoreWeave has achieved SOC 2 Type II certification for Bare Metal and CoreWeave Kubernetes Service (CKS) and is expanding into broader international standards that strengthen information security, privacy, and cloud assurance. We are also looking at alignment with ISO/IEC 42001, the new global framework for responsible AI management, to ensure that our governance model evolves with the technology itself. Together these efforts create a unified foundation of trust that extends across CoreWeave Cloud, from hardware through orchestration and into the workloads our customers run every day. Identity is the connective tissue of trust. Federated IAM, SCIM automation, and workload federation using OIDC deliver real-time, fine-grained access control across clouds and clusters. Access updates in seconds and revocation is immediate. This multi-layer defense makes CoreWeave’s security posture both verifiable and extensible. It is how we prove readiness to enterprise and federal customers, and it is how we continue to raise the bar. We’re also developing a next generation framework for achieving full stack integrity across our infrastructure. It’s an example of how we continue to evolve security by design, validating every layer from firmware and boot through runtime using hardware based attestation and cryptographic trust. When complete, this system will extend verification across GPUs, DPUs, and CPUs, creating a continuous trust throughout the system operation. The people behind the protection Technology is only one part of the story. Our security team brings experience from across the industries operating clouds, national labs, and mission-critical systems. They apply their deep knowledge to the unique challenges of AI infrastructure. Our experts know what it means to operate at massive scale, under constant scrutiny, in an environment that never stands still. They are builders and defenders, engineers and investigators, working side by side to protect our customers’ most valuable work. This human expertise is what keeps our systems evolving. Every new capability we launch from hardware isolation to Automated User Provisioning (AUP) starts with their insights and is tested through their rigorous real-world validation. Security that scales and accelerates CoreWeave was purpose-built for AI from the start, not adapted from a general-purpose cloud. We have no legacy hypervisors, no inherited complexity, and no lock-in by design. This advantage allows us to build faster, integrate with greater precision, and deliver security engineered specifically for AI workloads. Where other AI clouds might focus on building capacity, CoreWeave focuses on building confidence. We believe security should empower, not restrict. Our multi-cloud architecture makes policies, identities, and compliance portable across environments. Customers can train in one region, deploy in another, or scale across clouds without rewriting policies or reconfiguring access. Security travels with them wherever they go. Our open model integrates natively with Okta, Entra, and S3 APIs, creating a seamless experience for enterprises that already have mature identity systems. Automated User Provisioning (AUP) for Slurm on Kubernetes (SUNK) extends that same automation to the cluster level, cutting onboarding from weeks to minutes. CoreWeave’s security ecosystem extends beyond our own platform. Our recent partnership with CrowdStrike combines CoreWeave’s high-performance AI Cloud with the CrowdStrike Falcon platform’s industry-leading protection to secure and accelerate the complex…
