Microsoft has revealed more details about its custom-built security chip, Azure Integrated HSM, which is now deployed across every Azure server to help combat the growing global cybercrime threat, estimated at $10.2 trillion annually.
Tackling Cybercrime at Scale
The disclosure came during Microsoft’s presentation at the Hot Chips 2025 conference, where the company highlighted both the scale of cybercrime and its efforts to strengthen cloud security. Microsoft cited figures showing the global cost of cybercrime now stands at $10.2 trillion—placing it behind only the United States and China in terms of economic scale, and larger than the economies of Germany and Japan.
According to the company, such widespread threats require significant architectural and operational shifts in how cloud infrastructure is designed and managed. With Azure spanning more than 70 regions and 400 data centers, supported by 275,000 miles of fiber and 190 network points of presence, Microsoft is embedding new security measures directly into the hardware layer.
Azure Integrated HSM: Security at the Chip Level
At the center of this strategy is the Azure Integrated HSM (Hardware Security Module), a custom-built ASIC (application-specific integrated circuit). First announced in late 2024, the chip has now been rolled out across Microsoft’s global Azure infrastructure.
The Azure Integrated HSM is designed to meet FIPS 140-3 Level 3 requirements, which demand tamper resistance and local cryptographic key protection. By embedding the chip into each individual server, Microsoft has shifted away from a centralized HSM model.
This local integration reduces latency, as cryptographic operations no longer need to be routed through a cluster. Functions such as AES (Advanced Encryption Standard), PKE (Public Key Encryption), and intrusion detection can now be handled directly within the server hardware.
Balancing Performance and Security
Microsoft acknowledged that building a Azure Integrated HSM required trade-offs. Rather than scaling security modules at the cluster level, the company needed to size them appropriately for each server. The result, according to Microsoft, is a balance between performance, efficiency, and resilience—delivering security protections without creating bottlenecks for large-scale cloud workloads.
The move is also part of Microsoft’s broader “Secure by Design” architecture, which falls under its Secure Future Initiative. The initiative emphasizes embedding security features at the hardware, software, and operational layers of Azure.
Secure Future Initiative Enhancements
Alongside the Azure Integrated HSM, Microsoft highlighted several other security innovations within its cloud infrastructure:
- Azure Boost – Offloads control plane services to a dedicated controller, isolating them from customer workloads.
- Datacenter Secure Control Module – Integrates Hydra BMC (Baseboard Management Controller) and enforces a silicon root of trust across management interfaces.
- Confidential Computing – Expands the use of trusted execution environments (TEEs) to protect workloads in multi-tenant environments, ensuring data security even while in use.
- Caliptra 2.0 – A joint effort with AMD, Google, and Nvidia, anchoring security in silicon with the latest support for post-quantum cryptography through the Adams Bridge project.
These measures reflect Microsoft’s goal of building layered defenses that begin at the silicon level and extend across software and operational practices.
A Hardware-First Approach to Cloud Security
With cloud adoption accelerating across industries, the hardware-level protections offered by Azure Integrated HSM represent a significant development in securing large-scale distributed infrastructure. By embedding cryptographic functions directly into each server, Microsoft aims to reduce vulnerabilities while maintaining speed and scalability.
As cybercrime continues to grow into a trillion-dollar challenge, cloud providers are under pressure to evolve their defenses. Microsoft’s latest announcement underscores its commitment to tackling these risks by combining custom hardware, advanced cryptography, and operational security measures across its global Azure platform.
