CloudHSM vs. on-prem HSM: Which one fits your security strategy?
Every organization that handles sensitive data needs to protect its encryption keys. This is the foundation of digital trust. Traditionally, this meant installing and maintaining physical Hardware Security Modules (HSMs) in secure data centers.
But there’s another way. With CloudHSM, the same trusted protection moves to the cloud – without the need for physical hardware, long deployment cycles, or ongoing maintenance.
On-prem HSM: Full control, full responsibility
Running an HSM on-premises gives organizations complete ownership and control over their security environment. The hardware is physically in your hands: you decide who can access it, where it’s installed, and how it’s connected.
This approach is often required in highly regulated sectors such as finance or government, where regulations like FIPS and compliance frameworks demand physical custody of cryptographic devices and air-gapped infrastructure to maintain full control over cryptographic key storage.
However, full control also comes with full responsibility. Organizations must manage every aspect of the lifecycle – from installation, and firmware updates to continuous monitoring and secure backups.
Scaling can be slow and costly, as each new environment requires new hardware, additional rack space, and specialized expertise to operate the devices securely.
In short, on-prem HSMs deliver the highest level of control and compliance — but at the cost of capital investment, operational effort, and time.
CloudHSM: Security that adapts to you
Securosys CloudHSM offers the same level of certified hardware protection — but as a fully managed service. Instead of purchasing and operating your own HSMs, you access them securely through the cloud.
With CloudHSM you benefit from:
- No installation or Capital Expenditures (CAPEX) – start in days, not months.
- Predictable, pay-as-you-go costs that grow with your needs.
- Automatic maintenance and backups, handled for you by our team of experts.
- Global clusters (clusters in Switzerland, Germany, Singapore and USA) ensuring availability, low latency, and redundancy.
- Safe testing environment to test Securosys CloudHSM in your own architecture.
You keep end-to-end control of your keys — only you can generate, use, or delete them — while Securosys ensures the secure operation of the underlying HSMs.
For organizations without the internal resources to deploy and maintain hardware, CloudHSM provides an easy path to enterprise-grade encryption and compliance-ready key management, accessible anywhere in the world. This solution is also particularly attractive for businesses looking to integrate with multi-cloud and hybrid environments.
Making the right choice
If your organization needs:
- Direct hardware ownership
- Physical control over access and networks
- Compliance that explicitly requires in-house devices
then, an on-premises HSM remains the right fit. Check out our Primus HSMs to find the one fitting your business security infrastructure.
If, however, you need:
- Fast deployment and scalability
- No hardware investment or maintenance burden
- Predictable operational costs
- The ability to focus on your core applications rather than infrastructure
then, CloudHSM delivers the same strong security with greater agility and simplicity. Learn more about our CloudHSM offer.
