The vault that keeps your organisation's most critical cryptographic keys out of reach — even from you. Tamper-resistant hardware security for banks, government departments, and enterprises.
Think of a Hardware Security Module as a bank vault built specifically for digital keys. Instead of storing an encryption or signing key in a software file — where it can be copied, leaked, or stolen — an HSM generates the key inside a tamper-resistant hardware box and never lets it leave in a usable form.
Every signing or encryption operation happens inside the device; the application outside only ever sends a request and receives a result, never the key itself. This is why HSMs sit at the core of digital security for banks, government departments, large enterprises, and manufacturers — anywhere a compromised key could put transactions, data, or operations at risk.
Care4Sign helps organisations across these sectors select, deploy, and integrate the right HSM for their digital signing and encryption needs.
A dedicated appliance on your network, shared across applications and servers. Best for data centres, CA infrastructure, and banks needing centralised key services.
Best For EnterprisesA card installed directly inside a server. Ideal for single high-throughput applications needing the lowest possible latency.
Lowest LatencyHSM capacity delivered as a managed service, billed like any cloud resource. For organisations that want HSM-grade security without owning hardware.
No Hardware NeededThe global benchmark for tamper-resistant hardware. Level 3 means the device physically detects and reacts to tampering — wiping keys rather than just resisting intrusion.
An independent, internationally recognised evaluation of the device's security design and implementation — accepted across government and enterprise procurement.
The specific certification required for payment card processing, covering PIN handling and card-transaction key operations — mandatory for banks and payment gateways.
A formal, witnessed process used to generate and back up an organisation's most sensitive keys — so no single person ever has unsupervised access.
Multiple HSMs work as a group — if one fails or needs maintenance, signing and encryption continue without interruption.
Transactions per second the HSM can perform — the key metric if you're signing invoices, eSign requests, or payment authorisations at scale.
Spreading requests across multiple HSMs so no single device becomes a bottleneck during peak transaction periods.
Generated and used inside certified hardware — never exposed as plain files on any system.
Key operations don't become a single point of failure — clustering ensures continuity.
Meets audit requirements across BFSI, government, and enterprise environments.
Scales from a single application to enterprise-wide, multi-application key services.
