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.
A Hardware Security Module (HSM) is a dedicated, tamper-resistant computing appliance engineered to generate, safeguard, and manage cryptographic keys within a certified physical boundary. Unlike software-based keystores where private keys risk exposure in memory or file systems, an HSM ensures private keys never leave the secure hardware perimeter in unencrypted form.
All cryptographic processing—whether high-throughput RSA/ECC signing, payment PIN block translation, or database encryption—executes directly inside the hardened module. Client applications interact via standard PKCS#11, Microsoft CNG, or RESTful APIs, receiving cryptographic outputs without ever touching the underlying key material. Compliant with FIPS 140-2/140-3 Level 3 and Common Criteria EAL4+, Care4Sign provides robust Network, PCIe, and Cloud HSM solutions tailored for Indian banking (RBI cybersecurity compliance), Certifying Authorities, and high-volume corporate document signing pipelines.
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 physically detects intrusion attempts and zeroes out sensitive cryptographic keys immediately.
An internationally recognised evaluation of the device's security architecture and cryptographic implementation — mandatory for government and defense procurement.
Strict compliance standard for payment card PIN handling, tokenization, and transaction authentication across banks, ATMs, 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.
