nShield Solo HSMs are low-profile, embedded PCI-Express cards that provide cryptographic services to one or more applications hosted on a single server or appliance. These hardened, tamper-resistant cards perform encryption, digital signing and key generation on behalf of an extensive range of commercial and custom-built applications, including certificate authorities, code signing and more.

The nShield Solo series includes nShield Solo+ and the new high-performance nShield Solo XC, which offers superior asymmetric and symmetric performance and best-in-class elliptic curve cryptography (ECC) transaction rates.
