Excrypt Plus Payment Hardware Security Module (HSM)

Payment and general-purpose HSMs are optimized for different IT environments. A payment HSM might be designed to handle hundreds or even thousands of payment transactions per second. On the other hand, a general-purpose HSM might specialize in use cases outside of payments. This could be encrypting files and applications, creating and signing encryption keys, acting as a certificate authority (CA), and authenticating client devices across a network. In summary, the use cases an HSM must fulfill are determined by the environment in which it will be deployed.

Your processing throughput (in transactions per second, or TPS) will depend on several factors, such as the scale of your operation, number of customers and partners, and how your infrastructure is setup. Small and mid-range organizations typically start with between 250-500 TPS and scale upward. Larger organizations tend to base their estimated processing needs on their previous needs as well as any planned expansions. The Excrypt Plus offers highly scalable transaction processing speeds, from a few hundred TPS up to several thousand.

A payment HSM is a physically and logically secure device that performs cryptographic operations. Payment HSMs are often used to encrypt payment transactions and manage payment keys. The descriptor “payment” refers to the payment processing environments in which they are commonly deployed. They can be integrated into a wide variety of different environments and customized for diverse use cases.

Payment and general-purpose HSMs have several things in common. They both protect sensitive data by carrying out cryptographic functions. For example, payment and general-purpose HSMs might run encryption algorithms, create keys, or manage sensitive data. The key difference is what kind of IT environment they’ll be deployed in, and which use cases that will entail.

Rapidly encrypt & decrypt sensitive payment data in a PCI-DSS compliant HSM
Electronic payment networks need data security solutions that scale in speed and can expand over time to support emerging payment types and algorithms. The Excrypt Plus meets and exceed those needs, offering complete and robust transaction security at speeds of up to 5,000 transactions per second (TPS). With integrated disaster recover and redundancy features to ensure rock-solid reliability, the device complies with key management best practices and contains some of the industry’s most advanced security features.

Strategic integration
Strategically integrating the Excrypt Plus with other Futurex products paves the way for even faster speeds, higher availability, and fuller functionality to meet the most demanding requirements. It is compatible with Futurex solutions including the Guardian Series 3 and the Excrypt Touch, to create a fully redundant, remotely managed cryptographic infrastructure.
