Ocius Sentinel
Retailers accepting card payments must achieve and maintain PCI DSS compliance to help protect sensitive cardholder data, but with this comes a significant financial cost that can run into millions of pounds for large retailers.
Commidea has developed Ocius Sentinel; a solution that will help you achieve and maintain PCI DSS compliance at a fraction of the cost and secure sensitive cardholder data.
Developed in-house by Commidea, Ocius Sentinel is a software application that resides on a PIN Pad within a PCI PTS/APACS Common Criteria secure environment providing dual-layer data encryption from the point of card data capture.
Sensitive cardholder data is encrypted by the PIN Pad using 128 bit 3DES encryption, utilising a unique dynamic key system generated using merchant and transaction specific data elements. This data is then further encrypted using a 2048-bit RSA algorithm key, before being sent to the Point of Sale.
As card data remains fully encrypted throughout this process, and the merchant has no ability to decrypt the data, cardholder information is effectively removed from the merchant's system, significantly reducing the scope and cost of achieving and maintaining the Payment Card Industry Data Security Standard. Cardholder data is only decrypted inside the secure environment of Commidea's ICP Managed Service prior to transmission to the acquiring bank.
Ocius Sentinel is the final piece of the jigsaw to provide end-to-end encryption of cardholder data significantly reducing the scope and associated costs of PCI DSS compliance for merchants. But Ocius Sentinel goes beyond compliance and can provide a range of additional features, addressing issues such as PED Asset Management, including PED serial number tracking and swap out/power on-off alerts to help thwart physical attacks on PED assets.
Merchant Benefits of Ocius Sentinel
- Merchant no longer has access to any sensitive cardholder data
- Effectively removes merchant PoS and associated network from scope of full PCI DSS audit
- Reducing scope dramatically reduces the substantial cost of PCI DSS compliance for merchants, large and small
- Encrypted offline transaction storage now on the PED
- Dual Layer Encryption system, utilising 3DES Dynamic Key encryption and 2048-BIT RSA encryption
- Sophisticated PED Asset Tracking and Management System
- A mutual authentication system to ensure that data is only sent to and from genuine Commidea servers
- Online reporting of unusual or unexpected PED activity
