DigiSAFE Authentication Server – DAS

Within today’s Internet environment, cyber threats has become a prominent issue especially in enterprises that offers online application and e-services. Access control with a simple ID and password is no longer sufficient in face of all these threats. These credentials can be easily hacked and obtained through phishing, key loggers, social engineering, Trojan Horses, etc.

To enforce and protect the interests of enterprises and their users, a second-factor authentication (2FA) is introduced. This system allows a second layer of authentication via hardware token or mobile code.

Different layer of security may require different kind of transaction depending on the sensitivity. This system offers 3 types of 2FA for the different requirements of each enterprise; normal One-Time Password (OTP); Challenge Response and Transaction Signing.

DigiSAFE authentication server is designed to meet government and financial institutes’ stringent security and availability specifications. It has been deployed and is currently providing 2FA for various web portals, VPNs, operation system, logins, network devices and emails in government, financial institutes and online healthcare services.
