SEQUI's VPN product family conforms to IKE and IPsec standards that are specified within the RFCs and Internet Drafts from the International Engineering Task Force (IETF).

IPSec and IKE are today's industry-leading standards for deploying IPSec VPN service. The standards combine tunneling, encryption, authentication, and keying technologies to secure communications. Data is safeguarded by AES, the IPSec declared choice for strong encryption.  Keys for the encryption process are dynamically created for every VPN connection as specified by the Internet Key Exchange standard. Invisible, periodic key regeneration maintains high integrity of encryption keys.
