ZevaCrypt
ZevaCrypt
Increase return on investment of existing PIV infrastructure for cross-agency encryption through ZevaCrypt™ intuitive and true end-to-end encryption solution. Email communication over secure channels has always been one of the most difficult-to-solve security challenges, especially those struggling to enforce the use of high assurance credentials such as PIV and CAC. Meanwhile, email is our primary form of communication for both sensitive and non-sensitive information. While encrypting within the same organization is simple, email encryption across organizational boundaries is challenging and often manual. Existing PKI encryption systems don’t ensure the required level of protection, and currently none of the encryption systems validate certificate policies the way they were designed to be used. In general, strong encryption must combine strong identity with strong cryptography. PKI encryption is the only means of achieving this intersection of goals.Starting Price: $9.90 per month -
