Enhance the return on investment for current PIV infrastructure in cross-agency encryption by utilizing ZevaCrypt™, a comprehensive and user-friendly end-to-end encryption solution. Email communication, particularly over secure channels, has consistently posed significant security challenges, especially for those tasked with enforcing the use of high assurance credentials like PIV and CAC. Given that email serves as the primary communication method for both sensitive and non-sensitive information, the importance of secure exchanges cannot be overstated. While encrypting emails within a single organization is relatively straightforward, achieving encryption across different organizations remains complex and often requires manual intervention. Existing PKI encryption systems fall short of providing the necessary level of security, as they typically do not validate certificate policies in accordance with their intended design. It is essential to understand that robust encryption must integrate strong identity verification with advanced cryptographic techniques. In this context, PKI encryption emerges as the sole method capable of fulfilling this essential convergence of objectives, ensuring that sensitive communications remain secure across various agencies.
