    Does Cloud WAF support Elliptical Curve Cryptography on customer supplied certificates when onboarding a website ?

    @Robert Kemeny, I spoke to @Phil Klassen and @Peter Klimek, some of the Imperva experts and they said, we support Diffie Hellman E ciphers - the answer is yes we do. This is ECDHE which we do support and generally most browsers will use as the default option in negotiating TLS connections. Does this answer your question?

    Also, ECC  or ECDSA are not support, at this moment Imperva use all of our certificates are RSA ones.
    Currently we don't support it as part of CWAF and there is no ETA. We are checking to see if it's possible to use custom cert and not from Imperva. 

    Here is some documentation that could help
