Imperva Cyber Community

Hello,

A major certificate authority with a significant share of the market in Japan has stopped issuing 2048-bit certificates and will now issue 4096-bit certificates instead.
We understand that Imperva has not supported 4096-bit certificates since December 2024.

Many of our customers are currently using certificates issued by that certificate authority, and we are asking them to switch to another CA. However, we have received many requests from our customers asking for support for 4096-bit certificates to be reinstated.

We understand that there may be no current plan to resume support, but we would greatly appreciate it if you could consider supporting 4096-bit certificates again.

Thank you,
