WebPKI CA Revenue

• This is intended to be an appendix of sorts for WebPKI and Digital Signature related M&A + Investment + Public Offerings
• I have been in and around this space for a long time, I know some things that are not public just like you probably do, as such I have, and will continue to excluded these sorts of details.

WebPKI and Digital Signature related M&A + Investment + Public Offerings

• This was inspired by Matt Suiche's great post on cyber security M&A related activity; there is some overlap but not much.
• This is all public data.
• I have also intentionally excluded sales of WebPKI key material, not only are these prices not public but they are usually very special cases that are in-essence impossible to compare effectively.
• I have also included HSMs, Smart card, Digital signatures and CA related software companies in this list as it seems relevant.
