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.

On Twitter the other day, I was lamenting the state of OCSP stapling support on Linux servers, and got asked by several people to write-up what I think the requirements are for OCSP stapling support.

1. Support for keeping a long-lived (disk) cache of OCSP responses.

   This should be fairly simple. Any restarting of the service shouldn't blow away previous responses that were obtained. This doesn't need to be disk, just stable - and disk is an easy stable storage for most server

CT For Server (Developers)

Intro

Similar to my advice regarding OCSP Stapling for servers/server developers, based on questions I've received about "CT best practices," I wanted to write something similar for those writing server software. That is, this isn't targeted at server operators, but for those writing software like Apache, nginx, Caddy, etc.

At the most basic level, the deployment of Certificate Transparency to date has largely tried to focus the burden on CAs, rather than on server developers. If the CA is doing everything right,
