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.
