Radicati On Tech

I recently came across the Radicati Market Stats & Industry Commentary and thought it worth sharing.


  • In 2005, each email user will have an average of 1.75 mailboxes. This figure will grow to 2.0 mailboxes per user by 2008.
  • MS Exchange revenue is approximately $1.6 billion in 2005. Over the next four years, MS Exchange revenue will increase at an average rate of about 10% totaling $2.4 billion in 2008.


Worldwide email traffic will increase at an average annual rate of 21% over the next four years, totaling about 195 billion messages per day in 2009.

  • Commercial advertising, the most common form of spam, accounts for 58% of worldwide spam traffic.
  • We anticipate the market for Full Suite products to be one of the fastest growing segments in the security industry-in fact, revenue is expected to grow from $185 million in 2004 to $492 million in 2008.
  • If nothing is done to stop the increasing growth in phishing attacks, we anticipate the number of unique phishing attacks will grow from 51 unique attacks in 2004 to 404 in 2008.


  • In general, we estimate that in the directory space for every $1 spent on products, an additional $3 is spent on professional services.
  • We estimate the installed base for NOS (Network Operating System) directory services will increase from 279 million entries in 2004, to over 518 million entries in 2008.


  • We project that by year-end 2008, there will be 873,600 WLAN hotspots worldwide, an increase from 70,000 in 2004.


  • The full suite segment of the Identity Management market is still in its infancy – it is expected to grow substantially from $170 million in 2004 to over $5.9 billion by 2008.

OK so let’s sum this up. Spam and phishing will become more and more of a menace, Microsoft will rake in more and more money and hotspot growth will increase nicely. Oh, one last thought -- we will all have more mailboxes to check. Will this trend ever slow I wonder?
