Data Encryption Software: In The UK, Computer Encryption Is Half Empty Glass.

Or a half full glass, depending on how you view it.  According to a study, about half of UK businesses have installed data encryption, something similar to AlertBoot, on their computers.

52% Use Encryption

According to the survey, 52% have confirmed the use of data encryption software on their laptops, 43% have say they did not have encryption deployed, and 5% said that they don’t know.

The 52% figure represents an increase from 40% when a similar survey was carried out last year.

The survey also found that only half of those polled used encryption on removable media, such as USB sticks.

Only 13% reported a data breach due to a missing laptop.

12% Growth Rate?  Nope.  Much Higher

Many are noting that a 12% growth rate (going from 40% to 52%) sounds great but is still low when you consider that nearly half the laptops out there are not adequately protected.

I’m not sure these people are doing their math correctly.  We’re dealing with percentages, where you can’t just add or subtract two percentages together and get a valid result in terms of growth.  You can talk about differences (“there’s a 12% difference”) but that certainly doesn’t imply growth.  A growth rate is the difference between A and B, based on an initial point (let’s designate it A).  For computational purposes, let’s assume that the percentages correspond to the number of computers.

That would mean that there were 40 computers encrypted last year, and there are 52 computers encrypted this year.  So, (52 – 40) / 40.

That’s a 30% increase.  That’s huge.  That’s enormous.  If you change the numbers to 5,200 and 4,000, or some other fixed ratio, you’ll still get that same 30% figure.

I can understand looking at the data security landscape out there and regarding it as full of holes and weaknesses.  But, if you’re dealing with real world aspects, you have to compare the (correct) results with how the real world works.  A 30% increase is something to be congratulated — and looked upon as a glass half-full.

Of course, that rate is bound to drop off.  A continued 30% growth rate would imply that all laptops in the UK would be encrypted three years from now.

(All of this assumes, of course, that the number of laptops being used in the UK remains about the same throughout the years.)
