> Guess what, my friends who are not software developers usually also have company laptops and phones – and like it that way.

Interesting. So you have certainly managed to avoid the trend. Because statistic doesn't support your words at all: 87% of businesses are dependent on their employee’s ability to access mobile business apps from their smartphone and 67% of employees use personal devices at work.

I would guess this percentage is smaller in US and EU and bigger in third-world countries (almost all my friends from Egypt, Iran and Russia don't know about BYOD or any such fancy acronyms because no one ever thought about providing them with company smartphone and very rarely they got a company-provided laptop), but Bitglass, the Next-Gen CASB company, is based in Silicon Valley with offices worldwide — and it observes what I observe and not what you and Wol are observing.

And while your words sound convincing — they don't explain why things you observe and independent statistic observes don't match.

Because statistic very clearly shows that use of personal devices for work purposes is growing, not shrinking and the mitigation strategy chosen by the Industry is to make them… “less pesonal”, I guess: make sure bootloader is locked or security enclaves are installed (things like Intel SGX are developed for that purpose) and so on.

Add to that the fact that states (not just China or Iran, but also EU and US) increasingly want to ensure that nefarious sites they want to ban remain inaccessible to the most of the population — and you can easily imagine where all that is going.

There can also be regulatory-environment issues that work against BYOD. Here in Germany (as in the rest of the EU) there are very strict personal-data protection requirements that need to factor into companies' risk assessments. Many companies reasonably conclude that having customer or client data stored on (or even accessible from) employee-owned hardware is not a Good Idea, due to compliance issues and the increased risk of data breaches and associated fines/bad PR.

(The article you cite looks interesting but the statistics it quotes seem fishy in various respects. It is also tainted by the fact that the author himself seems to be a big fan of BYOD. I probably wouldn't want to lean on it too heavily for support.)

The statistics are interesting, but I wonder if they're skewed by many companies having people log in remotely via Citrix or just using an online website or some such. Then sure, users can use any computer they like, it doesn't matter. Similarly, if the phone is only used for phone calls and no actual data is stored I can imagine the "using own phone for work" is doable.

The GDPR basically makes storing company data on uncontrolled personal computers a non-starter for most businesses. But remote access gives the user a controlled system, and web-browsers promise not to cache data fetched via TLS.

They can of course say you have to bring your own device otherwise they won't hire you. On the flip side, they're not allowed to just randomly add monitoring to your personal device and if anything goes wrong (like your home laptop gets hacked) you as employee bear no liability. Which is why companies often hand out laptops anyway because as owner they have many more possibilities to secure the device.
