A UK based market intelligence group, TechNavio, has reported that the increasing uptake of internet traffic snooping technology (Deep Packet Inspection) by broadband ISPs will help the global DPI market (currently estimated to be worth £282 million) grow by around 30% each year to just over £1 billion in 2015.

DPI solutions are used by ISPs for all sorts of tasks from Traffic Management to security. However it can also be used for the questionable tracking of customers private online activity, which in some cases (e.g. Phorm ) has appeared to go too far.

Phorm worked with UK ISPs, such as BT (WebWise), to monitor what websites you visited for use in targeted advertising campaigns. However some providers caused an outcry because of the way that they chose to track their customers private online activity without consent.


Governments have also been increasingly adopting this technology for enhancing national security against advanced cyber-attacks. However it's estimated that most of the growth and demand for DPI solutions will come from USA based ISPs.
