Phorm - Webwise

Written 15 years ago by Mike Cardwell

BT has signed up to using a system called Webwise from a company called Phorm. Once they have finished integrating it with their ISP systems it will intercept and scan all HTTP requests, building up a profile of what you as a user look at online. The system will later use this data on partner websites to send targeted advertising to you.

Virgin and TalkTalk are also looking into using this technology, although they haven’t committed to it yet.

If you run a commercial website selling stuff, Phorm will intercept some of your visitors traffic and will link your products to their profile. The user will then get adverts for your competitors websites. Yes, I am not kidding. Fortunately, as a website administrator you can add your website to their exclusion list by sending an email to See here for further details.

If you run a website, there is no advantage to you of letting Phorm intercept your users traffic. Get yourself excluded!

UPDATE: I sent the following email on the 26th of March:
