After 30+ years of experience working for major STM publishers, PSI was created by two veterans of the field that realized the extent of IP misuse and subscription abuse. We have since made great strides towards rectifying the problem. We have partnered with IANA for increased IP lookup accuracy and cross referencing between publishers, and throughout the past 8 years have serviced over 20 million
IP address records from over 40 of the world’s largest publishers. We guarantee to always maintain secure, confidential and independent practices, and are compliant with the Data Protection Act 1998 and Confidentiality Disclosure Agreement.
