Transport Security International (TSI) is the only dedicated global journal for transport security and is regarded as “must-read” by most security professionals. Established in 1993, TSI’s leading brand status is supported by the fact that it is the chosen principle media sponsor to many of the world’s leading transport, aviation and security events, including IATA’s AVESC World. TSI is distributed to, and already viewed by, over 20,000 people in both PRINT and DIGITAL formats in more than 180 countries. Published bi-monthly, TSI includes a broad-range of topical articles addressing incidents, technologies and factual information, supported by regular features such as the Editor’s (Joy Finnegan) Lead Editorial, Industry News, Security Calendar and a Personal View from an industry spokesperson. One of the most popular sections is the TRANSPORT WATCH which reports on the latest hijack, sabotage, unruly passenger, and legal incidents of interest to the security community.

Verdict
The clearest difference is in-app purchases: SignaSource Text Imprint at none against TSI Mag's 1. SignaSource Text Imprint also leads on update cadence (daily vs every 16 months) and rating (5.0 vs 4.8). TSI Mag's advantage is ratings volume (16 vs 2). On price, ads, device support and iOS requirement there is nothing between them.
