This is the only correct answer, exhibitors are responsible for going a step further to protect their property, especially if extended protection is offered.
Get your own security, hire Gamescom Security, get insurance or deal with the damage.
Alternative: Higher costs @ Gamescom
We are aware of stolen hardware and take these reports very seriously and understand the frustration of affected exhibitors.
Since many requests reached us, we would like to inform about general security regulations at the event:
Uniformed guards provide general security across the venue. Individual stand security can be booked separately, and exhibitors are advised to insure equipment against theft.
This is noted in the terms and conditions of participation and the technical guidelines.
All cases have been reported to us and to the police, and investigations are already underway.
We also want to ensure that the reported cases are individual cases, which we are very sorry to read.
Because security has one of the highest priorities to us as an event and to see that indie developers are affected makes us very sad. At an event of this size, however, there will always be individuals attempting to take advantage of the situation.
Our security measures are designed to minimize such risks as effectively as possible.
