One of the startups that participated in our couses in their early stage – LaptopLockware from the MAN 633 course - just launched their product. They developed a programme that is able to protect your laptop from theft. Therefor it connects to the power cable und receives a signal when the laptop is disconnected. The programme then starts an acoustic alarm and sends you a message on your phone.
Since the exam period is currently on they decided to make the software freely available for students until the end of the exam period. In case you are interested visit their website for more information: https://laptop-lock.de/wp/
