Secure as hell...
The mission of our project is to bring Lychee Linux to the business. In order to accomplish this we had to build a big security infrastructure.
For the most people it is very hard to work efficiently and stay at the same time secure. They either have not got the time to look closely on their security or just do not care. We want to offer the best security by default. We try to accomplish this by using of course Linux and many security tools like AppArmor which is very famous.
It is hard to set up a secure work environment which works efficiently but I think we did quite well.
You do no need some kind of expensive security suites. We use open source or free software to help you being secured.
We do not want to advertise with the almost virus free Linux system but it is a clear fact. In order to secure your colleagues who might be using Windows or Mac we have installed the Clam AV software which lets you stay almost immune.
