There is always someone who is willing to go to work in a potential high risk part of the world - for a premium price.
If the company recruiting do not make it clear where you will be going you do not have a chance to make a decision with regards the simple equation - does the pay justify the risk?
For what its worth, my thoughts are if the company have not undertaken the recruitment process with transparency (perhaps to keep the staff from wanting pay proportionate to the risk) then don't expect a high standard of transparency with regards the measures that they will put in place to protect staff, at best those measures may be excellent, at worst you risk death.
A secure compound could be anything from a fence to an enclosure contained within a blast proof wall with 24 hour ex special forces "employee's" providing 24 hour close protection.
Who is going to tell your next of kin if they get it wrong?
