Looking for security / performance experts

Why do you not try a real question here and now. You may get an answer that others might also find useful. Or try stackoverflow or security.stackexchange.com/ etc.

The point is that many hundreds or even thousands of people might read the answer and benefit. Also, how could you be confident if expert A says do this, how can you know if that is right, up to date, or of any alternatives? Communities can help you here, because your question might spark a conversation exploring the topic from many angles.

A single more focussed question is better than multiple questions all thrown in at once. Ask your best, most trying question, the one that will benefit you most first, and lets see how we do with that one first.
