I really like the professional image that logo
#8 and
#7 represent. However I'm not sold on the pad lock for this logo. I think that if the gray top and key hole were removed it may give us more of the feel that we are looking for. The bottom of the lock looks like a shield representing our security and the check mark is good indicating the checks and proactive nature of what we do. I'm not sure if we should replace the key hole with something else or not? Like MSG or any other idea you may have.
