Probably security+. I feel I can skip it and move straight on to CEH, OSCP or even the new eLearningSecurity cert. But I don't have any certs and it seems like it's a good "intro" cert, even though I feel my knowledge surpasses the info on the exam.

Unless you're planing on moving somewhere you can dive a lot and don't mind being a boat hand, or planing to go on to become an instructor I wouldn't mess with the PADI Divemaster.

I was an SDI Divemaster. Most of my time after getting it was spent working with students, assisting the instructor, being the victim for rescue corses, or working toward my instructor cert.

The other guys I knew that were dive masters, on occasion got to lead dives, but most of the time were deck hands on the dive boat. Getting the divers in and out of the water, cleaning the boat after returning to dock, and doing the general maintenance on the equipment. It was rare for them to get in the water.

I'm not saying I didn't enjoy it. I mean where else are you going to be legally allowed to jump from one boat to another and tie it up to yours?

For me it would certainly have to be  Advanced Penetration Tester Course.  It certainly isnt an industry recognised course to perform (like heorot and elearnsecurity i guess) but sounds like it would be very worthwhile.
