I would highly recommend taking a SANS course if it becomes available to you through your employer, or if you happen to have roughly $10,000 sitting around waiting to burn.
I have not taken the exam yet, but the training was with Dr. Cole and he made it engaging and relative every step of the way. He has a ton of experience and has taught the course for 18 years. He also wrote the course material.
I know it is not in the budget for personal training (not even close for me), but if a company is willing to foot the bill it is completely worth it. Even if you have something like Security+, it is worth considering GSEC, because it is much more in-depth and you will learn considerably more than just the course material in the books.
