I'm at SANS CDI 2008, and just completed day 2 of the GIAC Security Expert (GSE) hands-on labs. I just got the good news that I passed!!
The prerequisites for attempting the GSE are the GSEC, GCIA, and GCIH certifications with 2 of 3 gold.
Then it requires a 4-hour multiple choice exam, followed by 2 days of hands-on exercises.
The 16 hours of hands-on exercises were tough, but very fair. It's great to be done.
I'll share more thoughts after I return from CDI.
