OSEE — OffSec Exploitation Expert

The most difficult OffSec certification and arguably the hardest practical security certification in the world. Covers advanced Windows kernel exploitation, advanced heap exploitation, DEP/ASLR/CFG/CET bypass techniques, and custom vulnerability research. 72-hour practical exam. Training requires in-person attendance at Black Hat — not available online. Cost approximately $10,000-$12,000. Held by a handful of practitioners globally. For serious vulnerability researchers and exploit developers this is the definitive credential, though its rarity means most employers cannot properly evaluate it.
