Several times on the forums the people is asking: What certification take first OSCP or eCPPT?
The answer depends of how you learn. Everybody learn in a different way, we will mention two of those:
1. Some people like to learn something basic and then they want to practice and practice until they learn an objective.
2. Some other people like to learn slowly, building step by step knowledge and practice until they learn an objective.
If you are the type for the Option 1 then you need to go straight to OSCP, this kind of certification is very practical and you need to study for yourself a lot.
In the other hand, if you are the type of the Option 2 then you needs to go first to eCPPT and then OSCP, the eCPPT is a training that build up your knowledge and skills slowly.
Remember, Penetration Testing is a field where you always learn and learn.
