The OSCP is a certification that has already gained a very solid recognition and I only hope and expect that to continue. I’ve taken a couple of other security related certifications including the CEH, Security+, CISSP and the TigerScheme QSTM. If I had to select a candidate to perform a pen test on a client network, the OSCP certified candidate would get the job every single time. Read OSCP Review

I have had extensive experience with industry certifications, and I can say without a doubt that Offensive Security trainings and certifications are in a league of their own. The training they provide develops real technical skills, forcing you to leverage what you learned to solve complex problems, rather than the traditional multiple choice question format.Read OSCP Review
