learning hardware firewalls
what is the best thing to do when it comes to learning how to configure hardware firewalls. Manufactures of hardware firewalls seem just like antivirus programs. So many to choose from. I’ve seen jobs asking for experience on firewalls, but they always seem to be specific. One may ask for Fortinet the other may ask for another Palto alto etc. And these are just 2 vendors out of several. I’m concerned that if I chose one vendor then the employer may want another. It’s asking a lot of a person to be fully trained in all these manufacturers. Any suggestions on how to go about preparing myself. Should I choose Fortinet, palo alto, or some other vendor like that and just learn it.
