Hi I'm quite new in the world of firewalls and was today looking around for some study material for CCSE, I got access to a udemy ccse R81 course, the R81.10 ccse material on kortext and was planning to set up the lab environment at home to work with while also working with checkpoint environments during the days. For the ccsa it felt like there were tons of material but for this I haven't found anything on cbt nuggets, the ones on YouTube I don't know if they are outdated. Do you people have any recommendations?
