Off the top of my head, you can get some valuable information in the 2600 quarterly magazines. I'm sure you can google and find some Phrack magazine issues. Other than that, try Information Security magazine.
Don't know many other English security magazines beside Hakin9, Phrack and 2600.. You may find a few more on Wikipedia though. Unfortunately most e-zines are only available for a short period and die then. You may also like (In)Secure Magazine.
You could take a look at SC Magazine may be more marketing/managerial than you're looking for but always worth a skim to keep upto date with the latest trends. As well as the print version the online articles can be good quality if you find something that you're interested in.
Other than that, another vote 2600, Hakin9 & Phrack
