Career Advice for "Long Term Unemployed" in InfoSec
Hello everyone!
I kind of need some advice right now in my life in my field.
I have been particularly in the Info Sec field professionally for  3.5 years, but have been self learning and passionate about IT and Net  security since 2005.
Back in January of this year, I was, for a lack of a better word,  let go of my first job in IT/IS with a small company due to not seeing eye to  eye with the company management.  To be honest, I regret it as I wanted  to bring up some issues about the direction of the company and how to  address some of the toxic issues in the environment with management but  of course it didn't go well.  They basically wanted me to beg for my job  and I refused, as they didn't want to address anything going on.  It  was a bad decision on my part to bring up the specific issue, and I feel  maybe I should have begged at this point, and tried to focus on looking  for another job in the meantime.  After all, this was my first job/only  job in the field in a corporate environment, and now I have been  unsuccessful in gaining employment since.
However more to the point, here is the current issue.  I feel  like I am being left behind in the field.  I have been unemployed since  January 2015, and I feel that everything I "learned" with the company really  wasn't what the industry followed in information security, or IT, at least in terms of what I learned.  For example, I see plenty of jobs for "security analyst" or "security engineer",  but they are looking for more senior roles that have certain skills  that I lack, despite being in my role of managed security engineer for  3+ years.  Also, no training was provided at my first job besides what  to do for the job nor any kind of guidance on what to pursue in terms of  certs, as the company didn't believe in "certs".  So right now, I'm  working on my CCNA, ISC(2) SSCP, Checkpoint CCSA, and Palo Alto PCNSE6 (self study) in an attempt to prove my skills to employers.
Is this the right move or what else should/can I be doing?
P.S.  I have a BS in Information System Security, and have a expired CompTIA A+ if that helps.
