Passed CCNP, should i go for the CCNA Sec now?

Hi I passed the CCNP R/S earlier this year and if i'm being honest security has always interested me the most in networking, i'd probably rank them as follows:

Security
R/S
Wireless
Voice (really dislike voice)

I'm wondering if it's worth going for the CCNA security? I feel like i'd be able to pass it but is it worth it now after getting the CCNP and would employers even look at it?

Thanks
