Think of a family crest without it being "too busy".  Perhaps the crest itself is a shield or a house with  a family inside.  One of the examples above has a shield with a house inside which is nice.  Don't like the office buildings in it.  

Also attaching two other pictures.  One has a shield with a family in it.  Don't like the way the family looks but the idea could be good if done well.  Other is a knight / soldier with banners.  Don't necessary want a soldier but the banners might work for the name of the "Family Safety &amp; Security.  

With all of that said.  Don't just try this.  If you can come up with something better, go for it.
