I like the energy of #25 don't love the shape inside. #23 I love the text and the shield but don't like the way the house looks. It makes me think of an old floppy disk not a house.
To be fair to veo who did it first.. if you can maybe do something other then a house in the shield.. I like your work. Maybe you can put keys inside instead? House inside the shield says home security to me anyway.. which is not what I am going for here. The secure transfer of information is what I am trying to convey about anything else.
