The only requirements for this were for it to work in both light and dark background and to have a sword and a shield, for that last one I went with an implied shield, a parted per saltire, to be more especific.

Hi!
Sword & Shield is an upcoming security system for tech companies. Our software includes password protection, server backups, malware protection, and more. We're focused on appealing to medium to large scale technology companies.
For our logo, we'd of course love to feature a sword and shield! Our team has discussed some ideas but we'd love to see what you come up with first.
We ask that the logo be provided in both a dark background and light background style. Thanks so much!
