Logo Design Brief
The purpose of this project is to produce a badge (or a stamp) on a box from an OEM (mobile device or consumer appliance manufacturer) that states this is 'Secured by D4'. It should be something similar to a Cisco Powered Network or Intel Inside type logo.
At Cog Systems (http://cogsystems.com) we a launching a suite of software security products. We have produced some other logos in the brand for "D4 Secure", now we seek a more concise logo or one that can be used for co-branding.
We are looking for a simple design that ideally works with our company logo theme, and promotes security, and modularity if possible as underlying themes. Our company logo (see http://cog.systems ) - it is two cogs. Also attached is one of the wining entries from our previous competition for our general logo.
Our current theme colour for our marketing material has been green - #8FC300 or #739A28, although these have been for highlights.
The font we use in our current logo branding is Eras / Eras Demi /Eras Medium. There is no requirement to use this, but keep it in mind.
