An acquaintance of mine asked me to redesign a logo for his company—and here is the result.

He felt that the old one was outdated and did not look modern enough.

As you can see above, the old version of logotype (and Corporate identity) used a combination of black, grey and green colours. These were asked to be kept in a new design. The company specializes in full-service network solutions, and their employees have either Microsoft Certified Professional or Cisco Networking Academy certificates.

And below you can see the horizontal variant of the logo, followed by the black-and-white alternatives.

And I also attach some of the raw concept stages from the thinking process :-)
