Design a pictorial mark logo that represents Sacumen's expertise in connector development and security services. The logo should be modern, minimalist, and bold, with a color scheme that reflects the company's commitment to innovation and timely delivery. Consider incorporating elements that symbolize security and connectivity, such as locks, keys, or network cables. The symbol should be distinct, recognizable, and able to stand alone or be paired with text. The use of flat vector designs and minimalistic styles is encouraged to create a simple yet impactful logo that effectively communicates Sacumen's brand identity and values.
