Create a superhero inspired by Heimdall, the Norse guardian of the Bifrost bridge. Reimagine him as a modern cybersecurity expert, safeguarding digital realms from breaches. His attire should blend high-tech armor with rainbow motifs, adorned with symbols of vigilance and sound. Eyes should radiate alertness and clarity. Accessories might include headphones that detect any digital intrusion or a tablet that controls global networks. Embrace a palette of neon spectrum colors, metallic silvers, and firewall reds. Capture the essence of a sentinel ensuring the safety of our interconnected world
