A cyberpunk digital fortress floating in neon-lit cyberspace, with two distinct protective barrier layers surrounding it - an outer translucent shield crackling with electric blue energy representing client-side defenses, and an inner solid geometric barrier glowing deep red representing server-side protection. Data streams visualized as glowing particles attempt to pass through both layers, some bouncing off the outer shield, others being filtered by the inner barrier. The fortress itself resembles a crystalline database structure with pulsing circuits. Dark background with purple and magenta fog, reflective grid floor stretching to infinity, rain falling through holographic projection beams.
