Secure vs. Unsecured Connection Icons - Visual Security Indicators #3663889 (License: Personal Use)

The image displays two stylized padlocks against a black background: a vibrant green one with its shackle down (locked), signifying security, encryption, or verified authenticity; and a bold red one with its shackle raised (unlocked), indicating vulnerability, lack of encryption, or unverified access. Both feature centered keyholes and use high-contrast colors for immediate visual recognition in digital interfaces.

Commonly used in web browsers, security dashboards, privacy policy pages, and educational content about HTTPS, SSL/TLS, and online safety to visually communicate connection status at a glance.
