Lunar Defense helps you understand the security of your device without sacrificing your privacy. Run a sweep at any time to verify device integrity, inspect your network environment, and identify signs that may indicate tampering, interception, or unauthorized modification. Check a suspicious link or scan a QR code before you tap through. Every result includes a clear explanation of what was checked, what was found, and what it means. Unlike many security products, Lunar Defense performs its analysis directly on your device. Your scan results and personal information stay on your phone. FEATURES • Device Integrity Checks Verify that key iOS security protections appear intact and look for indicators commonly associated with jailbreaks, code injection, debugging, or other forms of device tampering. • Network Security Analysis Inspect your current network environment for proxies, VPN-related interception indicators, and secure connection validation issues. Trust a VPN or proxy you use on purpose? Mark it as approved so it stops showing up as a concern. • Link & QR Code Checker Paste in a link that looks off, or scan a QR code before you visit where it leads, and Lunar Defense checks it on your device first. Add the surrounding message text for a closer read. Nothing about the link or message leaves your phone. Requires a device that supports Apple Intelligence, with Apple Intelligence turned on. • Clear Security Reports See exactly what was checked, what was found, and why it matters. Every finding includes plain-language explanations and recommended next steps. • Privacy-First Design Analysis is performed on-device. Scan results are not uploaded or shared. WHAT LUNAR DEFENSE IS AND ISN’T Lunar Defense helps identify indicators that may suggest security risks on an iPhone. It does not claim to detect every possible threat, and a clean scan should not be interpreted as a guarantee that a device is completely secure. Instead, Lunar Defense provides transparent, evidence-based security verification designed to help you make informed decisions about your device’s security. Built by security professionals. Designed for everyone. Lunar Defense Pro is an auto-renewing subscription. Payment will be charged to your Apple Account at confirmation of purchase. The subscription automatically renews unless canceled at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. You can manage or cancel your subscription in your Account Settings after purchase.
