Public WiFi & eSIM Safety Scan

Is this public WiFi safe? SentryFi is a WiFi security checker for hotel WiFi, airport WiFi and your travel eSIM. In about a minute you get a 0–100 score, the reasons behind it and plain next steps before banking, email or work. WIFI SECURITY CHECK, STEP BY STEP Watch each check finish, one by one: • Open or locked network, and how it is encrypted • Captive portal: is there a WiFi login page, where does it come from, is it encrypted (HTTPS)? Open it with one tap • DNS check: does this network answer the same as trusted encrypted DNS? • Certificates and unchanged pages, signs of an HTTPS downgrade or a hidden proxy • Speed, latency and packet loss • 50 popular sites tested, to reveal hotel, school or work filters MOBILE DATA & TRAVEL eSIM CHECK Not on WiFi? Check your SIM or eSIM line too. • Line identity: the country and network your traffic exits through, for everyone. Handy abroad, since many travel eSIMs route data through another country. Pro adds shared IP (CGNAT), IPv6 and DNS privacy • Carrier tracking: does your carrier add tracking headers to your traffic? Everyone sees the result; Pro names the header. "None found" means not detected in this test, not a guarantee • Blocked sites: 50 popular sites tested on your line. Count for everyone, the full list in Pro. Info only, never lowers your score • Speed and latency: good enough for video calls, gaming or 4K? WHO IS ON MY WIFI? A SIMPLE NETWORK SCANNER In about 30 seconds the SentryFi WiFi scanner lists the devices answering on this network by type (phone, computer, TV, printer, router, smart home) and tells you whether they can reach your phone. Pro shows every device by name, IP and type. Home alerts: see what joined your home WiFi each time you open the app. HOTEL, AIRPORT, CAFÉ SentryFi explains what this network can and can't see about you, with tips for the place you are in. If a network you checked before comes back with different DNS, encryption or login page, SentryFi tells you it looks different. It could be the venue, it could be a copycat network. Siri and Shortcuts: say "Check this Wi-Fi", or add SentryFi to a Shortcuts automation so it opens each time you join WiFi.

NETWORK SECURITY WITHOUT A VPN SentryFi doesn't change your connection or sell you a VPN. No account, no sign-up, no VPN profile. We never ask for your WiFi password, and your history stays on your phone. It checks, shows what is there and lets you decide: stay, take care, or switch networks. Results are risk signals, not a guarantee. The basic version shows ads (Google AdMob); Pro has none.
