ABSOLUTE PRIVACY: YOUR DATA IS ONLY YOURS Unlike standard security apps on the market, SUYLEX NEVER saves, stores, or keeps the email addresses or passwords you enter during scans on its servers. Thanks to cryptographic K-Anonymity algorithms, your searches are conducted completely anonymously and encrypted (hash). Once the query is finished, everything is deleted from your device. Even we cannot see what you search for! IDENTITY AND BREACH MONITOR Instantly see if your passwords or email accounts have been leaked by cybercriminals in the past. Searches across billions of rows of global cybercrime records are completed in total privacy, without your real data ever leaving your device. AUTOMATIC LEAK RADAR (24/7 PROTECTION) Your protection continues even when you close the app! The email accounts you add are automatically audited in the background at your specified intervals. The moment a new data breach involving your information occurs in the cyber world, you are instantly warned via the smart notification system. Learn about threats before they cause damage. DEVICE HEALTH AND NIST AUDIT Could your phone's operating system be manipulated? We test your device's core security using international NIST cybersecurity standards. Verify your device integrity by detecting hidden Root/Jailbreak access, modified malicious apps, and security vulnerabilities. DIGITAL FOOTPRINT AND NETWORK SECURITY Calculate how much privacy risk your social media habits pose to your profile with the "Digital Footprint Score". Additionally, instantly audit the encryption strength and cyberattack (DNS poisoning, etc.) risks of the public Wi-Fi networks you connect to. PROFESSIONAL SECURITY REPORT (PDF) Turn all your security scan results into a detailed PDF report with a single tap.
