TL;DR - Here's the bottom line on how our iOS Security & Social Browser works: Enhanced mobile browser security with easy customization. An offline database solution to store and catalog the internet safely, including Bookmarks and Pictomarks with bookmarks encrypted automatically. A dedicated search with over 40+ search engines.

A deterrence decryption feature that allows users to view webpages relying on our new deterrence encryption technology. An iMessage extension to send encrypted text and picture messages securely. L;WR - Here's our long(er) explanation version: Mobile browsing can be a scary place. Hackers and Cyber Criminals have found innovative ways to target you on the devices and applications you use the most. Cydog Browser is a company which provides the world's leading web security for the masses. Our browser automatically blocks all non-secure http connections, leveraging Apple's App Transport Security (ATS) technology. This is the same technology Apple uses for its lockdown mode when users are being attacked by sophisticated hackers. Because we use this mode, you can't add code to reenable access to insecure connections, making your web connections more secure in the event of an application sandbox compromise. Our obfuscation mode creates web browsing entropy to make certain cyber-hijacks more difficult, decreasing Man-in-the-Middle (MitM) attacks, and our anti-cookie potentiation and web firewall technologies block insecure events, making a user's clicks an active cybersecurity technique to trick sophisticated hackers. This browser is meant for minimalists who want automated features without the cybersecurity hassles. We hope you enjoy better mobile browser security with Cydog Browser!
