Secure Shopping
Comodo Secure Shopping is a major new feature in CIS which provides unbeatable security for online banking and shopping sessions. When using Secure Shopping, websites will open inside a security-hardened virtual environment that is isolated from the rest of your computer. This creates a threat-resistant tunnel between you and your target website which cannot be monitored or attacked by any other processes running on your computer.
- Hides sensitive online data from other processes on your PC
- Prevents keyloggers from recording your keystrokes
- Warns you if there is a remote connection to your computer
- Stops hackers and malware taking screenshots of your session
- Detects fake SSL certificates to stop man-in-the-middle attacks
But Secure Shopping isn't just for the internet! You can run any application which handles sensitive information inside a secure environment. Examples include:
- Email applications like Outlook and Thunderbird
- Accounting software like Sage
- Password managers
- Spreadsheet software like Excel
- FTP and VPN clients
- Instant messaging and chat applications
- File sharing clients like DropBox
Applications inside the secure environment are totally sealed-off from other processes on your computer - meaning there is no way that malware can gain access to your data.
The technology behind Comodo Secure Shopping is already being used by major point-of-sale and money-wiring organizations to secure sensitive customer transactions. With CIS, Comodo brings this same level of cyber security to your home. If you need a truly secure place to work and go online, then use Comodo Secure Shopping.

Is it the firewall, the behavior blocker, the sandbox, or the antivirus which is stopping it? Comodo's new unblock applications feature allows you to release applications with a single click from whichever security component has blocked them.
