ZeroDayScan in an online scanner which can scan your site for the following issues:

• Detects Cross Site Scripting attacks (XSS)
• Detects Hidden Directories and Backup Files
• Looks for Known Security Vulnerabilities
• Searches for SQL Injection Vulnerabilities
• Automatically detects zero day bugs
• Performs Website Fingerprinting

Once the service finishes scanning your site for issues and vulnerabilities, it emails you a PDF with what they found for your site.

In order to prevent sensitive security reports like this going out to others, ZeroDay scan asks you to add a text file with some security text to be added to your site. This ensures you can scan only sites which you have control over.
