Traffic from this IP address might appear to be malicious, but it is not.
You are seeing this message because you entered the IP address of a Barracuda Vulnerability Remediation Service scan node into your browser. The Barracuda Vulnerability Remediation Service is a web application vulnerability management tool used by authorized individuals to scan sites they control. It finds vulnerabilities such as SQL Injection, Cross-Site Scripting, and others.
Although traffic generated by a web application vulnerability scan might look malicious, it is not. Traffic generated by the Barracuda Vulnerability Remediation Service is specially engineered to determine if a vulnerability exists while causing no damage to the application being scanned. Although certain firewalls might flag the traffic as malicious due to its nature, rest assured that this traffic will not harm your application.
If you ran a scan using the Barracuda Vulnerability Remediation Service yourself, you can cancel the scan at any time by clicking Cancel on your the Scanner > Scan Status page. This is described in the Actions on Existing Scans and Web Applications article. If you did not run the scan yourself, another authorized person (such as your IT provider) might be running the scan. Ask your IT personnel. If you need help, contact VRS_Support@barracuda.com.
