Access your website or application behind a firewall, on a staging server, or locally with CrossBrowserTesting's secure tunnel technology. There are many reasons to keep a web application behind a firewall. Protecting unsecured data and credentials, hiding new features, and general security are all common concerns of software teams. When you connect to our local tunnel, you get access to every part of CrossBrowserTesting including screenshots, live testing, and test automation. Local Connection has three modes, allowing you to use our entire platform securely in a few different ways. This the default option and routes traffic from the remote machine to the client machine, which allows you to test to websites hidden behind a firewall.

Input validation is a programming technique that ensures only properly formatted data may enter a software system component. An application should check that data is both syntactically and semantically valid in that order before using it in any way including displaying it back to the user. Syntax validity means that the data is in the form that is expected. The application should assume the user is entering a SQL injection payload, and should check that the data entered by the user is exactly four digits in length, and consists only of numbers in addition to utilizing proper query parameterization.
