Built-in Web based User interface

GateSentry comes with its own web based interface which is powered by React and can be easily viewed via any modern desktop/mobile browser.

HTTPS Filtering

GateSentry does support Https content filtering by doing a MITM attack on your secure traffic. If you don't need this feature it can be disabled via GateSentry's administration panel.

Built-in User authentication system

GateSentry comes with a built in user authentication system where you can add more users/delete users, disable their internet access. If not required on your network you can disable the user authentication system too.

Time based Internet Access

Time based Internet access allows you to set times during which internet access would be disabled on your network.

Content type blocking

Content type blocking allows you to block specific file types on your network. Want to disable images? simply add the mime "image/png" and "image/jpeg" to GateSentry.

Data Consumption Statistics

If the user based authentication system is enabled GateSentry shows the amount of data consumed by each user on your network.

Remotely Disable User access

Access for network users can be easily enabled or disabled with a single click from the User Management Panel.
