URL Sentry

While surfing the Internet can be a pleasant way to spend your free time, it also involves a certain number of risks that you can be exposed to unless you have a way of preventing them.
Third-party software, such as URL Sentry, can help you protect your computer against cyber threats by allowing you to perform scans on links before accessing them.
Note that this application requires an Internet connection and a supported web browser to run as intended.

Lightweight application that comes with a plain user interface

This application is easy to install, as it does not require you to perform any additional configuration. It comes with a minimalistic, visually unappealing user interface that provides you with simple functions, thus allowing you to understand and access them in an easy manner.
Unfortunately, it does not come with any form of help documentation, therefore preventing you from relying on a user guide in case you get stuck while operating its functions.

Allows you to perform scans on your URLs before accessing them

URL Sentry allows you to perform quick scans on your URLs before actually accessing them, thus preventing you from accessing a malicious address.
You just need to copy the desired link to your clipboard and paste it into the application, so that it can perform a scan on your content. Accessing the application can be done by either clicking its icon in the system tray or by relying on the user-defined key combination.

Does not allow you to access the Settings window from its main interface

Unfortunately, this program does not allow you to access the configuration section from its main window. You can only adjust its parameters by right-clicking its tray icon and selecting the Settings function from the menu.
To sum it up, URL Sentry is a lightweight application that can help you perform scans on URLs before accessing them. However, note that it comes with an outdated user interface, it does not allow you to access the Settings section from the main window and does not include any help manual.
