Portal application

Portal application

(also web portal, online portal)

Portal application definition

A portal application aggregates information from various sources and presents them in a user-friendly and customizable interface. It eliminates the need for users to navigate through multiple websites or applications. Instead, they get a single access point, typically via a web browser. So it’s far easier for them to find the information they need. However, portal applications often contain sensitive data and integrate with other critical systems, making them a target for cybercriminals. For instance, bad actors may attempt to exploit vulnerabilities or gain unauthorized access to the portal to steal data, disrupt services, or launch service attacks on other connected systems.
