MailScan 4 is world's first 'Real-Time', Content Security software that performs content filtering and virus scanning. It provides complete and secure messaging solutions for e-business.

With MailScan's revolutionary technology that creates a layer, termed as Microworld WinSock Layer (MWL), any traffic that comes into a company's network is scanned for security violations. If any violation or threat is detected, MailScan immediately warns the network administrator and the sender of the possible actions.
