Application-layer gateways
Tangent
Tangent application-layer gateways (ALG) are the major line of defence to secure your local network. As the evolution of a firewall, they separate the local network from the external world.
The combination of a Tangent application-layer gateway and a Secant gateway constitutes a packet-filter-ALG-packet-filter (PAP) structure: the so-called security gateway — it is the basis for networks that can handle classified data like the German 'VS-Nur für den Dienstgebrauch' (VS-NfD) standard.
