Layer-7 analysis involves inspecting network traffic at the application layer to
understand the specific actions being performed, such as which files are being accessed
or which commands are being sent to a programmable logic controller. This provides
much deeper visibility than traditional firewall logging, which only sees the source
and destination at the network layer. By monitoring these granular details in real
time, security teams can detect subtle anomalies that may indicate a sophisticated
attack in progress. Our [evolution guide](https://www.agilicus.com/from-tunnels-to-zero-trust-the-evolution-of-industrial-remote-access/)
explains this shift in visibility.
