Network Security

Our layered security solutions combine multiple security controls into an effective approach to protecting key resources and data.

The Layer 3 approach to security looks at the entire network as a whole including edge devices (firewalls, routers, web servers, anything with public access), endpoints such as workstations along devices connected to the network including mobile phones to create an effective plan for security management.
