Network security is a fundamental, yet essential foundation of any security infrastructure and often used to define the initial layers of a defence-in-depth security strategy. However, network security is often limited to perimeter and network layer protection, as opposed to considering all network elements including management of the application-layer.

Silversands is able to design and implement solutions that allow you to precisely control network security and ensure your company is able to reduce vulnerabilities to mitigate risks to an appropriate level.

 These security controls include protection at the network-layer using stateful packet filtering firewall and VPN technology with Juniper SSG security appliances. More importantly, crucial protection is required at the application-layer using Microsoft Forefront Threat Management Gateway or Microsoft Unified Access Gateway; with either provisioned using traditional server hardware, Hyper-V/VMware virtualisation platforms or using dedicated Celestix MSA/WSA appliances.
