Bastion is an Application Protocol Firewall that acts as a trusted intermediary for all messaging traffic between internal and external networks or networks that do not share a common level of trust.
Certified to EAL4 standard, it stops virus, malware and hacker attacks and offers a protected environment in which additional message screening can be applied. It is normally installed in conjunction with various components of the DeepSecure advanced content security solution.
Bastion is a key component in connecting sensitive Government networks and works on SMTP and X.400 messaging traffic, SNMP management traffic and X.525 directory replication traffic.
DeepSecure is an advanced content checking and policy enforcement system which offers protection against the deliberate or accidental release of sensitive information to unauthorised people within the most stringent security environments. This includes checking encrypted or signed messages.
In addition to enjoying the protection of Bastion's EAL4 evaluation for network separation, DeepSecure's Policy Server is separately evaluated to EAL4 for the application and enforcement of policy through the ClearPoint management interface.
Our content security technology can also be applied as a stand-alone package, DeepSecure Lite, in closed environments where firewall protection is provided at the network security layer or within environments having low impact levels.
