With the Internet constantly expanding, and outside the jurisdiction of any one authority, there is an ever-present danger from people who abuse its capabilities. Some publish potentially offensive content like pornography and racist material, others send masses of junk mail, or spam, while malicious hackers continue to write viruses, disrupt communications and gain unauthorised access to systems. There has never been a greater need to ensure security and safety for network users, especially in education where most users are children.
Although no single product or service can guarantee total protection, Atomwide has assembled a range of leading solutions that combine to form an effective defence against most Internet-based threats. Among these is the renowned EmailSystems service that checks email for viruses, spam and pornography.

For networks of all sizes, the protection of data is a key issue. On a simple LAN, enforcing file permissions and account policies may offer enough security, but more complex scenarios often arise, even within a single site. For example, a school may wish to keep its curriculum and administrative networks separate using two sets of equipment, or virtual LANs. If restricted communications between these networks subsequently becomes necessary, a router could be used to create a secure and controlled bridge.
Beyond this, if a wide area network link is added, protection against intruders may be provided by a hardware firewall, such as a Cisco PIX device.
