The internet has become a prime communications and collaboration channel for organisations in all walks of life and its importance is growing as Web 2.0 applications such as wikis and blogs are gaining in importance. However, this has not been lost on hackers, who look to intercept communications or plant malware in web-based applications in an attempt to steal the information that is being communicated, as this information is financially valuable to them. Because of this, the web is now a prime vector of attack, but the threats being seen are also increasingly complex and sophisticated and are more targeted at specific individuals or organisations than ever before. Attackers are also using blended mechanisms in an attempt to make their payloads more successful, often using a combination of web and email.
In the face of these more complex threats, traditional signature-based technologies struggle to keep up. Organisations must also play a game of catch up to keep all devices protected against the latest threats through constant updates. Many organisations are taking a look at their existing investments, especially in the area of email security. A viable alternative is to subscribe to security services based in the cloud and to look for a provider that offers a combination of both email and web security to protect themselves from today
