Why is my spam in colour?
Today one out of four emails on the internet is an image spam message. This is not because spammers have just realised the marketing benefits of captive colours. Instead, this is because the spammers have identified a weakness in many anti-spam systems and are moving diligently to maximise this opportunity by fully exploiting this weakness.

Why is your network firewall falling short?
Your network is secure, your servers are safe, and you’ve done everything to protect your network, corporate assets and intellectual property. You have a network firewall, so your perimeter is secure. Your network devices and servers are only accessible through your corporate VPN via two-factor authentication, and all external ports are blocked to non-authenticated traffic.

Why IPS won't break your network

It is, by far, the biggest and swankiest event by which excellence in all things IT

Why should anti-virus products employ heuristic detection?
Once upon a time, in a galaxy not so far away, there were only a few computer viruses. Little more than a curiosity to most, they were relatively rare, slow spreading and in general, more of a mythological threat than a real one. The initial anti-virus products that were created to deal with these were perfectly adequate; updated once a month or so, the customers could be fairly sure that they would be protected. Fast-forward to today’s interconnected and always-on world, and the scale of the problem is orders of magnitude above where it was back in those early days.
