As companies face a rising tide of cyber attacks, a new approach to email defence developed by cybersecurity company Darktrace uses our own ability to fight off external threats and replicates this 'immune system' approach in the digital world.

Traditional email security vendors try to adapt with newer technologies like sandboxes, which run suspicious attachments in a controlled environment to see what they do.

The struggle to spot malicious emails is compounded by another problem: old-school email scanning tools tend to get only one shot at catching phishing email and spam.

When applied to cybersecurity, this approach to AI spots correlations in new data, clustering it into patterns that give it a sense of normal digital behaviour and email trends.

Unlike traditional email security gateways, the tool doesn't sit inline, interpreting emails before passing them through.
