From TalkTalk to Ashley Madison, major data breaches have scarcely been out of the headlines for a moment this year.

2015 has been the year when hacks really went through the roof, with millions of people having had their private data stolen in the UK alone and national governments scrambling to combat the growing threat of cyber attacks.

Torben Andersen, chief commercial officer of SMS Passcode, said that organisations need to begin “thinking more laterally about security”:

This escalation in cyber attacks is only set to get worse. Whether it’s criminal gangs, teenage IT geeks, terrorists or, increasingly, Government sponsored organisations, the cyber threat is constantly evolving as are hackers’ methods.
