Grant Thornton increases cyber security 

Grant Thornton says it's increased its levels of cyber security in order to protect clients' personal data.

It's reviewed existing digital security - including hardware, software, accessibility and data storage - as well as implementing new training measures to combat phishing. 

The company says policy had to be updated and revised to take into account the changing nature and sophistication of threats of cyber-attacks which cost UK businesses £34 billion in 2015.
