The recent Heartbleed bug that compromised two-thirds of all websites was a sharp reminder that businesses are vulnerable. The Federation of Small Businesses (FSB) reports that cybercrime costs the UK economy an estimated £27 billion a year. Such attacks not only damage business growth but they also erode customer trust.
Despite the importance of securing both confidential customer and company data, many businesses continually fail to prevent breaches.
