The government's Cyber Governance Health Check makes for stark reading.

It's full of interesting information, but most alarming is that a quarter of large firms experience a cyber breach at least once a month, while two-thirds have been hit at least once in the past 12 months.

With a cost associated to each breach, the business case for investing in stronger preventative cyber security is becoming clearer.

There's an interesting debate in cyber security circles as to whether companies should simply accept they'll be breached at some stage, and focus efforts on speed of response. 

While speed of response is undoubtedly important, it shouldn't come at the expense of preventative methods that stop attacks pre-execution.
