There’s no simple answer because a judgement will be dependent on a number of factors, such as the size of your business, its business activities, the level of IT security and sensitivity of the data you hold.
Our cyber insurance partners can provide sample loss scenario reports, offering guidance on the value of different types of cyber claims for a business of your size and industry. These are a good starting point for negotiations around how much cover you need.
Some cyber insurance is better than none, so if budgets are tight at least consider entry level cover.
