How do I prevent a malicious insider threat?

1:3 data breaches are due to malicious trusted insiders.

90% of senior managers are worried about the insider threat.


A malicious insider’s system access and knowledge of business processes can make them hard to detect. But there are practices you can put in place to reduce the risk of a malicious insider in your organisation.

Business processes: Personnel security (PERSEC)

For all employees, irrespective of their system access, pre-employment and background checks are a good first step. Be clear with new starters on how you can and will check their background and suitability to have access to PII or commercially sensitive information. You should also consider ongoing, periodic checks to ensure that you employees’ situations haven’t changed to enhance your organisations security posture, culture and overall contentment of your staff. These steps will help mitigate the insider threat. The more integrity and transparency you have in your work environment, the harder it is to act dishonestly. Additionally, happy, valued and challenged staff members are less likely to act to harm your organisation.

Thinking of selling your business?

Then know that a data breach in your recent past degrades your intangible assets – goodwill and reputation – by as much as 20% from a like-for-like company that has not had a breach. You can enhance your business’s valuation and reputation by having your staff’s background reviewed.
