Developing and sustaining a proactive security culture can help you to mitigate against a range of threats that could cause operational, reputational or financial damage to your organisation. It is an essential component of any protective security regime.

If used in the right way, your staff, guard force, contractors, visitors, suppliers and the general public can be a huge force multiplier, at no or low cost, in strengthening your resilience to security threats and reducing your vulnerability to attack.

Security Culture Tool

When you have an effective security culture, your people become your biggest asset. Getting your culture right will ensure that your workforce are security-conscious and think about how to protect the assets and systems that they have access to.

There is no single ‘right’ security culture; what is effective for your organisation will depend on who you are, what you do, the threats that you face and your other strategic priorities and pressures.

NPSA’s Security Culture Tool is a free, online self-service tool designed to help you understand your organisation's security culture and how to enhance it.
