Frequently asked questions

From risk assessment to rapid response - we’re with you every step of the way.

What is a cyber security risk assessment?

A cyber security risk assessment is a structured process used to identify, analyse and evaluate potential threats to your systems, data and operations. It helps you understand where you're exposed and what actions to take to reduce risk.

Why does my business need a risk assessment?

Risk assessments help you make informed decisions about security investments and compliance. They show you where your biggest risks are, what’s acceptable, and where you need better controls to protect your organisation.

What standards do Bastion’s risk assessments follow?

Our assessments align with recognised frameworks like ISO 31000, ISO 27005 and AS/NZS standards. We adapt our approach to your environment while maintaining consistency, transparency and clear documentation.

How long does a risk assessment take?

Most assessments can be completed in 2 to 4 weeks, depending on the complexity of your systems and the number of stakeholders involved. We’ll give you a clear timeline and delivery plan at the start.

Will the risk assessment help with compliance?

Yes. Our assessments are designed to support compliance with frameworks such as ISO 27001, PCI DSS and NIST CSF. You’ll get clear documentation that can be used for audits, board reporting and certification readiness.
