Essential Eight and Cyber Insurance: What Perth Businesses Need to Know

If you've renewed a cyber insurance policy recently, you've probably noticed the application form asks far more detailed technical questions than it used to. Many of those questions trace directly back to the Essential Eight - and how you answer them can directly affect your premium, your excess, and whether a claim gets paid at all.

Why Insurers Care About the Essential Eight

Cyber insurers have paid out enormous sums on ransomware and business email compromise claims over the past few years. In response, most insurers have tightened their underwriting - moving away from simple tick-box questionnaires toward more specific questions about the controls a business actually has in place.

The Essential Eight gives insurers a ready-made, well-recognised framework to ask those questions against. Even if a policy doesn't explicitly mention "Essential Eight" by name, the questions on the application form will often map closely to it.

The Controls Insurers Ask About Most

Across most cyber insurance applications, a handful of Essential Eight controls come up again and again:

• Multi-factor authentication (MFA) - particularly for email, remote access, and admin accounts. This is now close to a non-negotiable for many insurers.
• Backups - whether backups are regular, tested, and stored separately from your production environment (so ransomware can't reach them too).
• Patching - whether operating systems and applications are kept up to date, and how quickly critical vulnerabilities are addressed.
• Restricted admin privileges - whether administrative access is limited to those who need it, and separated from everyday accounts.
• Email filtering and macro controls - given how many incidents start with a phishing email or malicious attachment.

What Happens If You Fall Short

Answering these questions inaccurately - even unintentionally - can create real problems down the track. If a claim is made and the insurer finds that the controls described on the application weren't actually in place, it can affect the outcome of the claim, not just future premiums.

On the other hand, businesses that can demonstrate strong Essential Eight alignment often see more competitive premiums and fewer exclusions, because they represent a lower risk to underwrite.

Preparing for Your Next Renewal

The best time to address gaps is before the application form lands in your inbox, not while you're filling it out under time pressure. A few months' head start gives you time to:

• Understand exactly where your business sits against each of the eight strategies - our free 2-minute self-assessment is a good starting point.
• Prioritise and budget for the highest-impact gaps - MFA and backups are usually the quickest wins.
• Document what's in place, so you can answer application questions accurately and confidently.

Closing the Gaps Before You Apply

An Essential Eight assessment gives you a clear picture of your current maturity level against each strategy, along with a prioritised roadmap. That roadmap can then directly inform your renewal timeline - so you're not just hoping you'll qualify for better terms, you know where you stand and what's already been addressed.
