Further Five Cybersecurity Controls

If you’ve already implemented the Essential Eight, your organisation has taken a significant step toward reducing risk. But cyber threats are evolving — and so must your defence.

That’s why the Further Five cybersecurity controls exist: to fill critical gaps that remain even after full Essential Eight compliance. These additional controls are practical, high-impact, and increasingly adopted by mature Australian businesses looking to strengthen their posture.

At Epic IT, we help Perth-based organisations assess, implement, and maintain the Further Five — turning what’s often seen as “advanced security” into manageable, operational protection.

What Are the Further Five?

The Further Five are a recommended set of controls that complement and extend the protections of the Essential Eight. While not part of the original ACSC baseline, they’ve become a recognised part of building real-world cyber resilience — especially for organisations handling sensitive data, working across multiple sites, or pursuing formal compliance or insurance alignment.

The Further Five controls are:

  • Backup Testing and Validation – Ensuring backups aren’t just running, but actually recoverable
  • Security Event Monitoring – Detecting suspicious activity before it causes damage
  • Vulnerability Scanning – Proactively identifying and fixing weak points in your systems
  • Incident Response Planning – Preparing your team to act fast and effectively in a breach
  • Network Segmentation – Limiting how far an attacker can move if they get inside

Each of these adds a critical layer of protection beyond standard endpoint, patching, and user controls.

Epic IT’s Approach

We start by reviewing your current Essential Eight maturity and identifying where your business is most exposed. Then, we guide you through each Further Five control — prioritising based on risk, operational fit, and urgency.

Our local team can:

  • Run and review vulnerability scans
  • Implement backup testing routines
  • Set up log monitoring and alerting
  • Develop a tailored incident response plan
  • Assist with segmenting internal networks across sites or departments

Whether you’re aiming for cyber insurance eligibility, internal governance, or formal frameworks like ISO 27001 — we help you build defences that stand up to scrutiny.
