Essential Eight Compliance for Melbourne AFSL Firm
A Melbourne AFSL-regulated firm engaged CTS to bring its cybersecurity up to the ACSC Essential Eight and to document that compliance for its licensee and auditors. Security had been managed ad-hoc, with no maturity assessment and clear gaps across several of the eight mitigation strategies. CTS assessed the firm's current maturity, delivered a prioritised remediation roadmap, and produced audit-ready documentation aligned to Maturity Level 1.

The challenge
As an AFSL holder, the firm was expected to demonstrate sound cybersecurity, but had no framework, assessment or evidence to show.
- AFSL obligations to maintain and evidence adequate cybersecurity
- Security managed ad-hoc with no reference framework or maturity assessment
- Gaps across MFA, patching, application control and backups
- No documented evidence of controls for the licensee or auditors
- Uncertainty about which risks to address first and to what standard
The CTS roadmap
CTS assessed the firm against the Essential Eight and remediated each strategy to Maturity Level 1, prioritised by risk.
- Conducted an Essential Eight maturity assessment of the current environment
- Produced a prioritised remediation roadmap addressing the highest risks first
- Enforced MFA and conditional access across all accounts
- Automated operating system and application patching through Intune
- Implemented application control and Microsoft Office macro hardening
- Established immutable backups and restricted administrative privileges
Audit-ready documentation
For a regulated firm, the evidence of compliance is as important as the controls themselves.
- A maturity assessment mapping each of the eight strategies to Maturity Level 1
- A control register the firm can present to its licensee and auditors
- An evidence pack documenting configuration and coverage
- A quarterly review cadence to maintain and uplift maturity
The results
The firm achieved a documented, defensible Essential Eight baseline aligned to its AFSL obligations.
- Maturity Level 1 reached across all eight mitigation strategies
- Documented, audit-ready evidence of controls for the licensee
- MFA, patching, application control and backups brought to standard
- A prioritised roadmap for ongoing maturity uplift
- Quarterly governance keeping compliance current
Technologies deployed
Microsoft Entra ID (conditional access and MFA), Microsoft Intune, Microsoft Defender, and immutable backup with restricted administrative privileges.
Frequently asked questions
What does Essential Eight Maturity Level 1 mean?
Maturity Level 1 is the baseline tier of the ACSC Essential Eight, where each of the eight mitigation strategies is implemented to counter common, untargeted attacks. CTS brought this AFSL firm to Maturity Level 1 across all eight strategies and documented the result as audit-ready evidence.
Why do AFSL firms need the Essential Eight?
AFSL holders are expected to maintain and be able to evidence adequate cybersecurity. The Essential Eight provides a recognised framework to structure controls and a clear basis for documentation, making it straightforward to demonstrate a sound security posture to a licensee or auditor.
How long does an Essential Eight uplift take?
After an initial maturity assessment, CTS works through a prioritised roadmap that addresses the highest-risk gaps — typically MFA, patching and admin restriction — first, with the full Maturity Level 1 baseline delivered over several weeks and maintained through quarterly reviews.
