Essential Eight

Secure by strategy, strengthen through uplift

Engage with Catalyst for end-to-end Essential Eight services that benchmark, uplift, and mature your cyber defences.

Our experienced E8 consultants assess your environment against the ACSC's Essential Eight maturity model, identify gaps, and implement practical, scalable security controls. We deliver clear insights, tailored remediation plans, and measurable improvements to help you build resilience and meet compliance with confidence.

Get Started

What We Assess

Our Essential Eight security assessments provide a detailed technical review of your environment measured by technical simulation and validation activities coupled with documentation and policy review and interviews.

The ACSC's recommended Essential Eight strategies to mitigate cyber security incidents. By aiming for your desired maturity level (based on industry or requirement), we help you build cyber resilience and harden key systems.

Application control

โ–ผ

Catalyst evaluates how effectively your organisation prevents unapproved or malicious software from executing across your environment. We assess your application whitelisting implementation, policy effectiveness, and coverage across all systems to ensure only trusted applications can run, providing a critical first line of defence against malware and unauthorised software.
