Essential Eight: Compliance as a Managed Service

The Essential Eight is the Australian Cyber Security Centre's (ACSC) baseline framework of eight mitigation strategies that protect organisations against the most common cyber threats. Every Australian organisation should implement the Essential Eight, and government agencies at Commonwealth and state level are mandated to comply.

Most organisations struggle with Essential Eight because it requires sustained operational effort across multiple technology domains. It is not a project you complete once. It requires continuous monitoring, patching, policy enforcement, and maturity uplift. Evocate delivers Essential Eight compliance as a managed service, using the Microsoft security stack your organisation already licenses to implement, monitor, and report on all eight strategies.

Essential Eight mitigation strategies framework

What are the Essential Eight mitigation strategies?

The eight strategies are: application control, patch applications, configure Microsoft Office macro settings, user application hardening, restrict administrative privileges, patch operating systems, multi factor authentication, and regular backups. Each strategy addresses a specific attack vector. Together they form a baseline that prevents the majority of commodity cyber attacks that target Australian organisations. The ACSC defines four maturity levels (0 to 3) for each strategy. Level 0 means the strategy is not implemented. Level 1 is partly aligned. Level 2 is mostly aligned with consistent implementation. Level 3 is fully aligned with all controls enforced across the environment. Most organisations should target Maturity Level 2 as a minimum, with government agencies required to reach Level 2 or 3 depending on their classification.

Essential Eight managed service delivery

How does Evocate deliver Essential Eight as a managed service?

We use the Microsoft security stack that most organisations already pay for through Microsoft 365 E3 or E5 licensing. Microsoft Defender Application Control and AppLocker handle application control. Microsoft Intune manages patching, macro settings, and user application hardening. Microsoft Entra ID enforces administrative privilege restrictions and multi factor authentication. Microsoft Azure Backup and SharePoint provide backup and recovery. Our security engineers configure these tools, monitor compliance continuously, investigate policy violations, coordinate remediation, and report maturity status monthly. You get Essential Eight compliance without hiring security specialists or purchasing additional products.

Microsoft security stack for Essential Eight

Do we need additional software beyond Microsoft 365?

In most cases, no. Microsoft 365 E5 licensing includes Microsoft Defender for Endpoint, Intune, Entra ID P2, and the security tools needed to implement all eight strategies. E3 organisations may need Defender for Endpoint Plan 2 and Intune Plan 2 as add ons for full coverage. We assess your current licensing during onboarding and recommend the most cost effective configuration. We do not sell third party security products. If the Microsoft stack covers the requirement (and for Essential Eight it does), we use what you already have rather than adding complexity and cost.

Essential Eight maturity level targeting

What maturity level should our organisation target?

The appropriate target depends on your industry, regulatory obligations, and threat profile. Government agencies at Commonwealth level are mandated to reach Maturity Level 2 minimum, with many targeting Level 3. Defence industry organisations under DISP should target Level 2 or higher. Private sector organisations handling sensitive data should aim for Level 2, while those with lower risk profiles can start with Level 1 and progress over time. We conduct an initial maturity assessment to establish your baseline across all eight strategies, then build a roadmap to your target level with realistic timelines and effort estimates.

Prevent malware execution

Application control and macro restrictions stop ransomware and malware from running even if a user clicks a malicious link or opens a compromised attachment.

Limit attack impact

Restricted administrative privileges and user application hardening contain breaches to a single system rather than allowing attackers to move across your environment.

Close vulnerability windows

Patching applications and operating systems within defined timeframes eliminates the known vulnerabilities that attackers exploit most frequently.

Recover from incidents

Tested, verified backups ensure your organisation can recover from ransomware or destructive attacks without paying ransoms or losing data permanently.

Application Control (Strategy 1)

Prevent unauthorised applications from executing on your systems. This is the most effective single strategy against malware and ransomware.

Microsoft Defender Application Control (WDAC) policy design and deployment
AppLocker rules for legacy environments requiring compatibility
Application whitelist management and exception handling
Blocked execution monitoring and policy violation investigation
Regular policy review as business application needs change

Patch Applications and Operating Systems (Strategies 2 and 6)

Close known vulnerabilities by patching applications within 48 hours for critical exploits and operating systems within defined timeframes. Unpatched systems are the most common entry point for attackers.

Microsoft Intune patch compliance monitoring across all managed devices
Critical patch deployment within 48 hours of vendor release
Application inventory and version tracking
Compliance reporting and remediation coordination for non compliant devices
Emergency patching procedures for actively exploited zero day vulnerabilities

Microsoft Office Macros and Application Hardening (Strategies 3 and 4)

Restrict macro execution to trusted sources and harden user applications against common attack techniques including browser exploits, malicious ads, and untrusted code execution.

Office macro security policies via Intune (block macros from internet, restrict to signed)
Attack Surface Reduction (ASR) rules deployment and tuning
Browser hardening (block Flash, Java, ads on untrusted sites)
PDF reader security configuration
PowerShell constrained language mode enforcement

Administrative Privileges (Strategy 5)

Restrict administrative access to dedicated accounts, enforce just in time elevation, and audit privilege usage to prevent attackers from gaining domain level access.

Privileged Identity Management (PIM) configuration in Entra ID
Administrative tiering separation (user accounts vs admin accounts)
Just in time elevation with approval workflows and time limits
Administrative access audit and unused privilege removal
Break glass account management and regular testing

Multi Factor Authentication (Strategy 7)

Enforce phishing resistant MFA for all users and all administrative access. MFA prevents 99.9% of credential based attacks according to Microsoft security research.

Entra ID Conditional Access policies for MFA enforcement
Phishing resistant methods (FIDO2 keys, Windows Hello, certificate based)
Legacy authentication protocol blocking
MFA gap reporting and remediation for non compliant accounts
Emergency access procedures (break glass) that maintain MFA policy

Regular Backups (Strategy 8)

Maintain tested, verified backups that enable recovery from ransomware, destructive attacks, or accidental data loss. Backups must be protected from the same threats as production data.

Backup configuration audit (Azure Backup, SharePoint retention, Exchange archiving)
Recovery point objective (RPO) and recovery time objective (RTO) validation
Quarterly recovery testing with documented results
Backup isolation from production environment (immutable storage, air gapped copies)
Backup monitoring and failure alerting

Compliance without headcount

Implementing and maintaining Essential Eight requires security engineering skills that are scarce and expensive in Australia. Our managed service delivers compliance for less than one senior security hire.

Continuous rather than point in time

Annual assessments show a snapshot. Managed compliance means your maturity level is maintained every day, not just on audit day. Drift is detected and corrected before it creates risk.

Board ready reporting

Monthly reports show maturity level per strategy, progress toward targets, gaps requiring attention, and comparison against ACSC benchmarks. Your board and auditors get evidence without interpretation.

Frequently Asked Questions

The Essential Eight is a set of eight cyber security mitigation strategies published by the Australian Cyber Security Centre (ACSC). The strategies are application control, patch applications, configure Microsoft Office macro settings, user application hardening, restrict administrative privileges, patch operating systems, multi factor authentication, and regular backups. Together they prevent the majority of commodity cyber attacks targeting Australian organisations.

Essential Eight is mandatory for non corporate Commonwealth entities (Australian Government agencies). State governments have varying requirements. For private sector organisations it is strongly recommended by the ACSC but not legally mandated, though many clients and partners require evidence of Essential Eight compliance as part of vendor security assessments.

The ACSC defines four maturity levels. Level 0 means the strategy is not implemented. Level 1 is partly aligned with basic implementation. Level 2 is mostly aligned with consistent implementation across the environment. Level 3 is fully aligned with all controls enforced. Most organisations should target Level 2 minimum, with government agencies often mandated at Level 2 or 3.

For organisations starting at Level 0 or 1, reaching Level 2 across all eight strategies typically takes 3 to 6 months with dedicated effort. The timeline depends on environment complexity, existing Microsoft tool deployment, and how many legacy systems require accommodation. Evocate builds a realistic roadmap during the initial assessment.

E5 provides the most complete toolset (Defender for Endpoint P2, Intune, Entra ID P2, Purview) and is recommended. However, E3 organisations can achieve compliance with Defender for Endpoint P2 and Intune as add on licences. We assess your current licensing and recommend the most cost effective configuration that meets your target maturity level.

The Essential Eight is a subset of the Information Security Manual (ISM) published by the ACSC. The ISM contains hundreds of controls across multiple domains. The Essential Eight represents the eight most effective strategies from the ISM for preventing cyber attacks. Compliance with Essential Eight contributes to broader ISM compliance but does not cover all ISM requirements.

Yes. We conduct formal Essential Eight maturity assessments that evaluate each strategy against ACSC criteria, document your current maturity level with evidence, identify gaps, and produce a remediation roadmap. The assessment typically takes 2 to 3 weeks and results in a report suitable for presenting to boards, auditors, or government stakeholders.

Monthly reports show maturity level per strategy, changes since last report, policy violations and remediation actions, patching compliance percentages, MFA coverage metrics, and progress toward target maturity. Quarterly reports include trend analysis and recommendations for maturity uplift initiatives.
