Essential Eight Compliance Services
We'll work with your team to assess your Essential Eight compliance, establish a baseline against the required standard and work towards accreditation where required.
We’ll help you achieve IT security through the assessment of your organisation's Essential 8 compliance.
The Essential 8 is a suite of strategies developed by the Australian Cyber Security Centre (ACSC), designed to mitigate the most common cyber threats that lead to security incidents and disruptions. Tesserent's Essential 8 compliance services encompass a broad spectrum of cybersecurity measures, applicable across various networks, systems, and applications, with a particular focus on Microsoft Windows-based networks. These services are not just about implementing security measures; they are about building a robust cybersecurity framework that enhances the protection of critical information and data.

Understanding the Essential Eight
The Essential 8 Maturity Model
The Essential 8 is a set of mitigation strategies, developed and maintained by the Australian Cyber Security Centre (ACSC), that are designed to help organisations of all sizes protect themselves from the online threats that are recognised as being the root cause of most intrusion events and unplanned outages.
These cybersecurity advisory services can be applied across a broad spectrum of networks, systems and applications, from local installations through to cloud and other online services - although it is largely targeted at Microsoft Windows based networks. Essential 8 provides the building blocks of a robust cybersecurity strategy.
What does the Essential 8 focus on
Each element of the Essential 8 focuses on a different aspect of cybersecurity strategy: the eight core elements identified as the most common areas resulting in cybersecurity incidents. The Essential Eight provide information and data management strategies, and guidance on secure configuration, to protect the confidentiality, integrity and availability of an organisation's critical information and data. The Essential 8 focus areas are:
Application control
Patch applications
Configure Microsoft Office macro settings
User application hardening
Restrict administrative privileges
Patch operating systems
Multi-factor authentication
Regular backups
Essential 8: The Key to Cybersecurity Excellence
Navigating the ever-evolving digital landscape can feel like venturing into a dense forest without a map. Cyber threats lurk behind every tree, and one wrong step can compromise systems. But fear not! There's a guiding light for Australian organisations: the Essential 8. Developed by the Australian Cyber Security Centre, this set of essential mitigation strategies offers a blueprint to significantly enhance an organisation's security posture and reduce the risk of cybersecurity incidents.
Mitigation Strategies of Essential 8 cyber security
When it comes to combating cyber threats, generic solutions don’t cut it. Recognising this, the Australian Cyber Security Centre has developed prioritised mitigation strategies tailored to tackle various cyber threats effectively. This guidance was born from a comprehensive assessment of prevalent cyber security incidents. The result? The Essential 8 - a robust set of strategies to mitigate cyber security incidents.
Application Whitelisting
Application control ensures that only approved applications run within systems. This reduces the risk of malicious code infiltrating the organisational network.
Patching Applications and Operating Systems
Regularly updating your applications and operating systems is like fixing the cracks in your house’s walls. By patching applications, organisations protect themselves from known security vulnerabilities.
Configuring Microsoft Office Macro Settings
Microsoft Office is synonymous with daily business operations. But malicious actors often exploit Microsoft Office macros. Tweaking the macro settings restricts the execution of potentially harmful code.
Application Hardening
This is about fortifying your defenses. User application hardening limits the functions of applications, making it harder for adversaries to exploit vulnerabilities.
Restricting Administrative Privileges
It's vital to ensure that only trusted individuals have access to privileged accounts, reducing the risk of malicious internal actions.
Multi-Factor Authentication
By implementing multi-factor authentication, organisations add an extra layer of protection, ensuring that even if passwords are compromised, malicious actors can't easily gain access.
Daily Backups
Daily backups ensure that vital data remains secure and available, even if primary systems are compromised.
Web Content Filtering
Web content filtering screens out malicious web browsers and pop-ups, ensuring that users don't inadvertently welcome cyber threats into the system.
As well as providing guidance on what Australian organisations should do to reduce the risk of a cyber-attack, and how to minimise the impact should a threat actor breach your defences, the ACSC has created the Essential 8 Maturity Model to assist organisations in assessing how well they are implementing the mitigation strategies.
Level 0: At this level, organisations exhibit weaknesses in their cybersecurity posture that can be exploited by threat actors using common tools and methods.
Level 1: Organisations at this level have basic protections in place that help prevent cyber criminals and other threat actors, using common tools and methods, to break into systems.
Level 2: Organisations that achieve this level of maturity have strategies in place to mitigate a variety of sophisticated security attacks that seek to exploit elevated user privileges and other potential weaknesses such as credential harvesting.
Level 3: The highest level of maturity: these organisations implement a range of tools such as specific application controls, workstation logging and monitoring to ensure anomalous activity can be quickly detected and investigated and they undertake rapid patching of known vulnerabilities.
