For most Australian organisations, the question is no longer whether Zero Trust is the right security model, but how effectively it is operating in practice. Identity controls, conditional access and segmentation can reduce implicit trust, but their effectiveness depends on organisations having sufficient visibility to identify when access, behaviour or system activity moves outside what is expected.

This aligns closely with the Australian Signals Directorate’s (ASD) approach to modern defensible architecture. ASD’s Foundations for Modern Defensible Architecture brings Zero Trust together with secure-by-design principles and places continuous and actionable monitoring alongside capabilities such as contextual authorisation, reliable asset inventory and resilient networks. This is where monitoring becomes important. Organisations need visibility into what users, devices and systems are doing. Continuous monitoring helps security teams recognise when something changes or looks unusual so potential security issues can be investigated, avoiding any damage or harm.

Splunk helps organisation collect and analyse information from across their IT and security environments. Splunk provides direct integration and guidance and aligns its data analytics SIEM platforms with Australian Signal Directorate frameworks. These guidance areas include: 

  • Zero Trust & Essential Eight Alignment 
  • ASD Cyber Threat Intelligence Sharing (CTIS) Plug-in 
  • Australian Government Compliance 

This brings information from different technologies together, providing a complete organisation environment view. This can look like Splunk providing visibility across areas including identities, devices, networks, applications and data. Its technologies can analyse this information and help identify activity that moves outside expected behaviour.

The visibility is important because Zero Trust isn’t a single product that an organisation simply installs. It’s a security approach that relies on information from across the environment to help make better security decisions.

Zero Trust is not something that is implemented once and forgotten. Networks change, new users and devices are added, along with application movements between on-premises and cloud environments. Continuous monitoring helps maintain visibility as those environments change.

Outcomex provides managed services covering complex network, data centre and security environments across on-premises and cloud infrastructure. Its managed services include proactive monitoring, operational support and access to specialist engineering capabilities.

Outcomex also provides managed security capabilities through its Security Operations Centre, which monitors customer IT environments around the clock to identify and respond to security threats.

Bringing these capabilities together allows organisations to take Zero Trust beyond the initial design and implementation stage and make monitoring part of their ongoing security.

Zero Trust starts with a simple principle: don’t automatically trust access just because it comes from a familiar user, device or location. For this approach to work effectively, organisations need visibility into what’s happening across their environment.

Spunk provides the data, monitoring and analytics capabilities that can support that visibility, while Outcomex brings broader experiences across cyber-security, infrastructure, implementation and managed services.
