IT/OT network security review

Restructuring network security.
Reducing the cost of operating it.

Quokka’s review helped Urban Utilities reshape network security across IT and OT and achieve substantial cost savings.

Urban Utilities

One review across
two operating environments.

Urban Utilities needed to consider the structure and cost of security across corporate IT and the systems supporting water and wastewater services. Individual firewall decisions needed to make sense within that wider estate.

Architecture, policy
and utilisation together.

Quokka reviewed the Check Point and Palo Alto Networks estate, including firewall placement, configuration and use. We connected those findings to a target security architecture and an optimisation plan.

From evidence to an investment decision

Make the structure and cost
of security part of the same decision.

Architecture & placement

Check Point and Palo Alto Networks across IT and OT.

Restructure the estate

A target state with centralised policy control and a resilient edge.

Policy & configuration

How the existing security controls were configured and used.

Align the security model

Consider corporate and operational requirements together.

Utilisation & operating cost

The cost and use of the existing platforms.

Prioritise the changes

Consolidation, decommissioning and platform uplift.

Identified opportunity

$1M+

Potential operating expenditure savings identified in the optimisation plan.

A practical basis
for restructuring.

The review informed changes across the network security estate. Urban Utilities achieved substantial cost savings through the restructure.

The $1M+ figure describes the identified opportunity, not an audited realised or annual saving.

The work behind the outcome

From individual appliances
to the wider operating model.

The value of the review came from connecting technical evidence to decisions about architecture and expenditure across both environments.

Review architecture, policy and use

Review the Check Point and Palo Alto Networks estate across IT and OT, including firewall placement, policy configuration and utilisation.

Define the target security model

Develop a target state with centralised policy control and a resilient edge design, supporting Urban Utilities’ decisions about the structure of its IT and OT environment.

Identify the cost of keeping the existing estate

Build an optimisation plan around consolidation, decommissioning and platform uplift. The plan identified more than $1 million in potential operating expenditure savings.
