About The Customer
National Australia Bank (NAB) is one of Australia’s “Big Four” financial institutions, serving consumer and commercial interests in Australia, New Zealand, and across Asia. With over nine million customers, NAB is the largest business bank in Australia and a national icon with a history spanning 160 years. The bank's IT organization supports business operations for more than 1500 branches, and its IT team is led by Steve Day, the Executive for Enterprise Technology. NAB has a revenue of USD$12B40 and employs 35,000 people across eight countries and 1600 locations.
The Challenge
National Australia Bank (NAB), one of Australia’s “Big Four” financial institutions, faced a significant challenge in balancing the convenience of online transactions with the need for personal, direct engagement for larger transactions. The bank was also grappling with the strict data-privacy requirements, low risk tolerance, and regulatory constraints typical of the financial services industry. In the mid-2010s, NAB recognized the potential value of migrating to the cloud, particularly for strengthening its security posture. However, the transition was not without its challenges. In early 2020, the COVID-19 pandemic hit, leading to a surge in customer call volumes and necessitating a shift to remote work for the safety of NAB's employees. This sudden change posed a practical challenge, as not all of NAB's employees were equipped to work remotely.
The Solution
To address these challenges, NAB invested in Zscaler Internet Access (ZIA), implementing local internet breakouts for users and leveraging ZIA’s Cloud Sandbox security technology. The bank's shift to the cloud was driven by security priorities, with a focus on achieving a Zero Trust environment. When the pandemic hit, NAB had to quickly scale up its operations to accommodate higher customer call volumes and enable remote work for its employees. The bank realized that it could not scale up its existing VPN solution rapidly due to the time and cost involved in procuring legacy connectivity hardware. Instead, NAB opted for an accelerated rollout of Zscaler Private Access (ZPA), shifting to a remote-access model and deploying ZPA for thousands of employees. This enabled them to access corporate resources from remote locations, facilitating a smooth transition to remote work.

Real-time In-vehicle Monitoring
The telematic solution provides this vital premium-adjusting information. The solution also helps detect and deter vehicle or trailer theft – as soon as a theft occurs, monitoring personnel can alert the appropriate authorities, providing an exact location.“With more and more insurance companies and major fleet operators interested in monitoring driver behaviour on the grounds of road safety, efficient logistics and costs, the market for this type of device and associated e-business services is growing rapidly within Italy and the rest of Europe,” says Franco.“The insurance companies are especially interested in the pay-per-use and pay-as-you-drive applications while other organisations employ the technology for road user charging.”“One million vehicles in Italy currently carry such devices and forecasts indicate that the European market will increase tenfold by 2014.However, for our technology to work effectively, we needed a highly reliable wireless data network to carry the information between the vehicles and monitoring stations.”

Smooth Transition to Energy Savings
The building was equipped with four end-of-life Trane water cooled chillers, located in the basement. Johnson Controls installed four York water cooled centrifugal chillers with unit mounted variable speed drives and a total installed cooling capacity of 6,8 MW. Each chiller has a capacity of 1,6 MW (variable to 1.9MW depending upon condenser water temperatures). Johnson Controls needed to design the equipment in such way that it would fit the dimensional constraints of the existing plant area and plant access route but also the specific performance requirements of the client. Morgan Stanley required the chiller plant to match the building load profile, turn down to match the low load requirement when needed and provide an improvement in the Energy Efficiency Ratio across the entire operating range. Other requirements were a reduction in the chiller noise level to improve the working environment in the plant room and a wide operating envelope coupled with intelligent controls to allow possible variation in both flow rate and temperature. The latter was needed to leverage increased capacity from a reduced number of machines during the different installation phases and allow future enhancement to a variable primary flow system.

Automated Pallet Labeling Solution for SPR Packaging
SPR Packaging, an American supplier of packaging solutions, was in search of an automated pallet labeling solution that could meet their immediate and future needs. They aimed to equip their lines with automatic printer applicators, but also required a solution that could interface with their accounting software. The challenge was to find a system that could read a 2D code on pallets at the stretch wrapper, track the pallet, and flag any pallets with unread barcodes for inspection. The pallets could be single or double stacked, and the system needed to be able to differentiate between the two. SPR Packaging sought a system integrator with extensive experience in advanced printing and tracking solutions to provide a complete traceability system.

Transforming insurance pricing while improving driver safety
The Internet of Things (IoT) is revolutionizing the car insurance industry on a scale not seen since the introduction of the car itself. For decades, premiums have been calculated using proxy-based risk assessment models and historical data. Today, a growing number of innovative companies such as Quebec-based Industrielle Alliance are moving to usage-based insurance (UBI) models, driven by the advancement of telematics technologies and smart tracking devices.
