The Challenge
Sainsbury’s, a leading UK retailer, faced several challenges in its tech security department. The company operates in a 'cloud first' environment, which is crucial for scalability during peak seasons. However, this approach led to incomplete visibility of cloud services, risk of sensitive data loss and non-compliance, restricted Data Loss Prevention (DLP) capabilities, exposure to threats, and lack of consistent policy enforcement. The company needed to ensure visibility across a complex web of cloud services used both internally and with partners. The Data Protection Officer role within Sainsbury’s Data Governance team relied on the insight and controls that the Security team owns. The company handles a lot of data, governed by a range of regulations, making strict adherence to best practice for data governance critical.
About The Customer
Sainsbury’s is one of the UK’s leading retailers across food, clothing, general merchandise and financial services. The company has been trading for 150 years and is one of the best known and loved retail brands in the country. Sainsbury’s Tech Security team is responsible for defining and delivering the technology security strategy and roadmap across all of Sainsbury’s brands and channels, including Argos, Tu clothing, Nectar loyalty, Habitat and Sainsbury’s Bank, as well the core grocery business. The team works in partnership with the CTOs of all of Sainsbury’s business areas to support the tooling, processes and resourcing across three outcome areas: Protecting data, Protecting systems, and Meeting regulatory commitments. Mun Valiji is Chief Information Security Officer (CISO) at Sainsbury’s and works at a peer level with the business CTOs, reporting directly to the Board.
The Solution
Sainsbury’s implemented Netskope, a cloud-native platform that maps billions of transactions, enabling Sainsbury’s to understand user activity across tens of thousands of SaaS and IaaS services, and millions of websites. Netskope gives line of sight into both sanctioned apps (such as Office365) and unsanctioned apps. This ensures the security team can identify shadow projects that may have accidentally overlooked integration with the security team. Netskope decodes these activities to reveal rich details about users, groups, locations, devices, and data. This enables Sainsbury’s to go beyond seeing byte movement to gaining real insights and taking granular, policy-based action to mitigate cloud risks, protect sensitive data, and stop online threats. Netskope helps the security team answer questions and enforce policies such as: “Block users from Team-X from posting non-compliant messages on social media,” and “Alert if any user uploads personally identifiable information (PII) to any big data app.”

Improving Production Line Efficiency with Ethernet Micro RTU Controller
Moxa was asked to provide a connectivity solution for one of the world's leading cosmetics companies. This multinational corporation, with retail presence in 130 countries, 23 global braches, and over 66,000 employees, sought to improve the efficiency of their production process by migrating from manual monitoring to an automatic productivity monitoring system. The production line was being monitored by ABB Real-TPI, a factory information system that offers data collection and analysis to improve plant efficiency. Due to software limitations, the customer needed an OPC server and a corresponding I/O solution to collect data from additional sensor devices for the Real-TPI system. The goal is to enable the factory information system to more thoroughly collect data from every corner of the production line. This will improve its ability to measure Overall Equipment Effectiveness (OEE) and translate into increased production efficiencies. System Requirements • Instant status updates while still consuming minimal bandwidth to relieve strain on limited factory networks • Interoperable with ABB Real-TPI • Small form factor appropriate for deployment where space is scarce • Remote software management and configuration to simplify operations

How Sirqul’s IoT Platform is Crafting Carrefour’s New In-Store Experiences
Carrefour Taiwan’s goal is to be completely digital by end of 2018. Out-dated manual methods for analysis and assumptions limited Carrefour’s ability to change the customer experience and were void of real-time decision-making capabilities. Rather than relying solely on sales data, assumptions, and disparate systems, Carrefour Taiwan’s CEO led an initiative to find a connected IoT solution that could give the team the ability to make real-time changes and more informed decisions. Prior to implementing, Carrefour struggled to address their conversion rates and did not have the proper insights into the customer decision-making process nor how to make an immediate impact without losing customer confidence.

Digital Retail Security Solutions
Sennco wanted to help its retail customers increase sales and profits by developing an innovative alarm system as opposed to conventional connected alarms that are permanently tethered to display products. These traditional security systems were cumbersome and intrusive to the customer shopping experience. Additionally, they provided no useful data or analytics.

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.”

Ensures Cold Milk in Your Supermarket
As of 2014, AK-Centralen has over 1,500 Danish supermarkets equipped, and utilizes 16 operators, and is open 24 hours a day, 365 days a year. AK-Centralen needed the ability to monitor the cooling alarms from around the country, 24 hours a day, 365 days a year. Each and every time the door to a milk cooler or a freezer does not close properly, an alarm goes off on a computer screen in a control building in southwestern Odense. This type of alarm will go off approximately 140,000 times per year, equating to roughly 400 alarms in a 24-hour period. Should an alarm go off, then there is only a limited amount of time to act before dairy products or frozen pizza must be disposed of, and this type of waste can quickly start to cost a supermarket a great deal of money.
