IESnare – Are Bookmakers Spying On You Online?

What Is IESnare?

IESnare, also known as MPSnare, is a spyware that has played a pivotal role in preventing Internet fraud over recent years.  Developed by Iovation, IESnare is a popular spyware utilised by many online businesses, especially online bookmakers.

This is a highly controversial spyware, yet there is little awareness of its presence within the betting community.  IESnare is installed onto your computer/electronic device without permission and used to monitor online activities.

How Does IESnare Work?

Every single online activity requires a connection to a network.  The IESnare Spyware provides online businesses with an extra layer of control and intelligence.  Once installed onto an electronic device, IESnare monitors the online activity on that device.  The analysis is used to create a ‘digital fingerprint’ which can be interpreted by the business.

IESnare provides protection to networks in real-time by identifying the network devices that are being used for malicious, illegal, inappropriate or fraudulent activities.  IESnare then shares this information about the identified devices with all IESnare protected networks.

The information collected helps subscribed networks to make decisions about individual connections critical to business.  They can then know whether to allow, limit, or deny access based on the reputation of the connected devices.

Why Do Bookmakers Use IESnare?

Online betting sites use IESnare to monitor their customer’s online activities in order to detect fraudulent behaviour such as multi-accounting.  However, it has become apparent that IESnare is used to identify bettor who seek value from bookmakers.  Bookmakers can easily identify customers that use matched betting software.

Although matched betting is completely legal, bookmakers hate customers that seek value from their business model.  Due to this, bookmakers can easily restrict/ban betting accounts.
