Tim Sadler, CEO and Co-founder at Tessian industry unlocked Real estate professionals and property developers are often dealing with sensitive data or confidential matters which need to be kept protected. We explore how UK property portal Rightmove implemented a Tessian email security solution to help do just this, while Ankit Satsangi, Head of Cybersecurity (CISO) at UAE-based Azizi Developments, discusses some of the unique cyberthreats to the industry. T 44 Tessian, a UK company transforming the way enterprises secure their email, has announced that UK property portal Rightmove has implemented its machine intelligent email security platform. As part of its wider cybersecurity strategy, Rightmove was looking for a robust solution that would prevent data loss caused by human error. The company turned to Tessian. Listed on the London Stock Exchange and a constituent of the FTSE 100 Index, Rightmove wanted to eliminate the threat of misaddressed emails. Additionally, it was keen to ensure that sensitive information was not being sent to unauthorised accounts. It needed a solution that would work across the various operating systems and devices that its employees use. After reviewing Tessian’s solution, Rightmove elected for two machine intelligent filters – Guardian and Enforcer – and promptly deployed the platform across its UK-based operations. By applying machine intelligence to historical email data, Tessian learns the relationships between employees and their email contacts, both internal and external. It understands normal email communication patterns and therefore can automatically detect anomalous activity. At the heart of Tessian’s technology is the Tessian Relationship Graph. Guardian’s machine intelligence prevents emails being sent to the wrong person through inadvertent human error, while Enforcer identifies and stops highly sensitive emails being deliberately sent to unauthorised personal email accounts. “We needed a solution that would thoroughly manage our outgoing emails without significant disruption to our employees and customers,” said David Cray, Head of Customer Experience and Product Development at Rightmove. “The Tessian platform seemed like a good solution for Rightmove as it causes minimum disruption to staff while reinforcing our internal data security policies and training. “This tool is an important part of our overall security strategy and one solution that Rightmove employees can easily engage with to help keep them and the business safe from human error.” Rightmove.co.uk is the UK’s largest property website, advertising around 90% of all homes for sale via estate agents across the UK. It enables people to search over one million properties for residential resale, new homes, rentals, commercial and overseas properties on Rightmove. Tools and information people can access on the site include sold prices, maps, nearby schools and ratings using a school checker tool, street view and floor plans while the service is directed at four key membership groups: estate agents, lettings agents, new homes developers and overseas home agents.
