decrypting myths Adopting a defence in depth approach for email security Email is the top communications tool used by modern organisations, with many now shifting from on-premise to cloud-based. And while this has numerous business benefits, it also means that security must be top of mind. Werno Gevers, Regional Manager – Mimecast Middle East, tells us why organisations should look to adopt a defence in depth strategy for long-term cyber resilience. hHow important is email as a tool for organisations and what kind of trends have you seen in terms of a shift from on-premise to cloud-based? We’ve seen a big shift. Email is the number one business communication tool used by most organisations. It’s usually one of the first platforms organisations move to the cloud. We’ve seen cloud email security services from Microsoft and Google dominate the global market and these are now accelerating in the GCC. According to Gartner, 84% of IT decision-makers indicated that they were currently using or planning to use Microsoft Office 365 in the next six months. We also see, according to some of Gartner’s other research, public cloud services revenue in the Middle East and North Africa is expected to total nearly US$3 billion by 2020 – an increase of 21% year over year. How would you say that the COVID-19 pandemic has accelerated this shift? It has been a remarkable catalyst for Microsoft adoption. Teams adoption increased by over 40% in a month and Office 365 is a collaboration platform, so businesses had to accelerate their cloud adoption strategy to cater for the remote workforce demand. Also, another Gartner forecast report highlighted that Software-as-a-Service accounts for 53% of the total public cloud service revenue for the Middle East and North Africa, and this is set to total 1.6 billion in 2020. Why is email such a target and how detrimental are attacks via this vector? Email was never designed to be mission critical and to house up to 80% of an organisation’s intellectual property. But, seeing that email is the primary form of communication, it offers an open channel for attackers into any organisation. It is much easier for hackers to exploit human vulnerabilities through social engineering, while a lot of business processes are dependent on email as well. But while most email system providers offer some level of security and resilience, they fall short of what many security and IT teams would consider www.intelligentciso.com | Issue 29 67
