Back in April we issued an update on more on-premises Microsoft Exchange vulnerabilities, following the widely-publicised vulnerabilities in March 2021.
Now our email security partner Hornetsecurity have released an infopaper setting out how moving business email to Microsoft 365, rather than on-premises Microsoft Exchange Server, is a good move from a security perspective.
So, is your business email in the cloud? If it isn’t, you might want to have a read of this.
As Hornetsecurity point out, there are some important differences between on-premises Microsoft Exchange Server and Microsoft 365 for business email:
|Microsoft Exchange Server||Microsoft 365|
|Security updates||Important updates need to be downloaded and installed to maintain security||Microsoft manages ‘patching’ centrally so the risk of delay or error is reduced|
|Preventing data loss||Regular backups are a must, and at least one needs to be off-line and off-site||Microsoft replicates data across multiple data centres, providing ‘data resilience’|
|Software lifecycle||The Exchange Server software has a lifespan (2013 goes end of life in November 2023)||Microsoft deals with all the software updates so it’s always the ‘latest version’|
|Resource management||Exchange Server needs a server platform to run on, and this needs to be maintained||Microsoft provisions and manages the servers in their cloud datacentres|
