Protect Your MS Exchange Server - How to Patch Your System

Microsoft has identified some serious vulnerabilities on Microsoft Exchange servers globally. Given the importance of this we have decided to notify all our customers of this issue. If you use Microsoft Exchange you will be pleased to know that Microsoft has released security updates to resolve this.

These are zero-day vulnerabilities, which are actively being exploited by a nation-state affiliated group and could result in a data breach or cyber-attack against your organisation. If you have an Exchange server on premise, or hosted in a datacentre, it's highly likely you need to take action immediately. 

Exchange Online services, part of Microsoft or Office 365, are not affected.

Please read the official publication from Microsoft Security Response Centre for further information and how to patch your systems accordingly.

Microsoft Exchange Server - How to Patch Your System  These updates will need to be applied by your IT department, or whoever it is that supports your Exchange servers. 

We are working with our managed support customers to ensure their systems are updated, however, if you need any assistance from Chess or have any security concerns, please speak to your account manager, or follow our links below. You can also get in touch by raising a ticket on our Customer Portal
