Cyber Security & Data Breach Communications

“In a crisis you will want MCM in your corner.”

Michael O’Connell Partner, Advocate, Appleby (Jersey) LLP

We help businesses and organisations shape their messages and communications strategy following a serious data breach or cyber attack.


There are complex communications challenges that result from the General Data Protection Regulations. Companies who find that data has been seriously compromised have to communicate with the authorities and with customers, stakeholders and the media. The speed of that response is also important as is the need for clarity and reassurance for customers at what can be a troubling time. Getting this right is essential in order to protect the businesses reputation and brand.


We were at the heart of the communications response for a global law firm at the centre of one of the world's largest ever data thefts. We have also handled communications for a range of other sectors including leisure and hospitality, retail and fintech, where customers have needed to know their data has been compromised.


We also partner with a UK based contact centre so that we have the capacity to scale up our communications response and reach many thousands of customers at the same time.
