The State of Email Security 2018 Report
The latest threats, confidence killers and bad behaviors—and a cyber resilience strategy to fix them
Crowe Clark Whitehill is one of the UK’s leading accountancy firms, acting as a long-term, trusted provider of audit, tax and advisory services. It employs 650 people at seven offices across the UK, and is a leading member of Crowe Horwath International, a network of 167 independent accountancy and advisory service firms in more than 109 countries.
Technology plays an important role in maintaining Crowe Clark Whitehill's leading position in its industry, so when Crowe Clark Whitehill decided to migrate its email platform from IBM Lotus Domino to Microsoft Exchange,the IT team had to decide how best to deploy the new solution.
On the one hand, an on-premise solution would require additional IT headcount, making it an expensive option. On the other, Microsoft’s cloud service could not guarantee that all data would be hosted on servers located within the European Union, a key requirement of UK Data Protection legislation.
"We quickly realised that the way forward was to work with a Microsoft partner in the UK that could offer us a full managed service – hosting all the data at a UK data centre and providing 24/7 support to avoid extra workload for our in-house team," says Ian Norman, IT Director, Crowe Clark Whitehill. After creating a shortlist of potential partners, Mimecast partner, Applicable, was chosen to manage the project.
Applicable helped Crowe Clark Whitehill deploy Mimecast UEM Enterprise as an email security, continuity and archiving solution. This solution was used to archive all email and attachments that were more than one year old, to ensure data security and reduce the time required to migrate.
"One of the problems with Lotus Notes was that we didn’t have a workable archiving solution and we had mailboxes up to 20GB," explained Norman.
Having a single, unified hosted service meant that Crowe Clark Whitehill no longer needed to deploy and manage multiple third-party systems on its networks, and so email management system complexity was virtually eliminated during the migration and beyond. Mimecast’s integrated email continuity solution meant that user downtime was avoided and that email security policies were consistently enforced throughout the move. In addition, the Mimecast UEM solution has enabled end-users to search their own archives using eDiscovery, a tool which can efficiently search through the whole of their available 10 year archive.
Norman continued: "Keeping and retaining our data for 10 years is something that Mimecast is easily able to accommodate – I have no regrets about moving the firm to a cloud-based solution. One of the best things is that we haven't had to go out there and buy loads and loads of tin, and that's saved us hundreds of thousands over the last few years!"
"Firms of our size - if they’re not already - should be looking at this as a viable solution."
