New Call-to-action

Advanced Technology Required To Prevent Advanced Threats

Given the major clients RDJ work with on a daily basis and their dependence on email for internal and customer communications, security is a top concern for them. RDJ wanted a SaaS solution that would match their Office 365 cloud-based email deployment. Knowing the long history and success, they decided to trial Barracuda, specifically the Barracuda Office 365 Essentials solution due to Barracuda’s relationship with Microsoft.

Essentials for Office 365 offers multi-layer email security to prevent spear phishing and zero day attacks, defensible compliance archiving and discovery, and backup and restore capabilities for Office 365, including OneDrive for Business. As RDJ saw a lot of advanced phishing emails and targeted attacks, they knew a solution that had the capabilities to block these advanced, malicious attacks was crucial.

Cloud Based Archiving

Ronan Daly Jermyn LLP was resigned to journal capture to an external device, but this was not optimal as they wanted a cloud-based solution that would support their migration over to Office 365 in real-time. When they learned of Barracuda Essentials’ archiving solution, the product sounded like a perfect fit. By configuring journal archiving, they could guarantee email was preserved ‘in motion’ and could easily provide logs whenever they were required, demonstrating that email had indeed been sent or received.

“Initially we did a lot of research as to how to best set up the Cloud Archiving Service – there were a lot of options, all we really wanted to do was capture everything to a secure repository. In discussions with Altinet’s engineers, it turned out we didn’t need to do anything except point our instances of Office 365 to the Cloud Archiving Service and the capture would occur automatically.”

OneDrive & Sharepoint Data Protection & Compliance

Due to RDJ’s scattered offices across the UK and Ireland, having a cloud based, centrally managed backup solution was key. Another key requirement for the team was the ability to backup OneDrive and SharePoint to protect against accidental data deletion that is a big risk when dealing with important shared documents. When backing up OneDrive for Business, all files under the Documents Library, including the entire folder structure, are protected, giving RDJ’s team peace of mind.


New Call-to-action


When implementing SharePoint Online and OneDrive protection for RDJ, Altinet could eliminate the risk of lost content due to accidental or malicious deletion. One key requirement was the ability to also retain email messages and files indefinitely if users were to leave the organisation – all without having to purchase additional licenses.
