Security is the main concern of my companies before transitioning to the cloud. Whether they are choosing to use a virtual desktop service managed from a third party vendor (Desktop-as-a-Service, DaaS) or one hosted internally (VDI), the safe handling of data on the back-end has always been of primary importance.

Despite the popular notion that DaaS does not provide a good security, compared to VDI, Desktop-as-a-Service can easily be justified as the safer and better alternative overall, explained in the next few sections. We have also compiled a short list of tips and useful features which will guarantee you a better data security for your company.


DaaS is a cloud-based service which hosts desktops in a multi-tenant model. This means that it provides a comprehensive solution to many different companies around the globe simultaneously and they are hosted under the same environment in the cloud. VDI, on the other hand, uses a single-tenant model which deploys the environment to a single user, which could be a whole company. Multi-tenant model is erroneously considered to be more unsafe, but it is in fact the opposite. Cloud infrastructure has strong data security practices which were put in place FOR the cloud which is powered by the Internet. On-premises infrastructure is often outdated and not well enough protected from newly emerging cyberattacks, while multi-tenant solutions’ main consideration is safeguarding company data and monitoring closely your networks with the cloud.

Data isolation

We already explained that using a DaaS service means that you are being provided with a multi-tenant cloud solution. Cloud vendors host servers for many companies and isolation of the data of the individual entities are of primary importance, making them experts in the field. This happens through different directories which DaaS providers use to separate data. The great benefit of this is that it also ensures that data access in case of hacker breach is limited to individual small directories, rather than the whole system (commonplace incidence with single-tenancy).

Data Encryption

One of the most useful security features with DaaS is data encryption. It is also the most crucial one to implement as this gives companies far better confidence in the quality of their desktop service and the protection of their sensitive content. The important bit here is to make sure that your DaaS provider encrypts ALL of your company data and not only partially, taking into account all of the unlikely scenarios which may happen to endanger your data when the end-users are operating their devices. Encryption may affect the high performance of your desktop service, so checking these points with your provider in advance is crucial.

Multi-factor authentication

Another common security feature offered by cloud providers is multi-factor authentication. If you don’t know what this means, this is basically the two factors that the end-user has to provide to access their desktop environment. One of them is usually a password generated for the individual user, and the other factor is oftentimes a token which is in the possession of the user, allowing them to create a unique code at entry. This way, hackers don’t have easy access to your sensitive information and your data security is very much guaranteed at access level.

The Right Security

Endpoint security is the main point of our discussion here and DaaS has got it right. The reason why this is the case is that Desktop-as-a-Service provides a single uniform environment which is handled and monitored by dedicated IT staff, who are very much aware of what they should be watching out for. There are no hefty installations involved with each and every device, as all security updates, anti-virus and anti-malware are provided as a cloud service remotely. Dedicated IT staff can perform regular patching and deploying of extra security features to your desktop environment, which otherwise you can miss out on and compromise your data.

Communicate your requirement

As a final point, it is crucial when choosing a DaaS provider to communicate your security concerns carefully as well as your individual requirement for the service. Finding a cloud vendor that meets your needs and demands by providing you with all the necessary security features is of great importance to your data protection and how safely you will operate in the cloud environment!
