The era of cloud migration

Considering the fast digitalization companies are currently facing, as well as the pandemic that hits our nations, going towards a cloudarized infrastructure is something organizations are now highly considering.

Indeed, today’s organizations rely on the use of technology to keep up with constant innovation as well as the important market demand. Furthermore, the COVID-19 sanitary crisis highly affected the organizations’ way of working. From the office to the living room, our working environment has considerably changed. Therefore, the need for collaboration, data access, communication, and proper business applications requires, in most of the cases, a journey to the cloud.

But what does cloud migration imply?

Cloud migration involves the transfer of all your digital assets (data/processes/applications/resources/etc.) from your on-premise to the cloud. It should be seen as an extension of your organization’s perimeter and responsibilities. In addition to the on-prem classical data center or physical equipment, several virtualized resources you are responsible for are added.

Cloud migration’s benefits

This is no secret, cloud migration implies many benefits:

  • Cost efficiency & financial flexibility due to the monthly fee,
  • Visibility,
  • Business agility,
  • Fast time to market.

However, with advantages come also challenges. For example:

  • An increased attack surface,
  • Staffing and skills shortage as we need to train or hire people with cloud expertise,
  • Compliance and regulations that have been achieved on-prem have to be as well maintained in the cloud environment.

The cloud is an environment that we cannot physically manage, but that is still under our responsibilities. We need visibility and the ability to track every move in order to avoid or respond as fast as possible to any potential attack scenario.

How can we help?

Surely, as mentioned above, cloud migration has lots of advantages. However, moving to the cloud also implies the expansion of your risk’s surface. This is where we intervene.

At Excellium Services, we developed two work packages around Microsoft Cloud technologies.

On one side, we are able to advise you regarding Office 365 and Azure products. The general idea behind our work packages is to assess the cloud security posture and to identify misconfiguration as well as potential security vulnerabilities putting your organization’s infrastructure at risk. Our approach is two-folded: we first shift the focus on your organization flows, requirements and need before deep-diving into the configuration review based on CIS industry best practices.

And on the other side, we are able to continuously monitor your cloud infrastructure using different SIEM technologies. How do we do that? Let us tell you more.

First, we’ll run an audit in order to make sure that cybersecurity best practices are in place.

Then, the Excellium SOC team monitors your activity 24/7 based on SIEM Sentinel in Azure from Microsoft. In case of an alert, our SOC Analysts will immediately detect it enabling real-time intervention from our CSIRT team. Indeed, they will respond to the incident and limit damages.

Let’s play

According to you, what is one of the main disadvantage of cloud migration?

A. Less visibility,

B. Higher maintenance cost,
