What is our primary use case?
We are a Microsoft-oriented company. All our main infrastructure for user systems and productivity, like Microsoft Office and email, are from Microsoft. So we use Microsoft products and we use Active Directory on-premises. We have also built a cloud infrastructure and we now have a completely hybrid architecture. As a result, it was mandatory to configure Azure Active Directory to synchronize with the on-premises Active Directory.
We have finished that project and now we use Azure Active Directory for users who are on the cloud.
How has it helped my organization?
Entra is very good for the organization because we now have many users, due to COVID, who are working from a distance. With Microsoft, we can give them the opportunity to download all the applications on their personal PCs, like Teams, OneDrive, et cetera. They have a single sign-on and they can log on from everywhere.
The solution has improved things a lot for our organization because it has improved productivity. One specific effect is that we used to use a lot of VPN access, but we have decreased that access by 80 percent because they don't need the VPN anymore. And productivity has also improved very much, because users can do their jobs from everywhere, even on their mobile phones, because they have their files on OneDrive. With Azure Active Directory, we don't have security issues thanks to the added security on the cloud, such as MFA and also Defender for Endpoint.
But it's not only productivity tools that we have on Azure, we have other applications as well that we have set up for our users, like SAP. We have also diminished our telecom costs.
We have saved a lot of money, I'm very sure about that. We pay for the solution but because it is in the pricing agreement, we have more tools available and we don't have to buy more. I would estimate it has saved us more than 40 percent.
In addition, before, we had to work through all the horizontal firewalls and security sensors in the company. Now, we have separated the productivity tools like Word, Excel, OneDrive, and Teams. That means our users are very pleased with the user experience. They like using it. They can work from home or at the company and their files are synchronized.
Overall, we feel our security has improved and we are confident.
What is most valuable?
I like the fact that I can manage the users, but it's also a security resource. Let's say we decide that our users need to have MFA - multi-factor authentication. It is very easy to implement that with Azure Active Directory.
What needs improvement?
What could be improved is the environment. It still has administration centers in Office 365, and the same is true for Azure in general. You can manage the users from the Office 365 administration center, and you can manage them from Azure Active Directory. Those are two different environments, but they do the same things. They can gather the features in one place, and it might be better if that place were Azure.
For how long have I used the solution?
I have been using Azure Active Directory for five years.
What do I think about the stability of the solution?
The stability is very good. We don't have incidents. The only issues we had were to do with synchronization that took some time between Active Directory on-prem and Azure Active Directory. But that might have had something to do with other issues.
What do I think about the scalability of the solution?
It is a 100-percent scalable solution and that is one of the reasons we chose it.
We have installations on-premises, and people all over the country, including the islands, the north, and everywhere. Our users are in multiple locations. It's used across different departments with different applications and needs. At this moment, we have about 2,300 users.
How are customer service and support?
Microsoft's technical support needs to be improved. It's a bit bureaucratic, to put it in one word. The procedure for opening a case is that someone sends you an email to give them all they need. I would like the technical support proceedings to be faster. Sometimes, my company doesn't have this time. We need to find a solution very quickly.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
We used on-premises products like System Center Configuration Manager. We used Microsoft's products, but for on-prem administration, not on the cloud.
How was the initial setup?
Due to the fact that we have a hybrid architecture, not a clean cloud solution, it took us a lot of time. We had to consider how everything, all the applications, was going to work. Active Directory is also involved in emails and there were many procedures to consider and test. There were also many users who were staying on-prem. We also had to consider external cooperation with other European and domestic energy companies. So it took us about one year. Our company is not a simple company, like a sales company or a manufacturer. We deal with critical infrastructure and we have to control and operate the power for the whole country. We had to think about every step of the journey.
We had 10 to 12 people involved. I was the project manager and there were three groups of people, in addition. One was from telecom and security. There were a few people from infrastructure and technical support, and there were some people from the application side, to test that all our applications were active.
We also have teams for projects, like when we do a large construction for something like power lines. We form teams between departments and these special teams may work for a year on a specific project. We also needed to consider them because they have different needs and work from different places and are mobile.
Because we have on-premises firewalls in our company, we had to do some work before we implemented AAD to arrange access between the company's security system and the Microsoft cloud system so that they could cooperate and communicate. We had to open the protocols, et cetera. As a result, we don't have any problem with the consistency of our security policies.
In the beginning, it was a matter of getting used to the procedures. We needed to explain things to the users so we sent them a guide. We rolled it out to our 2,500 users in many batches over about four months.
There is periodical maintenance, such as upgrades, as well as ad hoc maintenance. For example, if we modify public folders, we need to do some work because, on one occasion, cloud users couldn't see a public folder that was on-premises.
What was our ROI?
We can see a return on the investment by comparing the prices we know from previous years. We don't use so many data centers now and we don't need as many installations and to pay as much rent.
Our return on investment is that the costs are very small, like one-tenth what they were, by going from owning on-premises data centers to what we have now. Over a period of five years, our return on investment is 100 percent. The money we pay for this contract is not much compared to the money you need for buildings, data centers, power, and technicians.
The price is also very good if you consider the money you save by not having to pay for many contracts with different companies to create a corporate solution. You pay one company, like Microsoft, and you have the whole solution. We have saved a lot of money by doing that.
Of course, you need to give it time and in-house resources. People have to be trained. Otherwise, if you have many environments and many products that you don't know very well...
Maybe using multiple companies is good. That's why we do use some other products, but not many.
What's my experience with pricing, setup cost, and licensing?
The price is fair. It's not very expensive given what they offer. Of course, we did some negotiating with Microsoft. We didn't pay the list price. We have been a Microsoft customer for many years, so when the contract comes due every three years, we discuss it. Afterward, there are some discounts.
Which other solutions did I evaluate?
We evaluated Amazon and Google. We chose Microsoft mainly because it has the whole package, meaning it has the security, the applications, and the infrastructure, so it's a more holistic approach compared to the others. It's not that Google and Amazon don't offer something like that, but they need more time to improve because they were not on-premises companies.
Microsoft gives you the space, the data centers on the cloud, and backups; it gives you everything. From the others, something was always missing. Microsoft may not be perfect, but it has everything you need.
What other advice do I have?
It's a very good solution, an excellent solution. It's very stable and robust. You don't need to do a proof of concept unless you have a special case, like, for example, fleet management, and have a very specialized application.
We use Entra’s Conditional Access feature but we also use other tools from other vendors. From our experience so far, we haven't had problems. Entra seems robust enough. We haven't even had one incident of malware. Of course, we have added some more tools to our cloud infrastructure for the mail applications in the network. So although it's robust enough, because we're handling critical infrastructure, as a company we decided to have more tools.
We use Intune and Endpoint Manager. Any device that is connected, even if it is a personal device, needs to be registered via Intune. We do not accept non-registered devices.
Azure Active Directory, and Azure in general, is a very big solution that we are developing further. It takes a lot of time, but by using it, we don't need so many other resources from outside companies. We can manage everything in-house. It takes a lot of time, but it's better than other options. It has more tools and better monitoring. Those extra tools mean more time spent on it by the administrators. But it has dashboards that they didn't have before. So the administration is easier and more centralized, but you need time with all these tools.
