Owner at Sytex Ltd.
Quick setup and efficient automation boost IT consulting services
It would be beneficial if Atera implemented telephone support for general questions. When onboarding new clients and creating their portal, it would be helpful if presidents or company owners could see the current configuration progress step-by-step, rather than relying solely on email and ticket systems. The task system for technicians could be improved by adding recurring task capabilities. This would allow technicians to have checkmarks and task lists they can mark off as completed. While scalability meets growing needs, there haven't been many additions in the last two years. They are adding new features gradually, but there is always room for improvement.

Operation Director at Digital Pulse Sdn Bhd
A suitable choice for unified and efficient infrastructure monitoring across diverse environments providing user-friendly GUI, cost-effectiveness, and versatility
We use it for this specific client, they've deployed multiple instances of it across various locations to facilitate monitoring. To effectively monitor their infrastructure, it seems necessary to implement additional monitoring solutions for all three types of devices they have Nagios Fusion…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Atera has saved our organization money. We look at Atera as an extra employee that we only pay about $300 a month. This is incredible savings over having to hire somebody to do all the tasks that Atera performs for us."
"Atera has helped me to provide more accurate solutions based on a given problem. For example, we base our solutions on event scenarios, like the alerts. We identify that there's a series of problems occurring in a particular area from the information provided by the alerts."
"Atera saves money. A trip to the customer costs between $20 to $30. Then, you need to charge the customer $20 to $30 for the travel. However, if you are doing this work remotely, then you are not driving. This makes the process easier and saves money for you and the customer. For example, if it is just one machine, then the savings comes out to $50 to $60. If we are talking about a huge client, who has hundreds of machines and is changing their infrastructure, that is a lot of money."
"It is reliable, and when it is working, it works without issues."
"The most valuable features of this solution are automatic batch matching and unattended support access."
"We value the alerts that come with the product which allow me to reach out to my clients. Overall, Atera generates additional revenue streams for work done on their machines."
"It's very easy to use, not just for me, but even for people who have claimed, "I'm not very good at IT." Once you have it installed and you have it set up, it pretty much works by itself. It really helps you do what you need to do. It's easy to use for a beginner, compared to some of the other larger RMMs that are a little bit more complicated."
"Measuring the integration is very helpful when using Atera Assist Test. It takes the solution to the next level by automating activities. It doesn't just provide the solution but also allows running scripts to fix issues before a technician has to work on them."
"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
"It's very easy to manage and monitor it."
"Being open source lets us customize it for our monitoring needs, saving us money."
 

Cons

"They are working on an update, and I would like to see more stuff outside of just computers and servers. Increasingly, we need to be able to monitor and manage network devices. Atera is improving on that already, which is one place that it is currently lacking."
"It will be interesting if Atera can integrate all kinds of products. In North America, there are a lot of resellers, like Ingram Micro, Tech Data, Arrow Electronics, etc. It would be amazing if Atera could integrate with these products. If they could integrate with these products for MSPs, it would be much easier. Then, if you are buying something, and need to add something, you don't need to jump from place to place because this is a very quick sales instrument for use on a daily basis."
"The one thing that could do with improvement is the reporting. This is from someone who worked in an MSP, where I would want to run a report and be able to just present that to a client."
"There is definitely room for improvement with its automation capabilities."
"It should improve its processes."
"I would like to see more mobile device management. iPad is a big one. I know they've been working on some of that. For me, it would be amazing if I could do tablet devices and even expand it to POS systems or the like. I know that a lot goes into that but I've seen it is an area they're looking at."
"The billing module has a standard layout which is too limited for my needs."
"Having more freedom to perform identity access management would be great."
"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
 

Pricing and Cost Advice

"With Atera, the more you add, the cheaper the cost of the additional endpoints will be."
"Atera happened to have the best pricing model."
"One of the biggest issues I face is the need to pay per technician. I've dealt with other platforms that you need to have 250-500 devices. Even though the cost declines as the number of devices a person has increases, they still require you to pay for 250 or 500, respectively. With Atera, the number doesn't matter as you always pay the same amount. I approximate that Atera saves me $100 per week."
"The price is reasonable for what we require."
"The value of the product is perfect, neither cheap nor expensive. I think it is the right rate. It would be awesome if it continued to be the same price because it is a great solution that I like. I like it because I'm not paying per device. I have some customers on monthly contracts and some of them are on break'n fix. If I have a client who is on break'n fix, and they need to pay per agent, then I am losing money. If they were ever to change structures, going to pay-per-device model, then I would need to think about changing to something else."
"Our company is a startup. The initial reason I looked into Atera was the fact that you pay by the technician, not per-device. That means you are able to jump right in with a service without having a large overhead."
"It comes with unlimited devices, so the fixed price cost is taken out of my budget. So, I'm all good."
"Atera's pricing stays fixed and predictable, enabling us to add more customers and unlimited monitored devices. We still have a number of clients who fit a break/fix IT model. This is something where clients are complaining more about having to pay extra month-by-month for technology services. With Atera's model, we don't have to be going out and asking for more from clients each month. Right now, with where we are at in terms of scale, this is very important to us."
"The pricing is quite reasonable, especially when compared to the broader market."
