Remote monitoring has streamlined endpoint management and consistently reduced ticket resolution time
The best features Atera offers include the per-technician pricing, which is honestly one of the biggest things. Unlimited endpoints for a flat monthly fee per tech is a model that makes sense for us, since we are not paying more every time we add a new endpoint. The AI Copilot feature has been a nice addition that helps our techs summarize tickets and suggest fixes faster, which has cut our resolution times noticeably. The AI Copilot feature has specifically helped my team because the automation handles a lot of the routine work, such as patch deployments, maintenance tasks, and monitoring alerts. Atera has positively impacted my organization by transforming how our team operates day-to-day, and the pricing model is hard to beat. The outcomes or metrics showing how Atera has made a positive impact include the 30% reduction in ticket resolution time I mentioned earlier.

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

"One thing that I'm most impressed by with Atera is how much they listen to their community to focus on more integrations."
"Just because it is low cost doesn't mean it is low quality."
"There are a lot fewer hardware replacements. Once people migrated from old style hard disks over to SSDs, you have things like hard disks filling up faster. So, I run a script to clear out all the waste, e.g., all the temporary files and downloads. A lot of our business runs through a custom web application that we built. This involves people downloading a lot of PDFs and Excel files, and not just having them sitting in folders. With Atera, I can just go through and clean the temporary files out."
"I have better access when I go to look for something regarding either a specific user or software. It is easier to locate. When I am troubleshooting with my clients on the phone, I am not fiddling around looking through a bunch of ticket notes trying to locate something. It makes me a lot more efficient."
"It is reliable, and when it is working, it works without issues."
"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."
"Moreover, I find that if it wasn't for Atera, I wouldn't be gaining the number of clients I have and growing my business as I do."
"All of the features of Atera are valuable because they allow the customers to achieve their goals. It is easy to use, has good collaboration, and has zero maintenance."
"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
"It's very easy to manage and monitor it."
"Being open source lets us customize it for our monitoring needs, saving us money."
"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
 

Cons

"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."
"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."
"While scalability meets growing needs, there haven't been many additions in the last two years."
"Having more freedom to perform identity access management would be great — it's one of the things that are necessary for a lot of companies they secured."
"The mobility of Atera is also a feature which needs to be addressed so that it can be used on iPads, iPhones and things of this nature. I would also like to see an agent included on these devices so that I can monitor, maintain and manage them."
"I also use Apple Zoho, which does not require you to download anything. You can get help from Zoho. Atera, on the other hand, requires you to download an applet."
"The one thing that could do with improvement is the reporting."
"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."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"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."
 

Pricing and Cost Advice

"The price is reasonable for what we require."
"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 solution cost approximately $200 Canadian per month."
"Atera happened to have the best pricing model."
"Pricing is my favorite part of it. It was per user, not per client."
"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."
"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."
"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."
"The pricing is quite reasonable, especially when compared to the broader market."
