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.
