Valuable Features

CoreStack enhances compliance, efficiency, and cost-effectiveness through FinOps, governance, and centralized reporting, reducing misconfiguration by 25%.
Umbrella enhances security with AI-driven intelligence, reducing incidents and supporting hybrid workforces without VPNs through robust features.
The single pane of glass for multi-cloud cost optimization helps me day-to-day by bringing a lot of operational excellence; it saves a lot of time because rather than going to each and every account or multi-cloud portal, which takes a lot of time, having everything on a single pane of glass increases efficiency, delivers results in less time, and provides clear reporting that can be shared with the customer in PDF or CSV formats.

Featured Reviews

Manmohan Rao - PeerSpot reviewer
Associate Vice President at Hitachi Systems India Private Limited
Cost reports have driven accurate AWS workload optimization and continue to guide savings
I can suggest improvements for CoreStack, especially regarding reporting periods. I noticed that some of the cost optimization reports generated potential savings while considering systems that have only maximum utilization of 1% or 2%. The recommendations made in CoreStack to delete a machine have the potential to generate major cost savings, but such machines should not be listed for deletion if they have maximum CPU utilization of 1%. I have concerns about needed improvements primarily regarding AWS. If a customer is running ten virtual machines and one machine has a maximum of 1% utilization, it is considered as an idle instance in the report, which completely ignores that particular machine. This should not be the approach.
Srivathsanr R. - PeerSpot reviewer
Head Of Business Finance at Zensar Technologies
Gained clearer financial governance and have improved cloud cost visibility and forecasting
I do not feel that anything needs to be changed. Umbrella is solving the purpose and is on point. The UI is intuitive and user-friendly. The learning curve is very easy. The features provided are on point. There is no downtime or challenges, and it is easy to learn and easy to use. In total, I do not feel that improvement is needed as per our organizational use case. Maybe for other organizations, they might have some suggestions, but for our organization specifically, I do not feel that they are lacking somewhere. It is already providing us the best thing. Almost everything is working as we expect. Small things we do not always point out. I feel that it works well and we do not have such problems with them specifically.
