Room For Improvement

CoreStack needs improvements in cost allocation, security, UI responsiveness, and AWS reporting, with better integration and governance.
Umbrella's base package may be complex and costly, exposing lower-budget enterprises to DNS risks and requiring specialized deployment.
The recommendations made in CoreStack to delete a machine have the potential to generate major cost savings.
Associate Vice President at Hitachi Systems India Private Limited
We need more security features, particularly since the market is increasingly demanding better security tools for cloud management platforms, including cloud security posture assessments.
Senior Vice President at a tech services company with 10,001+ employees
Adding features to automate tasks at the operations level could help provide better visibility across the cloud for our operational engineers.
Senior Solution Architect at Hitachi Systems India Private Ltd
There is no downtime or challenges.
Head Of Business Finance at Zensar Technologies
Umbrella can be improved with easier migration and easier deployment.
Managing Director
If they have a dedicated feature where, even after connecting to a VPN, the Umbrella roaming client should be online and it should be able to detect and follow whatever policy is applied, that would make for no confusion.
Senior Network & Security Engineer at a computer software company with 201-500 employees
 

Setup Cost

Umbrella offers transparent, straightforward procurement with clear setup, but remote reporting limitations and deployment challenges require consideration.
My experience with pricing, setup cost, and licensing is that it is straightforward and has flexible pricing based on workload consumption.
Associate Vice President at Hitachi Systems India Private Limited
I believe has been competitively priced across the market.
Senior Vice President at a tech services company with 10,001+ employees
The cost compared to other solutions is really cheap.
Head Of Business Finance at Zensar Technologies
Umbrella is a high-enterprise cost product, so one should look at their budget before implementing this solution.
Soc For Ddi at a tech consulting company with 1,001-5,000 employees
On a scale of one to ten, I would rate Umbrella an eight because the deployment and the ease of use can always be improved, but the actual product itself is pretty well done.
Managing Director
 

Valuable Features

CoreStack enhances multi-cloud cost efficiency, visibility, compliance, and governance, improving operations, customer satisfaction, and resource savings.
Umbrella uses Cisco Talos for threat intelligence, providing robust security with DNS filtering and SaaS features for safe browsing.
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.
Senior Vice President at a tech services company with 10,001+ employees
The best features CoreStack offers are primarily the recommendations for cost optimization for RDS and EC2 machines.
Associate Vice President at Hitachi Systems India Private Limited
For example, from AWS, it provides visibility on EBS volumes that are not being used, and it gives recommendations to delete them and save some cost.
Senior Solution Architect at Hitachi Systems India Private Ltd
Umbrella has positively impacted my organization by allowing our IT team to know that our users and our remote locations are having safe traffic.
Managing Director
The most important aspect for me is FinOps and cost allocation, which helps us track spends by business unit, customers, features, or Kubernetes namespace, which helps us save on costs and generate revenue metrics for accountability and transparency.
Head Of Business Finance at Zensar Technologies
The best features Umbrella offers are web DNS filtering, website filtering, and it has better insight and visibility of what applications users are working on.

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.
