Review summaries and opinions

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

ROI

Sentiment score
7.2
CTERA Enterprise File Services reduced costs and time, minimized manual storage, and eliminated SSD and alternative storage needs.
Sentiment score
7.3
Organizations benefited from Office 365 with cost savings, productivity enhancements, flexibility, integration, improved security, and valuable Microsoft support.
Adding SSD storage to Windows file servers is expensive, and we no longer need to back up those devices.
I am positive that CTERA has helped reduce the total cost of ownership by eliminating the need for manual storage management and reducing storage service processes.
 

Customer Service

Sentiment score
8.3
CTERA's platform provides responsive support, rated highly for proactive assistance and efficient issue resolution by knowledgeable agents.
Sentiment score
4.2
Office 365 customer service is highly rated for responsiveness, but some users prefer internal IT or community resources.
They swiftly address concerns and take ownership of the call, providing a very satisfactory support experience.
High-priority issues are handled promptly.
I would rate their support a ten out of ten.
 

Scalability Issues

Sentiment score
8.3
CTERA's platform is scalable and easy to expand globally, though CPU and memory licensing constraints may pose challenges.
Sentiment score
7.8
Office 365 efficiently scales to accommodate organizational growth, handling thousands of users with high adaptability and licensing flexibility.
If we need to upgrade CPU and memory, we should be able to do that without a license upgrade.
CTERA is a very scalable product, allowing us to grow.
It offers good scalability options, including vertical and outward scalability.
 

Stability Issues

Sentiment score
7.5
CTERA's platform faced initial bugs but improved over time, earning high stability ratings with reliable data access.
Sentiment score
7.4
Users find Office 365 reliable, appreciating improvements and support, despite minor issues with Excel macros and Teams connectivity.
It has been pretty stable since then.
We had things deployed for years, and we were suddenly getting cloud sync issues that were crashing our sites.
It is very stable and reliable.
 

Room For Improvement

The CTERA platform needs improvements in monitoring, updates, UI, logging, and performance, while users value current features and support.
Office 365 faces challenges with platform compatibility, performance, costs, integration, and requires enhancements in user-friendliness and documentation.
AI and automation features could enhance the platform, such as AI-powered search, predictive storage analytics, and intelligent alerts for proactive monitoring.
It would help to have a global single-pane-of-glass view of all my CTERA devices.
One suggested improvement for the CTERA Enterprise File Services Platform is the ability to distribute data across multiple active backend storage nodes rather than the current limitation of a single active node.
 

Setup Cost

CTERA offers cost-effective enterprise file services with flexible licensing, providing significant savings over EMC and Nasuni, especially in Israel.
Office 365 provides scalable licensing plans offering good value and flexible pricing, although setup can be complex for larger enterprises.
Unlike other solutions that require hardware purchases, CTERA offers software licensing with flexibility across multiple infrastructure providers.
CTERA's pricing seems to be on par with some of the other players, such as Nasuni and Azure.
I find the pricing reasonable.
 

Valuable Features

CTERA excels in scalability, flexibility, data management, and protection, making it ideal for hybrid cloud and remote work environments.
Office 365 enhances productivity with strong integration, collaboration tools, AI features, scalability, cloud storage, and comprehensive app support.
As soon as something is written to the device, CTERA copies it to the cloud, where it's versioned with snapshots so we can recover it.
A vital advantage of this platform is its instantaneous recovery capability, allowing seamless access to a secondary gateway if the primary one fails.
It is a three-in-one solution for us. It is a file-sharing platform, an archiving solution, and also a backup solution.

Featured Reviews

Igal Muginstein - PeerSpot reviewer
Offers flexibility, fast performance, and ransomware protection
The platform is releasing new features at a fast pace, which sometimes leads to version updates every three to six months. Although updates are generally not complex, it is challenging to stop the production environment during these updates, even if the downtime is just a few minutes. This is a common challenge across all NAS providers. From my perspective, the most important area for improvement is developing a method to perform updates without affecting customer production environments. Additionally, there are some cache size limitations that might become problematic for future use cases, though they don’t impact current applications. Collaboration for NFS and SMB protocols could also be enhanced. Although this issue isn't specific to CTERA, it is something we are working on together to improve. The quality of the versions has improved, but occasional issues still arise. All solutions face this challenge, but we hope to see a continued reduction in the number of bugs. That said, we haven't had any major production problems in the last four years, and we appreciate how responsive CTERA is to our issues. We engage in brainstorming sessions together, and we value this relationship.
Gary Cook - PeerSpot reviewer
Access to advanced features boosts productivity despite pricing concerns in developing regions
I need to do maintenance for Office 365 very seldom, once a year. In the maintenance process for Office 365, we have about 12 people involved. For the maintenance side of Office 365, only one person is involved. Looking at Office 365's pricing, I would give it a 4 on a scale from 1 to 10. My overall rating for Office 365 is an 8 out of 10, but for the product itself, I would give it a 10. I would definitely recommend Office 365 to other businesses, probably a 9 out of 10 for recommendation. This is only because of its price and the fact that they do not take into account developing countries such as South Africa, where they should give us more favorable prices or local prices. We do not have a partnership with Microsoft, which is a sore point for us. We have reached out to Microsoft South Africa, and they are very hard to contact and largely uncooperative. We are a B-Level 2 and a B-Level 1, which are local affirmative action ratings that companies get. Level 1 is the highest, and Level 8 is the lowest. We hold amongst the highest BEE ratings, but we have not found Microsoft South Africa to be forthcoming or very open. We should have a partnership with them, and we run Power BI as we are a Power BI shop now. I strongly would want to see a box within Office 365 for our team to have ChatGPT through OpenAI as well. We use Excel as a data source for many tasks and find that it integrates really well with Python. We write a lot of Python code and use Excel as a data sheet many times, and we operate through SQL and other zero elements as well. From an Office 365 viewpoint, we find that with Copilot and Python and Excel's provision for Python, it is very useful.
