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.

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.

Quotes from Members

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

Pros

"I like that the glass is always half full with CTERA file services. It keeps the data hot for users on location and then tiers off older data. If you need it, the stub is still there. You can click on it, and it's back on the device."
"The solution provides substantial flexibility, allowing the separation of workloads across various hardware platforms without vendor lock-in. This flexibility makes it adaptable to future infrastructure changes."
"CTERA has out-of-the-box data protection capabilities."
"The solution provides data eviction, where unused data is evicted from the local file, freeing up space. It also allows data to be rehydrated from the cloud when needed."
"CTERA is a very scalable product, allowing us to grow."
"The CTERA Enterprise File Services Platform is a hybrid solution that supports both on-premises and cloud environments."
"The support is awesome. It is top-notch. I would rate their support a ten out of ten."
"CTERA's instantaneous and redundant file replication, available across multiple geographical locations, ensures easy and user-friendly recovery."
"The functionality that is most valuable is the solution's ability to detect patient data in email attachments. Whenever a user sends out an email with patient data embedded in an attachment, it triggers an alert. The tool can detect a social security number and various other forms of patient identity. Emails are then automatically generated and sent."
"It is very easy to deploy."
"Quarantine email alerts to users to allow the email to their inbox (tricky but handy) - tricky if one doesn't have third-party email security, handy if one has got good third party email security)."
"If you have a global solution, you can go from one product to the other very easily. And then you can share data between all the different tools of Office which is good because participation and sharing is very good. That's the most important aspect of Office 365."
"The phone VoIP product provides genuine a unified communication solution."
"The most innovative feature of Office 365 is the Power Apps, which allows us to automate literally everything that we want automated. For example, sending attachments to specific folders on SharePoint, adding people's SharePoint when certain apps are performed, or emailing certain people at certain instances, such as when you've done a follow-up with the CRM and you need a marketing email to be sent out at a particular point."
"The most valuable features of Office 365 are Word, PowerPoint, Excel, and Teams. Teams helped us to collaborate more through its call and document sharing features."
"I love all of the applications being interlinked. I do not have to separately work on an independent system when it comes to file storage, email, and other tools."
 

Cons

"They fixed all the requirements that we had in the beginning. The beginning was a little bit rough, but we tuned it nicely. However, in some cases, they could improve performance."
"One area for improvement is the migration tool, which at times does not work as designed, necessitating the use of alternative solutions like Robocopy."
"It has a learning curve."
"More monitoring from the platform would be good. There is some monitoring, but it is paid. It is a chargeable service. It would be good for that to be included in the base."
"AI and automation features could enhance the platform, such as AI-powered search, predictive storage analytics, and intelligent alerts for proactive monitoring. Predictive storage analytics will help with better capacity planning. There can be some sort of intelligent alerts for proactive monitoring."
"One of the bigger things that I would like to see is additional logging. There are logs in there. They provide us with the initial logs on what is happening on our CTERA device. I appreciate that, but they do not give us any further information. I would like to have more information on the logs themselves."
"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."
"I am looking for a process where version upgrades do not impact the customers. There is no downtime."
"In the next release, I would like to have a more intuitive tutorial."
"Normally, they have a way to work with specific developments, and I think they shouldn't allow the partners to make some changes they have made. When I have a client with a lot of changes, we have a problem with that because there aren't rules to develop inside the ERP, so you can do anything."
"I started working a lot on Microsoft Teams and I find it a bit vast. It should be divided out a bit so that someone can use it for basic functionality, like audio, video, and calls. Then, if someone wants more advanced functionality for file sharing and team creation, and so on, they could use a separate app."
"The security should be improved."
"The online applications have limited functionality compared to the local applications."
"Data protection and email security are almost the same for all the organizations, irrespective of their segment (SMB or enterprises), with standard subscription at least basic Data loss prevention and Advance threat protection can be enabled for SMB segments, it is available in enterprise version / Premium versions."
"The integration with mobile services is not so good. It's coming, but they could improve a lot."
"The feature to convert PDF file to a Word document needs improvement as well as the feature to save the file automatically when typing, without using the save command."
 

Pricing and Cost Advice

"It is hard to compare the costs if we want to retain the same model of a separate high-performance storage or certain things, but it is one of the cheapest solutions available in Israel."
"So far, pricing seems to be fine."
"It is fairly priced. I am not too involved in the pricing of what we used to pay, but it would have reduced the cost of ownership. I cannot give a figure, but the EMC solution was very expensive compared to CTERA."
"CTERA's pricing seems to be on par with some of the other players, such as Nasuni and Azure. They all have benefits, but CTERA is competitive for its features."
"CTERA's pricing model is competitive compared to other companies that achieve the same thing. Their closest rival is Nasuni, and CTERA is significantly more affordable than Nasuni."
"I find the pricing reasonable. They offered us deals that helped us. Especially with the upgrade to a bigger unit last year, they were helpful with the deal."
"I am not directly involved in the pricing aspects, but I understand that CTERA's pricing is competitive and within industry standards."
"​The pricing/licensing is easy to manage."
"The pricing is high and has actually caused us to limit the number of licenses we purchase due to budgeting."
"The pricing is not really high, but one can get the software with the license key for free."
"For the moment, we are paying on a monthly basis because we are still adapting the support and how we want to proceed. I think we will move to paying for the annual license."
"Most of the time, we purchase Microsoft Exchange licenses, which are less expensive and provide only an email platform and 50 gigabytes of email storage for free."
"We have a license to use this solution. We have an E3 license which covers many different solutions."
"Licensing fees are paid on a monthly basis, or we prepay them."
"The pricing is good for all the features that we receive, e.g., Skype for Business."
