Featured Reviews

Nuno Mendes - PeerSpot reviewer
High performance solution that makes it easy to efficiently manage VM resources
In our case as a credit recovery company working with the state, our infrastructure is fixed and stable as we don't have the same need for growth as other types of companies. That said, one of the biggest problems with HyperFlex HX is that if you want to adjust your solution in terms of processing power, memory, or disk capacity, you have to buy completely new hosts. From a financial perspective, it can be very expensive to do so, and from a legal perspective, there are all kinds of compliance issues we would have to sort out before buying any new solution or application. Since we as a company will only be operating for perhaps the next ten years, when our HyperFlex solution comes to its end-of-life in 2024 our next step will likely not be with HyperFlex or any other solution from Cisco. Instead, from a financial point of view, we will likely turn toward a cloud solution because, that way, we won't have to spend so much money on physical infrastructure. We are, after all, only a small company and HyperFlex can be very expensive for other companies of our size, whether in Portugal or elsewhere like the United States. One other area for improvement is in regard to HyperFlex's integration with VMware. HyperFlex integrates with a specific version of VMware in such a way that HyperFlex doesn't always resolve security issues with VMware at the same pace as what you see in native implementations of VMware. This has happened in one or two situations in the past. On the other hand, the integration is otherwise adequate, especially in terms of availability and virtualization features (such as being able to split up each of our four hosts within VMware).

Provided increased visibility across the organization's servers
The user interface of Tenable Nessus feels outdated and could be more user-friendly. Additionally, the documentation is not well-organized, which can be confusing when searching for solutions or specific information related to Tenable Nessus Professional. The reporting feature could be improved by allowing users to create their own templates instead of relying on predefined ones.

Quotes from Members

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

Pros

"It is helpful as a backup solution."
"By configuring networks, we are saving power."
"The ROI we have seen from the high performance that has saved us time and money."
"The speed, storage, and management are the most valuable features."
"You can administer things easily. E.g., if you need more power, you can add a system."
"The implementation process is okay."
"Cisco HyperFlex HX-Series is simple to use, user-friendly and has been best for our purposes."
"Cisco HyperFlex HX has improved the way our organization functions on the storage side by having one big storage space for hosting VMs. We do not have to provision other ones. That's a positive aspect of it."
"The most valuable features of Tenable Nessus include its ease of access and quick usability."
"The solution can scale well."
"The plug-in text information is quite useful."
"The most valuable feature is the installation of Tenable which is incredibly easy."
"The solution is great for scanning servers."
"The scanning and reporting features are the most valuable aspects of Tenable Nessus."
"I like its ease of use. It has the script that is pre-built in it, and you just got to know which ones you're looking for."
"The most valuable feature is how it scanned and detected through its database to let us know exactly what fixes we needed to put in place for the vulnerabilities. It detects and it also gives you the way to fix it."
 

Cons

"The initial setup is very complex because there were some issues. It is not clear to how set up this solution."
"We are working with a lot of different technologies and trying to manage them with one tool. The API could be improved for better integration with other systems."
"Deployment on-prem was quite difficult."
"The infrastructure team thinks that there are a lot of issues."
"We'd like the product to offer better integration with other products."
"With the cache disk fails in Cisco, the whole node fails, and the workload goes down."
"It would have been nice if the product provided some cloud integrations."
"Lacks easy integration with other vendors."
"Multiple steps to create an actionable plan will be a great addition to Nessus."
"Remediation needs improvement."
"To be honest, I haven't used it much to tell you that these are the things that should be improved. But I believe the UI should be enhanced somewhat. For example, there are two ways to find a report, and people are frequently confused as to which is the correct method for locating a full report. Sometimes they go in the opposite direction, so this is an area that may be improved."
"The reporting feature needs to be improved."
"Pricing is one of the most important features, and it is something that they can improve on."
"The reporting is a bit cumbersome."
"I have found it is sometimes difficult to control the Zoom meeting sessions. For example, it is difficult to know who is talking and when trying to mute everyone but the speaker you end up muting everyone. When using multiple screens it is laborious to find the control buttons, such as to start a session. Additionally, when a recording is done I have found it difficult to find them, there should be an easier way to retrieve them."
"I would like to have a management option after the network scanning."
 

Pricing and Cost Advice

"It is relatively expensive, but it can easily return value by freeing up other resources."
"It is highly priced compared to other vendors."
"The product is expensive. Other solutions are cheaper."
"We have a yearly license."
"Here in Brazil... it is very expensive. It's very hard for almost all companies to buy even the small version of this solution."
"The product could be cheaper."
"One of the challenges we have with HyperFlex is that they have a subscription fee for the operating system that runs on it, and if I remember correctly, it costs approximately $15,000 USD per month."
"Cisco HyperFlex HX-Series is a bit pricier compared to other brands in the market...There is a need to make additional payments towards the maintenance and support of the solution."
"Its pricing is great and can't be improved. It is very cheap. It is less than 2,000 pounds a license, and you can't really ask for more. It has unlimited IPs and unlimited scans. There are no particular pricing constraints. The only additional cost is the inherent cost of the people to actually review the actual scans."
"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"The solution is expensive."
"Cost-wise, it's an affordable tool."
"One problem with Tenable is its pricing policy. Optimal results can be achieved with Greenbone Solutions which has much more friendly pricing policies."
"The price is reasonable."
"The solution has a single price for unlimited assets."
"The pricing is much more manageable versus other products."
