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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"The most valuable feature is that it is something small that can be more easily deployed than a full data center set of servers."
"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 implementation process is okay."
"The UCS, which is by far the best management tool there is on the market, regardless of vendor. It's the only tool I see that gives you the opportunity to size and scale all the assets and capacity you have in your data center, from a unified view."
"It allows us to authorize our residents to come in using their own personal devices to access any of our clinical applications and ensure that the PHI is secure and protected."
"The compute storage and virtualization come all in one box."
"Its most valuable feature is its flexibility."
"It is helpful as a backup solution."
"The ease of use is the primary valuable feature. This specific version is very straightforward. I like the ability to modify it and configure it based on the different policies."
"It's scalable."
"Tenable Nessus is one of the best vulnerability assessment tools, that I know."
"I have found the vulnerability assessment and the reports to be useful."
"Nessus' most valuable feature is vulnerability management because it helps to discover vulnerabilities proactively and integrates with patch management solutions so you can push patches."
"It is a mature tool."
"The automatic scanner and scheduler are pretty cool."
"Quick assessments, compliance scores, and results are provided without having to do agents."
 

Cons

"Lacks some integration and documentation could be improved."
"Its price could be better."
"The architecture separates data, computing, memory, and storage into different parts."
"I have been receiving a memory overflow message every day when I use the solution."
"I would rate the installation of Cisco HyperFlex HX-Series an eight out of ten. It can be complex."
"The documentation could be substantially better, but the product itself does everything it needs to do."
"We need to be able to scale out and not just up. When you want to scale up or scale out, you are quite limited."
"The solution's price could be affordable."
"They have added a new Tenable Nessus Expert. That is their new product, which caters to the cloud and everything else. I am assuming that the new features and product enhancements are based on that tool set, but we haven't reviewed it yet."
"I would like to see more on the automation side."
"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."
"They should try to create an all-in-one solution."
"The report for counters is too simple and would be improved by a dashboard."
"Tenable Nessus could include a broader range of IT assets."
"Pricing is one of the most important features, and it is something that they can improve on."
"The price could be reduced."
 

Pricing and Cost Advice

"Cisco is quite expensive, but not in the initial first buy."
"The product could be cheaper."
"They are not the cheapest on the market. But there's an old saying I like to quote: "If you know that you are getting what you pay for, it's fine if it's expensive.""
"I would like the pricing to be cheaper."
"The price is a bit high. It could be better, but the product is worth the cost."
"There is a recurring cost for the VMware license and the HyperFlex licenses."
"Our licensing costs are large, but it is combined between all of the Cisco products that we have."
"Here in Brazil... it is very expensive. It's very hard for almost all companies to buy even the small version of this solution."
"We paid about six thousand dollars per license."
"When comparing the price of Tenable Nessus to other similar solutions, such as Acunetix, Tenable Nessus is not as expensive. It is averagely priced in the market. We pay for the solution annually."
"The price of Tenable Nessus could improve, it is expensive."
"It has a fair cost and very good cost-benefit ratio."
"The solution is worth the cost. It's a good investment."
"Cost-wise, it's an affordable tool."
"We incurred a single cost for a perpetual license, although I cannot comment on the price as this is above my management level."
"The cost is around $4,300 per year. Use is unlimited. You don't pay more if you want to use it for another IP."
