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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"Most of our users are Cisco customers, so it fits in within the suites we use. Primarily for me, as a solution architect, it's the technology and architecture that is the most valuable. I know from my technical colleagues that it's easy to use and for the customer, the up-time is the most valuable asset. It's running, has low failure, and so on which is why we use it."
"It's very easy to use and quite a mature product."
"The solution is easy to use and to learn. It is well integrated with VMware."
"It has reduced the time it takes to put the servers in production by half the time."
"The speed, storage, and management are the most valuable features."
"Cisco HyperFlex is helping us to put everything in centrally so that we can manage in one place."
"It is a stable solution...It is a scalable solution."
"It is very scalable. It is also easy to scan."
"We have around 500 virtual machines. Therefore, we conduct monthly scans and open tickets for our developers to address identified vulnerabilities. These scans cover the servers, other network equipment, and appliances in our infrastructure."
"The solution is very stable."
"It also has an executive report where you don't have to provide the client all the detail for them to sift though. But if they wish to dig through the detail they can."
"The solution is great for scanning servers."
"The initial setup of Tenable Nessus is very easy."
"Security is the key number because it can start to scan with a few clicks instead of credits, which is a bit complicated. So simplicity is the first advantage. Then the generated reports are well done and easy to present to management. The quality of the scan is quite good in detecting the severity. The solution has simplicity. Also, it has frequent updates so that is also a valuable feature."
"The most valuable feature of Tenable Nessus is vulnerability detection."
"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."
 

Cons

"The product needs work in the area of deduplication which currently is inefficient."
"The solution could improve by having more customization."
"The deployment could be made a little bit easier, as we still seem to struggle with it a little bit for a day or so to get it running."
"Sometimes when there are multiple technologies involved in a support case, this is when there is a bit of a lag."
"I would like a lighter product; something which can be carried by a mere human. The typical size still looks like a stack of data center-sized servers, which is typically fine, but not so good if you want to carry it around."
"Does not support the stretch cluster, and the interface is not good."
"It needs improvements in terms of I/O. Sometimes I have felt it is slightly slow while we are trying to provision VMs or access VMs."
"I would have liked it to be able to back up the system to a cloud, to be able to work from any other place"
"Model OS costs (and its segregation schema for individual modules)."
"The reports should be improved in Tenable Nessus. For example, when you are auditing compliance with CIS standards. It provides very poor reports."
"Tenable Nessus could include a broader range of IT assets."
"Tenable Nessus could improve by having more steady updates which will reduce the vulnerabilities."
"There could be an integration between Tenable Nessus and other Tenable products. It will help us manage all the solutions using one dashboard."
"The tool needs to upgrade asset tracking."
"Online learning could be a bit better."
"The user interface of Tenable Nessus feels outdated and could be more user-friendly."
 

Pricing and Cost Advice

"There is a 30 percent additional premium that all the companies are charging for Cisco HyperFlex HX-Series because of the lack of chips and bottlenecks in the market. The cost of the solution is high right now."
"Comparable solutions with switches, storage, and services are cheaper than HyperFlex. It should be cheaper."
"HyperFlex is relatively expensive, but you get good value for money."
"We currently have a perpetual license, which is kind of unlimited, so we don't have the normal licensing cost, yet."
"We are on an annual subscription and the price is fair."
"It is highly priced compared to other vendors."
"We would not have invested if we didn't feel the return was there for our customers."
"There is a recurring cost for the VMware license and the HyperFlex licenses."
"I think the price is fairly affordable. It provides a license that is fair."
"Tenable Nessus needs to be licensed. We own a license for the security center and that license is charged by the number of IP addresses that you can scan. You're allowed to have as many scanners as you want and there's no license for the number of scanners. We have a bunch of Nessus scanners out there, and as long as we're comfortable with staying under that IP address limit, that's really all we have to be concerned about."
"We have a subscription, the licensing fees are paid yearly, and I am using the latest version."
"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."
"We incurred a single cost for a perpetual license, although I cannot comment on the price as this is above my management level."
"The product is free."
"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."
"The solution is worth the cost. It's a good investment."
