Featured Reviews

Israel Cavazos Landini - PeerSpot reviewer
Weekly insights and risk analysis facilitate informed security decisions
I appreciate the weekly insights Zafran provides, which include critical topics for networks and IT security, allowing us to evaluate which insights apply to our environment. The organization score feature is valuable to keep the leadership team updated on how our infrastructure fares security-wise. The applicable risk level versus base risk level feature is beneficial because prior to Zafran, we only used the base risk level, but now understand that risk depends on the asset itself. Zafran is an excellent tool.
AnubhavGoswami - PeerSpot reviewer
Attractive automated reports with boost user productivity and an easy setup
The primary use is mainly related to vulnerability assessment, including both public and internal IP addresses By using this tool, we have reduced the workload and increased the productivity of users. It generates automated reports. This feature is beneficial when sharing reports with clients as…
HarshBhardiya - PeerSpot reviewer
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"Zafran is an excellent tool."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"For us, the most valuable aspect of the solution is the log-sequence feature."
"We are able to create a report which shows the PCI DSS scoring and share it with the application teams. Then, they can correlate and see exactly what they need to fix, and why."
"The most valuable feature of Acunetix is the UI and the scan results are simple."
"The solution is highly stable."
"The scalability is good. The scalability is more than good because it can operate both as a standalone and it can be integrated as part of applications. So that really makes it a very, very versatile solution to have."
"The vulnerability scanning option for analyzing the security loopholes on the websites is the most valuable feature of this solution."
"I haven't seen reporting of that level in any other tool."
"The most valuable feature of the solution is the speed at which it can scan multiple domains in just a few hours."
"Tenable integrates well with other solutions such as SIEM and batch management."
"It is easy to deploy and easy to use. Its reporting is good. From this reporting, you can see the pain point in your network, which makes it easy to fix them. It is easy to understand the reports and export them."
"It allows me to prioritize efforts and utilize effective technical resources."
"Once you get past the initial implementation, the solution is very stable."
"Tenable Nessus has a good performance, is very user-friendly, and is easy to use."
"The reports are pretty nice and easy to understand."
"The most valuable feature is the installation of Tenable which is incredibly easy."
"With the Tenable Nessus enterprise edition, you have unlimited licenses to scan the device."
 

Cons

"Initially, we were somewhat concerned about the scalability of Zafran due to our large asset count and the substantial amount of information we needed to process."
"The solution's pricing could be better."
"The only problem that they have is the price. It is a bit expensive, and you cannot change the number of applications for the whole year."
"We want to see how much bandwidth usage it consumes. When we monitor traffic we have issues with the consumption and throttling of the traffic."
"Acunetix needs to improve its cost."
"Currently only supports web scanning."
"Tools that would allow us to work more efficiently with the mobile environment, with Android and iOS."
"Integration into other tools is very limited for Acunetix. While we're trying to incorporate a CI/CD process where we're integrating with JIRA and we're integrating with Jenkins and Chef, it becomes problematic. Other tools give you a high integration capability to connect into different solutions that you may already have, like JIRA."
"Acunetix needs to include agent analysis."
"Tenable Nessus could improve the price."
"Vulnerability recommendations are outdated and not in line with industry standards."
"Technically, it is an excellent and the best solution available in Libya. My only concern is related to its pricing. They are an emerging company in Libya, and they need to put in some effort to provide us with very good prices so that customers can go with the best solution. Chinese companies are getting into the market here, and they're providing very cheap solutions."
"The reports are okay, but the interface is a bit difficult to navigate in some cases."
"The reporting is a bit cumbersome."
"The scalability of Tenable Nessus is good. However, it could be more flexible."
"We have had some false positives in the past, which we hope can improve in the future."
"The professional version is not very scalable."
 

Pricing and Cost Advice

Information not available
"When we looked at all other vendors and what they were asking for, to provide a third of what Acunetix was capable of doing, it was an easy decision... But now that it's coming to a cost where it's line with market value, it becomes more of a competition... Acunetix is raising the cost of licensing. It's 3.5 times what we were initially quoted."
"All things considered, I think it has a good price/value ratio."
"The solution is expensive."
"The price is exceptionally high."
"Implementing Acunetix needs a medium or larger business agency, because you need some money to get Acunetix. It is costly, but if you care about your agency's security, then maybe it's a cost that might help you in the future."
"I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."
"The pricing is a little high, and moreover, it's kind of domain-based."
"Acunetix was around the same price as all the other vendors we looked at, nothing special."
"The price of the solution is reasonable."
"Nowadays, your vulnerability applications are going to be kind of pricey because lots of them, including Rapid7, are based upon a base price, but then they add in the nodes. That's where they get you. If you're a big network, obviously, you need to scan everything. Therefore, it's going to be costly. The risk and insurance money associated with having ransomware on my networks is going to cost me more money, time, and marketing than the price of the tool. That's why I'm speaking only as an information security officer to security operations. This is the tool that is there in my toolbox to say whether we vulnerable or not. At this point, I don't care about how much it costs my company to have it because if I wasn't able to report it and we got ransomware, then who cares? I'm probably going to be out of business because it happened. That's why I don't care about the price. I have it, and I could use it effectively and do my report. At the end of the day, even if we get ransomware, as long as I reported it, followed my protocol, and put in the change, irrespective of whether it was ignored or denied, I did my job."
"The newer tools are quite pricey. There is a case of some fine tuning that can be done in terms of licensing. The IP based licensing that is offered makes the tool very expensive. If they want the IT industry to adopt it, the price should be looked at."
"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."
"Nessus Manager is not an expensive product. It has its limitations, but the pricing reflects that. We have a yearly subscription."
"The price of Tenable Nessus could improve, it is expensive."
"The product is free."
"The price of the solution is reasonable."
