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.
Revathi VeeraRaghavan - PeerSpot reviewer
Provides comprehensive visibility and covers the complete attack surface
For some of the software, there was no life cycle or general information. We wanted them to give details in the database as and when the software comes. I raised a ticket for that, and after that, they updated the details for more than one million software. They should address the false positives generated in EASM. It is fetching assets that have Infosys as the keyword. They should fix that. When we click on the web application, it only shows potential web assets. The application details are not there. Overall, CSAM has matured a lot. These are the few enhancements that need to be done.
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"With Qualys CSAM, we can see which assets have critical application vulnerabilities. This feature helps us prioritize and address these vulnerabilities more efficiently."
"The most valuable aspect we receive from Qualys is the remediation."
"The most valuable feature is the real-time visibility Qualys CyberSecurity Asset Management provides into all assets across our development and operational environments."
"The end-of-life and end-of-service software and hardware are some of my favorite features."
"Authorized and unauthorized software visibility is the best feature for me. It helps me understand security controls on our network and where we lack visibility. With a single security tool, we are able to get an extensive list."
"Qualys CyberSecurity Asset Management has helped to improve the organization's security posture significantly."
"Authorized and unauthorized software visibility is the best feature for me."
"Qualys CSAM helps find all the assets. It categorizes information based on various criteria such as host and tenant version. It provides in-depth visibility into both hardware and software."
"The most valuable feature of Tenable Nessus is the dashboard. They are convenient to use."
"Tenable Nessus has a good performance, is very user-friendly, and is easy to use."
"The most valuable feature of Tenable Nessus is vulnerability assessments. There are a lot of threats around the world and this solution is the first to come out with detection rules."
"We have done code scanning for a long period because as a company, we do DevOps as part of our development life cycle."
"It allows me to prioritize efforts and utilize effective technical resources."
"I have experience with it on my attack stations, and it's pretty good to optimize. Personally, I think Nessus is quite a good product."
"The support has been really cooperative."
"I have found the vulnerability assessment and the reports to be useful."
 

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 deployment is somewhat complicated and could be made more user-friendly for most users. It is currently not user-friendly for all users. It is good but can be improved. It is a new product, and they are working on it."
"The scanning function could be improved."
"The UI needs improvement as it can become overwhelming after prolonged use."
"Further research and development are needed to enhance integration with other cloud agents and products, particularly improving communication with external products and vendors."
"Currently, in the EASM module, the scan frequency is limited to once daily, but allowing end users control over scan scheduling would be advantageous."
"The main aspect that needs improvement is the user interface, which should be more intuitive."
"Some areas that would be helpful are more comprehensive tagging and the ability to set up better dynamic rules."
"The UI needs improvement as it can become overwhelming after prolonged use."
"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."
"Tenable Nessus is not feasible for a large company."
"Tenable Nessus could improve reporting and information sharing. It would be helpful if we could share the reports and have a little bit better flexibility in the reporting of the data."
"I think the reporting templates could be improved with Tenable Nessus."
"Online learning could be a bit better."
"We'd like to see more integration potential within the solution."
"It would be nice for the professional module to include some of the reports available in the expert module."
"We have had some false positives in the past, which we hope can improve in the future."
 

Pricing and Cost Advice

Information not available
"Qualys CyberSecurity Asset Management can be expensive, especially if we already have VMDR."
"The pricing for Qualys CSAM is nominal."
"It is cost-effective because, in a single tool, we are getting everything. All the solutions come in a single license or price."
"Qualys offers excellent value for money."
"The pricing is market-competitive."
"The cost for Qualys CyberSecurity Asset Management is high."
"Qualys is competitively priced for its features. Its pricing is suitable for large organizations with more than 4,000 assets, but for smaller organizations with few assets, such as banks, the costs might be high. They should come up with packages that are suitable for small organizations."
"The pricing is reasonable relative to the features provided, as it collects all module data and operates as a main, centralized inventory, making it a cost-effective solution."
"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."
"I would like to see better discounts."
"The price is reasonable."
"We incurred a single cost for a perpetual license, although I cannot comment on the price as this is above my management level."
"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 is a free version of Tenable Nessus available."
"The price is high for the solution. There are free tools with similar functionality available. The solution cost approximately $3,500."
"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."
