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.
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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.
OrenBen Shalom - PeerSpot reviewer
Consolidates vulnerability discovery, prioritization, and remediation in a single platform
Vicarius vRx offers several advantages, especially for organizations with diverse operating systems and applications requiring frequent patching. The platform helps prioritize patch installation by identifying high-risk vulnerabilities, allowing IT teams to focus on critical threats first. This prioritization is crucial because it prevents IT teams from being overwhelmed by the constant influx of patches, enabling them to create a manageable plan and allocate resources effectively. By distinguishing between critical, high-risk, and medium-risk vulnerabilities, Vicarius vRx empowers IT teams to address the most urgent threats promptly and schedule less critical patches for later. Both native operating system updates and Vicarius vRx offer vulnerability remediation. Native OS updates allow for the patching of system vulnerabilities on Windows, macOS, and Linux. However, Vicarius vRx provides a single solution for installing both operating system and application updates by also discovering application vulnerabilities. Another valuable feature is virtual patching, which allows us to protect an asset from a specific vulnerability without installing a patch. Sometimes, installing a patch alone is insufficient and requires restarting the asset. However, production servers often cannot be restarted during the day, restricting restarts to specific timeslots. Virtual patching creates a network-based protection layer that prevents exploitation of a vulnerability, offering a temporary safeguard. While not a foolproof solution for long-term use, it's a valuable tool that reduces tension between IT and security teams by providing time to properly install patches.

Quotes from Members

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

Pros

"Zafran has become an indispensable tool in our cybersecurity arsenal."
"Zafran is an excellent tool."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"We saw benefits from Zafran Security almost immediately after deploying it."
"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."
"The initial setup is very straightforward."
"The most valuable feature is the installation of Tenable which is incredibly easy."
"The vulnerability scanner is the most valuable feature."
"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."
"We looked at Tenable, Qualys and Rapid7. We found Tenable was the best of all three."
"Tenable Nessus is cheap and flexible."
"Vicarius vRx has reduced meantime to remediate by 90 percent."
"Vicarius vRx consolidates vulnerability discovery, prioritization, and remediation in a single platform."
"We can easily deploy patches for third-party applications. It automatically downloads the patches for you. You do not have to download them, upload them to the solution, and configure your own scripts or anything like that. It is all automatic."
"The ability to consolidate vulnerability discovery, prioritization, and remediation in one platform is crucial."
"I liked the initial dashboard."
"The system prioritizes vulnerabilities, identifying high, medium, and low risks, allowing us to focus on high-risk applications. It allows us to focus on high-risk applications and do the updates."
"The most valuable features of vRx would be virtualized patching and severity prioritization."
"Patchless Protection helps protect us from vulnerabilities that may not yet have patches from the manufacturer. I've used it for a piece of software that we don't have a patch for. It monitors that software, analyzes it, and makes sure nothing nefarious is going on when it's vulnerable."
 

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 dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"I think the ability to have some enhanced reporting capabilities is something they can improve on, as they have good reports but we have asked for some specific reporting enhancements."
"The reports should be improved in Tenable Nessus. For example, when you are auditing compliance with CIS standards. It provides very poor reports."
"The solution could improve security updates."
"One area with room for improvement is instead of there just being a PDF format for output, I'd like the option of an Excel spreadsheet, whereby I could better track remediation efforts and provide reporting off of that."
"Consumes more system resources when it's running."
"There could be an integration between Tenable Nessus and other Tenable products. It will help us manage all the solutions using one dashboard."
"We have had some false positives in the past, which we hope can improve in the future."
"They could make their reporting a little better."
"In Nessus Professional, the main drawback was that we could have a single-user login password. So it could be better in terms of security."
"We had an outage due to a change Vicarius performed in their system."
"It would be good if there were more login options. At the moment, it sends you an email to verify your email address, and then you can log in. It would be beneficial to have other options for signing in, like MFA or maybe security keys, especially since it is a security product."
"The patchless protection feature is currently difficult to understand and could be made more user-friendly."
"I would like to see more network architecture elements with patches."
"They do have a search function for device names. They already have a list of all our devices, however, if I'm looking for something, sometimes the name does not come up at the top of the list."
"The multi-tenant portal has room for improvement."
"The user interface for deploying patches can be improved, as it appears complicated when launching patches."
"I don't like logging in. The portal could be a better process. You could use some third-party push notification rather than sending an email, waiting for the link to generate, and clicking on it. That would be good. It's somewhat frustrating when I need to log in."
 

Pricing and Cost Advice

Information not available
"Its price is high for Libya. The companies here in Libya don't have the awareness of and a good budget for cybersecurity services. If you want them to go for a product, you need to provide something different. This differentiation is related to the price. They should give about 40% to 45% discount per person on the current cost."
"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 is much more competitive versus other solutions on the market."
"The price of Tenable Nessus could improve, it is expensive."
"Tenable Nessus is affordable."
"Our organization is huge so our license costs $30,000."
"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."
"I rate the product's price seven or eight on a scale of one to ten, where one is low price and ten is high price."
"The pricing is fair."
"The price of vRx seems fair. None of our clients complained about the pricing. They all thought it was reasonable. Once people understood what it does, it didn't take much to get them to sign up."
"The pricing is great because we are a reseller of the product. It is really up to us and Vicarius, and they are very easy to work with."
"The pricing was very reasonable and fair compared to other products. I liked that there was no tiered system. One price gave access to everything, which is nice. It is not something you get too often with enterprise IT."
"In the past, Vicarius vRx was cheap, but now they have adjusted their pricing policy, resulting in higher renewal costs. We have had some conversations with them regarding a smaller jump in the renewal cost."
"Vicarius vRx's per-asset pricing makes it easy for me to market to clients as it scales with their needs."
"I know we got it for a very cheap price, and I now see why. It was very cheap. It was maybe 12,000 or 14,000 dollars."
"From a pricing perspective, Vicarius was cheaper compared to other competitors."
