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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Zafran is an excellent tool."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"Scanners and reports using CIS templates ("de-facto" standard, easy to fix and to locate correction tips at documentation), tests against cloud providers, database profiles, several types of telecom devices, and others highly customizable scans."
"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 most valuable features of Tenable Nessus are the scanning option. Advanced scanning is highly useful. The offline config audits and application assessments are useful."
"It gives a holistic view of your entire environment."
"User friendly and good dashboards."
"We have done code scanning for a long period because as a company, we do DevOps as part of our development life cycle."
"You can then direct your team to create a report on the discovered vulnerabilities."
"Tenable integrates well with other solutions such as SIEM and batch management."
"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."
"Vicarius vRx offers several advantages, especially for organizations with diverse operating systems and applications requiring frequent patching."
"The ability to consolidate vulnerability discovery, prioritization, and remediation in one platform is crucial."
"The prioritization of the vulnerabilities and patches that we must apply immediately is valuable. The automation of the tasks allows us to spend less time in that area."
"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."
"Vicarius vRx's primary strength is its user-friendly interface."
"vRx seemed to be user-friendly and very easy to use."
"The dashboard is quite easy to manage. The automation aspect is also very valuable."
 

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 inventory management function in this solution needs improvement."
"From my point of view the solution basically is not for the big enterprise."
"The problems I faced with Tenable Nessus were related to its dashboard's customization capabilities and its ability to provide data to third-party sources."
"Tenable Nessus could improve the reporting by adding some dashboards. The reports are a hassle at this time. Tenable.io has more detailed reports. Having a better dashboard that can show where the vulnerabilities are and be categorized would be helpful. We then could present them to upper management for a deep overview of our network posture which they do not see."
"Tenable Nessus could include a broader range of IT assets."
"The reports are okay, but the interface is a bit difficult to navigate in some cases."
"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 improve the price."
"I would be happy if the patch update could be downloaded to the Vicarius server and then implemented on the client. Currently, they just send a link to the software."
"The patchless protection feature is currently difficult to understand and could be made more user-friendly."
"The patchless protection feature is currently difficult to understand and could be made more user-friendly."
"Areas that need improvement include the CPU usage and the delay between sending updates and receiving feedback on their status."
"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."
"We had an outage due to a change Vicarius performed in their system."
"I would appreciate additional filter options, such as the ability to filter by AWS tags."
"Another complaint we've gotten is that the portal doesn't remember your username and password. You tell them your email, and it sends an invitation. You need to click that, and it takes you to a new portal, where you can finally log in. Maybe it's a security precaution, but it seems like a lot of extra steps to log in."
 

Pricing and Cost Advice

Information not available
"This solution is affordable."
"The solution has a single price for unlimited assets."
"Our organization is huge so our license costs $30,000."
"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."
"Nessus Manager is not an expensive product. It has its limitations, but the pricing reflects that. We have a yearly subscription."
"One problem with Tenable is its pricing policy. Optimal results can be achieved with Greenbone Solutions which has much more friendly pricing policies."
"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."
"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."
"The pricing is fair."
"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."
"Vicarius vRx offers a competitive price point for the features it provides."
"I am not sure how much it costs, but it would have saved us some costs."
"It is in the middle. It is not the cheapest solution, but it is also not terribly expensive. We found it to be a good fit. It is fairly priced."
"Vicarius vRx is reasonably priced."
