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.

Has enabled me to reduce false positives and perform deep credential auditing with seamless integrations
I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature. Regarding integration capabilities, we can integrate Tenable Nessus with SIM tools such as Splunk, IBM QRadar, and Azure Sentinel, as well as with ticketing systems such as ServiceNow, Jira, and Slack. There is no complexity as it is very easy to integrate everything. In terms of the reporting feature, while vulnerability scanning can throw some false positives, Tenable Nessus has very few, achieving a reduction of 75% to 80% false positives with manual analysis needed. We can generate standard Nessus reports that typically include host summaries and vulnerabilities by host and plugin, alongside solutions and remediation recommendations. The main benefits I get from Tenable Nessus are complete asset inventory and comprehensive attack surface management, allowing us to prioritize vulnerabilities based on risk, focusing on true risk and threat path analysis.

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 is an excellent tool."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"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 saw benefits from Zafran Security almost immediately after deploying it."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"The most valuable feature of Tenable Nessus is the self-updating engine."
"Among the most valuable features are scanning for vulnerabilities and the reporting. The reporting templates are okay. I like that I can see all the hosts with different vulnerabilities."
"The solution provides time saving and cost saving benefits."
"The trial version is very good for testing whether it will suit your needs."
"Tenable Nessus has provided increased visibility across the organization's servers."
"It gives a holistic view of your entire environment."
"It notifies us of vulnerabilities as they arise, allowing us to respond quickly without manual intervention."
"We have done code scanning for a long period because as a company, we do DevOps as part of our development life cycle."
"The most valuable features of vRx would be virtualized patching and severity prioritization."
"Vicarius vRx's primary strength is its user-friendly interface."
"Since we started using Vicarius vRx, I have not had to worry about patching the software."
"Vicarius vRx has reduced our mean time to remediate vulnerabilities by 20%."
"Vicarius vRx consolidates vulnerability discovery, prioritization, and remediation in a single platform."
"Agent-based scanning is the most valuable feature."
"vRx seemed to be user-friendly and very easy to use."
"Vicarius vRx has reduced meantime to remediate by 90 percent."
 

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."
"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 dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"In terms of what could be improved, I would say its reporting portion."
"They should try to create an all-in-one solution."
"The tool needs to upgrade asset tracking."
"The most that Tenable Nessus could improve is its speed because they might have put a lot of effort into compatibility issues that downgrade the speed."
"The reporting is a bit cumbersome."
"The reports should be improved in Tenable Nessus. For example, when you are auditing compliance with CIS standards. It provides very poor reports."
"It would be a good idea if they have a simulation of attacks or a use case for finding a new vulnerability or dealing with a zero-day attack."
"The features are limited when it comes to scanning network devices for vulnerabilities."
"We did some automation. We kicked off scheduled updates to update our systems, but it did not work. When we attempted to scale the product and update multiple systems, we ran into a lot of issues. We also ran into the issue of it creating double assets."
"While I appreciate the automation of vulnerability management, Vicarius vRx's current manual patchless application is a point for improvement."
"I would like to see a way to build a virtual environment where we can test patches in real-time before we deploy."
"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."
"There can be more scripting capability and more filtering capability. We should be able to filter more granular details in the operating system such as whether it is a service, application, executable, or something like that. For the most part, we are satisfied with what we are able to filter."
"The multi-tenant portal has room for improvement."
"Areas that need improvement include the CPU usage and the delay between sending updates and receiving feedback on their status."
"The patchless protection feature is currently difficult to understand and could be made more user-friendly."

"We have a subscription, the licensing fees are paid yearly, and I am using the latest version."
