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.
Brian W. - PeerSpot reviewer
Effectively prioritizes vulnerabilities and has been one of the most transformative technologies
Prioritization is really key; it's a massive differentiator. The prioritization aspect is crucial. The ability to capture or crack credentials and then use that to move laterally and identify additional vulnerabilities is significant. Their password-cracking capability is a distinct function that is very helpful. Additionally, when a new vulnerability, such as a zero-day exploit, is identified, they review your previous scans to determine if you might be vulnerable to it, and they proactively notify you. That's a huge benefit. Also, the fact that they provide fixes alongside all their identified vulnerabilities means you don’t have to search for fixes yourself. They give you specific actions to take, which is incredibly helpful and saves a lot of time.

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 saw benefits from Zafran Security almost immediately after deploying it."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"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."
"The NodeZero Platform is amazing; what I love most about it is that it's automated and comparable to the manual pen testing we did with a third-party company, but with the added benefit of unlimited retesting to validate fixes."
"Horizon 3's capabilities are unique, with insights and reporting that provide transparency with offensive security or red team tools the system calls."
"Honestly, it's one of the most transformational technologies we've implemented in our company."
"Overall, I'd rate NodeZero at nine to 9.5 out of ten."
"We experienced a threat that could have severely crippled us, but we were able to shut it down before it escalated, thanks to internal vulnerability testing and addressing critical vulnerabilities using their tool."
"Penetration testing and scans are useful features."
"I rate the stability of the NodeZero Platform a ten out of ten."
"The ability to consolidate vulnerability discovery, prioritization, and remediation in one platform is crucial."
"While other vulnerability scanners overwhelm us with a huge list of problems after a scan, Vicarius vRx goes beyond that."
"I like that vRx is cloud-based. It protects the health of applications against zero-day threats."
"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."
"I liked the initial dashboard."
"Vicarius vRx has reduced 70% of the time we spend on patching."
"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."
"Agent-based scanning is the most valuable feature."
 

Cons

"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."
"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."
"You need to be cautious about what it scans, as it could potentially cause issues."
"The only issue we’ve encountered is that sometimes the scans take a long time to complete."
"One of the areas where improvement is needed is in the visibility and reporting for large enterprises."
"I encountered challenges with patch management, as we struggled to test and implement patches due to time constraints. This led to our patch management process being ineffective."
"The reports are quite useless."
"The rooms for improvement for The NodeZero Platform can be numerous, and they can enhance user experience."
"Based on the request from our clients, it would be great to have an MDM solution. If they can manage vulnerabilities on mobile devices too, that would be great. Having scripting capabilities on mobile devices would be very useful. That was the request we had from lots of clients."
"The patchless protection feature is currently difficult to understand and could be made more user-friendly."
"It would be beneficial if Vicarius vRx could implement smart tagging or suggest tags to create a group for these development tools, signifying that they should not be regularly updated."
"We had an outage due to a change Vicarius performed in their system."
"We are now in the process of trying to get our money back because the tool does not work."
"The network device vulnerability scans can be improved. It would be helpful to be able to mitigate those vulnerabilities using SSH or SNMP to get those those updates out to those devices. I don't know if that is possible because it doesn't run an agent. But at the very least, having that CPE information relative to network devices would be incredibly helpful."
"In the past, Vicarius vRx was cheap, but now they have adjusted their pricing policy, resulting in higher renewal costs."
"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."
