Has become an indispensable tool in our cybersecurity arsenal
While Zafran Security is already a powerful tool, there are areas where it could be further improved to provide even greater value. One key area for enhancement is the searching capabilities within its vulnerabilities module. By incorporating the ability to create Boolean searches, users would gain the ability to apply more complex filters and customize their search criteria. This would greatly enhance the precision and efficiency with which security teams can identify and prioritize vulnerabilities. Having such tailored search capabilities would save time and resources by narrowing down vast lists of vulnerabilities to those that meet specific parameters relevant to our unique risk environment. Additionally, integrating more robust reporting and visualization tools would be advantageous. Enhanced dashboards that offer customizable visual representations of risk configurations and threat landscapes would facilitate better communication with stakeholders, making it easier to explain vulnerabilities and the rationale behind certain security measures. This would also aid in demonstrating the improvements and value derived from existing security investments to leadership and non-technical team members.

Passive scanning excels and support proves invaluable
Regarding the cons of the Claroty Platform, it is not about the deployment, but rather the identification. The Claroty Platform becomes too noisy when it gives numerous CVEs related to vendor match. Sometimes, these CVEs are not actually related to the device in the firmware at the site. The Claroty Platform identifies effectively but sometimes identifies many CVEs which might not be the actual issue in certain scenarios.

Has unified our IT teams by providing clear visibility into network vulnerabilities and accelerated remediation with real-world attack testing
One of the things that we've shared with Horizon is just the reporting. They've made a lot of changes over time, but when examining computers, most average normal people don't look at a computer and identify it as 114.82.117.180. They identify it as 'the printer for accounting.' When many of the reports give the very detailed technical IP address or serial number, that's really not helpful for anyone other than the person, the hands-on person that's trying to remediate it. All the managers, all the leaders, having information in that format isn't helpful. Being able to have information about what those devices are would be very helpful. There's a technical reason they can't just have an easy button because some people have really complicated networks. When examining things for the average company, the average executive, that 114 number, there's only one of those. But if examining an AT&T or a Walmart, it isn't unique. They haven't solved that problem. But for the 90% of companies, being able to have just a human readable name for all devices on your network in all of the reports all of the time would be the most beneficial.

Quotes from Members

Pros

"Zafran has become an indispensable tool in our cybersecurity arsenal."
"With Zafran Security, it integrates with your security controls, allowing you to take that risk score and reduce it based on the controls in place or increase the risk based on different factors, such as if the issue is internet reachable or if there's an exploit in the wild."
"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."
"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."
"Their SRA solution, the Secure Remote Access solution, is very useful for industrial environments."
"I appreciate the active coding, deep inspection of packages, and data retrieval. The tool covers information about assets and attack vectors, which I find superior to other tools. Based on alerts, I create reports detailing how an attacker can penetrate the plant, both externally and internally."
"Claroty is very beneficial for learning and adds value to your resume."
"The solution offers comprehensive tools that greatly enhance your IT operations if implemented correctly."
"The product helps mitigate potential threats, especially if its users have signature rules. The product also provides alerts."
"The platform ensures security without imposing significant delays."
"Claroty provides continuous threat protection and identifies pre-empty stuff and false positives."
"I have had a very good experience with the Claroty Platform."
"The NodeZero Platform's real attack capabilities help identify vulnerabilities on my on-premise systems by adding an element of validation and offensive security testing on top of known vulnerabilities. The feature that allows security teams to fix and retest vulnerabilities instantly is very useful, even though it may not happen literally 'instantly.' It's a necessary tool for any organization to understand whether vulnerabilities are genuinely exploitable by attackers. With its near-real-time testing capabilities, it's an essential part of any security portfolio."
"Overall, I'd rate NodeZero at nine to 9.5 out of ten."
"For us, The NodeZero Platform is literally the single best security solution we have because the way that it works is we're able to scan every part of our network, both internally and externally, and then get completely actionable feedback that doesn't matter if it's for an application developer or a network admin."
"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."
"Honestly, it's one of the most transformational technologies we've implemented in our company."
"I rate the stability of the NodeZero Platform a ten out of ten."
"The NodeZero Platform's real attack capabilities help in identifying vulnerabilities on our on-prem systems because it provides actual vulnerabilities by attacking our systems."
"My favorite feature about The NodeZero Platform is that it's autonomous, and it truly delivers on that promise—it can be set and forgotten while it performs its tasks, and it does exactly what it claims to do."
 

Cons

"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"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."
"There is room for improvement in the user interface to make it more vibrant and interactive, similar to IT tools."
"There is room for improvement in the user interface to make it more vibrant and interactive, similar to IT tools. Improvements could also be made in the Secure Remote Access (SRA) user interaction and graphical representations of recordings."
"Introducing an AI chatbot to assist you when you have doubts could be beneficial."
"Claroty Platform only gives the vulnerabilities based on the make and model of the devices, so it doesn't provide any resolution or any detailed explanation of how one can resolve such issues."
"I think the only issue is that the hardware Claroty uses is expensive."
"If more AI features could be included with the Clarity solution, it would be feasible for everybody."
"The product's integration capabilities are an area of concern where improvements are required."
"For improvement, I think the training could be more practical. We have external training, but they're mostly theoretical. I want the solution to provide hands-on lab experience to help users learn better."
"The only issue we’ve encountered is that sometimes the scans take a long time to complete."
"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 speed of the scans takes some time, but in my opinion, it is not surprising for what it is doing."
"They've added a chatbot which isn't particularly useful, but when it can't answer questions, it forwards messages to human support."
"One of the areas where improvement is needed is in the visibility and reporting for large enterprises."
"You need to be cautious about what it scans, as it could potentially cause issues."
"I think The NodeZero Platform could improve by leveraging GPUs for password cracking, which would be pretty good."
"The reports are quite useless."
