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.

Empower clients with risk-based vulnerability management through continuous workflow and valuable insights
Tenable Security Center could improve by implementing more dynamic data displays and translating reports into European languages. This is especially relevant in Central Eastern Europe, where clients often require reports in local languages. Additionally, the licensing model could be more flexible for managed security providers, similar to a pay-as-you-go model.

Cloud-based platform simplifies device and data center management
I find it to be good. The solution is cloud-based with the latest inspection engines, which I find to be amazing. We are less dependent on data centers and device management, which reduces our efforts significantly. It improves our device management, data center management, and updating devices. We need fewer engineers for this management, and it reduces time and efforts for data center management, device upgrades, and IT support.

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."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"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."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"We saw benefits from Zafran Security almost immediately after deploying it."
"The tool provides us insight into the happens of the network and its hosts. It provides me with a list of hosts."
"The most valuable features in Tenable SC are scanning and analysis."
"It basically reviews our threat landscape vulnerability."
"The most valuable feature of the product is the Assurance Report Card, which gives us an overview of the security poster in just a simple glance."
"Overall, I rate the solution 9.8 out of 10."
"The solution is completely stable and operation is user-friendly."
"Feature-wise, Tenable Security Center is a very fast tool with many dashboards and reports, and it covers all our systems."
"Tenable also helps us to focus resources on the vulnerabilities that are most likely to be exploited. And since it is continuously updated, it allows us to reevaluate quickly if there are new vulnerabilities found..."
"You can close your data protection gaps with Zscaler. You can quickly find all the classified, sensitive data across the cloud."
"The solution is cloud-based with the latest inspection engines, which I find to be amazing."
"The most valuable feature is its seamless integration capabilities, streamlining the process by eliminating the need for extensive installations."
"With SASE, we have a single platform that covers multiple task services with which we need to control access. All the features are equally valuable."
"Zscaler Cloud DLP provides you with basic DLP features that you get out of the box such as keywords, regular expressions, and data identifiers, for example, your social security numbers, and credit card numbers, with everything built into the product, so you can directly use those features within the policies. You don't need to create it from scratch, and to me, this is the biggest benefit of Zscaler Cloud DLP. You have a lot of templates to choose from in the solution, rather than having to create templates from scratch or reinvent templates."
"Overall, the solution does a pretty good job at web filtering."
"The most valuable features of Zscaler CASB are API integration and DLP."
"The most valuable feature is its ability to establish connectivity for remote users and remote endpoints. It offers a high level of granularity compared to typical VPNs, which also encapsulate a lot of I/O."
 

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."
"Certain aspects require manual effort, such as exporting and analyzing data for our dashboards. The built-in components of the Tenable solution are somewhat clumsy that require external tools. So, this is an area of improvement."
"The product should provide risk-based vulnerability management."
"At times we have had the typical bugs."
"The web application scanning area can be improved."
"The tool's initial configuration is not so easy."
"I will say it's a lot slower compared to an MS scan. It takes so much longer, so the performance could definitely be worked on."
"We did conduct a long implementation which relates to what I think can be improved about Tenable Security Center."
"The web application is not very functional."
"The solution needs to improve a lot of aspects."
"We often face performance and latency issues with Zscaler SASE."
"On the improvement side, when we bypass certain internet traffic types, it's currently recommended to have a one-click option, but audio and video aren't always supported. Thus, we need to bypass that kind of traffic. So, it is an area of improvement."
"The area that requires improvement is their support. The current support is lacking."
"Price-wise, it is a costly product and it should be reduced."
"Zscaler Private Access's reporting is poor. We should have more insight into the reports regarding what is blocked and allowed."
"The solution's granularity should be improved because it has limited granular options to control, visible, allow, block, delay, and receive."
"Zscaler Private Access could improve by improving external access. If external parties want to access locally to my company's services, we need to onboard them into our domain, otherwise, it doesn't work. Additionally, if their company also has Zscaler Private Access, then it doesn't work. They need to log in with our domain ID, not their company ID."
