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.

Has improved real-time threat detection and unified cloud protection through AI and automation
Cortex Cloud by Palo Alto Networks is creating some confusion in terms of names because this is recent. They changed the names of the products and are now clarifying their offer. The family of the products is not easy to follow because it's very recent. Regarding the generative AI security tool, I know for sure it's Agentic. Based on my experience with Palo Alto, I can suggest what Cortex Cloud by Palo Alto Networks could make better or what additional functions could be added. This is the best tool in the market. It's not the time to tell what they could do better because it's a recent tool. The market is now adopting it. Our experience doesn't show that they need to do more.

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.

Pros

"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."
"We saw benefits from Zafran Security almost immediately after deploying it."
"Zafran is an excellent tool."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"I have seen several benefits from using Cortex Cloud by Palo Alto Networks: It was easy to use and easy to migrate from the IBM platform."
"I have absolutely seen improvements in our incident close rates, with mean time to detect and respond reduced significantly, sometimes by at least forty to fifty percent."
"The AI and automation features in detecting and responding to high-risk threats are impressive; it's one of the best tools regarding AI technology and unifies security in one platform in real-time, improving vulnerability analysis, incident response, and compliance reporting."
"Cortex Cloud by Palo Alto Networks has impacted our organization positively by keeping our machines secure and our team using the dashboard to find issues quickly."
"Overall, Cortex Cloud by Palo Alto Networks is a technically strong product, and I rate it ten out of ten."
"We use Tenable to scan all of our environments and plugins for vulnerabilities. Tenable helps us discover network vulnerabilities to threats and piracy."
"The most effective feature of Tenable Security Center for detecting vulnerabilities is its capability for critical mapping."
"The usability is really good. It's very easy to use and a good platform. It is scalable and very stable. The technical support is fine and the setup is super easy."

"Some aspects of the GUI can be confusing and make it difficult for me to find certain options or navigate where needed."
"The solution needs to improve the vulnerability assessment because we have experienced some challenges with accuracy."
"The vulnerability scan does not work correctly until the access privileges are set by the system administrator."
"Security can always be improved."
