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.
