Advanced protection enables us to confidently secure against evolving threats
Palo Alto Networks can improve Advanced Threat Prevention by catering to the growing adoption of AI and agentic tooling. The Threat Protection modules should have the necessary intelligence to protect against those types of threats, as AI will be there to do a human job; this is an evolving area. From an Advanced Threat Protection perspective, the technology associated with Palo Alto Networks, such as their sandboxing environment, is quite good. However, Palo Alto needs to focus on how to bring that technology to end users and how easy it is to use, especially in a hybrid environment where users work from various locations. While Palo Alto excels in certain setups, they need to improve the user experience in distributed working conditions.

Has improved email security through advanced filtration and timely threat detection
I work with Trend Micro Apex One. I have used the Deep Discovery's Sandbox analysis feature, and we utilize another appliance known as Deep Discovery Analyzer, abbreviated as DDA. This tool makes analysis for URLs and attachments contained in inbound emails, so whenever we receive an email with a URL or attachment, it will be analyzed by Trend Micro Deep Discovery Analyzer. In evaluating Deep Discovery's real-time visibility on network traffic, it is important to note that we applied our Deep Discovery Analyzer for Trend Micro to conduct sandboxing specifically for email channels only, and we do not utilize it for network channels. For network channel sandboxing, we use a solution called FortiAnalyzer, which belongs to another team called network security. I assess Deep Discovery's effectiveness in identifying sophisticated attack patterns by looking at how it handles high traffic loads, and how effectively it can use its instances and images to analyze numerous URLs and attachments simultaneously. Additionally, I evaluate its ability to maintain round-robin or load balancing across different analyses without leaving samples queued for analysis. The performance is critical when the product updates for signatures are up-to-date, as this aids in the detection and classification of URLs and attachments without delay in the analysis process. On a scale of one to ten, I rate Trend Micro Deep Discovery a nine.
