What are the core features and capabilities of the leading Security Orchestration, Automation, and Response (SOAR) platforms discussed in the article, and how do they help security teams automate repetitive tasks, orchestrate multiple security tools, and standardize incident response workflows? How do the pros and cons of platforms such as Cortex XSOAR, Splunk SOAR, IBM Security SOAR, and Rapid7 InsightConnect influence which solution is best suited for different Security Operations Centers (SOCs) or enterprise environments? In what real-world scenarios—such as phishing response automation, malware containment, threat intelligence enrichment, and vulnerability management—would one SOAR platform deliver better efficiency, scalability, or integration than others?
