Insights from Talos and Splunk on Cybersecurity in 2025

Summary: Cisco Talos and Splunk review the main threats of 2025, focusing on the professionalization of ransomware-as-a-service and the persistence of old vulnerabilities.

Cisco Talos and Splunk transform their respective balances of 2025 into a conversation that helps to order the threat landscape beyond today's headlines. The discussion focuses on an uncomfortable but already familiar combination: increasingly professionalized ransomware-as-a-service, alongside organizations still dragging exposure from old vulnerabilities, technical debt, and difficulties in prioritizing defenses.

The value of this piece lies in its practical approach. Rather than limiting itself to describing trends, the analysts connect findings from their reports with operational lessons for defensive teams. The reading suggests that while cybercrime sophistication and market dynamics are adopted, much of the damage still relies on known vulnerabilities, insufficient visibility, and slow response times.

As context, it works well because it synthesizes the year without losing utility. It does not attempt to amplify a single threat but shows how different pressures—ransomware, persistent old vulnerabilities, and poorly managed surfaces—converge into the issues that truly mark the security agenda.
