In this special, end-of-year episode (and Hazel’s final show as host) Talos Takes goes on a time-travel adventure: What would a defender from 2015 think of the cybersecurity realities of 2025? Joined by Talos teammates Pierre Cadieux, Alex Ryan, and Joe Marshall, we compare the threats, tools, and challenges of 2015 with those of 2025. The team recalls where they were in their careers a decade ago, then dives deep into how ransomware has evolved, how APTs and state sponsored attacks have shifted, and why identity has become the new battleground for attackers and defenders alike. They discuss the impact of AI on both sides of the security equation, share what they miss from “the good old days,” of 2015, and offer practical advice for defenders facing the challenges of 2026 and beyond.
What happens when your to-do list keeps growing but your budget doesn’t? Hazel is joined by three Cisco Talos Incident Response experts to talk about the reality many organizations face: rising threats, aging infrastructure, and fewer people to defend it all.From configuring what you already have, to open-source strategies, to the impact of cybersecurity layoffs, this episode is packed with practical guidance for securing your organization during an economic downturn.Resources mentioned:https://blog.talosintelligence.com/cybersecurity-on-a-budget-strategies-for-an-economic-downturn/https://blogs.cisco.com/news/doubling-down-on-resilient-infrastructurehttps://talosintelligence.com/incident_response
