In this special Year in Review episode of This Week in NET, host João Tomé is joined by David Belson to break down the Cloudflare Radar 2025 Year in Review. Together, they explore what Cloudflare’s global network reveals about how the Internet evolved over the past year — from the rapid rise of AI crawlers and agent traffic, to record-breaking DDoS attacks, the spread of post-quantum encryption, and the growing impact of government-directed shutdowns and outages.

Powered by the industry’s most comprehensive cyber risk data, Bitsight helps security and GRC teams respond faster to critical threats—including zero-day vulnerabilities—while improving vendor collaboration and strengthening overall supply chain resilience.

In November 2025, AppTrana detected 227 zero-days and blocked every single one. Explore the full report to see how complete coverage looks.

In November 2025, a major public-private sector collaboration took down three significant malware networks. Operation Endgame involved law enforcement agencies from six EU countries, Australia, Canada, the U.K., and the U.S., along with Europol and 30 private sector partners, including CrowdStrike. The dismantled infrastructure consisted of hundreds of thousands of infected computers containing several million stolen credentials.

In Episode 4 of Corelight Defenders, I sit down with Angela Loomis, Corelight's Director of Technical Account Management, to explore her remarkable 25-year journey in cybersecurity. Angela shares her unconventional entry into the field, starting from a background in television production to becoming a leader in security strategy. We delve into the importance of curiosity in cybersecurity, discussing how diverse experiences enrich the profession, and whether formal education might dampen that curiosity.

What really happened in cloud security in 2025 and what should security leaders prepare for in 2026? In this session, cybersecurity leader, Shira Rubinoff breaks down the biggest cloud security challenges organizations faced in 2025, why cloud misconfigurations and IAM complexity are still major risks, and how CISOs should rethink cloud security strategy and budgeting for 2026.

Containers are supposed to be isolated — but what happens when that isolation breaks? In this video, we explain critical container escape vulnerabilities in runc, the default container runtime used by Docker and Kubernetes, and why they represent a serious container security risk. Recent disclosures known as the “Leaky Vessels” vulnerabilities show how a compromised container can escape its sandbox, access the host filesystem, and potentially take over the node.

Drowning in threat data? You’re not alone. Bitsight Pulse turns overwhelming intel into clear, actionable insights — so you can see what matters and skip what doesn’t.
