February has seen multiple container security incidents disclosed, continuing a trend that security researchers have been tracking since mid-2025. The common thread in these incidents is not the …
Hybrid cloud segmentation remains the hardest problem in network security. This week, several organizations shared their deployment lessons at industry forums, and the common thread is clear: the …
New zero trust adoption statistics published this week confirm what practitioners have suspected: the gap between zero trust intent and zero trust implementation is widening. While 78% of …
Super Bowl weekend is one of the highest-traffic periods of the year for online streaming, sports betting platforms, and social media. For organizations that serve these sectors — or any …
Kubernetes security trends for 2026 are converging on a single point: native NetworkPolicy resources are necessary but not sufficient. As clusters grow past a few hundred pods, the limitations of …
January’s cloud security budget announcements are rolling in, and one line item is appearing consistently across enterprise IT plans: microsegmentation. After years of being a …
If your network is flat, one breach can reach everything. Microsegmentation is the answer — it breaks your network into isolated zones so a compromise in one area can’t spread to another. This …
January is when security teams emerge from the holiday freeze to face a familiar beast: the CVE backlog. December typically sees reduced patching cycles, delayed change approvals, and skeleton crews. …
