Why Written AI Policies Alone Won't Protect Your Organization
Most organizations have responded to the rapid growth of AI by creating written policies that define acceptable use. A clear AI policy can establish expectations, assign responsibilities, and help employees understand how AI should and shouldn’t be used. But policy alone can’t provide oversight and is almost impossible to enforce at scale without the right tools.
Public mTLS client-auth certificates stop renewing in October
Chrome’s root program decides what certificates will be trusted by Chrome, and what they are allowed to do. Recently, Google decided that client authentication isn’t on the list. Under Chrome Root Program Policy v1.8, every certificate issued on or after March 15, 2027 can assert only one Extended Key Usage (EKU): server authentication. Let’s Encrypt moved early.
What's New in DX NetOps Topology: Summer 2026
Your enterprise network is more distributed, diverse, and complex than ever before. Your campus, WAN, data center, and SD-WAN environments span multiple technologies and vendors. Now more than ever, the complex relationships between devices, interfaces, and network layers are critical to your day-to-day operations. When an issue arises, knowing that something is wrong is only the beginning.
DNS Alerts over Syslog: TLS, CEF, and a Straight Line to Your SIEM
Enterprise teams can now add a Syslog alert channel: every DNS Spy alert delivered as an RFC 5424 message over TLS (or TCP/UDP), formatted as JSON or ArcSight CEF, with syslog priorities mapped from real alert severity. All deliveries originate from one documented static IP, so getting through your collector's firewall is a single allowlist rule.
Why eBPF Is Useful for Watching and Sandboxing AI Agents
Most of our runtime security habits were built for deterministic workloads. A service does what its code says: review the code, sign the image, and its behavior is bounded. Agents are different. An agent’s behavior emerges from a model reasoning over whatever lands in its context window, and some of that context comes from places we don’t fully control — a retrieved document, a tool’s output, a user’s prompt.
Firewall High Memory Usage: How to Troubleshoot and Fix It
A firewall running low on memory rarely fails all at once. It degrades first. Connections drop intermittently, policies take longer to process, and by the time the device becomes unresponsive, the problem has been building for days or weeks. This article walks through what firewall memory usage actually means, what causes it to climb, how to spot the symptoms early, and how to troubleshoot and fix it before it takes your network down with it.
It was surprisingly hard to break CloudNativePG replication
I wanted a Postgres replica that falls behind its primary. Sounds easy. It wasn't. Every time I cut the replica off from the primary, its lag jumped for a moment and then dropped right back to zero. It just would not stay behind. Chasing down why turned into a fun little tour of how a Postgres standby keeps itself alive, and what CloudNativePG quietly sets up behind the scenes.

Measuring Digital Marketing Performance Like an Ops Team
When your marketing teams start thinking like an Ops team, you can change how you manage campaigns. Instead of just reacting to things, they can use data to make smart choices, keeping things stable and aiming for the best results.

We spend money more effectively, get more conversions, and build a marketing system that delivers predictable results.
