SSH ProxyJump at Scale: Where It Breaks Down and What to Do Instead

Most engineers meet SSH ProxyJump the same way: a single bastion host stands between the public internet and a private network, and one clean -J flag replaces a clunky chain of manual hops. For small teams managing a handful of servers, it feels like a solved problem. But infrastructure grows, teams grow, and the assumptions that made ProxyJump elegant at ten servers start to strain at ten thousand. What works cleanly in a small environment often becomes a liability in a large one, and understanding why is the first step toward finding a better approach.

Beyond IP addresses: How DDI solutions power telco data center operations

There is a moment, somewhere between the third ring of a phone call connecting and the first frame of a video buffering, where an entire telco data center has already done its job. A device asked a question, Where do I belong, and what is my name here? And somewhere in a rack of servers, in less time than it takes to blink, the system gave the answer.

The EU AI Act Is Here. Is Your AI Environment Ready?

AI has moved from experimentation to operational reality. Last year saw a 50% rise in access to AI for employees, with 88% of organizations using AI in at least one business function. Competitive pressure is accelerating AI adoption. While this creates opportunity, it also creates a new level of operational risk.

Ten Black Hat NOCs and counting: Corelight sees it all

Whenever I come back from a Black Hat NOC, people always ask the same question: “So, what did you see?!” They understand how unique it is to have access to the detailed logs generated by an NDR overseeing the network traffic of a conference with thousands of attendees. There is always something to see. There are always stories that come out of the packets; those stories evolve into patterns, and the patterns offer the gift of lessons.

What Is Firewall Configuration and Why Is It So Important?

Firewall configuration is the set of rules, policies, and settings that define how a firewall behaves. Without configuration, a firewall is hardware and software waiting for instructions. With configuration, it becomes a control that determines what traffic is permitted, what is blocked, and what gets inspected before a decision is made. Get the configuration right, and the firewall does its job. Let it drift, and you have the appearance of protection without the substance of it. This is not an edge case.

Rethinking the Interception Proxy: Why Crusader is Betting on Local-First SQLite

For years, interception proxies have largely followed the same formula. Capture traffic, display requests, allow replay and modification, and store everything inside an internal project format. It is a workflow that has served penetration testers and bug hunters well, but it also creates an unexpected limitation: the data you generate during an assessment often becomes surprisingly difficult to use outside the proxy itself.

Tiered Network Policy: Scaling Kubernetes Security

As Kubernetes clusters scale from a few development sandboxes to massive, multi-tenant production environments, platform teams often find themselves facing a configuration management crisis. A small number of microservices suddenly demand hundreds of individual Kubernetes NetworkPolicy objects. Managing them becomes operationally expensive, auditing them is difficult, and a single developer misconfiguration can easily drop critical production traffic or open a massive security hole.

Cloud Transition Challenges: From On-Prem to Multi-Cloud Security #shorts

Organizations are fully onboarded in multi-cloud environments (AWS, Azure, GCP), but transitioning from traditional on-prem security to the cloud poses a significant challenge. Cloud security teams now need to collaborate with traditional network engineering teams, each with different objectives, to bridge the gap.
