When a user connects to a website or application over HTTPS, the traffic between them is encrypted. That protects the data in transit, but it also creates work: somewhere in the infrastructure, the traffic has to be decrypted before the application can actually process the request. In a simple setup, each application server handles that…

Modern Application Delivery Controller (ADC) deployments rarely operate in simple networks. Enterprise environments commonly include multiple VLANs, routers, firewalls, gateways, backend networks and redundant paths. At the same time, application servers are increasingly interconnected: a server can be the backend of one load-balanced service while simultaneously acting as a client consuming another Virtual IP (VIP).…

An HTTPS request can pass every network-level check and still contain something your application should never process. SQL injection, malicious JavaScript, malformed HTTP data or a dangerous file upload can all travel inside what appears to be a perfectly valid connection. This is exactly where a Web Application Firewall comes into play. The interesting part…

Choosing infrastructure technology has traditionally involved a familiar set of questions. Does it meet the technical requirements? Will it handle the expected traffic? Is it compatible with the existing environment? What will it cost to deploy and maintain? Security teams are adding another question to that process: how much do we know about the company…

Security vulnerabilities in Internet-facing infrastructure call for a clear operational response: determine whether your environment is exposed and, if it is, apply the vendor's remediation. The recent NetScaler vulnerability CVE-2026-8452 is no exception. NetScaler describes it as a memory overflow affecting ADC and Gateway appliances under specific Gateway or AAA configurations. Subsequent independent security research…

Choosing a load balancer is not only a technical decision. It is also a decision about how much infrastructure your organization wants to deploy, maintain and operate. Some companies need complete control over the underlying application delivery infrastructure. They may prefer physical appliances, virtual appliances, bare-metal deployments or software running inside their own cloud environment.…

A Moodle deployment that performs flawlessly with 20,000 users can easily collapse under the load of 100,000 users on exam day or when course registration opens. The issue isn't Moodle itself. It's that, in a single-server deployment, everything (the web application, user sessions, database, and uploaded files) runs on the same machine. Once that server…

Modern applications generate more traffic, serve more users, and depend on more distributed infrastructure than ever before. Whether you are running a SaaS platform, an e-commerce website, a banking application, or a public API, ensuring traffic reaches the right resources efficiently is critical for performance, availability, and security. This is where load balancing plays a…

Some attacks steal data. Some attacks spy on users. And some attacks have only one goal: to make your service unavailable. DDoS attacks fall into the latter category, and they are more common and more accessible to attackers than many organizations realize. They don't require exploiting a specific vulnerability or gaining access to internal systems.…
