Malicious Packages Don't Fit the Vulnerability Intelligence Model
By Jenn Gile, Co-Founder, OpenSourceMalware and VulnCon 2026 speaker Monday, April 20th, 2026 When a malicious package appears in a public registry, the response motion looks familiar. A record appears in a vulnerability database (like OSV). Security tools fire an alert. Someone opens a ticket. The workflow feels right because it resembles every CVE remediation cycle that came before it. But somewhere between the alert and the actual response, things start to break down.
WasmCon 2023: A Conversation about the Future of WebAssembly
WebAssembly, often abbreviated as Wasm, is shaking up the open source development landscape. Not only does it improve security with its sandboxed execution, WebAssembly also promotes code reusability by enabling developers to create high-performing web applications in nearly every popular language (C, C++, Go, Ruby, Rust and more) while seamlessly integrating with existing technologies. One thing that became clear during our time at WasmCon: WebAssembly is about improving the developer experience.
A Guide to Navigating Open Source Support Requirements in the US Government
If software is eating the world, then open source is eating software. Linux is the dominant operating system, and progressively more enterprise applications are being built with high percentages of open source code. In response, the U.S. government has prioritized the adoption of open source software (OSS) in federal agencies. Teams in the national security and defense agencies have long been using OSS for cybersecurity and rapid response software-oriented problem-solving.
Why the FDA's SBOM Mandate Changes the Game for OSS Security
The new FDA software bill of materials (SBOM) guidelines for medical devices could have broad impact on the healthcare industry and the broader open source ecosystem. Source: vska via Alamy Stock Photo The US Food and Drug Administration (FDA) is not exactly top of mind for the average open source software (OSS) project maintainer nor the developers building applications that leverage OSS. But new rules from the FDA could impact OSS security more than any government rule to date. The big change?

Microservices and Kubernetes: A Gardening Guide to Software Ecosystems
Like gardening, software development requires an understanding of how different elements work together to create a beautiful, productive ecosystem. That was the catalyst for our choice of a gardening theme for this year’s Microservices March program. As is the case with any garden, one problematic weed keeps creeping into the conversation: what is the difference between microservices and Kubernetes? Plants are the main elements of a garden’s ecosystem.
API Gateway, Ingress Controller or Service Mesh: When to Use What and Why
In just about every conversation on ingress controllers and service meshes, we hear some variation of the questions, “How is this tool different from an API gateway?” or “Do I need both an API gateway and an ingress controller (or service mesh) in Kubernetes?” This confusion is understandable for two reasons: Ingress controllers and service meshes can fulfill many API gateway use cases.

Duplication, Not Consolidation: The Path Forward for Apps
Jenn Gile Jenn is manager of product marketing for NGINX, part of F5, and specializes in modern app development and security using cloud native technologies including Kubernetes and microservices. Originally from Oregon, she now lives in Seattle. With the rise of microservices and the move away from monolithic architectures, IT and DevOps teams have focused on consolidating everything in infrastructure into a smaller and smaller set of platforms and technologies.
How to Choose a Service Mesh
[The blog post titled “Do I Need a Service Mesh?” redirects here.] In recent years, service mesh adoption has steadily moved from the bleeding edge to the mainstream as organizations deepen investment in microservices and containerized apps. The Cloud Native Computing Foundation’s 2020 survey about use of cloud‑native technologies leads us to the following conclusions. Takeaway #1: Service mesh adoption is rising rapidly.
How to Improve Resilience in Kubernetes with Advanced Traffic Management
There’s a very easy way to tell that a company isn’t successfully using modern app development technologies – its customers are quick to complain on social media. They complain when they can’t stream the latest bingeworthy release. Or access online banking. Or make a purchase, because the cart is timing out. Even if customers don’t complain publicly, that doesn’t mean their bad experience doesn’t have consequences.
How to Improve Visibility in Kubernetes
Adoption of microservices accelerates digital experiences, but microservices architectures can also make those experiences more fragile. While your developers are running fast to get new apps out the door, your architecture may be putting you at increased risk for outages, security exposures, and time wasted on inefficient troubleshooting or fixing preventable problems.
Welcome to Microservices March!
What do you get when two plants kiss? Tulips! 🌷🌷 In Seattle (where F5 is headquartered), the month of March is a time of growth fueled by our legendary liquid sunshine. It’s with great re‑leaf that we bid farewell to winter and welcome you to “Microservices March”, a month‑long virtual festival of microservices activities. Whether you’re already using Kubernetes in production or your interest is just blossoming, you’re sure to find sessions that will pique your interest.
Reduce Complexity with Production-Grade Kubernetes
2020 was a year that few of us will ever forget. The abrupt shuttering of schools, businesses, and public services left us suddenly isolated from our communities and thrown into uncertainty about our safety and financial stability. Now imagine for a moment that this had happened in 2000, or even 2010. What would be different? Technology.
Accelerate Cloud-Native Apps with Automation
Since you’re reading this blog, no doubt you’re aware that automation is essential to delivering modern digital experiences. It enables agility at a pace that isn’t possible with human hands, reduces downtime and errors, and lets developers focus on the things that give them joy. 73% of organizations are automating network operations to boost efficiency, and perhaps nowhere is automation more prevalent than in public clouds.
Secure Cloud-Native Apps Without Losing Speed
Organizations are rapidly adopting cloud‑native app delivery – 27% of organizations plan to deploy more than half of their apps in the cloud by the end of this year and by 2022, 35% of all production apps will be cloud native, according to the API management survey that NGINX commissioned from IDC for 2019. The drive to cloud migration and cloud‑native app development unlocks IT agility and exceptional digital experiences for customers.
Announcing the NGINX Core Collection for Ansible
It’s the Year of Ansible at NGINX. We believe in an that enables intelligent scaling of apps at the point of a bottleneck, eliminating the need to scale infrastructure across the entire app. Key in making this approach a reality is the vast ecosystem of CI/CD tools used by developers. As one of the most popular automation tools, Ansible enables NGINX users to quickly automate repetitive tasks across the app lifecycle.
The Value of Red Hat + NGINX
At NGINX (now a part of F5), we’re seeing a shift in what customers expect from their technology providers. We see code as the literal and figurative connective tissue that builds communities, drives innovation, and tells stories. It only makes sense for us to invest in a relationship with another open‑source–loving company known across the globe: Red Hat. NGINX is making one of its deepest investments in optimizing for the Red Hat platforms.
