Secure every commit to production with Claude and GitLab
Agentic coding is moving faster than many enterprise governance programs can keep up with. Coding assistants, like the Claude security guidance plugin and Claude Security, can flag and fix common vulnerabilities in code as it's written, in the same session. This is valuable for writing more secure c...
Tailscale didn’t stop the Hugging Face intrusion
Tailscale wasn’t exploited. We still should have stopped the intrusion.
Don’t stop early: Case-folding source code at memory speed
How a branch-free loop and byte-space arithmetic let GitHub case-fold every byte of code search at >45 GiB/s on a single core. The post Don’t stop early: Case-folding source code at memory speed appeared first on The GitHub Blog .

Consul + CyberArk WIM: External CA for the service mesh
Consul Enterprise 2.0 lets you use CyberArk Workload Identity Manager as an external CA for the mesh, anchoring trust in PKI your security team already governs.
How to govern agentic AI, MCPs, and AI code assistants
AI code completion built human review into the process by design. A developer types, a suggestion appears, and a human decides whether to accept it. A person looked at every line before it shipped. Agentic AI breaks that review loop. An agent can open a merge request, call a tool, modify a CI/CD con...
Prioritize security findings with the Datadog Runtime Prioritization Engine
Learn how the Datadog Runtime Prioritization Engine infers ownership and identifies business-critical resources to help you prioritize security findings.
How to build a trust platform for your agent with Grafana Agent Observability
Observing fast-growing agentic workloads is no small feat, especially if you try to build your own monitoring stack or rely solely on tools built for a time before LLMs. At Grafana Labs, we know this all too well. Grafana Assistant went from an internal hackathon project to generally available in a ...
How the controller-runtime Cache Actually Works, and Why Your Controller Does Not Crash the API Server
This article has been revised since it was first published, to correct several significant technical inaccuracies in the original text. Kubernetes has long been the default platform for distributed workloads, and writing your own controller for it is now a matter of a few hours. The common path — Go...
Tame Dependabot: Group your updates, slow the cadence, keep security fast
Dependabot keeps your dependencies current, but its defaults can flood your repository with pull requests. Here's how grouping updates, slowing the cadence, and keeping security fixes fast cut the noise on a Microsoft open source project. The post Tame Dependabot: Group your updates, slow the cadenc...
Automate all the things: How to use Grafana Cloud's AI to relieve the operational burden
Continuous integration and continuous delivery (CI/CD) have dramatically changed how we ship software. But once code reaches production, the operational work is still surprisingly manual. Engineers continually monitor systems, investigate unexpected behavior, and decide which issues require action. ...
