Harness October 2026 Updates: 150+ Features, Cosmos, FedRAMP 20x This Month's Biggest Ships: The shipping velocity at Harness skyrocketed. Harness shipped 150+ features in October, one about every 5 hours across 31 days! October's list covers both ends: code creation and software delivery. The biggest ship is Cosmos, a new agent that takes engineering work from ticket to pull request. The rest carries that pull request to production and keeps it safe.

Cross-source API correlation connects runtime findings to their code, documentation, and fixes for improved defense against machine-speed attacks. It's late on a Thursday, and a runtime alert fires on POST /api/v2/payments in production. The finding is clear. What happens next is not. In fact, it creates a host of questions to be answered: Every AppSec team knows this hunt. And every day spent hunting for the right repo and owner is a day the attacker can still exploit a vulnerability.

It's no secret that getting started with observability can be much harder than it should be. That's why, at ObservabilityCon 2025, we introduced Instrumentation Hub: a guided, scalable way to roll out observability coverage while still keeping you in control. Today, we’re excited to announce that Instrumentation Hub is now Generally Available in Grafana Cloud.

Most network diagrams we come across land in one of two piles: the one drawn for an audit years ago and never opened since, and the one so crowded that finding the firewall takes squinting. The network diagram examples below sit between those piles, 8 diagrams IT teams actually use, sorted into physical, logical, and cloud or WAN. For the full build process behind one map, see our guide to the network topology diagram.

Think about Outlook, Salesforce or the shared drive your staff open each morning, and at least one of them probably runs in AWS, Azure or Google Cloud. That puts a good share of your traffic on a cloud network nobody on your team has ever seen. You still own a lot of that path (the VPN link, the route tables, the security groups), and it breaks in ways an office network doesn't.

When a mobile application takes too long to launch or becomes unresponsive, it can be difficult to find the cause. Datadog Real User Monitoring (RUM) helps developers detect these issues and understand which users are affected. But knowing that an application is slow doesn’t tell you which part of its code is responsible. Engineers often need to reproduce the problem locally, piecing together performance metrics and code execution information from separate tools.

Prompts are an important part of LLM application behavior, but teams often manage them alongside application code or across separate notebooks and configuration files. This can make prompt changes dependent on application releases and make it difficult to understand which version is running in each environment. When a change affects application quality, latency, or cost, teams also need a way to connect that behavior back to the prompt version that produced it.
