Halcyon plugs into your repos, container registry and runtime to surface exploitable risk — not noise. Built for security engineers and the developers they support.
Trace every CVE from your lockfile through call graphs to the running process. Ignore what isn't loaded; prioritise what executes on the request path.
Image layers, Dockerfiles, Terraform, Helm charts. One pass per commit, results land in PRs as comments engineers actually read.
eBPF agents close the loop: which library versions actually loaded, which endpoints reached the network, which findings can stop being theoretical.
Express your tolerance in Rego or YAML — block PRs, open Linear tickets, page on-call. Every gate lives next to the code it guards.
GitHub / GitLab app + registry creds. Two minutes.
→Inventory deps, images, infra. Baseline severity.
→Reachability + exploit intel collapses noise ~10×.
→Auto-PRs, owner routing, SLA-aware nags.
Halcyon onboardings are run by the same engineers who ship the platform. Tell us about your stack and we'll show you what an assessment of it would surface — usually within 48 hours.
