Port visibility
VectraOps records listening/open ports per system so you can quickly answer a simple but critical question:
“what is reachable on this host right now?”. That gives you immediate context during incidents and makes
hardening work measurable over time.
- Per-host list of listening ports and services (where available).
- Searchable inventory across tenants and host groups.
- Quickly validate intended exposure for servers and endpoints.
Spot drift and unexpected listeners
The biggest risk is often not the well-known ports—it’s the one that appeared silently after a change,
a package install, or a temporary troubleshooting action. With regular snapshots you can identify drift
and follow up before it becomes an audit finding or a real compromise path.
Common examples
- A dev tool starts listening on an admin port.
- A legacy service is re-enabled after an update.
- A “temporary” listener stays open for weeks.
Policy rules: allow, flag or deny
Visibility is great, but standards make it actionable. Port policies let you encode what’s acceptable
per environment. When a host deviates—by role, site, or tenant—you get a clear, explainable signal.
- Define rules for ports that are expected vs. unexpected.
- Flag risky listeners (or “deny list” ports) to reduce attack surface.
- Use policies as input for findings/alerts and operational workflows.
Audit-ready evidence
When audits come around, you want proof—not assumptions. Port snapshots and policy outcomes give you
concrete evidence of what was open, when it changed, and whether it matched your standards.
Reduce attack surface with enforceable standards.
