Security is a primary surface in Sencho. The **Security** page in the top navigation brings the
capabilities that power [vulnerability scanning](/features/vulnerability-scanning) into one command
center, so you can answer "what should I look at first?" without hunting through other pages. It is
scoped to the active node: the findings and scanner status you see reflect whichever node is selected.

The page is organized into tabs.

## Overview

The overview opens with a status masthead that reads your **action posture** at a glance, the answer
to "what can and should I do right now?":

- **Action needed**: something concrete to act on, such as a fixable Critical or High finding, a
  detected secret, a dangerous Compose setting, or a known-exploited (CISA KEV) CVE.
- **Monitoring**: Critical or High findings exist, but none are currently actionable (no fix
  available, or already triaged).
- **Secure**: nothing actionable right now. This is never a claim that no vulnerabilities exist.
- **Unknown**: the scanner is not installed, or no scan has completed yet.

Raw Critical and High counts stay visible next to the posture as **scanner detections**, not as the
posture itself: a vulnerable component being present is not the same as a reachable, exploitable risk.
The masthead carries a standing note to that effect, and posture weighs fix availability, exploit
intelligence, and triage decisions rather than raw severity alone.

Below the masthead, a **Review queue** card leads the overview when actions or review items exist.
When the posture is Action needed the card is titled **Why Action needed** and lists each concrete
action with a count and a tab-shortcut button: fixable findings, known-exploited CVEs, detected
secrets, unacknowledged Compose risks, and publicly exposed affected images. When only monitoring
items remain (exposed images with no fix or known exploit, findings awaiting triage, stale or failed
scans) the card is titled **Review queue** and lists them without the red masthead, so the operator
can see what to keep an eye on without a permanent alarm.

The charts then lead with prioritization rather than raw severity: a **risk trend** for context,
an **action posture** breakdown (fixable, known-exploited, needs-review, accepted, not-affected), a
**top exploit-risk** list ranking actionable findings by known-exploited status then EPSS, and a
**severity-by-exploitability** quadrant that separates high-severity-but-unlikely findings from the
ones to act on first. The exploit-risk charts populate once exploit intelligence is enabled and images
are scanned. A signal rail summarizes the supporting numbers (scanned images, fixable findings,
secrets, Compose misconfigurations, stale scans, failed scans), and a status strip shows scanner health
and the active node's deploy enforcement posture.

If a node does not report an overview (for example an older remote node), the page falls back to a
clear "overview unavailable" state and the other tabs keep working.

## Images

Image findings list every scanned image on the active node with its highest severity. Selecting an
image opens the full scan report, where you can review vulnerabilities, triage a CVE, and export an
SBOM. Each finding carries evidence tags so you can tell scary from exploitable at a glance:
known-exploited (KEV), EPSS exploitation probability, the CVSS score, and vendor "will not fix"
status, alongside whether a fix is available.

## Compose risks

Compose risks surface the security misconfigurations Trivy finds in your stack definitions rather than
image CVEs: privileged containers, Docker socket mounts, host networking, broad host bind mounts, public
database ports, and containers running as root. Each entry opens its scan report with the specific
findings and how to fix them. This is a security audit of the Compose file; for deploy-readiness checks
(port conflicts, missing bind paths, unset variables, no healthcheck), use
[Compose Doctor](/features/compose-doctor) from the stack page instead.

## Secrets

The secrets tab lists images where Trivy detected exposed credentials or keys, and opens straight to
the secret findings for a scan.

## Policies

The Policies tab manages deploy-enforcement scan policies: severity thresholds that block or warn on a
deploy, scoped by stack pattern. See
[scan policies](/features/vulnerability-scanning#scan-policies) for the full configuration.

## Suppressions

CVE suppressions and misconfiguration acknowledgements are managed here, the same controls available
in Settings. These are governed by the local instance, so this tab is shown when you are on the local
node; switch to the local node to manage them.

Suppressing a CVE records a **triage decision**: accepted risk, not affected, false positive, fixed,
ignored, or needs review, with an optional OpenVEX justification. Decided findings stop driving the
action posture; a "needs review" decision stays counted but keeps the finding actionable. You can
export the fleet's triage decisions as an OpenVEX document for use with other tooling.

## History

The History tab lists completed scans for the active node in an inline table. Prefer digest identity when a digest is stored (short digest as the primary label, image reference as the subtitle); config and other scans without a digest show the image reference. Search matches image references or digests. Select two scans to compare. The **Scan history** button in the [Resources Hub](/features/resources) is a shortcut to the same place. For how tags and digests relate, see [Tags vs digests](/features/vulnerability-scanning#tags-vs-digests).

## Scanner setup

Scanner setup manages the Trivy binary for the active node: install the managed binary, update it when
a new release is available, and toggle automatic updates. Trivy is installed independently on each
node. See [Installing Trivy](/operations/trivy-setup) for the full setup options.

It also toggles **exploit intelligence**: a daily background fetch of the CISA KEV catalog and FIRST
EPSS scores that powers the known-exploited and EPSS evidence tags. It degrades gracefully when
offline and can be turned off for air-gapped or firewalled hosts.

## What stays where

Resources keeps its per-image severity badges and scan actions, so you can still scan and inspect an
image from your inventory. Security is the place to review the whole picture; the deeper scanning
workflow (on-demand scans, scheduled fleet scans, scan policies, SBOM and SARIF export) is documented
under [Vulnerability scanning](/features/vulnerability-scanning).
