Exposure monitoring

See the public systems connected to your domain.

Sentryx provides an outside-in view of public domains, subdomains, DNS, HTTPS, TLS certificates, and exposed services. Review the evidence, identify unknown assets, and turn important endpoints into monitors.

What discovery can reveal

Find assets that are missing from the monitoring plan.

Customer-facing risk often sits outside the documented inventory: a staging host, an old subdomain, a public service, or a certificate that no team actively owns.

Domains and subdomains

Map public hostnames connected to the organization, then separate expected assets from unknown hosts and monitoring candidates.

Public service signals

Review internet-facing service evidence that may point to administration tools, legacy systems, public APIs, or infrastructure that needs an owner.

DNS, hosting, and TLS context

Combine DNS, provider, region, IP, certificate, and TLS evidence so each finding is easier to triage and explain.

From discovery to action

Turn important public assets into monitored endpoints.

A static inventory is useful. It becomes operational when selected assets become uptime, SSL certificate, DNS, TCP, HTTP, or keyword checks with evidence-based alerts.

01Scan a domain

Start with a public domain. The scan is read-only and does not require an agent.

02Review the evidence

Separate expected assets, unknown hosts, service signals, and certificate risks.

03Monitor what matters

Turn important endpoints into checks with the appropriate method and interval.

04Share the context

Give owners and clients the host, timing, IP, provider, and failure evidence they need.
