See external infrastructure issues before your customers do.
Continuously monitor internet-facing services, certificates, DNS, availability, and exposure changes - without agents or internal credentials.
Built for teams responsible for internet-facing systems.
Start with public evidence, then turn important endpoints into continuous monitoring.
MSPs & Managed Service Providers
Review customer-facing exposure and monitor critical endpoints from one operational view.
Telcos & Cloud Providers
Track public services, HTTPS endpoints, certificates, and infrastructure changes.
Hosting Operators
Find customer-facing issues earlier and keep evidence ready for incident response.
Infrastructure Teams
Maintain a current view of externally visible services without replacing internal observability.
Discover exposure. Monitor availability. Detect change.
One workflow for the evidence operators need before, during, and after an incident.
Build a public view of reachable hosts, DNS records, HTTPS services, and certificate evidence.
Continuously check critical websites, APIs, endpoints, and certificate validity from outside your network.
See when DNS, certificates, or externally visible services change so teams can investigate with context.
From free evidence to continuous monitoring.
No agent or internal network access is required for the public scan.
Know What Your Infrastructure Exposes
Sentryx examines the public-facing security signals attackers can observe during reconnaissance.
Security Changes When Your Infrastructure Changes
Certificates expire. DNS records change. Services appear. Ports open. Websites fail. Sentryx continuously monitors these signals so your team does not have to repeatedly check them manually.
Your External Security in One View
Turn scattered external security signals into a single view of your attack surface, monitoring health, and issues requiring attention.
Need monitoring beyond a one-time report?
Tell us about your environment. Our business team will recommend a practical scope based on assets, locations, and operational needs—without forcing a public plan choice.
Security Intelligence
Questions operators ask before starting.
Does Sentryx need internal access?
No. External monitoring uses public signals and does not require VPN access, cloud administrator credentials, or an installed agent.
What can I monitor?
Websites, APIs, DNS, TLS certificates, domains, supported services, and externally visible changes.
Does this replace penetration testing?
No. Sentryx provides broad continuous visibility. Authorized penetration testing validates specific attack paths at a point in time.
What data does the free scan retain?
The scan processes public response evidence and stores report metadata needed to operate and protect the service. It does not retain response bodies or collect credentials.
Can a proxy hide the origin?
Yes. CDNs and reverse proxies can hide origin infrastructure, so findings describe what Sentryx can observe publicly—not every internal asset.
Is Sentryx currently certified?
Sentryx is not currently SOC 2 or ISO 27001 certified. Security controls and data handling are described without implying certification.
Start with evidence from the public internet.
Run a bounded external scan, review the full report, then decide whether continuous monitoring fits your environment.
