In their own words
ThousandEyes DNS Monitoring
ThousandEyes DNS Monitoring tracks DNS servers, resolvers, and records across customer and provider networks to identify availability, performance, and security issues. It covers on-premises, hosted, and third-party DNS servers, checking availability, resolution speed, and record mappings. Tests can discover DNS infrastructure, trace routing and paths, measure resolver responsiveness, and check record accuracy. The service can trace a record's DNS hierarchy from top-level servers to the authoritative server, and verify the DNSSEC keychain from the bottom up. Users can configure and export alerts for availability, record mappings, DNSSEC, and record changes, including changes that may indicate cache poisoning. Alert destinations include email, SMS, webhooks, PagerDuty, Slack, ServiceNow, AppDynamics, Splunk, Webex, and Microsoft Teams. The Network & App Synthetics plan is an annual subscription priced according to visibility needs and test units; pricing is on request. A 15-day trial includes Cloud Agents in 20+ global locations and Enterprise Agents for customer infrastructure and cloud VPCs.
Visual Sentinel
Visual Sentinel monitors websites and servers, including page changes that ordinary uptime checks may miss. Its monitoring covers uptime, screenshot-based visual comparison, SSL, DNS, performance, content, APIs, endpoints, and servers. For visual checks, it captures a page in a browser and compares the screenshot with a prior baseline. Users can exclude changing page elements with CSS selectors and set the amount of change needed to flag a capture. Failed uptime checks are repeated; a site is marked down only if it fails from all selected regions. Alerts can go to email, Slack, Discord, WhatsApp, Telegram, Microsoft Teams, PagerDuty, OpsGenie, webhooks, Prometheus, and browser push. The REST API manages monitors, incidents, status pages, maintenance windows, reports, and notification channels; API access is listed for Business and Agency. The Free plan costs nothing and includes three monitors, 10-minute checks, and one status page. Solo costs $6 a month. Visual Sentinel is built and operated by Acefina LLC and is intended for small teams, agencies, and site owners.
