6-Layer Website Monitoring

Website monitoring that actually sees what breaks.

Q: What is 6-layer website monitoring?

Visual Sentinel monitors 6 layers: Uptime (is your site reachable), Performance (Core Web Vitals), SSL (certificate expiry and chain issues), DNS (record changes and hijacking), Visual (pixel-level screenshot comparison), and Content (text and markup change tracking). Most monitoring tools only check uptime.

Q: How is Visual Sentinel different from Pingdom or UptimeRobot?

Pingdom and UptimeRobot primarily check if your server responds. Visual Sentinel adds visual regression detection, SSL certificate monitoring, DNS change tracking, and Core Web Vitals — catching problems that return HTTP 200 OK but show a broken page to visitors.

Q: Do I need to install anything?

No. Visual Sentinel monitors externally — just paste your URL. No code changes, no agents, no browser extensions required. Setup takes under 60 seconds.

Q: How fast are the alerts?

Alerts are delivered within minutes of detection via your choice of Email, Slack, Discord, WhatsApp, Telegram, or custom webhooks. Each alert includes screenshots and diagnostic data.

Q: Is there a free plan?

Yes. Try any plan free for 7 days with no credit card, or start a 14-day trial with card. Plans start at $6/month (Solo) with all 6 monitoring layers.

Q: What notification channels are supported?

Visual Sentinel supports Email, Slack, Discord, WhatsApp, Telegram, PagerDuty, OpsGenie, Microsoft Teams, Prometheus, and custom webhooks — 10 channels total.

Uptime checks say “all clear” while your visitors see a broken page. Visual Sentinel monitors 6 layers—uptime, SSL, DNS, performance, visual, and content.
