Website monitoring that sees what your uptime tool misses.
Your site returned 200 OK, but a WordPress plugin broke the layout, an SSL cert expired silently, and a DNS change went unnoticed. Visual Sentinel monitors 6 layers so you catch what others miss.

Alert Time
6 things your current monitor can't see
Most tools only ping your server. We monitor the actual experience your visitors get.
Uptime Monitoring
Your site went down at 3 AM. Without monitoring, you find out from an angry tweet at 9 AM. We alert you in 60 seconds.
SSL Certificate Tracking
Auto-renewal failed silently. Chrome blocks your entire site. We alert you 30 days before expiry so this never happens.
Visual Change Detection
A plugin update broke your homepage layout. HTTP says 200 OK. We screenshot your site and catch the visual regression instantly.
Performance Tracking
Page load jumped from 1.2s to 4.8s after a deploy. We track TTFB, Core Web Vitals, and response time trends over time.
DNS Monitoring
Someone changed your DNS records. Domain hijacked, or just a migration mistake? We detect it and alert you before users are affected.
Content Monitoring
Your site was defaced, prices were changed, or a CMS update wiped content. We track page content and alert on any unauthorized changes.
Your uptime monitor says everything is fine. It's not.
A broken checkout page, an expired SSL cert, a CSS regression after a deploy, these all return HTTP 200 OK. Your uptime tool sees nothing. Visual Sentinel sees everything.

Monitoring that sees the whole picture
Connect your Google, Cloudflare, and server agents. Visual Sentinel correlates uptime with traffic, infrastructure, and root cause so alerts tell you why, not just what.
Google Analytics & Search Console
Connect once. See GA4 sessions, users, and GSC impressions, clicks, and top queries right on each monitor. Automatic per-site linking, 7-day backfill on connect, daily sync. Bundled into your weekly digest.
- Per-monitor traffic
- Top queries + pages
- Email digest included
Cloudflare one-click import
Paste a scoped CF API token and import every proxied domain as a monitor. We handle the proxy-bypass automatically so you check the origin, not the edge cache. No more silent backend failures.
- Zone-scoped tokens only
- Origin-IP resolution
- Zero-config bypass
Server ↔ Site correlation
Install the server agent, and Visual Sentinel auto-links monitors to the host via DNS + IP matching. When a site goes down, the alert includes CPU, RAM, and disk stats so you know instantly whether it's a code issue or an infra issue.
- Auto-link via DNS/IP
- Grouped server-outage incidents
- Bulk linking in UI
Smart Diagnostics
Notifications explain the root cause, not just the symptom. Down alerts surface linked-server health, recent deploys, and stress thresholds. Incident detail shows a dual-axis timeline overlaying server metrics with response time.
- Root-cause in the alert
- Dual-axis timeline
- Server context in emails
Built for teams that ship fast and break things
Whether you run WordPress sites, SaaS apps, or manage client portfolios, Visual Sentinel catches what other monitors miss.
WordPress & CMS
Plugin updates break layouts. Theme changes shift content. SSL certs expire on shared hosting. We catch it all with visual + SSL + content monitoring.
E-Commerce
A broken checkout page costs sales every minute. Visual monitoring detects missing product images, broken carts, and payment form issues that return 200 OK.
SaaS & Apps
Deploy with confidence. Visual regression detection catches CSS breaks, missing components, and layout shifts before your users file support tickets.
Agencies
Monitor all client websites from one dashboard. Whitelabel status pages, custom SMTP, and branded reports. Up to 300 monitors on the Agency plan.
