SaaS Monitoring
Website Monitoring Built for SaaS Teams
Your SLA is a promise. Every minute of undetected downtime erodes the trust your customers placed in your product. Sentinel gives SaaS teams 30-second monitoring from four global regions, structured incident management, and branded status pages so you can meet your uptime commitments and prove it with data.
Full-Stack Visibility
What to monitor on a SaaS application
A modern SaaS product is a web of endpoints, APIs, auth flows, and integrations. A failure in any layer degrades the experience for every user. Here is what Sentinel watches for you.
Application endpoints
Monitor your core app URLs with 30-second checks from four global regions. Catch full outages and partial degradations before users file support tickets.
API health
Validate response codes, latency, and payload content on your public and internal APIs. A slow API cascades into a slow product experience.
Login and authentication flows
Verify that login pages, OAuth callbacks, and SSO endpoints stay available. Locked-out users churn faster than any other failure mode.
SSL certificates
Track certificate expiry and chain validity across every domain your product uses. An expired certificate breaks trust and blocks access in modern browsers.
DNS for custom domains
Monitor DNS records for white-label or custom domain features. Detect misconfigurations or unauthorized changes before they impact your customers.
Webhook endpoints
Confirm your inbound and outbound webhook URLs respond correctly. Silent webhook failures break integrations without obvious user-facing errors.
Reliability as a Feature
Why SaaS teams choose Sentinel
SLA Compliance
Track uptime against 99.9%, 99.95%, or 99.99% SLA targets with detailed historical reports. Know exactly where you stand at any point in your billing cycle, and export the data your customers need to verify compliance.
Public Status Pages
Give your customers a branded, real-time status page they can bookmark and check during incidents. Reduce support ticket volume, build transparency, and show your commitment to reliability without sending a single email.
Incident Workflow
Follow a structured detect-acknowledge-resolve-postmortem workflow for every incident. Assign team members, track timelines, post public updates, and generate postmortem reports that help you prevent the same issue twice.
Multi-Region Verification
Sentinel checks from four continents before confirming an outage, eliminating false positives caused by regional network issues. When your SaaS serves a global audience, single-region monitoring leaves blind spots.
FAQ
SaaS monitoring questions, answered
Can Sentinel monitor my API and health-check endpoints?
Yes. Sentinel can monitor your application and API endpoints, including health-check URLs, with 30-second checks from four global regions.
Can it verify the actual content of an API response, not just the status code?
Yes. JSON response assertions let Sentinel inspect the body of an API response and confirm specific fields or values are correct, so a health endpoint that returns 200 but reports a degraded state still raises an alert.
How does Sentinel avoid false alarms from a single bad region?
Every check runs from four global regions and an outage is confirmed by consensus before you're alerted, which filters out false positives caused by an isolated regional network issue.
Can Sentinel monitor SSL and DNS for our custom domains?
Yes. Sentinel checks SSL certificate validity and expiration as well as DNS records and domain expiration, which is useful for white-label and custom domain features.
How will my on-call team be alerted to an incident?
Alerts can be sent via email, SMS, Slack, Discord, and webhooks, so you can route incidents into the on-call tools and channels your team already uses.
Is there a free trial for SaaS teams?
Yes. Paid plans include a 14-day free trial and there's also a free plan to get started. You can cancel anytime.
