You’ve seen it happen before. By the time you notice, the damage is already done. Lost revenue. Frustrated users. Awkward client conversations.
A customer tells you your site is down
The worst way to find out. Your customers shouldn’t be your monitoring system.
An SSL certificate expires without warning
Browser security warnings kill conversions instantly. Renewals that slip through cost real revenue.
A domain renewal slips through the cracks
Domain loss is catastrophic. A missed renewal date can take a business offline in hours.
DNS changes break things quietly
Misconfigurations and unauthorised changes break services silently. You need to know first.
Get complete visibility across your infrastructure without setting up complex tools or dashboards.
HTTP Check
Monitor your web endpoints with precision. Sentinel performs ongoing HTTP checks to ensure your services are up, responding correctly, and performing within expected thresholds. Get alerted instantly when endpoints fail or degrade.
SSL check
Track SSL certificate status across your domains. Sentinel proactively monitors for expiry, misconfigurations, and chain issues to ensure secure and uninterrupted connections, giving you ample time to renew before problems arise.
DNS Audit
Get full visibility into your DNS configuration. Sentinel audits DNS records to detect inconsistencies, propagation delays and misconfigurations – helping you avoid outages and ensure reliable domain resolution.
Domain
Track critical changes to your domain status. Sentinel monitors WHOIS data and domain records for updates like registrar changes, expiry risks, or ownership modifications, keeping you informed and in control of your digital assets.
Notifications
Get notified where it matters most. Using the integrations connected to your team, Sentinel delivers real-time alerts about downtime, performance issues, and system events, ensuring the right people are informed at the right time.
Team
Easily manage users, roles, and permissions. Sentinel enables team-based access control so you can assign responsibilities, delegate tasks, and maintain secure collaboration across your monitoring infrastructure.
Workflows
Design no-code automations across your infrastructure. Sentinel Workflows enable custom triggers, conditions, and actions to streamline operations, eliminate repetitive tasks, and respond to events in real time.
Integrations
Connect Sentinel with your existing tools. Whether it’s Slack, Microsoft Teams, or custom webhooks, our integrations ensure alerts and updates flow directly into your incident response and monitoring stack.
Sentinel is designed for people who need monitoring to just work – without dedicated infrastructure teams or complex tooling.
