Viglar continuously monitors your website, domain and security and tells you when something changes. Uptime is only the beginning.
Records, mail security (SPF, DKIM, DMARC), and anything that changes without you knowing.
We watch for signs your domain is being transferred or taken over and alert you before it's too late.
Whether your IP has landed on a spam or abuse blocklist.
Security headers that help protect your site from common web attacks.
Domain expiry and registrar changes - so you can act before a forgotten renewal becomes a problem.
Monitors domain registration data and detects changes to registrar and registration details.
Open ports that shouldn't be - databases, admin panels, forgotten services.
Certificate expiry and validity, before your visitors see a warning.
Is it actually up, and how fast does it respond.
Unexpected changes to your site that may deserve investigation.
Get notified wherever your team already lives - Telegram, Discord, Slack, or your own system via webhook.
Every issue we find comes with a plain-language explanation and the exact steps (or DNS record) to fix it - no need to google what DMARC means.
When it expires, browsers will show visitors a warning page instead of your site.
Schedule maintenance windows to suppress notifications during planned downtime while monitoring and event recording continue.
See what changed, when it happened, and how the issue progressed - from detection to recovery. Your domain's events, all in one timeline.
