Why monitor your website?

Your website should always be available and performing at it's best. If it’s not, you risk losing visitors and customers.

Some issues are easy to notice, like a full outage—but others, like slowdowns, go unnoticed until they start costing you revenue. A single change can impact performance without you realizing it.

Vigilant monitors your site 24/7, infrastructure changes, performance issues and broken links, so you can fix them before they affect your customers.

When your website matters, stay vigilant to keep it running smoothly.
