Website monitoring made simple and better

Website monitoring, the continuous process of testing a website from global locations, can help you measure your site's performance and minimize downtime. However, this does not give you a complete picture.

With Site24x7, besides uptime status, you can also monitor the performance of services like DNS, FTP, and SMTP, check API health, detect unsafe URLs, communicate incidents when outages strike, and more to deliver a top-notch end-user experience.

Monitor website uptime and page speed

Global monitoring network: 110+ locations

Don't wait for users to report that your website is down. Continuously check the uptime of your IPv4/IPv6-enabled websites from relevant customer locations every one minute to ensure availability for your globally distributed users. Configure intelligent thresholds and get alerted via multiple notification channels in the event of an outage. We also verify downtime from alternative locations to prevent false positives.

Analyze webpage speed using a real browser

Slow loading pages don't just frustrate users—they can also lead to page abandonment. Render your website using a real browser, and record load time for each static resource like documents, images, JavaScript, videos, and other files to identify assets that may be slowing your page down.

Secure your website and users

Ensure service reliability and never lose the trust of your users.

Website Defacement

Immediately detect unauthorized changes to the integrity of your website. Enable an automatic baseline to uncover everything from iframe/script injections to content modification.

SSL/TLS Certificate

Easily stay up to date with SSL/TLS certificate expiration. Setting up a check not only notifies you before they expire, but also monitors for certificate revocations, untrusted CAs, and SHA-1 fingerprint tampering.

Real-time blocklist check

Periodically run queries against popular blocklists like Surbl, SORBS, Invaluement, UCEPROTECT, and more to detect domains and IP addresses marked as spam.

Brand Reputation

Keep your business and users safe. Identify infected or malicious URLs and remove them from your site by running checks against Google's list of unsafe web resources.

Domain Expiry

When a domain expires, all the services attached to it will cease to work. Set up a simple check, renew early, retain ownership, and prevent any unintended service disruption.

Improve digital end user experience

Combine synthetic and real user data to achieve a high level of performance.

Synthetic Monitoring

  • Proactively test the response time and functionality of critical transactions or endpoints 24x7 from worldwide locations.
  • Simulate navigation paths—common actions like sign up or a complex user journey from login to the payment gateway—on a real browser to identify and resolve potential issues before they affect your customers.
  • Point and click the elements that you want the test to interact with using our recorder tool, or upload the existing Selenium IDE test cases to get started.

Real User Monitoring

  • Measure the real-world experience for your website and single-page applications.
  • Capture high resolution times for page loads. Analyze statistics by dimensions like geography, browser, or device to identify whether you are delivering a consistent experience.
  • Monitor performance data for interactions that lead to a view change, along with all the AJAX requests for single-page applications (SPAs). Upload source maps and troubleshoot JS errors using stack trace details.

Eliminate blind spots with complete visibility

Gain comprehensive visibility across all the resources involved in delivering your service.


Easily track the health of your app's REST API and SOAP endpoints. Add JSONPath or XPath assertions to ensure your API responses are returning the right data.


Monitor WebSocket endpoints to ensure real-time apps like live chat software and social media feeds on your website are working as expected.

Domain Name Server

Monitor resolution time, identify Domain Name Server (DNS) propagation issues, and verify the correctness of your domain's DNS records by performing lookups from multiple locations around the world.

Mail Delivery

Simulate an email flow end-to-end by sending and receiving test emails using your Simple Mail Transfer Protocol (SMTP), POP, and IMAP servers to measure latency and identify email deliverability issues.

File Transfer Protocol

Check upload and download performance for SSL/TLS-enabled FTP servers to make sure external file downloads are happening without any glitches.

TCP/IP Ports

Track the availability for any service that is listening on well-known ports (SMTP, POP3, IMAP, or FTP) and registered ports over the Transmission Control Protocol (TCP).

Internal Network

Complement our global monitoring network by installing a lightweight software component in your internal network to monitor resources behind the firewall.

Monitor from 3G/4G networks

Understand how your site performs when accessed on low bandwidth connections offered by your mobile network carrier.

Efficiently Communicate Incidents

Hosted status pages

High traffic days, third-party service outages, or service interruption to a hosting provider can render your website inaccessible. During times like these, proactively sending out updates regarding the status of your systems and what you are doing towards a fix can keep your customers happy. With our hosted status pages product, you can transparently communicate the real-time status of your web service and prevent unplanned downtime from affecting your bottom line
