SentryPage
Monitor Website Defacement Intelligently
Let SentryPage be your digital watchdog.
A website defacement monitoring service. It screen-captures registered web pages at intervals as short as 5 minutes, compares each capture against the previous one to find changes, scans those changes through two detection engines for anomalies, and emails an alert if the change looks like a defacement. The stated goal is minimising false alerts by evaluating each suspicious change rather than flagging every difference.
SentryPage StackBuilt for control, shipped fast.
Catches injected code, not just visible text.
Flags images, scripts and redirects that point to unrecognised external domains in your page.
You find out before the public does.
Checks your origin behind the cache, so you see defacement or downtime before the public does.

Enterprise questions, answered.
SentryPage is a website defacement monitoring tool from Xtremax. It watches your website continuously and alerts you when an unauthorised change appears, backed by 24x7 business support.
Defacement is when an attacker changes the appearance or content of your website without permission, for example by replacing pages with hacker signatures, profanities or injected content. It damages your corporate image and public trust, so catching it quickly matters.
Its Attack Signature Engine™ compares your pages against a database of thousands of analysed defacement patterns, including hacker signatures and profanities. The database is updated regularly, so detection keeps improving. AI-based computer vision that recognises defaced pages from screenshots is an upcoming feature.
Yes. Its External Resource Engine™ spots unidentified external domains attached to your website, so it catches a hacker adding a foreign image or script, or redirecting visitors to another address.
The signature engine understands defacement content in multiple languages, including English, Russian, Arabic, Chinese, Indonesian, Italian, Portuguese and Turkish, and coverage keeps expanding.
The engine evaluates each suspicious change intelligently rather than flagging every difference. This keeps alerts accurate, so you are notified only when you actually need to act.
Yes. By whitelisting SentryPage's request header or IP, its checks bypass your infrastructure's cache and see the live site even while visitors still see a cached copy. This also helps during downtime or application errors, so you can restore your website before anyone notices.
Yes. Every small change is recorded, so you can track how your website has evolved over time and spot even the slightest modification.
