The full Safety Check grades encryption, browser protection, sessions, attack filtering, AI agents, software, third parties, email and reputation, and shows exactly which gaps SENTRA closes.
What you should know.
My site works fine on PHP 7.4. Is that a problem?
Yes. PHP 7.4 stopped receiving security fixes in November 2022, so every flaw found since, including the exploited PHP-CGI flaw CVE-2024-4577, stays open.
Should I hide my version numbers?
Yes. Publishing them tells an attacker exactly which published flaws apply to you, without touching the site.
How does SENTRA help?
SENTRA AI SHIELD blocks the request patterns used against known flaws while you upgrade (virtual patching) and strips version banners.
