    CAcert's root certificate is not included in the default trust stores of most major web browsers, which means users often need to manually install the certificate, reducing convenience and potentially trust.

    Compared to commercial CAs, CAcert may offer less robust customer support and troubleshooting services, as it lacks the resources and infrastructure of larger, profit-driven entities.
