Hospedando o plugin ALTCHA Spam Protection em uma empresa de hospedagem confiável

A MCO2, além de configurar e instalar o WordPress na versão mais nova para seus clientes, fornece o plugin WP SafePress, um mecanismo exclusivo que protege e melhora seu site simultaneamente.

Por que a Hospedagem WordPress funciona melhor na MCO2?

A Hospedagem WordPress funciona melhor pois a MCO2 possui servidores otimizados para WordPress. A instalação de WordPress é diferente de uma instalação trivial, pois habilita imediatamente recursos como otimização automática de imagens, proteção da página de login, bloqueio de atividades suspeitas diretamente no firewall, cache avançado e HTTPS ativado por padrão. São plugins que potencializam seu WordPress para a máxima segurança e o máximo desempenho.
