I’ve been using Shield for over a year now. I manage about 20 instances of WordPress, plus some staging servers for each. And I now install Shield by default every time I get WP going. Shield is comprehensive in what it helps protect, its settings are easy to understand and configure, its protections are effective, and I’m completely happy with the peace of mind it offers once installed.

The free version is full-featured enough for many of our sites. But to top that off, to upgrade to pro at only $12/year is well worth the price for several of our sites that require an extra level of configuration or custom settings.

I’ve been in touch with their support team for two separate issues/requests. Their team is responsive, helpful, and willing to work through issues through to resolution. Whether the issue be on my end with my server config, or on their end with changes they might need to make to their code. Excellent, friendly, knowledgeable team.

Solid, easy to make recommendation to anyone wanting to further tighten up WordPress security.
