FAQ - Common questions
Answers to frequently asked questions about security plugins.
Do I need a security plugin if I have managed hosting?
Managed WordPress hosts provide server-level security, but a plugin adds application-level protection like login security, file monitoring, and malware scanning that hosting doesn't cover.
Will security plugins slow down my site?
Server-side WAFs (Wordfence) can add some overhead. Cloud-based solutions (Sucuri, Cloudflare) actually improve performance. We recommend balancing security needs with performance testing.
Should I use multiple security plugins?
No, never use multiple security plugins together. They conflict with each other and can cause issues. Choose one comprehensive solution.
