Would like to know all possible way to make my WordPress site secure from hackers.
Are there any experts who can share their tips here?

One of my co-workers shared these ones:

• Create WordPress Sites on FLATsite
  
• Use TLS or SSL Certificates
  
• Utilize DDOS Protection
  
• Implement a Website Back-up
  

Have you tried FLATsite static wordpress site generator? Is it really good solution?
So, could you share your view points on securing wordpress site from hackers?

Thanks.

Cool option - Thumbs up to FLATsite. It allows you to deploy unlimited websites and manage all of them from a single, user-friendly dashboard. Definitely some of the best Customer Support available. Support can be reached through MSN for immediate assistance, and through tickets/email which they respond to in a matter of minutes.
