Our website is being constantly attacked by the bots. We tried mod_evasive and mode_security but those modules slowed our server considerably. Can anybody please suggest more solutions. Thanks in advance.

This question appears to be off-topic. The users who voted to close gave this specific reason:
- "Requests for product, service, or learning material recommendations are off-topic because they attract low quality, opinionated and spam answers, and the answers become obsolete quickly. Instead, describe the business problem you are working on, the research you have done, and the steps taken so far to solve it." – EEAA, yoonix, mdpc, masegaloeh
There is almost nothing you can do on your site to defend from DDoS. Essentially when malicious traffic reaches your site it is already too late to do anything. Your best chance to defend yourself is by using third party provider. There are several of them offering different features for different budgets but you could start with Incapsula or Cloudflare.
