Prompt Injection Handling Guidelines

This is cool. Thank you. I also need a suggestion from you one one thing, my bot is for eldelry friendly assistance , should I integrate Lukera https://www.lakera.ai/ to avoid prompt injections and other security issues? My worry is bot will become very slow ,if I inetgrate with various frameowrks. Since my bot is voice bot ,it is already slow because of STT and TTS. You advice is highly appreciated. Thank you in advance.
