Zscaler for engineering heavy organisations

Hi all,

After some advice please! The org I work for is a very Engineering heavy workforce and Zscaler is a constant disruption to their development work (either due to SSL inspection or slow performance).

For now, we have bypassed SSL inspection completely for Engineers which of course this is a massive gap but the best approach we could take

Is there any similar orgs here and if so, how has Zscaler worked for you around this issue?

EDIT: Thanks for all your advice, it was really helpful and got some good ideas here I'll take away and look into. Now time for the battle vs engineers... wish me luck!
