What security features are non-negotiable for a new crypto exchange?

At minimum: 2FA, cold wallet storage, multi-signature wallets, end-to-end encryption, DDoS protection, and KYC/AML integration. A lot of exchanges skip proper security audits and penetration testing before launch, which is how hacks happen.
I'd recommend not treating security as an add-on — it needs to be baked into the architecture from day one. Some cryptocurrency exchange development services build this in as a core part of the process rather than bolting it on after launch, which is the approach I'd look for.
