Choose the right perspective
Match the person's security area to your question, since application security, infrastructure and cloud security, offensive red teaming and agent security involve different threats and tools. Check whether they are still at OpenAI and where they worked before, because that shapes how they compare securing an AI lab with securing other companies.

The list covers 1 company: OpenAI, based on profile data retrieved on October 8, 2026. Being listed here doesn't mean someone has agreed to take calls.
How much does it cost to reach OpenAI security engineers?
You choose the offer, starting at $5 per person. It includes Instant Expert's 20% fee, so an offer that pays the person $100 costs you $125. You're charged only when the person books the call or sends the answer.
What if they don't reply?
You pay nothing. Instant Expert sends follow-up reminders, and if the person hasn't booked or answered within 7 days, the request expires and any hold on your card is released. You can invite several of the 10 people on this list at once and cap your total spend, so you pay only for the ones who accept.
Can an AI agent ask one of these OpenAI security engineers a question?

The person answers in writing or by voice note, and if nobody answers within 7 days, the payment goes back to the wallet automatically. x402 docs
