Frequently Asked Questions
What is included in the CISO Email List?
The CISO Email List contains 85,000+ human-verified chief information security officers, VPs, and directors of information security across enterprise, mid-market, financial services, healthcare, and public sector organizations in 120+ countries.
How do you keep senior security contacts accurate?
CISO roles turn over frequently. We re-verify every 30 days through four gates — domain validation, live inbox verification, a manual researcher audit, and an opt-out scrub — so departures never reach your campaigns.
Can I filter CISOs by company size or security stack?
Yes. Segment by headcount, revenue band, vertical, or detected tooling such as CrowdStrike, SentinelOne, Splunk, and Palo Alto to align messaging with each environment.
Is outreach to CISOs compliant with privacy law?
Yes. Every record comes from public professional sources and opt-in channels, is suppressed against do-not-contact registers, and remains fully GDPR and CCPA compliant. DPAs available on request.
