Proofpoint list questions, answered
How many companies use Proofpoint?
Data InfoMetrix tracks 29,818 companies using Proofpoint, with 200,894 verified contacts at those accounts as of October 2026. Counts are estimates from our database and market research, so ask us for a live count for your exact criteria.
Who buys and manages Proofpoint inside a company?
Proofpoint is usually owned by Email Security, Human-Centric Cyber Defense & Threat Intelligence Leadership. Decision-makers include Chief Information Security Officer (CISO), Director of Email Security and VP Information Security; Lead Messaging Security Architect and Exchange / M365 Email Administrator shape the choice, and Email Security Analyst and SOC Incident Responder use it day to day. Our Proofpoint list can include any of these roles.
Which Proofpoint products or editions can I target?
You can target accounts by the Proofpoint products they run, including Proofpoint Email Protection (PPS Enterprise), Proofpoint Targeted Attack Protection (TAP), Proofpoint Threat Response Auto-Pull (TRAP), Proofpoint Enterprise DLP & Insider Threat Management and Proofpoint Security Awareness Training (PSAT). Tell us which edition or module matters and we filter the list to those accounts.
What does Proofpoint integrate with?
Proofpoint is most often connected to Microsoft 365, Splunk, Okta, CrowdStrike and ServiceNow, so users of those tools overlap heavily with Proofpoint accounts. We can filter any list by this kind of stack overlap.
What are the main alternatives to Proofpoint?
The main alternatives to Proofpoint are Mimecast, Microsoft Defender for Office 365, Abnormal Security and Cisco Secure Email. We also keep verified user lists for Mimecast and Abnormal Security, which is useful for competitive displacement campaigns.
What challenges do Proofpoint customers face?
Common challenges for Proofpoint accounts include SEG (Secure Email Gateway) vs Cloud-Native API Defense Misalignment, Reaching Dedicated Messaging Security Leads, Not General IT Staff and Co-Existing Microsoft 365 Security Overlap. Proofpoint customers use enterprise gateway MX records combined with API intelligence. Pitching lightweight API tools without understanding their complex routing, mail encryption, and compliance rules causes friction. These are good angles for outreach to Proofpoint users.
Can Data InfoMetrix deliver a free sample Proofpoint contact list before ordering?
Yes. Data InfoMetrix delivers a complimentary 10-record sample tailored to your target Proofpoint criteria—including target job titles, company size, and region—delivered within one business day with no obligation.
How does Data InfoMetrix guarantee email deliverability for Proofpoint contacts?
Data InfoMetrix provides a 99% email deliverability guarantee on all Proofpoint datasets. Every contact record undergoes real-time email verification within a 30 to 45-day refresh cycle, backed by a 1:1 hard bounce replacement policy for 30 days after delivery.
Sourcing and compliance. Business contacts come from public company sources, professional directories and opt-in publishing partners, then go through SMTP verification and human review. Lists are for B2B outreach: include an unsubscribe link and honour opt-outs (CAN-SPAM), and have a lawful basis such as legitimate interest when you email people in the EU or UK (GDPR).
