Insights

Acquisition History Postini is a historically acquired security and email filtering player now integrated into Google, indicating potential alignment with Google’s security stack and opportunities to upsell enhanced email security, data loss prevention, and cloud security integrations to Google Workspace customers.

Midmarket Focus With a small team size (11-50 employees) and revenue in the mid-tens of millions, Postini targets mid-sized enterprises; sales opportunities exist in expanding security services and managed IT offerings to similar midmarket organizations.

Email Security Footprint As one of the early email filtering solutions historically competing with Mimecast and Proofpoint, there is a strong foothold in email security; cross-sell or upsell advanced threat protection, archiving, and compliant email workflows to current and former Postini/Google customers.

Growth Signals Recent three-way context shows robust interest in cloud security and AI-driven security (given peers in the sector), presenting opportunities to position Postini-related offerings alongside growing demand for threat intelligence, SOC services, and security analytics.

Partnership Potential Credit history and funding indicate vested interest in scalable security solutions; explore partnerships with MSPs and system integrators serving midmarket clients to expand reach for Postini-aligned email and cloud security services.
