Open Postern's answer
The primary audience is MSPs and IT service providers (10–100 employees) managing security and vendor risk on behalf of SMB clients (typically 5–100 employees per client). Secondary audiences include SMB IT administrators handling vendor risk in-house, and vCISOs and fractional security consultants who need a tool that scales across multiple client engagements without per-seat enterprise pricing.
Open Postern's answer
Open Postern is vendor risk monitoring built natively for MSPs and IT agencies serving SMB clients, with a proper Agencies → Clients → Vendors model and role-based team access from day one. It combines CVE tracking, CISA Known Exploited Vulnerabilities exposure, SSL/TLS health, DNS posture, and AI-curated breach news into a single 0–100 risk score per vendor — work that otherwise requires three separate tools or a six-figure enterprise platform.
Open Postern's answer
Most vendor risk platforms — UpGuard, SecurityScorecard, BitSight — are priced for Fortune 500 procurement teams and gate access behind multi-month sales cycles. Open Postern delivers the same core continuous monitoring capabilities at a price point an MSP serving 20 SMB clients can actually afford, with a free tier that's genuinely usable and a sub-5-minute path from signup to a first actionable risk report. No demos required, no procurement process, no 12-month minimums.
Open Postern's answer
Open Postern started as a nights-and-weekends project aimed at a gap in the vendor risk monitoring market: small and mid-sized businesses get hit by vendor breaches just as often as enterprises, but the tools designed to protect them, UpGuard, BitSight, and SecurityScorecard, are priced for buyers ten times their size. Once the product had multi-tenant Agencies and Clients working, it was clear that the real operators of vendor risk for SMBs are MSPs, not the SMBs themselves. Open Postern is now positioned as the vendor risk platform built for the MSP channel... one that an MSP can resell to clients as a recurring service line without taking a margin hit.
