WPP, Security, and Compliance: What Changes for Enterprise IT
The reason to move off the legacy Windows print stack starts with five years of Print Spooler vulnerabilities. Microsoft has disclosed approximately 53 Print Spooler CVEs since the PrintNightmare cycle began in June 2021. CISA's Known Exploited Vulnerabilities catalog lists four of them as confirmed exploited in the wild. IBM's 2025 Cost of a Data Breach Report puts the US average breach cost at $10.22 million, the highest in the world, with healthcare at $7.42 million and financial services at $5.56 million. Print attack surface isn't the primary driver of those numbers, but it's one of the more easily eliminated ones.
WPP maps onto NIST SP 800-207 zero trust architecture directly. The traditional Windows print path violates several zero trust principles at once: shared print servers behave as implicit-trust hubs, third-party drivers run with elevated privileges, and the Spooler service accepts inbound RPC connections. WPP replaces all three. IPP over HTTPS uses encrypted outbound connections, the IPP Class Driver removes the shared-driver-trust assumption, and eliminating the local print server reduces the attack surface zero trust frameworks specifically call out.
That architectural change is increasingly showing up as a hard RFP requirement. For US federal customers, CMMC-bound defense contractors, and any team using NIST CSF or 800-53 as a baseline, "supports zero trust" is moving from a nice-to-have to a procurement gate. For HIPAA, PCI-DSS, SOX, and FedRAMP environments, WPP changes which controls apply and how endpoint hardening evidence gets documented. None of those mappings happens automatically. Each is an input to a compliance evaluation, not a substitute for one.
