Based on 2025 benchmarks. Connect/ZIP's zEDC/zIIP optimization, native AES, and pricing make it the top alternative - especially fo PKZIP for z/OS users needing encryption without SecureZIP's premium or for companies just looking to cut costs without sacrificing performance. With Connect/MP Suite, replacing PKZIP for z/OS unloacks exclusive Connect/Hybird and Connect/Web features for hybrid integration and legacy modernization at no added cost.

FAQs: Replacing PKZIP with Connect/MP

How does Connect/ZIP reduce mainframe costs?

60% lower subscriptions, fixed per-MIPS rates, and superior zEDC/zIIP offload cut licensing, CPU, and storage costs, unlike basic ZIP tools with high overhead.

How is the 60% savings guaranteed?

Our subscription is 60% lower than PKWARE’s for equivalent licenses, validated by 2025 benchmarks and our pricing commitment.

How does Connect/ZIP outperform PKZIP?

It matches 95% compression but better leverages z15/z16 hardware for faster processing on specific datasets, reducing CPU and batch times.

How easy is the transition?

JCL and API compatibility means existing PKZIP for z/OS jobs and applications run unchanged in most cases. No disruption for operations, developers or end-users.

Why is zEDC/ZIIP and AES Encryption Critical?

zEDC and zIIP cut CPU usage by 50-70%, boosting z/OS cost and performance efficiency. Connect/ZIP’s AES-256 encryption, powered by CPACF hardware, delivers secure, compliant file sharing with minimal overhead and faster processing—unlike PKZIP for z/OS’s outdated, crackable ZIP legacy encryption, which lacks hardware acceleration and burdens CPUs.

What’s the benefit of fixed per-MIPS rates?

Predictable costs protect your budget from MIPS-related price hikes, unlike PKZIP for z/OS’s variable pricing.

How does no-payment-until-renewal work?

Use Connect/ZIP now, pay only at your next PKZIP for z/OS renewal, aligning with your budget cycle.
