ENTERPRISE-GRADE SECURITY
Core Capabilities of Our HSM Integration
Our integration bridges the gap between traditional payment security and blockchain innovation, delivering PCI DSS-compliant key management for your on-chain transactions.
01
PCI DSS-Compliant Key Vaulting
Secure your transaction signing keys within FIPS 140-2 Level 3 certified HSMs. We manage the full lifecycle—generation, storage, and rotation—ensuring compliance with financial industry standards.

HSM Integration: Build In-House vs. Partner with Chainscore
Choosing the right path for HSM integration impacts your security posture, time-to-market, and total cost of ownership. This table compares the key factors between a custom in-house build and partnering with our specialized team.
| Key Factor | Build In-House | Partner with Chainscore |
|---|---|---|
Time to Production | 6-12 months | 4-8 weeks |
Upfront Development Cost | $200K - $500K+ | $50K - $150K |
Security & Compliance Risk | High (unaudited, custom code) | Low (audited, battle-tested patterns) |
Ongoing Maintenance Burden | Your team (2+ FTE) | Fully managed (optional SLA) |
Expertise Required | HSM, PKCS#11, MPC, key lifecycle mgmt. | Provided by our team |
Hardware Vendor Lock-in | Yes (difficult to switch) | No (vendor-agnostic integration) |
Disaster Recovery Setup | Custom, complex implementation | Pre-configured, automated failover |
Audit & Compliance Readiness | Self-managed, lengthy process | Pre-audited, compliance-ready framework |
Total Cost of Ownership (Year 1) | $300K - $700K+ | $75K - $200K |

Technical Deep Dive
POS HSM Integration: Frequently Asked Questions
Get clear, specific answers about integrating Hardware Security Modules into your payment infrastructure. We address the most common technical and commercial questions from CTOs and engineering leads.
A standard integration with a Thales or Utimaco HSM into a new or existing payment system takes 2-4 weeks. This includes architecture review, secure key injection, API development, and end-to-end testing. Complex multi-chain or custom cryptographic protocol integrations can extend to 6-8 weeks. We provide a detailed project plan within the first 48 hours of engagement.
