1,800 Stores. One Broken PKI. A Security Foundation Rebuilt to Scale.

[cs_hero title_before = "1,800 Stores." title_colored = "One Broken PKI." title_after = "A Security Foundation Rebuilt to Scale." industry = "Retail (Farm, Ranch & Rural Supply)" engagement_type = "PKI Assessment & Remediation Roadmap" download_url = "https://preview.encryptionconsulting.com/wp-content/downloads/case-studies/One-Broken-PKI-A-Security-Foundation-Rebuilt-to-Scale.pdf" ] [cs_excerpt] How Encryption Consulting found the cryptographic and governance gaps in a national retail chain's PKI and laid out a roadmap to fix them. [/cs_excerpt] [cs_profile_desc] One of the largest farm and ranch retail chains in the United States, with 1,800+ stores across 40+ states serving recreational farmers, ranchers, and rural homeowners. [/cs_profile_desc] [cs_at_a_glance stat1="60%+" label1="Weak keystores identified across the environment" stat2="2048-bit+" label2="New minimum key length standard" stat3="FIPS 140" label3="HSM standard for CA key generation" stat4="1" label4="Prioritized remediation roadmap delivered" ] [/cs_hero] [cs_challenges desc=”The retail chain’s PKI had outgrown its governance and visibility. Certificates went untracked, keys were poorly protected, and a single compromise could spread across thousands of stores before anyone noticed.”] [cs_challenge icon=”0″ title=”No governance or policy backbone” tag=”GOVERNANCE”] No CP/CPS or governance program for private/public CAs. Core documentation, change management, and Business Impact Analysis are all missing. [/cs_challenge] [cs_challenge icon=”1″ title=”Cryptographic standards dangerously outdated” tag=”CRYPTOGRAPHY”] 60%+ of keystores on 1024-bit keys with no HSM protection, misaligned Root CA signing, an over-long Root CA validity period, undefined path length, and missing CA Policy files. [/cs_challenge] [cs_challenge icon=”2″ title=”Certificate lifecycle managed by email” tag=”LIFECYCLE”] No CLM, renewals tracked by email with no inventory or CSR approval, templates issued without key recovery, and Supply Chain importing self-signed certs into MDM without chain validation. [/cs_challenge] [/cs_challenges]
[cs_quote author=”Encryption Consulting Assessment Team” role=”ENTERPRISE CHALLENGES SUMMARY: ENCRYPTION CONSULTING · PKI ASSESSMENT”] The chain’s PKI had drifted into a state where governance, cryptography, and lifecycle management were all running on assumption rather than control. [/cs_quote]

[cs_solutions desc=”Three workstreams covered the findings. PKI maturity was scored against the CMMI (Capability Maturity Model Integration) framework, and recommendations were ranked by risk and sequenced into a phased roadmap.”] [cs_solution title=”Cryptographic & Infrastructure Foundation” image_url=”https://ecwebsitedata.blob.core.windows.net/encryption-consulting-website-data/2026/06/One-Broken-PKI-A-Security-Foundation-Rebuilt-to-Scale-solution-banner-1.jpg”] Move to Windows Server 2022+ on FIPS 140-2/3 Level 3 HSMs, enforce 2048-bit minimums, realign Root CA signing, and roll out a formal CP/CPS with CA Policy files and Microsoft Strong Certificate Mapping (SID). [/cs_solution] [cs_solution title=”Certificate Lifecycle Automation” image_url=”https://ecwebsitedata.blob.core.windows.net/encryption-consulting-website-data/2026/06/One-Broken-PKI-A-Security-Foundation-Rebuilt-to-Scale-solution-banner-2.jpg”] Deploy CLM for automated discovery and renewal, a formal CSR approval workflow, and a central template inventory. Standardise issuance with key recovery enabled, and enforce chain validation for external certs entering MDM. [/cs_solution] [cs_solution title=”Access Control & Key Management” image_url=”https://ecwebsitedata.blob.core.windows.net/encryption-consulting-website-data/2026/06/One-Broken-PKI-A-Security-Foundation-Rebuilt-to-Scale-solution-banner-3.jpg”] Enforce least privilege, separation of duties, and TPI across all PKI roles. Add formal key destruction, recovery, and revocation procedures, a managed key inventory, and oversight of compromised certificates. [/cs_solution] [cs_solution title=”Operational Resilience & Governance” image_url=”https://ecwebsitedata.blob.core.windows.net/encryption-consulting-website-data/2026/06/One-Broken-PKI-A-Security-Foundation-Rebuilt-to-Scale-solution-banner-4.jpg”] Forward CA logs to SIEM with auditing, health monitoring, and quarterly config reviews. Stand up a governance program, RACI, DR, risk/compliance monitoring with RTOs, plus a data sovereignty assessment and PKI/HSM training. [/cs_solution] [/cs_solutions]
[cs_quote direction=”rtl” author=”Encryption Consulting Assessment Team” role=”ENGAGEMENT SUMMARY: ENCRYPTION CONSULTING · PKI SERVICES”] The result is a PKI that is governed, automated, and cryptographically sound, where it used to be reactive and undocumented. [/cs_quote]

[cs_outcomes desc=”The roadmap gave the retail chain a prioritized plan to close cryptographic gaps, set up governance, and keep PKI operations running reliably across 1,800+ stores.”] [cs_outcome title=”Cryptographic risk scoped for elimination”] 60%+ of keystores on weak 1024-bit keys flagged; roadmap mandates 2048-bit minimums, HSM protection, least privilege, and formal key destruction. [/cs_outcome] [cs_outcome title=”A path to operational continuity”] Automated CLM ends missed renewals across 1,800+ stores; SIEM, health monitoring, and formal revocation keep every certificate and key accounted for. [/cs_outcome] [cs_outcome title=”Governance and capability foundations laid”] CP/CPS, RACI, DR, and risk monitoring with RTOs deliver accountability; data sovereignty assessment plus PKI/HSM training build lasting in-house expertise.
