Founding Corporate Member Technical SEO & GEO

BrandMeWeb: 100% Client Strategic Assets Shielded Across Automated GEO Workflows

Challenge: Agency AI pipelines process proprietary keyword intelligence, conversion logs, and client brand assets daily. Sending raw corpora to cloud foundation models risked competitor data contamination and client breach liability.

Architecture: @privacyscrubber/sdk with Node.js and LangChain BaseCallbackHandler middleware running in local volatile memory.

Canonical Reference Implementation Zero-Server Privacy

PrivacyScrubber: 1,000,000+ Sensitive Entities Sanitized Locally with Zero Server Overhead

Challenge: Enterprises and knowledge workers need client-side PII protection when pasting data into ChatGPT, Claude, and Gemini, but traditional proxy tools act as centralized honeypots requiring complex DPAs and security audits.

Architecture: Native WebAssembly (WASM) core running within Chrome MV3 service worker and headless @privacyscrubber/sdk package.

Sandbox Blueprint Clinical Healthcare & EHR

Apex Health Systems: 100% Cloud BAA Proxy Scope Elimination with Zero PHI Exposure

Challenge: Clinicians across 12 hospitals used commercial LLMs for discharge summaries, risking statutory HIPAA breach penalties and requiring complex Business Associate Agreements (BAAs) with AI vendors.

Architecture: @privacyscrubber/sdk browser extension deployed across 3,500 clinical Epic/Cerner workstations, de-identifying 18 PHI identifiers in local RAM before prompt dispatch.

Aegis Financial Technologies: PCI-DSS v4.0 Scope Elimination Across Real-Time Fraud Telemetry

Challenge: Banking fraud investigation copilot processed millions of payment transactions containing primary account numbers (PAN) and SWIFT BIC codes, creating massive PCI-DSS audit scope and cross-border Swiss FADP transfer liabilities.

Architecture: Proxy-wasm Envoy sidecar filter intercepting core banking payload streams, replacing payment entities with reversible surrogates before API dispatch.

Sandbox Blueprint B2B Enterprise SaaS

CloudScale Software Inc.: Enterprise CISO Win Rate Jumped from 12% to 94% on Copilot Launch

Challenge: Enterprise customers blocked CloudScale's new AI workflow copilot during security review due to fears of cross-tenant proprietary data contamination and lack of continuous tenant isolation evidence.

Architecture: @privacyscrubber/sdk integrated directly into Next.js Edge frontend API routes, masking customer names, financial IDs, and emails before LLM transmission.

Sandbox Blueprint Defense & Enclaves

Valkyrie Aerospace & Defense: SCIF AI Operations Deployed with Cryptographic Zero-Egress Attestation

Challenge: Defense technical specifications, munitions identifiers, and aerospace telemetry are subject to strict ITAR and European export controls, making commercial cloud AI strictly illegal without verified air-gap perimeters.

Architecture: Hardware-attested AWS Nitro Enclave C++ runtime executing ZTDS deterministic tokenization with cryptographic PCR hash verification and no network sockets.

CyberShield SOC Operations: 50,000+ Incident Alerts Triaged Without Exposing API Keys or Internal Subnets

Challenge: Tier-1 SOC analysts investigating breaches were pasting raw firewall logs, AWS IAM secrets, and internal network IP topologies into generative AI models, creating massive second-order attack vectors.

Architecture: Local CLI daemon (npx ztds-audit interceptor) and terminal wrapper filtering stdout/stdin before forwarding incident payloads to external AI analysis.

TalentHub Global PeopleOps: GDPR Article 9 Special Category PII Cleared for AI Interview Analytics

Challenge: Candidate resumes and interview transcripts contained sensitive health data, diversity disclosures, and national IDs. Processing these on third-party cloud AI violated GDPR Article 9 special category restrictions.

Architecture: Client-side React and Vue form hooks sanitizing applicant CVs and scorecards in the recruiter's browser before transmission to scoring models.

LearningCenterUsa.net: Zero-Egress Voice & Transcript Sanitization Under Cal. Penal Code § 632 & Illinois BIPA

Challenge: During realistic USCIS N-400, IRS CP2000, and US Bank Fraud practice calls, users frequently blurt out their real Social Security Numbers, USCIS A-Numbers, and payment card digits into the microphone instead of test reference numbers.

Architecture: Client-side @privacyscrubber/sdk volatile RAM interceptor inside the Web-Phone widget sanitizing SpeechRecognition transcripts into reversible tokens ([US_SSN_TOKEN_1]) prior to scoring.
