Our Work

Recent Project Success

We work with the HQ IT departments of our clients, to ensure project success, coordinating with local vendors in Japanese, and explaining to HQ IT management in English. Here are a couple recent achievements.

Healthcare Firm

Take a client announcement page to production as a secure, bilingual website on a modern edge platform, with a validated inquiry form, tenant-native email delivery, and an access-controlled staff dashboard.

  • Rebuilt the page for correct Japanese rendering across browsers and devices while preserving the original design
  • Added a bilingual, accessible inquiry form with inline validation and spam-resistant contact handling
  • Routed submissions through the client's own Microsoft 365 tenant under least-privilege permissions, with every submission stored durably
  • Delivered a private, read-only staff dashboard behind Zero Trust access, with edge WAF, DDoS, and bot protection in front of the site

Finance Firm

Design and stand up a major, bilingual, fully managed cloud security operations center on Microsoft Sentinel, connecting the client's Microsoft and firewall data sources with detection rules, dashboards, and automated alert routing.

  • Built bilingual dashboards spanning incidents, identity, endpoint, email, and cloud apps, deployed via infrastructure-as-code
  • Deployed a curated set of high-severity detection rules with incident grouping to suppress alert-burst noise
  • Consolidated multiple security data sources — directory, extended detection and response, and a firewall — into workspace
  • Built an end-to-end automated alert-routing pipeline to a triage inbox with a severity-based classification policy, backed by an managed-service retainer

Finance Firm

Build, harden, and operate a major telemetry pipeline that streams AI-tool usage and firewall security events into a cloud SIEM, delivered across two phases with an managed-service retainer.

  • Provisioned and security-hardened a cloud collector (managed identity, just-in-time access, deny-by-default networking) behind a TLS-secured, WAF-protected ingestion endpoint
  • Delivered an AI-tool usage pipeline carrying hundreds of thousands of records with per-user and per-session attribution
  • Added firewall security-event ingestion plus a heartbeat alert if either data stream goes silent
  • Automated the retainer with scheduled jobs for connector-health digests, cost reporting, and schema-change tracking, retaining all operations
