Strengthening Network Data Security Operations
Improving Collaboration, Security Governance and Operational Efficiency
Our customer’s Japan network data security function was responsible for safeguarding more than 45,000 users across group and insurance entities, while enforcing rules set by the US-based information security office. The operating model required close coordination between Japan and US teams; however, English-language communication gaps slowed escalations and limited the efficiency of cross-border issue resolution.
Furthermore, operational knowledge was fragmented across personal OneNote notebooks, creating inconsistent handovers, inefficient onboarding and unnecessary dependency on engineering teams for repeat queries. Without a centralised knowledge base, data security, networking and help desk teams had limited access to reliable, standardised guidance.
Post-maintenance website validation also created significant operational burden. Testing across proxies, business unit accounts and target destinations required manual logins, cache clearing, website checks and result recording, often taking 30–60 minutes per change. Policy enforcement around translation tools also needed strengthening, as unsanctioned external tools exposed live data to risk and had to be redirected to the approved internal Microsoft translation service.
Cross–Location Security Enablement and Operational Automation
Strengthening Knowledge Management, Policy Control and Delivery Assurance
TEKsystems deployed specialised network data security expertise to strengthen cross-location communication, centralise operational knowledge, enforce approved security practices and automate manual validation.
- Cross–Border Liaison: Established a dedicated English-language communication channel between Japan and US teams, improving escalation clarity, accelerating issue resolution and creating a more coordinated operating rhythm.
- Knowledge Centralisation: Consolidated fragmented operational artefacts into a continuously maintained Confluence knowledge base, replacing personal OneNote records with a shared source of truth for data security, networking and help desk teams.
- Policy Enforcement: Redirected end-user demand away from non-standard external tools towards the approved internal Microsoft translation service to reduce live data exposure risk.
- Testing Automation: Developed a Python-based automation tool for post-maintenance website validation across proxies, business unit accounts and target destinations, replacing repetitive manual checks with a faster and more standardised process.
- Networking Expertise: Introduced deeper networking capability into a security-led function, improving technical depth across web filtering, proxy, firewall and network security operations.
