What We Do

Simplify complex systems.
Turn technology into business results.

01

Solution Customization

Modify and extend commercial security solutions to fit enterprise environments. Ensure compatibility with existing infrastructure and develop features that enhance operational efficiency.
02

System Integration

Design and implement data flows between heterogeneous security systems such as SIEM, SOAR, and IAM. Apply integration methods that meet requirements including REST API, message queues, and real-time streaming.
03

Migration

Migrate data and logic from legacy systems to new platforms. Establish migration strategies that ensure business continuity while minimizing downtime.
04

Automation Build

Automate repetitive operational tasks to reduce human errors and increase response speed. Build CI/CD pipelines, infrastructure automation, and security orchestration.

Architecture

Layered Development Architecture

Design with scalable and maintainable structures. Each layer has clear responsibilities and can be tested and deployed independently.

Scalability

Independently scale each layer to flexibly respond to traffic increases and business growth.

Maintainability

Clear layer separation minimizes the impact of code changes and enables stable operations.

Security

Build multi-layer security systems by performing access control and data validation at each layer.

Integration

System Integration Process

Safely connect legacy and modern systems. Build integration layers that handle data transformation, protocol conversion, and security processing to ensure business continuity.
