STCLab is an enterprise software company that manages the entire journey of digital services — inflow, processing, validation, and scaling. We solve problems around malicious bots, traffic surges, API bottlenecks, incomplete performance testing, and Kubernetes operational complexity with a single technology portfolio.

Our principles

We keep searching for better answers

Rather than settling into the familiar, we create better answers through questions and challenges.

We take initiative and act with ownership

We proactively discover and solve problems, and see the ones we choose through to the end.

We start with customer value

We understand even our customers' unspoken needs and respond with better experiences.

What kind of company is STCLab?

STCLab is an enterprise software company that manages the full lifecycle of digital service operations — from traffic intake and processing to validation and scaling.

Through BotManager, NetFUNNEL, NetFUNNEL API, LoadTester, and Wave, we address malicious bots, traffic surges, API bottlenecks, gaps in performance testing, and Kubernetes operational complexity.

Traffic control expertise

Service failures don't begin at a single point

Before customers even reach your service, malicious bots and macros are mixed into the traffic.

When access spikes, requests exceed server capacity, and internal APIs and databases face bottlenecks and repeated retries.

Infrastructure must scale with changing traffic, and real environments must be thoroughly validated before deployment.

01

It's hard to distinguish real customers from automated traffic.

Malicious bots and macros undermine service fairness, distort data, and waste infrastructure resources.

02

Demand exceeds system capacity

When user and API requests exceed capacity, latency and outages follow.

03

Operating conditions are hard to predict

Virtual scenarios and manual thresholds alone can't fully reflect real usage patterns.

What We Do

User & automated traffic

BotManager

Separate malicious bots and macros from real users

NetFUNNEL

Control the entry of large-scale user traffic

NetFUNNEL API

Control the order, priority, and throughput of internal API requests

Applications & core systems

Wave

Kubernetes resource scaling, sizing, and diagnostics

LoadTester

Validate the full path with real user-behavior traffic

01

We control before failures happen

Rather than recovering after a system collapses, we manage the flow of traffic and requests first so capacity is never exceeded.

02

We bring visibility to invisible problems

We make malicious bot activity, API bottlenecks, resource waste, and performance limits visible and measurable with data.

03

We validate real environments, not assumptions

We judge based on real user behavior and operational data rather than statically written scenarios.

04

We automate repetitive operations

We reduce the repetitive work of manual threshold tuning, performance-test preparation, and Kubernetes resource management.
