Challenges

Ultra-Low Latency Requirements for Real-Time Trading

In securities trading, even the smallest delay can affect order timing, pricing accuracy, and investor outcomes. Vietcap needed to ensure consistently low latency across the country while processing real-time price feeds and high-frequency transactions.

Traffic Surges During Critical Trading Windows

At market open and during periods of volatility, traffic can spike up to 2 to 3 times normal levels. These sudden surges placed immense strain on infrastructure, increasing the risk of congestion, degraded performance, or service disruption at the moments users needed reliability most.

An Increasingly Complex Threat Landscape

As a platform handling sensitive financial data and high-value transactions, Vietcap also faced growing exposure to cyber threats. From disruptive attacks to attempts at account compromise, the company needed a proactive and adaptive approach to security. One that could protect without introducing friction for legitimate traders.

Solutions

To address both performance demands and security risks, Vietcap partnered with CDNetworks to implement an integrated solution that combines acceleration with multi-layered protection.

Strengthening Security to Protect Trading Operations

With CDNetworks’ Cloud Security 2.0, Vietcap establishes a unified security layer spanning both network and application traffic.

• Multi-layer DDoS Protection (L3/4 & L7)
  Leveraging CDNetworks’ 20 Tbps global scrubbing capacity, malicious traffic is filtered at the edge before reaching origin systems, protecting Vietcap’s infrastructure, even during large-scale attacks.

• Web Application Firewall (WAF)
  Machine learning-based inspection blocks OWASP Top 10 threats in real time, protecting Vietcap’s sensitive financial data and application integrity.

• Advanced Bot Management
  Behavioral analysis and device fingerprinting distinguish legitimate users from automated bots, reducing risks such as credential stuffing and account takeover, while maintaining a seamless trading experience for real users.

• Global Threat Intelligence
  Continuous telemetry across CDNetworks’ expansive global network allows Vietcap to detect emerging attack patterns and malicious IP activity at early stages.

Together, these capabilities enable Vietcap to build a more resilient and adaptive defense framework in response to an evolving threat landscape.

Accelerating Trading Performance Nationwide

On the performance side, Vietcap relies on CDNetworks’ in-country PoP coverage across Vietnam (integrated with Viettel, VNPT, and FPT) to deliver fast, stable trading experiences nationwide.

• Dynamic Web Acceleration
  TCP/IP optimization and intelligent traffic routing improve delivery efficiency for latency-sensitive dynamic requests, supporting faster responses for key user actions such as order placement and balance inquiries.

• Optimized Content Delivery
  Static assets used by VCI Mobile and Web Trading, including scripts and images, are delivered with lower latency through CDNetworks’ edge network, improving load speed and consistency even under unstable network conditions.

By optimizing how traffic is routed and delivered across its network, CDNetworks enables Vietcap to provide traders with a smoother, faster, and more reliable experience nationwide.
