Banking & Finance WAF API Shield DDoS Protection

BurjX kept its trading platform fast while blocking abuse and bots on Cloudflare.

How Brixio secured BurjX's crypto trading platform with Cloudflare WAF, API Shield, rate limiting, load balancing, and DDoS protection optimised for high-frequency trading traffic.

The challenge

BurjX operates a crypto trading platform in the UAE where milliseconds matter. The platform handles high-frequency transactions, real-time order books, and sensitive financial data. The security requirements are demanding: protect against volumetric attacks, API abuse, and automated bot traffic without introducing latency that would affect trading performance.

The pre-existing posture combined several risks:

  • Public-facing trading endpoints exposed to volumetric DDoS and L7 abuse, with no edge mitigation tuned for crypto traffic patterns.
  • API endpoints used by the trading client without API Shield protection, exposing them to enumeration, abuse, and exploitation.
  • No rate limiting on critical paths, leaving room for credential stuffing, scraping, and order-flow manipulation.
  • Single-origin exposure on critical trading endpoints, with no per-endpoint load balancing for resilience under burst loads.

What Brixio deployed

Discovery and security assessment

  • Detailed review of the application environment, edge security posture, and risk profile.
  • Recommendations aligned to Cloudflare best practices for crypto trading platforms.

WAF and application security

  • WAF tuning with custom rules addressing crypto trading-specific security patterns.
  • DDoS mitigation configured for volumetric and L7 attacks.
  • API Shield for API endpoint protection.

Rate limiting optimisation

  • Staged rollout (log-first, then enforce) to avoid disrupting legitimate trading traffic.
  • Controls tuned to reduce abuse, bots, and application stress without impacting real users.

Load balancing per endpoint

  • Per-endpoint load balancing configuration for availability and resilience.
  • Critical trading endpoints distributed for consistent performance under load.

Performance optimisation

  • DNS setup optimised for resolution speed.
  • SSL/TLS configuration aligned to encryption best practices.
  • CDN caching strategy reducing latency for global users.

Cloudflare Pages

  • Static site deployment for supporting web properties.

Knowledge transfer

  • Focused training session covering deployed controls, operational handling, and ongoing management.

Architecture

Trader, API client and bot traffic converge on a single Cloudflare edge enforcement plane before reaching the trading platform.

Results

After rollout, the trading platform was hardened against DDoS, bot abuse and API exploitation, with rate limiting and per-endpoint load balancing keeping legitimate trading traffic unaffected.

Sector perspective

Regulated digital-asset platforms need security that does not slow trading down.

Crypto trading platforms combine the security requirements of financial services with the performance demands of real-time systems. Rate limiting must be precise enough to block abuse without throttling legitimate trades. Load balancing must be granular enough to handle per-endpoint traffic patterns. In the UAE, VARA and the broader DFSA framework expect provable controls on application security, API protection and abuse prevention. This deployment shows that Cloudflare, configured by a specialist, can meet those demands without trading off latency.
