The Challenge: Operating Cloudflare at Scale

Cloudflare generates high-volume telemetry across multiple layers:

• WAF managed rule triggers and custom matches
• Bot scores and automation signals
• Rate limiting actions and thresholds
• API Shield events (validation failures, abuse patterns)
• Edge performance metrics and latency trends

Security teams frequently encounter:

• Alert fatigue from noisy events
• Difficulty correlating cross-layer signals
• False positives impacting legitimate users
• Reactive troubleshooting of traffic anomalies
• Limited visibility into business-critical APIs

Nexarq AI Analytics: Architecture Overview

Nexarq’s platform is built natively on Cloudflare and ingests telemetry across security and performance layers. AI-driven analysis correlates events and detects anomalies to provide prioritized insights.

Core Workflow

1. Cloudflare generates security & performance signals.
2. Nexarq aggregates and correlates telemetry.
3. AI models detect anomalies and deviations.
4. Alerts and dashboards provide actionable insights.

Cross-Layer Signal Correlation

Traditional monitoring tools analyze signals in isolation. Nexarq correlates Cloudflare signals to identify meaningful patterns.

Example correlations

• WAF blocks + bot score spike → automated attack detection.
• Rate limiting triggers + latency increase → traffic surge affecting performance.
• Traffic drop + new rule deployment → potential false positive.

This correlation significantly reduces investigation time.

AI-Based Anomaly Detection

Nexarq establishes behavioral baselines and detects deviations such as:

• Sudden traffic spikes or dips
• Unusual bot activity targeting specific APIs
• Unexpected increases in WAF rule triggers
• Behavioral anomalies in partner integrations
• Regional latency deviations

This enables proactive detection of threats and misconfigurations.

Business-Centric Monitoring

Nexarq aligns monitoring with business priorities by focusing on:

• Critical APIs and revenue paths
• Partner integrations and B2B traffic
• Customer experience impact
• Geographic traffic trends

This ensures security operations focus on business impact, not just events.

Intelligent Alerting & Noise Reduction

Instead of alerting on every event, Nexarq provides:

• Context-aware alerting
• Multi-signal correlation thresholds
• Business-impact prioritization

Example: Alert only when WAF blocks increase on a critical API and error rates rise. This reduces alert fatigue while improving response accuracy.

Performance Observability Across the Edge Path

Nexarq provides visibility across the full request lifecycle:

• Client → Cloudflare edge latency
• Edge → origin latency
• Regional performance variations
• API response time anomalies

This enables rapid identification of:

• Origin bottlenecks
• Routing inefficiencies
• Regional degradation
• Misconfigured caching policies

Operational Benefits

By integrating AI-driven analytics with Cloudflare telemetry, Nexarq enables:

1. Faster root cause analysis
2. Reduced false positives in WAF policies
3. Improved protection for critical APIs
4. Enhanced visibility into partner traffic behavior
5. Proactive detection of performance degradation

Use Cases

Protecting Critical APIs

Detect abnormal traffic patterns targeting high-value endpoints and trigger preemptive mitigation.

Optimizing WAF Policies

Identify managed rule false positives and recommend tuning actions.

Monitoring B2B Integrations

Detect anomalies in server-to-server traffic behavior.

Investigating Traffic Anomalies

Correlate traffic dips or spikes with security rules or performance changes.

Conclusion

Cloudflare provides robust edge security and performance capabilities, but operationalizing these controls at scale requires advanced analytics and correlation.

Nexarq’s AI-powered analytics platform transforms Cloudflare telemetry into actionable intelligence, enabling security teams to detect threats faster, reduce operational noise, and maintain optimal performance.
