Key Features & Benefits

Block malicious IPs, minimize noise, focus on real signals.

Proactive Defense

Essential protective layer for Web Apps & VPS (Apache/Nginx). Blocks malicious traffic early, reducing reconnaissance and Shodan visibility.

High-Fidelity

Single verified source fed by global probes and self-hosted HIDS/SIEM. Prioritizes data reliability to minimize false positives.

Universal Compatibility

Standard RAW format. Vendor-agnostic (Split-list logic included). Fully portable for OpenCTI and MISP enrichment.

Freshness & Performance

Updates every 6 hours. 15-day rolling window to track short-lived threats. Enterprise-grade efficiency.

Core Objectives & Impact

Measurable improvements for your security posture.

Noise Reduction

Filters out 95% of malicious bot traffic, reducing log noise by 50%. Allows CIRs to focus on genuine anomalies rather than automated background noise.

Resource Optimization

Blocking threats at the perimeter prevents them from reaching app logic. Directly reduces CPU, RAM, and bandwidth usage, cutting infrastructure costs.

Automated Delivery

Zero manual intervention. Distributed via high-availability networks (GitHub, JSdelivr, BitBucket, GitLab) ensuring reliable access via standard Raw URLs.

Governance, Risk & Compliance (GRC)

Aligned with international security standards and regulatory frameworks.

Governance & Efficiency

Reduces operational noise by 50% and blocks 95% of bots. Enforces strict WAN-to-LAN config. Offers 5 official lists (up to 120k IPs) adapted to hardware limits.

Regulatory Alignment

Supports ISO 27001:2022 (A.8.20, A.5.7) and meets NIS2 Directive requirements for essential entities by providing structured risk management and resilience.

GDPR & Privacy

Operates outside GDPR scope (WAN-to-LAN). Blocked IPs are external malicious actors. No complex personal data processing documentation needed.

Risk Management

Rigorous behavioral analysis targeting < 2 false positives/month. High availability via 4 independent sources ensures continuous protection.

Structured Deployment & Feedback

Phased approach: Observation (Logging) → Activation (Blocking). Transparent process via GitHub for reporting false positives with resolution within 48 hours.
