description Google Cloud Armor Overview
Google Cloud Armor leverages the same security infrastructure that protects Google's own services, such as Search and YouTube. It offers powerful, adaptive protection that uses machine learning to automatically detect and block malicious traffic patterns. Cloud Armor is highly effective for applications hosted on Google Cloud Platform, providing robust WAF capabilities and DDoS mitigation that scales effortlessly. Its 'Adaptive Protection' feature is a standout, as it learns the baseline traffic of your application and alerts you to anomalies, significantly reducing the time required to respond to new threats.

help Google Cloud Armor FAQ
How does Google Cloud Armor protect against DDoS attacks?
Cloud Armor leverages Google's global infrastructure to absorb volumetric DDoS attacks at the edge before they reach your resources. It provides always-on protection with multi-layer defenses including network-layer filtering, application-layer rules, and ML-powered Adaptive Protection for automatic threat mitigation.
What is the pricing model for Google Cloud Armor?
Cloud Armor uses a pay-per-policy model with approximately $5 per security policy per month plus $0.75 per 10,000 requests. The Adaptive Protection feature requires an additional premium fee. A free tier with limited WAF rules is available for basic protection needs.
Can Google Cloud Armor block traffic from specific countries?
Yes, Cloud Armor supports geo-based access control allowing you to allow or deny traffic from specific countries or regions using IP address mapping. You can also create custom rules combining geographic filters with other conditions like URL paths or request attributes.
How does Cloud Armor integrate with Cloud Load Balancer?
Cloud Armor attaches directly to Cloud Load Balancer as a security enforcement point, inspecting all incoming traffic before it reaches backend services. This integration provides automatic scaling with your load balancer and ensures consistent policy enforcement across all regional deployments.
What are the differences between Cloud Armor Standard and Adaptive Protection?
Standard tier includes basic WAF rules, rate limiting, and geo-blocking. Adaptive Protection is a premium tier that adds ML-powered real-time attack detection, automatic rule generation during emerging threats, and post-attack analytics. It's recommended for high-value applications facing sophisticated threats.
