Secure Your Origin
High-performance origin security with advanced caching, robust protection, and seamless scalability for any infrastructure.
How Varnish Secures Your App Server
Varnish Enterprise provides a robust, highly adaptable software solution to secure origin servers while delivering unmatched content delivery performance and reliability.
As an HTTP accelerator, programmable reverse proxy, and caching platform, Varnish sits between end users and origin servers, intercepting and processing HTTP requests. It enables intelligent traffic routing, request filtering, and response handling through the powerful Varnish Configuration Language (VCL).
By accelerating HTTP responses, reducing server load, and offering programmable request management, Varnish functions as both a performance enhancer and a security layer for origin servers.
Its capabilities include granular request handling, DDoS mitigation, API protection, and encrypted communications, making it a versatile solution for securing modern, distributed infrastructures.
Intelligent Caching and Traffic Management
High traffic volumes, whether malicious or legitimate, can overwhelm origins, leading to performance degradation and increased costs. Varnish Enterprise features:
Dynamic Caching:
- Accelerate delivery by caching frequently accessed and personalized content to significantly reduce backend load and minimize latency.
- Ensure fast, reliable user experiences, even during traffic spikes.
Origin Shield:
- A centralized caching layer that acts as a protective buffer, reducing backend requests and shielding the origin from spikes and attack vectors.
Traffic Filtering:
- Malicious Traffic Blocking: Utilize advanced edge shielding, rate limiting, and geo-blocking to neutralize threats before they reach your infrastructure.
- Fair Request Management: Throttle abusive requests while maintaining seamless performance for legitimate traffic, ensuring reliable access for users.
Comprehensive API and Application Security
APIs and web applications are prime targets for credential stuffing, brute force, bot attacks, and major vulnerabilities. Varnish Enterprise features:
API Protection:
- Secure APIs with mutual TLS (mTLS) authentication and encrypted communication for safe data exchanges.
- Enforce granular API access controls with custom security rules through VCL scripting.
Bot Mitigation:
- Identify and block malicious bots in real-time while ensuring legitimate users experience uninterrupted service.
- Protect dynamic content and sensitive endpoints from automated threats.
Application-Level Threat Protection:
- Block OWASP Top 10 vulnerabilities with a customizable Web Application Firewall (WAF).
- Proactively shield your applications from SQL injection, XSS, and other sophisticated exploits.
Threat Protection and Compliance
Enhanced Content Filtering and Threat Prevention
Content Sanitization and Filtering
- Inspect and reject requests containing invalid headers, malformed URLs, or disallowed parameters to block potentially harmful or unauthorized traffic.
Body Inspection
- With specialized VMODs like xbody, scan HTTP request or response bodies for malicious payloads, inappropriate content, or compliance violations.
IP Allowlisting and Denylisting / Access Control
- Enforce strict access control policies using VCL logic to allow or block specific IP ranges, ensuring only trusted clients interact with your origin server.
Content Spoofing and Cache Poisoning Prevention
- Prevent attackers from injecting malicious content into the cache using strict cache key management and advanced validation logic.
Monitoring and Logging for Traffic Analysis
- Gain actionable insights into traffic patterns, attack attempts, and performance bottlenecks with robust monitoring and logging tools.
- Enable precise threat detection and response through real-time traffic analysis.
End-to-End Encryption and Compliance
Protecting sensitive user data while meeting diverse compliance requirements across geographic regions and multi-cloud environments can be complex and costly.
End-to-End Encryption:
- TLS Termination. Offload encryption and decryption processes to Varnish, reducing origin server overhead.
Data Integrity and Geo-Blocking
- Secure all communications with HTTPS to ensure data authenticity and privacy.
- Comply with data sovereignty laws by restricting access based on geographic location.
WAF and ACLs:
- Built-in tools to enforce access control and block threats in real-time.
Unified Security Policies:
- Applies consistent caching and security rules across cloud, on-premises, and hybrid setups.
Cloud-Native Integration:
- Fully compatible with Kubernetes and major cloud providers (AWS, Azure, GCP), enabling seamless deployment across multi-cloud and hybrid architectures.
