WAF, Cloudflare, and Fortinet: A Comparative Battle Record in Defending Against DDoS Attacks

In today’s digital world most organizations are facing cyber attacks, a Distributed Denial of Service (DDoS) attack is one of the most dangerous and persistent threats. First, let’s understand what a DDoS attack is.

A DDoS (Distributed Denial of Service) attack is a type of attack that happens when a network is flooded with traffic from multiple sources, which makes it difficult or impossible for users to access a website or service.

In the market, there are various tools or services available that offer protection against the DDoS attack but here are the three most popular DDoS protection services that we will be discussing in this blog and each one of these solutions has its own unique strengths and weaknesses.

We will be discussing which one would be the best solution for your business depending on your infrastructure, security needs, and budget. Now, let’s take a deep dive to understand each of the solution offerings in the battle against DDoS attacks.

AWS WAF (Web Application Firewall)

Best for: If you are an AWS cloud user and looking for a cloud-native DDoS protection service then go for AWS WAF this will easily integrate into your existing AWS environment and provide you protection against DDoS attacks.

Key Features:

• Protection Against Web Attacks: AWS WAF will protect web applications against DDoS attacks by filtering the traffic according to the rules created. It allows the customers to create their own custom rules according to their organization’s needs.
• Web traffic filtering: AWS WAF protects layer 7 i.e. application layer threats. With its customizable rules creation feature, we can filter the IP addresses, HTTP headers, HTTP bodies, and URI strings from a web request.
• Flexible Integration With AWS Services: AWS WAF offers seamless integration with other AWS services like Load balancer, Amazon EC2, CloudFront(CDN), etc.
• Global Scalability: AWS WAF is a Global service in AWS which means it is available across various AWS regions and also can be integrated with AWS CloudFront (CDN) to make sure that the application is protected globally with low-latency traffic filtering.

Why Choose AWS WAF?

• Native AWS Integration: AWS WAF can be easily integrated with other AWS services which makes it an excellent choice if the application is hosted in AWS Cloud.
• Scalability: It scales automatically and easily handles the increasing traffic volumes.
• Cost-Effective: Its pay-as-you-go pricing model makes it a cost-effective solution for those organizations that already have their infrastructure in the AWS environment.

Limitation:

• AWS WAF is only applicable for those applications that are deployed in the AWS environments, It does not support multi-cloud or on-premise infrastructure.

Cloudflare

Best for: If the Organization has a multi-cloud or hybrid setup and requires a solution that can easily integrate with their multiple platforms and offers them a global DDoS protection service then they should consider Cloudflare.

Key Features:

• DDoS Protection Across All Layers: Cloudflare offers a comprehensive DDoS protection service for Layer 3/4 (network layer), and 7(application layer) in the OSI model to ensure it is safe against volumetric attacks.
• Global CDN and Edge Network: Cloudflare is one of the largest content delivery networks (CDN) platforms globally with over 300 locations. This will allow Cloudflare to protect against the largest DDoS attacks through its global network.
• Unlimited DDoS Mitigation: With Cloudflare, the organization is protected from any form of DDoS attacks of any size or duration. It scales automatically by the size of the attack and provides robust protection without making any configuration changes.
• Simple Deployment: Cloudflare’s DDoS protection can be deployed via DNS changes which makes it easy to protect the assets no matter where they are hosted whether on-premise or multi-cloud environment.

Why Choose Cloudflare?

• Platform Agnostic: Cloudflare offers seamless protection no matter if your organization has a multi-cloud or on-premise setup.
• Ease of Use: Cloudflare’s interactive interface makes it easy to use and manage for users who have limited cybersecurity expertise.
• Enterprise-Grade DDoS Protection: Through its automatic detection and mitigation feature. It is ideal for organizations that suffer from large volumetric attacks.

Limitation:

• Cloudflare’s higher-tier DDoS protection is less cost-effective for smaller organizations that do not require enterprise-level protection.

Fortinet (FortiWeb + FortiDDoS)

Best for: Organizations that require deep control in their DDoS defense strategy and have hybrid and on-premise setups should consider Fortinet.

Key Features:

• Behavioral-Based Detection: It uses machine learning algorithms and behavior-based detection to protect against DDoS attacks. It analyzes the traffic pattern and automatically adjust the thresholds to block the malicious traffic.
• Hardware Acceleration: FortiDDoS uses hardware-based ASIC processing that provides high-speed protection with minimal latency which makes it highly effective in high-traffic volume environments.
• On-Premise and Hybrid Protection: Fortinet offers both on-premise and hybrid infrastructure a wide range of protection against DDoS which makes it a good choice for organizations that has this kind of setup.

Why Choose Fortinet?

• Deep Packet Inspection: It offers a granular level of control on traffic filtering with its deep packet inspection and behavior-based traffic analysis feature.
• Comprehensive Security: Fortinet’s suite of security tools extends beyond just DDoS protection, offering full enterprise security solutions, including firewalls, intrusion prevention systems (IPS), and secure SD-WAN.
• High-Performance Hardware: If you are a large organization with consistent traffic loads then Fortinet’s hardware appliances offer unmatched performance with minimal latency.

Limitations:

• Fortinet’s solution needs upfront investment in their hardware appliances which makes it less accessible for small-scale businesses. Also, its configuration requires a deep level of understanding of network security.

Final Showdown: Which One Should You Choose?

Each one of these solutions has its advantages in different environments, your choice should always depend on your infrastructure, attack risk, and of course budget.

• Choose AWS WAF only if you are completely into the AWS environment and require a cloud-native solution that seamlessly integrates and scales with your AWS resources.
• Choose Cloudflare only if your organization has a hybrid or multi-cloud environment that requires a global solution to protect against large-scale attacks with ease.
• Choose Fortinet only if you are a large-scale organization that requires full control over the security infrastructure with its deep packet inspection, on-premise protection, and advanced DDoS mitigation hardware features.
