AWS WAF vs NetScaler Web Application Firewall comparison

AWS Web Application Firewall (WAF) is a firewall security system that monitors incoming and outgoing traffic for applications and websites based on your pre-defined web security rules. AWS WAF defends applications and websites from common Web attacks that could otherwise damage application performance and availability and compromise security.

You can create rules in AWS WAF that can include blocking specific HTTP headers, IP addresses, and URI strings. These rules prevent common web exploits, such as SQL injection or cross-site scripting. Once defined, new rules are deployed within seconds, and can easily be tracked so you can monitor their effectiveness via real-time insights. These saved metrics include URIs, IP addresses, and geo locations for each request.

AWS WAF Features

Some of the solution's top features include:

• Web traffic filtering: Get an extra layer of security by creating a centralized set of rules, easily deployable across multiple websites. These rules filter out web traffic based on conditions like HTTP headers, URIs, and IP addresses. This is very helpful for protection against exploits such as SQL injection and cross-site scripting as well as attacks from third-party applications.

• Bot control: Malicious bot traffic can consume excessive resources and cause downtime. Gain visibility and control over bot traffic with a managed rule group. You can easily block harmful bots, such as scrapers and crawlers, and you can allow common bots, like search engines and status monitors.

• Fraud prevention: Effectively defend your application against bot attacks by monitoring your application’s login page with a managed rule group that prevents hackers from accessing user accounts using compromised credentials. The managed rule group helps protect against credential stuffing attacks, brute-force login attempts, and other harmful login activities.

• API for AWS WAF Management: Automatically create and maintain rules and integrate them into your development process.

• Metrics for real-time visibility: Receive real-time metrics and captures of raw requests with details about geo-locations, IP addresses, URIs, user agents, and referrers. Integrate seamlessly with Amazon CloudWatch to set up custom alarms when events or attacks occur. These metrics provide valuable data intelligence that can be used to create new rules that significantly improve your application protections.

• Firewall management: AWS Firewall Manager automatically scans and notifies the security team when there is a policy violation, so they can swiftly take action. When new resources are created, your security team can guarantee that they comply with your organization’s security rules.

Reviews from Real Users

AWS WAF stands out among its competitors for a number of reasons. Two major ones are its user-friendly interface and its integration capabilities.

Kavin K., a security analyst at M2P Fintech, writes, “I believe the most impressive features are integration and ease of use. The best part of AWS WAF is the cloud-native WAF integration. There aren't any hidden deployments or hidden infrastructure which we have to maintain to have AWS WAF. AWS maintains everything; all we have to do is click the button, and WAF will be activated. Any packet coming through the internet will be filtered through.”

Only NetScaler uses a one-pass architecture for traffic processing that enables it to perform web application firewall (WAF) inspection in a single pass. This significantly reduces the latency of each request for optimal application performance. And because advanced WAF capabilities come built in with NetScaler, there’s no need to purchase a separate WAF solution.

For the most comprehensive protection from OWASP Top 10 attacks to zero-day exploits, NetScaler WAF employs a hybrid security model that incorporates policies, profiles, and signatures to protect against known and unknown web application attacks.

To save you time, NetScaler WAF uses automated learning, called dynamic profiling, to understand how a protected application works. By using a repetitive-pattern filter, NetScaler WAF adapts to the application even as developers continue to develop and deploy it, so it is always protected.
