Azure WAF Pros and Cons
These are the pros and cons of Azure WAF from reviews by people who have used it.
Pros | Cons |
Azure WAF offers comprehensive protection against OWASP Top 10. | No Zero-Day pre-emptive protection as it based on signatures |
It gives you real-time visibility and security alerts to deter threats. | Very high false positive rate. Requires manual tuning process to get rid of false positives. |
Azure WAF offers REST API support to automate DevOps processes. | |
Can detect and block malicious bots and DDoS attacks. | |
Azure WAF is a cloud-native service that safeguards APIs and web applications from web-exploits techniques like SQL injection and cross-site scripting. It allows you to create a WAF policy that can be applied to Application Gateway or Azure Front Door to manage rules and control access to your web application.
Users can deploy Azure WAF in minutes with pre-configured managed rules that extend beyond OWASP Top 10.
Here are some of the features of Azure WAF:
Enable bot management rules. The Azure WAF bot protection rule set categorizes bots based on whether they are good, malicious, or unknown. It will block bad bots and allow good bots like search engine crawlers.
Protect your web application with managed rules. When combined with an updated ruleset, the WAF will increase security, reduce false positives and improve performance.
Agentless deployment. You can easily deploy the Azure Web Application Firewall without using any software agent. Create a rule set that meets your security needs and apply them to safeguard your application.
Improve security and performance. You can deploy Azure WAF in Azure Front Door for advanced security features and scalability and speed up the delivery of apps to your users worldwide.
Cloudflare WAF Pros and Cons
These are Cloudflare WAF pros and cons from reviews by people who have used it.
Pros | Cons |
Cloudflare WAF is easy to configure and use. | Setting custom rules can be difficult for beginners. |
You can use Cloudflare WAF to protect your web application from SQL injection, cross-site scripting, and malware. | Requires manual tuning process to get rid of false positives. |
It offers protection against DDoS, OWASP Top 10, and malicious bot attacks. | No Zero-Day pre-emptive protection as it based on signatures |
Cloudflare WAF prevents account takeover and credentials theft. |
Cloudflare WAF protects your website or application from common vulnerabilities like SQL injection, cross-site scripting, and forgery requests. Also, it keeps your application and APIs secure and productive and detects anomalies and malicious payloads while monitoring for browser chain attacks.
Cloudflare Managed Ruleset protects against zero-day vulnerability and OWASP Top 10 attack techniques while offering protection against bot attacks. It has an Advanced Rate limiting that stops abuse, DDoS attacks, and malicious attempts with API-centric control.
Here are some features offered by Cloudflare WAF:
Rate limiting rules. Users can define rate limits for incoming requests that match an expression and the action to take when the limits are reached.
Managed rule set. You can enable the pre-configured Managed Rulesets to get immediate protection and adjust the behavior of managed rules.
Custom rules. Users can create custom rules to safeguard their website, application, or APIs from malicious incoming traffic.
Stop account takeover. With Cloudflare WAF, you can prevent abusive logins and attackers from taking over your user accounts.
Bot and API protection. Cloudflare protects against bot attacks that can harm your web application. Also, it keeps APIs safe with API discovery, mTLS, anomaly detection, and schema validation.
open-appsec Pros and Cons
Are you looking for a way to block attacks on your web application before they happen? open-appsec uses machine learning to continuously detect and preemptively block threats before they can do any damage. Our code has also been published on GitHub, and the effectiveness of our WAF has been successfully proven in numerous tests by third parties. Try open-appsec in the Playground today.
open-appsec Pros | open-appsec Cons |
Automatically detects and prevents threats using machine learning. | It is a new security product. |
Offers a full IPS Engine that continuously monitors traffic to prevent intrusion. | There isn't a lot of information about it on the internet. |
Integrates seamlessly with modern environments like the public cloud. | It has a small community of users. |
Easy to set up and manage. | |
open-appsec is the third web application firewall we will compare in this blog post. It is a fully automated WAF and API security solution that uses machine learning to automatically detect and prevent attacks like OWASP Top 10, zero-day attacks, and malicious bots.
Its ML-based engine continuously analyzes HTTP/S requests and filter traffic as they visit your website.
Also, it blocks attacks like Text4Shell, Log4Shell, and Spring4Shell by default, with no updates required due to its preemptive nature. open-appsec is free to use and expand upon since it is open-source, and the code is available on GitHub. Premium support and features like an anti-bot and log storage in the cloud are also available.
You can easily deploy it as an add-on to Kubernetes Ingress, Envoy, NGINX, and API Gateways to provide web app and API security with complete protection and easy management required by modern workloads.
Getting started with open-appsec is easy. You can play around the playground to learn how to test and deploy the tool.
Depending on your environment, you can use the Kubernetes or NGINX playground to learn how to:
Attack the demo web application by doing a simple SQL injection.
Deploy open-appsec on the NGINX or Kubernetes environment.
Attack the web application again to ensure the security is implemented and effective.
Connect to the SaaS Web-Based Management.
