16 Ways Cloud WAFs are Better than On-Premise WAFs

3 min readOct 27, 2023


A Web Application Firewall (WAF) is a security solution designed to protect web applications from various attacks, including SQL injection, cross-site scripting (XSS), and others.

There are two types of WAF: on-premise and cloud-based.

Cloud WAF Versus On-Premise WAF

Here are some advantages of Cloud WAF over on-premise WAF:

1. Scalability

Cloud-based WAFs can easily scale up or down based on demand, whereas on-premise WAFs are limited by the hardware capacity they run on.

2. Lower Cost

Cloud WAFs have lower upfront costs because they don’t require purchasing and maintaining hardware and software. With cloud WAF, organizations can pay for what they use without worrying about hardware replacement or software upgrades.

3. Easy deployment and management

Cloud WAFs can be deployed and managed easily through a web-based interface, allowing quicker implementation and reduced reliance on IT resources.

4. Global coverage

Cloud-based WAFs typically have more points of presence (PoPs) worldwide, providing broader coverage and better protection against attacks from different locations.

5. Automated security updates

Cloud WAFs receive automatic security updates and patches, ensuring the system is updated with the latest security measures.

6. Integrated with other cloud security solutions

Cloud WAFs can be integrated with other cloud security solutions, such as content delivery networks (CDNs), DNS providers, and other security services, which provide additional layers of security and increased visibility into attacks.

7. Flexibility

With cloud WAF, you have more flexibility to configure the solution to meet your specific needs. You can adjust policies and rules and easily integrate them with other security tools or services.

8. Better Performance

Cloud WAFs can be optimized for performance and can easily handle large volumes of traffic. They also have built-in load-balancing capabilities, which can improve the availability and reliability of your web applications.

9. Improved Security

Cloud WAFs can provide better security than on-premise WAFs because they have access to more threat intelligence data and can leverage machine learning and AI to detect and respond to new threats.

10. 24/7 Monitoring and Support

Cloud WAF providers typically offer 24/7 monitoring and support, ensuring your web applications are protected around the clock.

11. Regulatory Compliance

Cloud WAFs can help you meet regulatory compliance requirements by providing features such as data encryption, access controls, and audit logs.

12. Automatic backups and disaster recovery

Cloud WAFs can provide automatic backups and disaster recovery capabilities, ensuring that your web applications are protected in case of a disaster or outage.

13. Predictable costs

Cloud WAFs typically offer a pay-as-you-go pricing model, which can help you manage costs more effectively. You only pay for the resources you use and can scale up or down as needed.

14. Vendor support

Cloud WAF providers typically offer robust vendor support, including access to security experts and technical support teams. This can be particularly useful for organizations without dedicated IT security teams.

15. Smaller Team

Cloud WAF ensures that you can achieve your security needs with the smaller team as there is no need for a separate team to maintain WAF infra, and with the right vendors, maintenance of WAF is also taken care of by vendors.

16. DDoS Protection

DDoS is an attack where many requests are sent to use up server resources so that web application is unavailable for legit users. On-prem cannot protect against DDoS as they cannot scale. With its ability to efficiently handle and prevent DDoS attacks, Cloud WAF is the top solution for DDoS protection.
