Integrating WAF and DDoS Mitigation: A Powerful Alliance Against Cyber Threats

Website security is a top priority, particularly for organizations that rely on web assets directly for revenue. For most of the organizations, a Web Application Firewall (WAF) is the tool of choice to protect web assets. WAFs act as an important line of defense by filtering and monitoring HTTP traffic between web applications and the Internet, typically protecting apps from attacks such as cross-site scripting (XSS), cross-site request forgery (CSRF) and SQL injection (SQLi), among others. 

Powering the WAF's defense mechanisms are a core rule set designed to filter out malicious traffic, preventing data theft and unauthorized access. One of the key advantages of a WAF is its agility in policy modification, allowing for swift responses to evolving attack vectors.

Protecting Apps is Not Enough

While WAFs offer a certain level of protection against web application attacks, they fall short when it comes to protecting against L7 DDoS as well as volumetric attacks. Although WAFs play a vital role in filtering or blocking attempts to access servers or data, they are susceptible to state or resource exhaustion vulnerabilities. These vulnerabilities can have a substantial impact on the availability of defense strategies, leading to potential gaps in overall security.

To tackle these challenges, the synergistic combination of a WAF and DDoS mitigation emerges as an indomitable force. These two solutions complement each other seamlessly, working in unison to deliver all-encompassing protection against DDoS and web hacking. Together, they fortify your defenses, ensuring comprehensive security for your network, servers, and web applications.

Without such a DDoS solution in place, security teams may remain oblivious to ongoing attacks until the site goes offline, leaving them scrambling to restore services in real-time. The reactive approach not only diverts precious resources but also consumes crucial hours, or even days, resulting in staggering financial losses that can translate into millions of dollars of lost business.

Why the Need for Comprehensive DDoS Protection?

The relentless expansion and intricate nature of DDoS attacks have incontrovertibly redefined the contours of the security landscape. As organizations strive to realign their security frameworks to effectively counter the upsurge in DDoS attacks, it becomes increasingly apparent that the tools they wield must evolve in lockstep. While WAFs retain their significance in safeguarding web assets, the current threat landscape necessitates a comprehensive solution that fortifies multiple layers of both network infrastructure and applications.
