Business-Critical Web Application Firewalls

Organizations are more dependent than ever on web applications for doing business with partners and customers, which means that protecting web applications has become business critical, something that all organizations should be taking into account.

Web Application Firewalls (WAF), therefore, are as relevant as ever, if not even more important than when they were first introduced for their ability to protect against or block a long list of common traditional web attacks such as SQL injection.

Although they have been around for decades, WAFs cannot be discounted as outdated or irrelevant because the WAF market is evolving, maturing, and growing with new vendors entering the market and driving innovation.

WAFs have evolved over time to distinguish between automated malicious bots and legitimate users, to detect abnormal activity, and to protect application program interfaces (APIs) in a variety of ways.

WAFs are essential to ensuring web application security, with the most advanced WAFs becoming more intelligent by incorporating machine learning to go beyond basic core capabilities to include bot management, API protection, Distributed Denial of Service (DDoS) protection, and even virtual patching.

As noted above, organizations are increasingly dependent on web applications as a means of doing business, and therefore it is important that they are familiar with the technologies that are available for protecting these business-critical applications in a wide range of industrial sectors, including finance.

Every organization should ascertain their dependency on web applications, review the security of those applications, and evaluate if there is a need to deploy new/additional Web Application Firewalls or update existing ones to meet current business and security needs.

“ A focus on Application Programming Interfaces (APIs) has been steadily growing, and we are seeing the market covering the protection of APIs in multiple ways such as API gateways, Access Management solutions, and now WAFs are also filling the gap with their own API protection combining Web Application and API Protection (WAAP) capabilities.”
