Web applications and APIs are frequently targeted by cybercriminals. To safeguard them, web application firewalls (WAFs) provide essential protection; they detect vulnerabilities while stopping data leakage from leaving the organization.

Imperva is an industry leader in both appliance and cloud WAF service offerings. Their SecuritySphere WAF product provides strong functionality and innovation while supporting multicloud strategies.


Web application firewalls (WAFs), unlike traditional network layer firewalls, analyze traffic at the application layer. This enables them to detect attacks not identifiable with traditional firewalls and block them immediately. WAFs can be implemented as hardware appliances, virtual appliances or cloud-based solutions and used to protect against cyber attacks like cross-site scripting (XSS), SQL injection and DDoS attacks.

An effective WAF can prevent unauthorite data from exiting web apps, offering businesses protection from security breaches and loss of customer information. When selecting one for business use it’s crucial that it provides both security and performance benefits in equal measures.

Gartner has named Imperva the leader of both its WAF appliance and service segments of their Magic Quadrant for WAFs. Imperva boasts strong user satisfaction ratings, offering advanced security features such as machine learning engines and bot mitigation capabilities – as well as being cost-effective solutions for businesses on tight budgets.


If you require a WAF that can support high volumes of traffic, look for one with scalability. One such solution is AppTrana Managed Web Application Firewall which offers cloud-based protection that scales with increased web traffic volumes without impacting performance, also including DDoS protection as part of its package and content delivery network capabilities – perfect for businesses that don’t wish to worry about managing servers themselves or setting security policies themselves.

NetScaler Web Application Firewall can also be integrated with full ADC features to offer high performance and scalable security capabilities, similar to F5 Essential App Protect for non-technical users. Based on F5 technology, this mature product uses blacklisting to stop hackers and whitelisting to let valid users into websites while also monitoring for data theft attempts – making it an excellent solution for organizations with numerous Web assets.


Web application firewalls (WAFs) are essential in protecting websites against cyber attacks. WAFs identify vulnerabilities and mitigate threats in real time while offering granular access control features and secure delivery. Furthermore, they give insight into traffic patterns for increased transparency.

Your WAF may come as software, an appliance or as a service and requires manual updates of its policies for optimal operation; other models use machine learning to identify and block emerging vulnerabilities automatically.

An advanced integration framework enables rapid CI/CD processes with third-party tools like Puppet, Chef, Ansible and Terraform. Our full-featured REST API connects these tools for blue-green deployments and canary rollouts as well as canary rollouts. Furthermore, you can tailor the UI to match your organization’s style to allow non-technical staff members to easily manage this platform.


Web application firewalls (WAFs) protect websites against SQL injection attacks, cross-site scripting attacks and other cyber threats such as DDoS attacks. WAFs also offer data theft prevention as well as threat intelligence capabilities to identify new vulnerabilities; making them essential components of any website security strategy. WAFs come both as cloud solutions or network appliances.

Some providers offer various deployment options, enabling customers to choose which option best meets their needs. Fortinet FortiWeb WAF can be deployed as either an appliance, virtual appliance, or SaaS system; other choices include Akamai Kona Site Defender which combines offsite WAF capabilities with DDoS protection.

The StackPath Web Application Firewall is a subscription-based cloud service that works by routing traffic through a server in the cloud, which then inspects incoming requests before blocking them before reaching your Web servers. This service can be especially beneficial for businesses with high levels of traffic or when combined with CDN technology for improved performance.
