With the number of attempted web attacks ranging up to millions over the course a year, you need to ensure web application security. You need a solution that protects both your public and internal web properties.
Why you need a web application firewall
Today’s businesses strive to provide the highest possible service experience and engagement through different types of interactive web applications and user-friendly mobile applications. Over half of the world population uses the internet. Ninety three percent of them now go online, and perhaps stay online longer, using their mobile devices as opposed to their computers.
With the addition of the Internet-of-Things (IoT), we have now added tens of billions of devices already connected, communicating and exchanging data through web and mobile applications today — from TVs, digital wearables, cars, gaming consoles and vending units, to all sorts of smart appliances. This makes web applications more critical now than ever before. You need keep them all online and safe.
What makes a good web application firewall?
An ideal solution requires a comprehensive foundation for application security, data leak prevention, performance and management. With most web servers vulnerable to a wide spectrum of web-based exploits, you need a dynamic web application firewall to provide continuous real-time protection for web properties, whether they are hosted on-premises or in the public cloud. A best-practices WAF solution requires feature-rich web security tools and services to keep web properties safe, undisrupted and in peak performance every single day.
SonicWall Web Application Firewall
Our award-winning solutions give you a defense-in-depth strategy to protect your web applications running in private, public or hybrid cloud environments. It offers you a complete, out-of-box compliance solution for application-centric security that is easy to manage and deploy.
The SonicWall WAF series arms you with advanced web security tools and services to protect your data and web properties against modern, web-based threats. It applies deep packet inspection of Layer 7 web traffic against a regularly updated database of known signatures, denies access upon detecting web application threats and redirects users to an explanatory error page.
In addition, the SonicWall WAF baselines regular web application usage and behavior, and identifies anomalies that may be indicative of attempts to compromise the application, steal data and/or cause a denial of service (DoS).
SonicWall WAF employs a combination of signature-based and application profiling deep-packet inspection, and high-performance, real-time intrusion scanning engine, to dynamically defend against evolving threats, as outlined by the Open Web Application Security Project (OWASP), as well as more advanced web application threats like denial-of-service (DoS) attacks and context-aware exploits. Moreover, it learns, interrogates and baselines regular web application usage behaviors and identifies anomalies that may indicate attempts to compromise the application, steal data and/or cause a denial of service.
The WAF series gives you economy-of-scale benefits of virtualization. You can deploy it as a virtual appliance in private clouds based on VMWare or Microsoft Hyper-V; or in AWS or Microsoft Azure public cloud environments. This gives you all the security advantages of a physical WAF with the operational and economic benefits of virtualization, including system scalability and agility, speed of system provisioning, simple management and cost reduction.
Acceleration features include load balancing, content caching, compression and connection multiplexing to improve performance of protected websites, and significantly reduce transactional costs. A robust dashboard gives you an easy-to-use, web-based management interface featuring status page overview of all monitoring and blocking activities, such as signature database status information and threats detected and prevented since boot-up.
The is available in four models that represent their inspection capacities and can be deployed on a broad range of public cloud, private cloud and virtualized deployment use cases.
