Web Application Firewall (WAF) by StormWall is a cloud-based security tool designed to protect web applications from various attacks. It does not require separate infrastructure or software, eliminating associated costs. WAF provides reliable security for critical Internet resources by analyzing web applications to detect and mitigate attacks. It protects critical web applications with complex business logic, including online stores, information resources, B2B platforms, remote customer service systems, corporate portals, state systems of interdepartmental interaction, and technological production control systems (MES, SCADA/APCS). WAF safeguards web resources for both small companies and large organizations, ensuring guaranteed availability of protected web resources. It supports modern web application models (MVC, SOA, REST, API-centric) and ensures reliable 24/7 protection against web application attacks with minimum false positives.
