RedShield offers a comprehensive managed web application and API security service. Our expert team provides real-time vulnerability remediation as a fully managed service, with no application code changes required. WEB-APPLICATION & API SECURITY: RedShield delivers advanced protection and proactive remediation for web applications and APIs. By seamlessly routing your web traffic through our AWS-powered platform, we apply real-time fixes, referred to as “in-flight patches,” to neutralize vulnerabilities in applications as they are detected. These patches work alongside complementary Web Application Firewall (WAF) and DDoS/bot protection, and our service continuously monitors and mitigates attacks to provide risk reduction for customers. NO APPLICATION CODE CHANGES NEEDED: Our solution operates without requiring any changes to your application code. Once traffic is routed through our platform, vulnerability scans and pen-test results are analysed by our global security experts. Fixes are then automatically deployed. For unique or complex vulnerabilities, including business logic issues, our 24/7 defense teams design custom in-flight security patches to fix the vulnerabilities on-the-wire. ASSURED OUTCOMES: RedShield is more than just a tool. It is a service with guaranteed security outcomes.
