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. You receive ongoing assurance through continuous testing, monitoring, incident response, change management, and detailed reporting. Our fully managed model significantly reduces your total cost of ownership while enabling stronger and faster risk mitigation.
