ImmuniWeb® On-Demand is a web application penetration testing platform that combines machine learning technology with manual security testing conducted by CREST-accredited penetration testers. The platform provides comprehensive web application security assessments that cover OWASP Top 10, OWASP Top 10 API, SANS Top 25, and PCI DSS 6.2.4 requirements. Testing includes both automated vulnerability scanning and manual penetration testing with business logic analysis. Key features include authenticated testing with multi-factor authentication and single sign-on support, REST/SOAP/GraphQL API security testing, and cloud-specific vulnerability assessment for applications hosted on AWS, Azure, and GCP. The platform can test both internal and external web applications using virtual appliance technology. The service offers multiple testing packages ranging from Express Pro (1 day manual testing) to Ultimate (10 days with threat-led penetration testing). All packages include unlimited patch verification assessments within 100 days of report delivery. Reports are generated in multiple formats (web, PDF, JSON, XML, CSV) and include MITRE ATT&CK matrix mapping, CVE/CWE compatibility, CVSS v4 scoring, and compliance sections for PCI DSS and GDPR. The platform provides zero false-positives guarantee and rapid delivery service level agreements. Integration capabilities include DevSecOps tools like Jira, GitHub, GitLab, Splunk, and web application firewall (WAF) virtual patching for F5, Imperva, Barracuda, Fortinet, and Qualys systems. The platform supports continuous integration/continuous deployment (CI/CD) workflows and provides 24/7 access to security analysts.
