HackerOne Pentest is a Pentest as a Service (PTaaS) platform that connects organizations to a vetted pool of elite pentesters for security testing. The service supports testing across web applications, APIs, networks, mobile apps, cloud infrastructure, AI/LLMs, desktop applications, and source code. The platform delivers real-time findings through a centralized dashboard, enabling organizations to track vulnerabilities as they are discovered and begin remediation during active testing. Pentesters are matched to specific asset types and technology stacks, with testing aligned to industry standards and real-world attack scenarios. HackerOne Agentic PTaaS extends the traditional model by incorporating AI agents that assist with reconnaissance, setup, exploitation, and validation under human oversight. All agent findings are reviewed and validated by expert pentesters to ensure quality and accuracy. The service includes a Pentest Scoping Assistant to help define test parameters, real-time collaboration capabilities, retesting to validate fixes, and comprehensive final reports. Reports support compliance requirements for standards including SOC 2, ISO 27001, GDPR, PCI DSS, HIPAA, and others. Testing methodologies cover OWASP Top 10 risks, cloud misconfigurations, prompt injection for LLMs, mobile security analysis, API business logic flaws, network scanning, and source code review for logic flaws and insecure patterns.
