NowSecure Pentesting as a Service (PTaaS) is a mobile application security testing service that combines automated testing capabilities with manual penetration testing performed by security analysts. The service supports testing of mobile apps on iOS and Android platforms, as well as Over-the-Top (OTT) applications running on streaming platforms like Roku and Apple TV. It also covers web APIs, embedded apps, and third-party components. The platform provides continuous testing cycles that can be aligned with application risk profiles, allowing organizations to test high-risk applications more frequently while maintaining coverage across their entire mobile app portfolio. Testing includes forensic analysis of data artifacts on devices, network communications analysis (encrypted and unencrypted), binary resiliency assessment, hardcoded secrets investigation, API call analysis, and privacy exposure evaluation. Reports include detailed vulnerability descriptions, reproduction steps, remediation guidance, references to best practices, and mappings to compliance frameworks such as OWASP MASVS, NIAP, PCI DSS, HIPAA, and NIST. The service includes consultation with security analysts, report readouts, and retesting at no additional cost to validate remediation efforts. The platform integrates with CI/CD pipelines, issue tracking systems, and vulnerability management platforms through pre-built integrations, open APIs, and a native CLI. Organizations can request formal attestation letters to support regulatory compliance and customer assurance requirements.
