About NowSecure

NowSecure sells mobile application risk management software that analyzes compiled iOS and Android app binaries on real devices to find hidden AI, risky SDKs, vulnerabilities and data flows. NowSecure says it helps organizations secure and govern mobile app risk, from code and dependencies to runtime behavior and data flows.

NowSecure says more than half of the 50,000+ mobile apps it analyzes each month contain undisclosed AI. NowSecure says most AI governance programs cover SaaS, cloud, and employee AI tools. NowSecure says it builds the mobile app record those programs are missing: which apps contain AI, what data it touches, where that data goes, and who owns the risk.

NowSecure analyzes the shipped mobile binary to identify AI models, SDKs, dependencies, APIs, and indicators of AI-generated code. NowSecure runs the app on real devices to observe live behavior, permissions, connections, and data movement. NowSecure says the result is a Dynamic SBOM showing every component and where its data lands. NowSecure says it fills the gap with binary and runtime truth, not source, SBOM, or SCA assumptions.

Mobile Application Risk Management brings four risk domains into one operating model. NowSecure says Mobile Application Risk Management exists to close visibility gaps before they become business events. NowSecure gives enterprises continuous, evidence-based visibility into the security, privacy, compliance, and AI risk inside the mobile apps they build, use, and manage. NowSecure says the new shape of mobile app risk management is continuous, evidence-based, and proportioned to business impact, governing security, privacy, safety, compliance, and AI risk in one program. NowSecure describes a living catalog of apps, SDKs, APIs, AI components, data destinations, and ownership across the mobile estate. NowSecure says it gives every accountable function the evidence to find hidden AI, govern data flows, and reduce risk across the apps an organization builds and uses.[5]

NowSecure tests the compiled iOS and Android app on real devices, logged in, with every SDK and AI feature inside it. NowSecure says AI-Navigator logs in so dynamic testing reaches every post-login screen. NowSecure research found that authenticated mobile app security testing finds 78% more sensitive data risk. Customers can upload an IPA or APK, or trigger tests automatically from GitHub Actions, GitLab, Azure DevOps, Jenkins, CircleCI, or Bitrise. NowSecure maps findings to OWASP MASVS and sends them to the customer's tracker with remediation guidance. NowSecure adds Guided Testing or Pen Testing as a Service when an app needs an analyst to work through MFA. NowSecure identifies every component inside the compiled app and watches what each one does at runtime. NowSecure identifies the AI inside an app and shows what data reaches it.[5][6]

NowSecure inspects compiled iOS, Android, and hybrid apps to identify every dependency, framework, and SDK actually present. NowSecure generates SBOMs for each build, storing version history and provenance. A signed, machine-readable SBOM in CycloneDX or SPDX is generated and versioned. NowSecure produces SBOMs automatically at each merge or release, within GitHub Actions, GitLab, Jenkins, and Azure DevOps. NowSecure correlates SBOM data with live CVE, CWE, and license feeds for immediate risk visibility. NowSecure says organizations using Dynamic Mobile SBOM transition from reactive audits to proactive risk governance.[7]

NowSecure Privacy protects sensitive data, minimizes compliance exposure, and maintains trust. NowSecure tests for the OWASP MASVS throughout the mobile app security testing software and services. NowSecure supports organizations looking to comply with ISO 27001 by implementing mobile app security controls. NowSecure says it helps write the mobile security standards auditors rely on and maintains the open-source tools that power runtime analysis worldwide. Carlos Holguera, a NowSecure principal research engineer, co-leads the OWASP Mobile Application Security project that maintains MASVS and MASTG.[6][8][9]

For mobile banking apps, NowSecure says new regulatory standards demand a real-time Mobile App BOM and continuous runtime validation. NowSecure says financial institutions are fully accountable for every component shipped to production, including software their internal engineers never wrote. NowSecure says it generates an audit-ready Mobile Application Bill of Materials through automated binary analysis on every build. NowSecure helps federal, local and state agencies, including AirForce’s BESPIN software factory, deliver secure mobile apps. NowSecure Platform performs static, dynamic, interactive and API security analysis across the mobile apps in an organization's environment.[2][10][11]

NowSecure cites NIAP, ISO 17025, and Google MASA lab credentials. Independent auditor Coalfire completed its review of NowSecure and issued an attestation report finding zero deficiencies. NowSecure provides a SOC 2 report to requesters who first execute an NDA.[6][8][12]
