What We Solve

Reveal real risk and deliver a fixable path to higher security.

We review desktop clients, mobile apps, services, binaries, APIs, AI workflows, and operational assumptions together instead of pretending each layer can be secured in isolation. We expose weak boundaries, broken auth flows, unsafe defaults, vulnerable dependencies, runtime blind spots, and trust assumptions that collapse once a real attacker moves across systems.

That usually shows up as desktop client risk in local storage, update paths, IPC, plugins, and native trust assumptions, mobile and device exposure in token handling, deep links, transport security, and client-to-API boundaries, backend and API weaknesses in authorization, identity flows, and privileged paths, and embedded or binary risk when source is partial, outdated, or unavailable.

What You Get

  • Attack surface map across desktop, mobile, API, AI, and device-facing layers
  • Prioritized findings with exploit narrative, impact, and evidence
  • Remediation plan aligned with architecture and delivery reality
  • Proof of fixes through retesting and regression checks
  • Buyer-ready security evidence leadership, engineering, and procurement can actually use

Coverage and Methods

Audit Surface

  • Desktop software, native clients, and local trust assumptions
  • Mobile apps, device trust, and client-to-API boundaries
  • APIs, services, identity flows, and tenant separation
  • AI features, agents, data boundaries, and tool permissions

Targets

  • Cloud, on-prem, hybrid, edge
  • Desktop, mobile, web, and embedded-adjacent systems
  • Binaries when source is partial or missing
  • Critical auth, session, data, and integration paths

Techniques

  • Threat modeling and attack path analysis
  • Source and binary review with static and dynamic analysis
  • Runtime validation, interception, instrumentation, and fuzzing plans
  • Privilege mapping, trust-boundary review, and exploitability testing

Outputs

  • Findings with evidence, reproduction notes, and priority order
  • Fix guidance with tradeoffs that match delivery reality
  • Retesting and closure validation
  • Leadership summary for release, diligence, or buyer review
