Offensive security

Manual testing built around the decision you need to make.

Every engagement starts with written authorization, target boundaries, roles, production constraints, and the outcome the work must support. The report is evidence, not a scanner queue.

Based in Blaine, Minnesota, with local and remote work within agreed scope.

Scope a security review Prepare for an assessment

Architecture before payloads

Trace the boundary, not the checklist.Applications, identities, APIs, and infrastructure are examined as connected surfaces. The route matters because impact rarely stays inside one box.

Applications / APIs

Web Application & API Penetration Testing

Manual testing of the paths that can produce unauthorized access, data exposure, account compromise, or business-process abuse.

A report that separates reproducible security failures from scanner output and gives developers evidence they can act on.Review scope and deliverables

Android / iOS

Mobile Application Security Testing

Android and iOS testing that treats the client, APIs, identity systems, and connected workflows as one attack surface.

Clear evidence of what the application trusts, what the backend enforces, and whether a modified client can reach hidden behavior.Review scope and deliverables

External surface / cloud

Network & Cloud Security Review

A focused review of what the public internet can reach and how identity, service, and configuration issues could form an attack path.

An evidence-based view of reachable assets, verified findings, ownership gaps, and prioritized remediation.Review scope and deliverables

Retest / closure

Remediation Verification

Focused retesting that answers whether a fix removed the reported risk without leaving a bypass or adjacent workflow exposed.

A plain closure status: fixed, partially fixed, still vulnerable, not reproducible, or replaced by a related issue, with supporting evidence.Review scope and deliverables

Ongoing judgment

Security Advisory Retainer

Direct access to offensive-security judgment for small businesses, agencies, startups, and lean engineering teams.

Continuity across recurring decisions without pretending a limited retainer replaces a SOC, legal counsel, compliance, or unrestricted incident response.Review scope and deliverables

Every engagement

Clear boundaries in. Actionable evidence out.

Written scope, authorization, exclusions, communication rules, and testing constraints
Manual testing supported by reconnaissance and source review when access allows
Findings with evidence, affected roles/assets, demonstrated impact, and remediation
An executive summary that preserves the technical detail developers need
Focused remediation review or retesting when included in the engagement
