Methodology

A disciplined model for offensive security testing.

Our methodology is designed to identify realistic attack paths, validate exploitable risk, and turn technical findings into remediation decisions.

Discuss scope

Beyond scanner output

Automation helps coverage. Human validation determines risk.

Tessen Security uses automation where it improves coverage and repeatability, but the engagement does not stop at tool output. Findings are reviewed, reproduced, connected to context, and prioritized by real-world exploitability.

Engagement flow

How the work progresses.

  1. 01

    Scope definition

    We align on systems, roles, environments, constraints, and authorization before testing begins.

    • Assets
    • Rules of engagement
    • Access model
  2. 02

    Context review

    We study architecture, exposed workflows, business functions, and known security assumptions.

    • Architecture
    • Data flows
    • Threat context
  3. 03

    Reconnaissance

    We map reachable surfaces and observable behavior to understand likely entry points.

    • Attack surface
    • Identity boundaries
    • Public exposure
  4. 04

    Manual testing

    We test authentication, authorization, application logic, APIs, configurations, and workflow abuse paths.

    • Business logic
    • Access control
    • API behavior
  5. 05

    Exploitability validation

    We validate whether a weakness can be reproduced and what access, data, or control it creates.

    • Reproduction
    • Impact
    • Constraints
  6. 06

    Risk prioritization

    We rank findings by exploitability, business impact, exposure, and remediation urgency.

    • Severity
    • Exposure
    • Business impact
  7. 07

    Reporting

    We document evidence, affected assets, reproduction details, remediation guidance, and decision context.

    • Evidence
    • Remediation
    • Decision support
  8. 08

    Readout

    We walk technical and business stakeholders through the findings that require attention.

    • Executive summary
    • Technical review
    • Next actions
  9. 09

    Retesting

    We validate remediation where included in scope and clarify any residual risk.

    • Fix validation
    • Residual risk
    • Closure

Tooling

Automation is a support system, not the conclusion.

Automated coverage can reveal useful leads, but severity is only useful when it is tied to validated behavior. Tessen Security’s methodology keeps human judgment responsible for prioritization.

  • Scanner findings are verified before they become reportable issues.
  • Manual testing focuses on logic, authorization, chained impact, and context.
  • Outputs distinguish exploitable risk from informational noise.

Deliverables

What teams receive.

  • Executive risk summary
  • Validated technical findings
  • Reproduction evidence
  • Severity rationale
  • Remediation guidance
  • Affected asset context
  • Prioritized remediation sequence
  • Retest notes where applicable
