What we assess
Objectives and boundaries
Target assets, permitted starting positions, roles and business questions.
Trust relationships
Application, API or infrastructure boundaries relevant to the objective.
Controlled validation
Minimal-impact proof of exploitability under documented limits.
Risk and recovery
Business impact, evidence handling, cleanup obligations and remediation priorities.
Who it is for
Security leaders and technical teams that need deeper validation of a specific threat path, critical application or connected environment.
Before we start
Define the objective, assets, access assumptions, prohibited techniques, testing windows and emergency contact. Third-party systems, social engineering and denial of service are not included without their own explicit authorization.
Methodology
From scope to verified fixes.
Use discovery to identify candidate paths, then validate prerequisites and attempt only the proof needed to answer the objective. PTES and relevant OWASP guidance inform the process; MITRE ATT&CK can help describe applicable behaviors. Findings distinguish demonstrated impact from plausible but untested consequences.
- Agree authorization, coverage, test limits and evidence handling.
- Discover and manually validate candidate weaknesses.
- Report confirmed findings, unverified observations and coverage limitations distinctly.
- Discuss remediation and retest the specified fixes within the agreed window.
Typical issues we look for
Examples of possible issues, not findings from R53SEC client engagements. Actual results depend on the system and scope.
- A low-privilege account can cross an intended role boundary and reach a sensitive function.
- A configuration weakness combines with service exposure to create a route to a protected asset.
- A proposed attack path is blocked by a control, providing a useful coverage observation rather than a fabricated vulnerability.
What you receive
An objective and coverage summary, evidenced attack paths, affected assets, severity rationale, technical reproduction, practical mitigations and an agreed retest plan.
The report includes an executive summary, finding identifiers, severity rationale, impact, evidence, remediation and coverage limitations. CVSS is included where appropriate with its version, vector and assumptions. Retest scope, timing and commercial terms are agreed before work begins.
Questions about Penetration Testing
Is exploitation always necessary?
No. Sufficient evidence may establish risk without a disruptive action. Safety limits and the agreed proof objective determine how far validation proceeds.
Can a penetration test guarantee there are no vulnerabilities?
No. It is a time- and scope-bounded assessment. The report explains access limits, exclusions and untested areas.
Is retesting included automatically?
Retest scope, window and commercial terms are agreed in the engagement. A retest validates specified fixes; it is not automatically a new full assessment.
