Summary
Learn the five essential questions to ask before choosing a penetration-testing vendor. Understand how methodology, reporting quality, CREST certification, and regulatory alignment affect your security posture and business resilience. Ideal for NIS2 and DORA-regulated organisations.
Introduction
Penetration testing is not just a technical exercise, it is a strategic investment that directly influences operational resilience, regulatory obligations, and an organisation’s wider risk posture. Despite this, many businesses are still presented with little more than automated vulnerability-scan outputs marketed as full penetration tests.
A meaningful penetration test goes far beyond tool output. It mirrors an adversary’s mindset, applying automation where appropriate but relying primarily on skilled human analysis to identify impactful vulnerabilities, validate them, and translate the results into clear, actionable guidance for both technical teams and executive stakeholders.
Selecting the right penetration-testing provider is therefore critical. A poor choice increases exposure, misallocates budget, and can leave compliance requirements unmet. The following questions help organisations distinguish between vendors who deliver genuine security assurance and those offering superficial testing.
The Motive
Boards, CISOs, and IT leaders increasingly require independent assurance that their systems are resilient, defensible, and aligned with broader business objectives.
With regulations such as the NIS2 Directive and the Digital Operational Resilience Act (DORA), penetration testing has become a core element of organisational risk management and compliance. These frameworks expect organisations not only to identify weaknesses, but to demonstrate that they have been proactively assessed and remediated.
At CommSec, our purpose is straightforward: transform unknown vulnerabilities into actionable insight. Our testing approach strengthens operational resilience, enhances audit and regulatory readiness, and provides the confidence that your organisation is prepared for real-world threats.
The Pain
Many organisations invest in penetration testing yet receive outputs that fall short of what meaningful assurance should look like. Reports are often generic, superficial, or disconnected from real business risk.
As one IT leader put it on Reddit:
“Each pen test is a dice roll… sometimes we get good testers, sometimes we don’t.”
This inconsistency creates blind spots. When a vendor delivers little more than scanning, with minimal exploitation and no analysis of business impact, the results cannot support informed decision-making.
CommSec’s approach is different. Our testers think and operate like adversaries. We validate whether vulnerabilities can be exploited, assess the potential business impact, and provide clear remediation guidance. This delivers assurance that goes far beyond automated assessments and ensures that findings carry real operational value.
What to Ask
Before choosing a penetration-testing partner, organisations should ask five key questions. These questions separate genuine expertise from superficial testing and ensure that any investment in penetration testing contributes meaningfully to both security posture and broader business objectives.
Can you provide a sample report?
A reputable vendor should be able to share a fully redacted sample report that illustrates the quality, clarity, and depth of their deliverables. This allows you to assess whether their reporting aligns with your expectations and supports both technical teams and executive stakeholders.
A high-quality report typically includes:
• a concise executive summary for business leaders
• validated and risk-rated findings
• evidence of exploitation where appropriate
• prioritised, actionable remediation guidance
• references to regulatory or compliance obligations
At CommSec, our reports clearly demonstrate business impact, outline practical remediation steps, and provide leadership with the direction needed to strengthen security posture.
What are the tester credentials and track record?
Penetration testing quality depends entirely on the skill of the testers. Certifications such as CREST, OSCP, GWAPT, CISSP, and CEH demonstrate the level of expertise required to identify complex weaknesses.
CREST accreditation aligns with major industry frameworks:
• DORA: requires threat-led penetration testing by CREST-certified providers.
• PCI DSS: mandates penetration testing; CREST helps satisfy auditor expectations.
• ISO 27001: considers penetration testing best practice for demonstrating control effectiveness.
• Cyber Essentials Plus: requires accredited, independent testing.
CommSec’s penetration-testing team includes CREST-certified and OSCP-qualified testers with deep experience across enterprise, cloud, and application environments.
What is your methodology and how do you design scope?
Different environments demand different testing approaches, and a credible vendor should clearly explain their methodology and how it aligns with your business objectives.
A well-defined methodology addresses factors such as:
• whether the engagement is black-box, grey-box, or white-box
• coverage of web applications, APIs, cloud platforms, internal networks, mobile apps, and identity systems
• inclusion of social engineering where appropriate
• alignment with business priorities, operational constraints, and regulatory obligations
At CommSec, we follow a structured six-phase methodology that provides consistency, depth, and traceability:
- Scoping and objective definition
- Intelligence gathering
- Vulnerability analysis
- Exploitation
- Post-exploitation
- Reporting and remediation support
Our methodology aligns with established frameworks such as OWASP, NIST, and MITRE ATT&CK, ensuring that testing is repeatable, evidence-driven, and tailored to your organisation’s risk profile.
How do you handle scope changes or unexpected findings?
Complex environments often reveal new risks during testing. A mature vendor should be able to explain how they manage these situations — including how scope changes are assessed, how timelines or effort may be adjusted, and how this is communicated to stakeholders.
A clear process prevents gaps in coverage and ensures the engagement remains aligned with operational needs, risk priorities, and budget expectations.
How will findings be validated and integrated into our cyber-security lifecycle?
A penetration test only creates value when findings are remediated and incorporated into your ongoing security operations.
Ask your vendor how they support:
- retesting
- remediation guidance
- alignment with SOC or MDR workflows
- compliance mapping
- operational risk reduction
CommSec positions penetration testing as part of your broader security-testing framework, ensuring that technical issues translate into business improvements.
At CommSec, communication is continuous and transparent. Any change in scope is discussed before action is taken, and there are no hidden steps or unexpected costs. Our goal is to maintain clarity and control throughout the entire engagement.
