How to select the most suitable penetration testing provider for my organization
When opting for a penetration testing provider, first identify your preferred form of assistance. Determine if you require automated scanning, manual testing, or both. Compile a list of all targets, applications, and types of assets that necessitate evaluation. Consider the frequency of pentesting you desire: Are you seeking a one-time assessment or continuous monitoring of your entire infrastructure?

Once you establish these criteria, approach your preferred options to gather pricing estimates. Many pentesting providers adopt a quote-based pricing model due to the unique nature of each engagement. Their sales team engages in comprehensive discussions with you regarding your requirements and budget to formulate a tailored quote. Additionally, some providers may offer a trial or demo of their vulnerability scanning tools.
After evaluating your top choices and receiving quotes, finalize your selection of the best penetration testing provider for your organization. If undecided, consider engaging in a scope-limited project with the company for a brief period to observe their functionality before committing to an annual contract immediately.
Approach
To identify the top penetration testing providers, I reviewed service documentation and client feedback. Throughout this assessment, I evaluated aspects like pentest capacity, compliance adherence, and expert remediation services. Additional considerations included pricing structure, customer support quality, and turnaround time.
