Penetration testing costs between $5,000 and $110,000+ depending on what you're testing, how complex your environment is, and how deep you need the assessment to go. That's a wide range, and for good reason: a basic external scan of 50 IPs is a fundamentally different engagement than a full red team exercise across a multi-cloud enterprise with 200 applications.
This guide breaks down real-world pen test pricing by type, the factors that move the needle on cost, and how to maximize the value of every dollar you spend. If you're building a cybersecurity budget or evaluating vendor proposals, these numbers will help you set realistic expectations.
Penetration Testing Cost by Type
The type of penetration testing is the single biggest factor in pricing. Each targets a different attack surface and requires different expertise and time investment.
| Testing Type | Typical Cost Range | Duration | Best For |
|---|---|---|---|
| External Network | $5,000 - $20,000 | 5-10 days | Internet-facing infrastructure |
| Internal Network | $8,000 - $25,000 | 5-15 days | Insider threat, lateral movement |
| Web Application | $8,000 - $35,000 | 7-14 days | SaaS platforms, customer portals |
| API Testing | $6,000 - $25,000 | 5-10 days | REST/GraphQL APIs, microservices |
| Wireless | $5,000 - $15,000 | 3-5 days | Office WiFi, guest networks |
| Social Engineering | $5,000 - $20,000 | 5-10 days | Phishing, vishing, pretexting |
| Physical Security | $10,000 - $30,000 | 3-7 days | Data centers, offices, facilities |
| Red Team Assessment | $30,000 - $110,000+ | 2-6 weeks | Full adversary simulation |
| Cloud (AWS/Azure/GCP) | $10,000 - $40,000 | 5-15 days | Cloud configuration, IAM, containers |
Most mid-market companies spend $15,000-$40,000 annually on pen testing, typically combining an external/internal network test with web application testing for their most critical apps. Enterprise organizations with complex environments commonly invest $75,000-$150,000+ per year across multiple testing engagements.
6 Factors That Drive Penetration Testing Costs
1. Scope and Size of the Environment
The number of IP addresses, applications, locations, and user roles directly impacts tester hours. A network pen test covering 50 external IPs requires significantly less time than one covering 500+ IPs across three data centers. For web applications, complexity scales with the number of user roles, API endpoints, and integrations.
Cost impact: Each additional IP range or application can add $2,000-$8,000 to the engagement depending on complexity.
2. Testing Methodology (Black Box vs White Box)
Testing approach affects both duration and depth. In a black box engagement, the tester has no prior knowledge and simulates an external attacker, requiring more reconnaissance time but giving you a realistic view of your external posture. Gray box testing provides limited information like network diagrams and user credentials, balancing realism with depth; this is the most common approach for internal testing. White box gives the tester full access to source code, architecture docs, and credentials, maximizing vulnerability discovery at the cost of more tester hours.
Cost impact: White box testing typically costs 20-40% more than black box for the same scope because the tester analyzes more thoroughly with available documentation.
3. Industry and Compliance Requirements
Compliance-driven pen tests often have specific requirements that affect scope and methodology. PCI DSS pen tests must follow defined testing procedures and cover the entire cardholder data environment. HIPAA assessments need to address specific technical safeguards. These requirements can add documentation and testing time.
Cost impact: Compliance-specific testing adds 10-25% to baseline costs due to additional documentation, methodology requirements, and attestation reporting.
4. Remediation Retesting
A thorough pen test engagement should include a retest period where the vendor validates that critical and high-severity findings have been properly remediated. Some vendors include one retest; others charge separately.
Cost impact: Retesting typically runs $2,000-$5,000 or 10-15% of the original engagement cost. Always confirm what's included before signing a statement of work.
5. Tester Experience and Certifications
An OSCP or GPEN-certified tester with 10 years of experience charges more per hour than a junior tester running automated tools. The difference shows in findings quality: experienced testers discover business logic flaws, complex attack chains, and post-exploitation paths that tools and junior testers miss entirely.
Cost impact: Firms staffed with senior certified testers charge 30-60% premiums, but the findings are significantly more actionable.
6. Reporting Depth and Deliverables
A pen test is only as valuable as the report it produces. Quality reports include executive summaries for leadership, detailed technical findings with proof-of-concept evidence, risk ratings, remediation guidance with specific steps, and strategic recommendations.
Cost impact: Vendors offering detailed reports with executive summaries, technical walkthroughs, and strategic recommendations typically charge $2,000-$5,000 more than those delivering basic vulnerability lists.
