Penetration Testing Cost: What You Should Expect to Pay in 2026

Posted: March 6, 2026 to Cybersecurity.

How Much Does Penetration Testing Cost?

Penetration testing costs typically range from $3,000 to $100,000 or more, depending on the scope, complexity, and type of testing required. For a small to mid-sized business with a straightforward network, a basic external penetration test usually costs between $3,000 and $15,000. A comprehensive engagement that includes external, internal, wireless, social engineering, and web application testing for a mid-sized organization can range from $15,000 to $50,000. Large enterprises with complex, multi-site environments can expect costs upward of $50,000 to $100,000 for thorough testing.

Understanding what drives penetration testing costs helps you budget appropriately, evaluate proposals from vendors, and ensure you are getting genuine value rather than paying for a glorified vulnerability scan that is mislabeled as a penetration test. The cost differences between providers are significant, and the cheapest option is rarely the best value.

Factors That Determine Penetration Testing Cost

Scope and Size of the Environment

The most significant cost driver is the size and complexity of the systems being tested. Key scope factors include:

• Number of IP addresses: External tests are often scoped by the number of external IP addresses or CIDR ranges. More IPs require more scanning and manual testing time.
• Number of internal hosts: Internal tests scale with the number of servers, workstations, network devices, and other systems on the internal network.
• Number of web applications: Each web application requires dedicated testing. A complex web application with dozens of dynamic pages, API endpoints, and user roles can take 3 to 5 days to test thoroughly.
• Number of locations: Multi-site organizations may require testing at each location, especially if networks are segmented differently across sites.
• Wireless networks: Testing wireless networks adds scope, particularly if multiple SSIDs, locations, or wireless technologies are in use.

Type of Penetration Test

Different types of testing carry different cost implications:

External network penetration test ($3,000 - $15,000): Tests your internet-facing systems and defenses from an outside attacker's perspective. This is the most common starting point and the most affordable type of penetration test.

Internal network penetration test ($5,000 - $20,000): Simulates an attacker who has already gained access to your internal network, whether through a compromised employee account, a malicious insider, or a breached perimeter. Internal testing typically reveals more critical findings than external testing because internal networks are often less hardened.

Web application penetration test ($5,000 - $25,000 per application): Focused testing of web applications for vulnerabilities including SQL injection, cross-site scripting, authentication bypass, authorization flaws, business logic errors, and API security issues. Complex applications with many features and user roles cost more to test.

Wireless penetration test ($3,000 - $10,000): Tests the security of your wireless networks including encryption strength, authentication mechanisms, rogue access point detection, and client-side attacks.

Social engineering test ($3,000 - $15,000): Tests your human defenses through phishing campaigns, pretexting phone calls, physical intrusion attempts, and other social engineering techniques. This type of testing evaluates the effectiveness of your security awareness training.

Red team engagement ($20,000 - $100,000+): A comprehensive, adversary-simulation exercise where the testing team uses any and all techniques to achieve specific objectives, such as accessing sensitive data, compromising critical systems, or moving laterally through the environment. Red team engagements simulate realistic attacks over extended periods and test your detection and response capabilities as well as your preventive controls.

Testing Methodology and Depth

The depth of testing significantly affects cost:

Automated scan with limited manual validation ($1,000 - $5,000): This is not a true penetration test. It is a vulnerability assessment with minimal manual follow-up. While it identifies known vulnerabilities, it misses business logic flaws, chained exploits, and novel attack paths. Be cautious of providers offering penetration testing at this price point because they are likely delivering vulnerability scans.

Standard manual penetration test ($5,000 - $25,000): Combines automated scanning with extensive manual testing by experienced penetration testers. Manual testing uncovers vulnerabilities that scanners miss and validates that identified vulnerabilities are actually exploitable.

Advanced manual testing with exploit development ($15,000 - $50,000+): The tester goes beyond known vulnerabilities to discover novel attack paths, develop custom exploits, chain multiple vulnerabilities together, and simulate advanced persistent threat techniques.

Tester Qualifications and Firm Reputation

The experience and certifications of the testing team affect pricing. Firms staffed with testers holding OSCP, OSCE, GPEN, GXPN, or CREST certifications command higher rates because these certifications validate hands-on exploitation skills. A penetration test conducted by a senior tester with 10 or more years of experience will cost more than one conducted by a junior tester, but it will also find more vulnerabilities and provide more actionable remediation guidance.

Compliance Requirements

If your penetration test must meet specific compliance requirements, additional costs may apply:

• HIPAA: Testing must evaluate controls specific to PHI protection
• PCI DSS: Requires testing by a PCI-qualified security assessor using specific methodology
• CMMC: Testing must validate controls from NIST SP 800-171
• SOC 2: Testing results feed into the SOC 2 audit process

Penetration Testing Cost Breakdown by Business Size

Here are typical cost ranges for common business profiles in the Raleigh, NC area:

Small business (10-25 employees, single location, 1 web app):

• External penetration test: $3,000 - $6,000
• Internal penetration test: $5,000 - $8,000
• Combined external + internal: $7,000 - $12,000

Mid-sized business (50-100 employees, 2-3 locations, multiple web apps):

• External penetration test: $8,000 - $15,000
• Internal penetration test: $10,000 - $20,000
• Comprehensive engagement (external + internal + web apps): $20,000 - $40,000

Larger organization (200+ employees, multiple locations, complex environment):

• Comprehensive penetration test: $30,000 - $75,000
• Red team engagement: $50,000 - $100,000+

How Often Should You Conduct Penetration Testing?

Most compliance frameworks and industry best practices recommend penetration testing at least annually, with additional testing after:

• Significant changes to your network infrastructure or applications
• Deployment of new internet-facing systems
• Major software updates or migrations
• After a security incident
• Before a compliance audit

Organizations in high-risk industries or those handling sensitive data should consider semi-annual or quarterly testing. Between full penetration tests, regular vulnerability assessments provide ongoing visibility into new vulnerabilities as they emerge.

How to Evaluate Penetration Testing Proposals

When comparing proposals from multiple vendors, look beyond price:

• Methodology: Ask for details on their testing approach. A credible firm will reference OWASP, PTES, or NIST SP 800-115.
• Team qualifications: Request the certifications and experience levels of the testers who will actually perform the work.
• Deliverables: Expect a detailed technical report with findings, risk ratings, evidence (screenshots, proof-of-concept), and specific remediation recommendations, plus an executive summary for leadership.
• Manual vs. automated: Ask what percentage of the engagement involves manual testing vs. automated scanning.
• Retest included: Quality providers include a free retest period (typically 30 to 90 days) so you can verify that remediated vulnerabilities are actually fixed.
• Insurance: Verify the firm carries professional liability and cyber liability insurance.
