Penetration test costs range from $4,000 to $150,000+ depending on scope, company size, compliance requirements, and timeline. A basic web application pen test for a small SaaS company typically runs $5,000–$15,000. A full-scope red team engagement for a large enterprise can exceed $100,000.

A vulnerability scan is an automated tool that identifies known weaknesses against a CVE database — it finds what might be vulnerable. A penetration test is a manual, adversarial assessment where skilled testers attempt to actually exploit vulnerabilities, chain weaknesses together, and demonstrate the real-world business impact of a successful attack. Vulnerability scans produce lists; penetration tests produce proof-of-exploitation with business context.

Most security frameworks (SOC 2, ISO 27001, PCI DSS) require penetration testing at least annually. In practice, organizations should test after any significant infrastructure or application change, when entering new compliance regimes, after a security incident, and before major product launches. High-risk environments (financial services, healthcare) typically test twice yearly at minimum.

In a black-box test, testers start with no prior knowledge — simulating an external attacker. In a grey-box test, testers are given limited information such as user credentials or network diagrams — simulating a compromised insider or a vendor with partial access. In a white-box test, testers have full access to source code, architecture documents, and credentials — maximizing coverage and efficiency. Grey-box is the most common approach for web application testing; black-box is most common for red team engagements.

A focused web application pen test typically takes 3–5 business days of active testing plus 2–3 days for reporting. A network penetration test for a medium-sized environment runs 5–10 business days. A red team engagement can span 3–6 weeks. Compliance-accelerated timelines are available — BugFoe offers rush delivery for organizations facing imminent audits.

A quality pen test report includes an executive summary written for non-technical stakeholders (risk posture, key findings, business impact), a technical findings section with proof-of-exploitation screenshots, CVSS scores, and step-by-step reproduction steps, and a remediation roadmap prioritized by risk. BugFoe also includes a re-test of critical and high findings to verify remediation, at no additional cost.
