question: "What is the best pentesting tool?"
title: "What Is the Best Pentesting Tool"
seoTitle: "Best Penetration Testing Tools and Services"
summary: "The best pentesting tool depends on what you actually need. If you are buying a penetration test for SOC 2 or a customer contract, you need a human-led engagement, typically $4,000 to $30,000 depending on scope, not a tool. Among the tools testers themselves use, Burp Suite is the standard for web application testing, Nmap for network discovery, Metasploit for exploitation, and OWASP ZAP is the leading free alternative for web scanning. Pentest-as-a-service platforms like Cobalt and HackerOne sit between the two, selling human testing through a software platform. Running an automated scanner is not a penetration test, and auditors and enterprise buyers know the difference."

faqs:
  - question: "Does SOC 2 require a penetration test?"
    answer: "No, SOC 2 does not strictly require one. The Trust Services Criteria ask you to evaluate and test your controls, and a pentest is one accepted way to do that, but many SOC 2 reports are issued without one. In practice enterprise customers usually demand a recent pentest report in security reviews regardless of what SOC 2 requires, so most companies pursuing SOC 2 end up commissioning one anyway."
  - question: "How much does a penetration test cost?"
    answer: "A credible human-led penetration test typically costs $4,000 to $30,000 depending on scope. A focused web application test for a small SaaS product sits at the low end; testing multiple applications, APIs, cloud infrastructure, and internal networks pushes toward the high end. Quotes far below that range usually mean an automated scan with a report template, which will not satisfy an enterprise security review."
  - question: "Is Burp Suite free?"
    answer: "Partly. Burp Suite Community Edition is free and includes the core proxy and manual testing tools, which is enough to learn on. Burp Suite Professional, which adds the active scanner, intruder automation, and extensions most professional testers rely on, is a paid annual per-user license."
  - question: "What is the ISO standard for penetration testing?"
    answer: "There is no ISO standard that mandates or defines penetration testing specifically. ISO 27001 Annex A expects technical vulnerability management, and a pentest is one accepted way to meet that, but the standard does not require one by name. The methodology references testers actually cite are the OWASP testing guides, PTES (the Penetration Testing Execution Standard), and NIST SP 800-115."
  - question: "How long does a penetration test take?"
    answer: "A typical web application engagement runs 1 to 3 weeks of active testing, followed by several days for reporting. Scope drives the number: a single application with a handful of user roles sits at the short end, while multiple applications, APIs, and cloud infrastructure extend it. Add lead time too, since reputable firms often book 2 to 6 weeks out."

## What is the best pentesting tool?

If you are buying "a pentest" for SOC 2 or a customer contract, the answer is not a tool at all: you need a human-led engagement from a testing firm, typically $4,000 to $30,000 depending on scope. If you are asking which tools penetration testers use, Burp Suite is the standard for web applications, with Nmap, Metasploit, and OWASP ZAP covering the other phases of an engagement.

## A tool is not a pentest

The question hides an ambiguity worth resolving. A penetration test is a service: a person attempts to break into your systems, chains findings together, and writes a report a third party will accept. A pentesting tool is something that person uses. Companies that need to hand a customer or auditor a pentest report cannot substitute a tool, because the deliverable is the tester's judgment, and buyers check who performed the test.

Automated scanners are the common trap. A vulnerability scan finds known issues; a penetration test demonstrates what an attacker can do with them. Auditors and enterprise security reviewers know the difference, and a scan report labeled as a pentest tends to get rejected in exactly the reviews it was purchased for.

## The tools and services, by what they do

| Tool or service | What it is for | Cost model |
|---|---|---|
| Burp Suite | Web application testing; the industry-standard intercepting proxy and scanner | Free Community Edition; paid Professional license |
| Nmap | Network discovery and port scanning; the first step of most engagements | Free, open source |
| Metasploit | Exploitation framework for validating that vulnerabilities are actually exploitable | Open source framework; commercial Pro edition |
| OWASP ZAP | Free web application scanner; the main open source alternative to Burp | Free, open source |
| Cobalt | Pentest as a service: human testers delivered through a platform | Commercial, per-engagement or subscription |
| HackerOne | PTaaS and bug bounty programs with a vetted researcher community | Commercial, per-engagement or program-based |

## Which one is actually best

For learning and internal testing, start with OWASP ZAP and Nmap, both free, then move to Burp Suite Professional when you outgrow them; it is what most working testers use daily. For validating exploitability, Metasploit remains the reference framework.

For a company that needs a report, the choice is between a traditional consultancy and a PTaaS platform. Consultancies offer deeper scoping conversations and are the safer choice for unusual environments. PTaaS platforms like Cobalt and HackerOne are faster to start, produce reports enterprise buyers recognize, and fit companies that expect to retest annually. Either way, ask who the individual testers are and whether the report includes retesting of fixed findings, because customers reviewing the report will ask you the same thing.

## Where this fits a SOC 2 program

SOC 2 does not strictly require a penetration test, but enterprise customers usually do, so most companies pursuing SOC 2 commission one annually and after major changes. The pentest report, the remediation of its findings, and the retest letter all become evidence in your compliance program. Screenata tracks that report and its remediation trail as evidence inside a [SOC 2 program](/solutions/soc-2); it does not perform penetration testing itself, and the firms and platforms above are the right place to buy one.
