Selecting the right penetration testing company is not just a procurement decision. It affects how well your organization understands real security risk, how useful your remediation work will be, whether your product will be more secure, whether your organization is stronger against attacks and whether your pentest report will hold up in a customer review, an audit, a board discussion or a vendor risk assessment.
This article aims to serve as an honest directory of penetration testing companies, based on our experience over the past 10 years and positive feedback from conversations with customers who use multiple pentest providers. These penetration testing companies are known for their track record of published security research, their staff's skills, and their solid market reputation.
We include Blaze transparently alongside other providers, including direct competitors. No company has paid to be included. This is not a ranked "best penetration testing companies" list because no definitive list exists. Most ranking articles are written to place the publisher in the first position, which is not especially useful for buyers. Instead, this guide is designed to help you compare penetration testing companies by buyer fit, specialization, region, delivery model, and common tradeoffs.
How we selected companies in this directory
The companies in this directory were selected based on signals such as:
- Proven track record in manual penetration testing
- Positive industry feedback and market reputation
- Technical depth of the team
- Published security research, public reports, tools, advisories, or conference work
- Experience with real-world attack paths, not just automated vulnerability scanning
- Ability to deliver clear, actionable, audit-ready reports
- Specialization in areas such as web applications, APIs, mobile apps, cloud, infrastructure, embedded systems, red teaming, product security, blockchain, cryptography assessments, compliance, or enterprise-scale security programs
The list is presented alphabetically within each category to keep the selection neutral.
We've divided the list into two categories: boutique penetration testing companies and large corporations offering penetration testing services. We didn't include crowdsourced security testing firms and bug bounty providers on this list. Whether you prefer a boutique firm's specialized services or a large corporation's extensive resources and more robust solution portfolio, this guide offers valuable information on reputable security testing providers.
If your company is looking to hire a firm for pentest services, you are encouraged to use this resource to find the right penetration testing partner to enhance your organization's cybersecurity posture.

How much do pentest companies charge in 2026?
Penetration testing pricing varies widely because the scope varies widely. A small unauthenticated marketing website is not priced like a multi-tenant SaaS product with APIs, SSO, admin roles, payment flows, mobile apps, cloud infrastructure, and compliance evidence requirements.
As a planning range, many commercial penetration tests in 2026 fall somewhere between $5,000 and $35,000, depending on scope and complexity. More complex work, such as cloud security assessments, internal network penetration testing, product security, IoT testing, source code-assisted reviews, or red teaming, can cost significantly more.
| Engagement type | Typical 2026 planning range | Notes |
| Small web application penetration test | $5,000 to $15,000 | Usually, a limited scope, fewer roles and fewer complex workflows. |
| Standard web application penetration test | $10,000 to $30,000 | Common for SaaS, customer security reviews, and compliance evidence. |
| API penetration test | $5,000 to $20,000 | Price depends on endpoints, authentication, roles, and business logic. |
| Mobile application penetration test | $5,000 to $30,000 | Price depends on platforms, API scope, authentication, and local storage risks. |
| External network penetration test | $5,000 to $35,000+ | Depends heavily on the number of IPs, exposed services, and the depth of testing. |
| Cloud penetration test | $10,000 to $40,000+ | Depends on AWS, Azure, GCP, IAM, architecture, services, and account structure. |
| Product security assessment | $25,000 to $100,000+ | Often includes architecture, app, API, cloud, code-assisted testing, and business logic. |
| Red team engagement | $50,000 to $150,000+ | Depends on objectives, duration, social engineering, internal testing, and rules of engagement. |
These are planning ranges, not fixed quotes. A reputable penetration testing company should scope the number of applications, APIs, user roles, endpoints, IP addresses, cloud accounts, environments, integrations, testing objectives, reporting requirements, and retesting expectations before giving a final price.
A good penetration testing quote should make the following clear:
- What is in scope
- What is out of scope
- How many testing days are included
- Who will perform the work
- What methodology will be used
- Whether testing is manual, automated, or both
- What deliverables are included
- Whether retesting is included
- Whether the report is suitable for compliance or customer evidence
- Whether findings can be exported to Jira, CSV, PDF, or a PTaaS platform
- What support is available after delivery
Low-cost penetration testing quotes can be tempting, especially when the buyer only needs a compliance report. However, very cheap pentests often involve limited manual testing, junior testers, automated scanning, generic reporting, or little remediation support.
At the same time, the highest quote is not always the best. Some large providers may add unnecessary line items or scope an engagement more broadly than the buyer needs. The right quote is the one that matches your actual risk, scope, business needs, and reporting requirements.
On AI, LLM and agentic pentesting in 2026
AI is starting to change how penetration testing companies work, but the most interesting shift is still early: agentic pentesting.
Agentic pentesting refers to the use of AI agents to assist with tasks such as reconnaissance, attack-path mapping, payload generation, vulnerability validation, report drafting, and remediation guidance. Instead of using AI only as a chatbot or code assistant, agentic systems can reason across multiple steps in a testing workflow and assist testers throughout an engagement.
This area is promising, but it is still too early to assess its real effectiveness across professional penetration testing engagements. The quality, reliability, safety, and consistency of agentic AI are very promising, but it still needs to be proven in real-world testing environments that require a careful approach. For now, human expertise remains essential, especially for business logic flaws, authorization testing, chained vulnerabilities, exploit validation, and understanding real business impact.
We expect more penetration testing companies to incorporate agentic AI into their workflows soon. The likely near-term use case is not to replace penetration testers, but to help experienced consultants work faster, document better, explore attack paths more efficiently, and improve remediation support for clients.
Note on traditional pentesting, PTaaS and crowdsourced security testing
Buyers often compare traditional penetration testing companies with PTaaS providers, crowdsourced security testing platforms, and bug bounty companies. These models overlap, but they are not the same.
| Model | Best for | Strengths | Limitations |
| Traditional penetration testing | Formal assessments, compliance evidence, pre-release testing, customer security reviews, board reporting | Clear scope, named consultants, predictable deliverables and a formal report | Point-in-time unless recurring testing is planned. |
| PTaaS | Recurring testing, fast-moving SaaS teams, remediation workflows, real-time findings, multiple tests per year | Platform-based workflow, finding tracking, retesting, exports and easier collaboration | Quality still depends on the tester's skill and methodology. |
| Crowdsourced testing/bug bounty | Mature security programs, broad external researcher coverage and continuous vulnerability discovery | Large researcher pool, continuous coverage, creative testing | Not always accepted as a formal pentest replacement, it requires strong triage and remediation processes. Lots of known problems with triaging. |
This directory focuses mainly on boutique penetration testing companies and cybersecurity service providers. Crowdsourced security platforms and bug bounty providers may be valuable, but they should usually be evaluated separately from other penetration testing providers.
