Best AI Penetration Testing Tools in 2026
AI penetration testing tools use machine learning agents to probe applications, APIs, networks and cloud accounts for exploitable weaknesses, then report what they actually broke into along with a way to reproduce it. They sit between vulnerability scanners, which list possible flaws, and human-led pentests, which are scheduled and manual. They do not replace a security team's triage.
Quick answer
Ethiack ranks first for printed prices and its pay-only-if-exploited guarantee. Hadrian fits teams needing external exposure plus on-demand tests at €1,250. Horizon3.ai NodeZero suits internal and Active Directory attack paths.
Buyers of AI pentesting face two questions: how much of the work is automated, and what the report proves. This ranking asks what each vendor charges per test or per year, whether a finding comes with a working exploit, and who stands behind the result. Twelve vendors are placed by editorial judgment from their own pages as of October 2026. Smaller and mid-size vendors come before the largest suites, because the large platforms hide prices and assume a security team. HackerOne, Synack and RunSybil were left out of this edition and may be added once their pages have been checked. Prices not printed online are marked as quoted.

Ethiack
Ethiack lands first because it prints both a per-test price and an annual price, and attaches a guarantee: the pentest costs nothing unless a validated, exploited vulnerability is found. Its Hackian engine is paired with human ethical hackers, and retesting is unlimited. The vendor is a Portuguese company, which helps buyers who prefer an EU contracting party.
Strong on
- Pentest price of €3,000 per test is public, with a report promised within 5 days.
- Findings carry proof of exploit, step-by-step fixes and unlimited retesting.
- Core plan covers continuous pentesting for up to 50 assets, per the pricing page.
Weak on
- The €9,000 Core figure was a time-limited sale price over a €12,000 list price.
- Internal, mobile and cloud coverage sits in the custom Enterprise tier, not Core.
Skip it if: Large enterprises needing internal network or Active Directory attack paths from a single product on day one. Single web and API pentest; Core continuous plan lists at €12,000 per year, €9,000 in a sale.
- 2
Hadrian is a Dutch vendor with two products: Atlas for continuous external exposure, and Nova for on-demand agentic pentests that sign in to an app and map its routes. The €1,250 entry price for a Nova test is among the lowest printed in this ranking. It sits behind Ethiack because Atlas pricing is not published and the AI reasoning is shown in less detail.
Strong on
- Nova pentests are launched when needed, with the AI's reasoning and evidence visible.
- Results map to SOC 2, ISO 27001 and NIS2, useful for EU audits.
- A free external scan of one domain is offered before any contract.
Weak on
- Atlas pricing depends on asset count and is only available through a demo.
- Nova per-test price covers one scope; bundles are mentioned but not itemized online.
Skip it if: Teams wanting internal network or Active Directory testing, since Hadrian's pages center on internet-facing assets. Nova agentic pentests start at €1,250 per test; Atlas continuous exposure management is priced by total asset count.
- 3
Intruder began as a vulnerability scanner and added AI pentesting, so one login covers weekly scans, attack surface monitoring and an on-demand pentest. Its pricing page lists a Free plan, Cloud, Pro and Enterprise tiers plus the $3,500 pentest. The AI pentesting module is newer than the scanner, which is why it ranks third rather than higher.
Strong on
- Free plan plus a 14-day trial on Cloud lowers the cost of evaluating the scanner.
- Pentest report is promised within hours, and repos can be connected to scope it.
- Integrations include Slack, Jira, GitHub, GitLab and Teams on the plan table.
Weak on
- Paid plan prices are rendered by script, so the monthly figure for Cloud and Pro was not read.
- The scanner side is vulnerability management, not an autonomous red-team engine.
Skip it if: Organizations that need network-level attack path chaining across Active Directory or internal segments. AI web application pentests start at $3,500 per test; vulnerability management plans have a free tier and a 14-day trial.
- 4
Escape is a French offensive security vendor whose pitch is business logic testing: its DAST and AI pentesting products target authorization and workflow flaws in apps and GraphQL or REST APIs. It exposes a public API, CLI and MCP server. The ranking holds it at fourth because no prices are visible and the whitebox pentesting product is new.
Strong on
- Public API, CLI and MCP server mean pentest results can be pulled into pipelines.
- Product range spans AI pentesting, DAST, external network pentesting and attack surface management.
- Its published research includes a GraphQL security report and an open-source GraphQL Armor tool.
Weak on
- No plan price is printed, so budgeting requires a demo call.
- Marketing pages reuse placeholder text in several navigation panels, which makes feature scope harder to read.
Skip it if: Buyers who want a fixed per-test fee they can approve without talking to sales. Pricing is on request; the pricing page lists no plan prices as of October 2026.
- 5
Astra Security
Astra Security sells a scanner and pentests in one catalog, and prints more prices than most competitors: scanner plans from $69 per month, autonomous pentest at $2,999 per year, and pentests with certified testers at $5,999 per year. Its corporate footer lists a Delaware address. It ranks fifth because the plan tiers are many and the target definition limits coverage.
Strong on
- Autonomous pentest, scanner and human-led pentest tiers are priced openly on one page.
- A $7 one-week trial of the DAST scanner requires no credit card, per the pricing page.
- Pentest reports are aimed at SOC 2, ISO 27001 and HIPAA evidence.
Weak on
- Each plan counts targets, and a domain with its site tree is one target, so many apps multiply the cost.
- The API security and pentest platform products carry a coming-soon label on the pricing page.
Skip it if: Enterprises with hundreds of applications, where per-target pricing and custom SLAs become the real budget question. Autonomous pentest listed at $2,999 per year per target; a $7 one-week trial covers the DAST scanner.
- 6
Detectify is a Swedish attack surface and web application scanner that now lists agentic tooling and an MCP server. Starter starts at €0, Standard at €2,500 per year and Enterprise at €15,000. It sits sixth because it is a scanner first and an autonomous pentester only in part, and the platform fee excludes added domains and targets.
Strong on
- Starter plan costs €0 and includes REST and GraphQL API scanning for up to 5 users.
- Tier table shows what unlocks at each level, including SSO, SLA and custom tests.
- The vendor says 2,100+ organizations use the platform.
Weak on
- Added assets, domains, targets and IP ranges are charged on top of the platform fee.
- The Professional tier price was not captured from the page; it is likely quoted.
Skip it if: Buyers who specifically want a human-validated pentest report rather than scanner output. Standard is an annual platform fee; Starter is €0; extra domains, targets and IP ranges cost more.
- 7
Cobalt
Cobalt is a pentest-as-a-service platform where vetted testers and its Sage AI work in a credit model: one credit is the equivalent of eight hours of testing. It has added an autonomous pentest and an AI and LLM pentest. Ranked seventh because the AI layer assists humans, and pricing needs a quote, rather than being sold per test.
Strong on
- Standard, Premium and Enterprise tiers differ in start time, credit validity and support.
- Retesting is free within the PTaaS model, according to the pricing FAQ.
- Services reach beyond web apps to mobile, cloud, network and red teaming.
Weak on
- Credits do not roll over into a new contract, so unused budget is lost at term end.
- No list prices appear online; every package is a quote.
Skip it if: Teams that want a fully autonomous test with no human tester or scheduling step. Credit packages are quoted; one credit equals 8 hours of testing and does not roll over after the contract year.
- 8
XBOW
XBOW is an autonomous offensive security platform that attacks web applications and APIs and reports only findings it exploited. Its site cites a HackerOne ranking and an October 2026 Chrome sandbox escape. Pricing is usage-based on a quote, and the product is sold on AWS, Google, Oracle and Microsoft marketplaces. It is eighth because list prices are hidden and its record is mostly self-reported.
Strong on
- Every finding carries the working exploit, request, response and reproduction steps.
- Stated policy is no model training with customer data, per the site's compliance section.
- Re-tests run automatically after a fix is deployed.
Weak on
- Pricing is scoped per environment, with no printed entry price.
- Focus is applications and APIs, not internal network or identity attack paths.
Skip it if: Small teams with one or two apps looking for a low fixed price on a single test. Usage-based pricing scoped to the environment; a quote is required and cloud marketplace purchase is offered.
- 9
Horizon3.ai NodeZero
Horizon3.ai NodeZero is an autonomous pentesting platform that runs real attack techniques against production without agents and then re-tests fixes. It covers internal, external, cloud, Kubernetes, Active Directory and, newly, web apps. It ranks ninth since it is quote-only, built for security teams that already run a vulnerability program, and its web app testing is the newest part.
Strong on
- Covers internal networks, Active Directory, cloud and Kubernetes in one product line.
- Fix verification closes the loop with a re-test of the same attack path.
- The site lists an MCP server and PCI and NIS 2 compliance views.
Weak on
- No price is published, and packages must be requested through sales.
- WebApp pentesting was a recent product launch, so depth lags the network engine.
Skip it if: Small companies without a security analyst to act on attack-path output. Pricing is not printed; NodeZero is sold in packages through a demo, as of October 2026.
- 10
Pentera
Pentera is an automated security validation platform that safely emulates attacks across internal networks, external surfaces and cloud identity, with newer AI-native web app testing. Its Trust Center lists SOC 2 Type II, ISO 27001:2022 and ISO 42001, and EU processing for its subprocessors. It is tenth because the suite targets large programs and prices are hidden.
Strong on
- Separate products for internal, external and cloud validation, plus remediation orchestration.
- Trust Center lists SOC 2 Type II, ISO 27001:2022 and ISO/IEC 42001 certificates.
- Sector11 services add expert-led testing on top of the automation.
Weak on
- No prices or free trial are shown on the pages checked.
- Buying several products (Core, Surface, Cloud, Resolve) spreads cost across modules.
Skip it if: Startups wanting a quick per-test pentest report for a single web application. Pricing is not published; Core, Surface, Cloud and Resolve are sold separately on request.
- 11
Burp Suite Professional
Burp Suite Professional is a web penetration testing toolkit from PortSwigger in which a human tester drives the proxy, Repeater and scanner, with Burp AI added inside Repeater. It ranks eleventh because it is a toolkit for security staff, not an autonomous test that returns a finished report. PortSwigger states that AI data is not kept by its AI provider or used for training, and that AI can be disabled.
Strong on
- Burp AI works inside Repeater and can be switched off entirely in settings
- More than 300 BApp Store extensions and Bambdas let teams adapt the tool
- PortSwigger says AI data is never stored by the provider or used for model training
Weak on
- Burp AI cannot run offline, and PortSwigger lists no local model option yet
- Findings depend on a skilled tester driving the tool, so small teams without one gain little
Skip it if: Companies without a security engineer that want a hands-off test and a finished report delivered. The Professional page shows a $499 buy button; billing period and AI credit allowance were not verified.
- 12
Aikido Security is a Belgian application security platform whose pentest line runs AI-driven tests next to its code, cloud and runtime scanners. It ranks twelfth because pentesting is one module inside a broader suite and covers one application and its APIs per assessment. The pricing page promises no fee when a test finds no High or Critical issue, and prices rise with scope.
Strong on
- Pentest price is set from repository, endpoint and role analysis, starting at €45
- Pricing page says no High or Critical finding means no payment
- Trust page lists SOC 2 Type II, ISO 27001:2022 and ISO 42001
Weak on
- One credit pool also funds code review and analysis, so pentests compete with them
- Each assessment covers a single application and its APIs, not a whole network
Skip it if: Teams that need internal network or Active Directory attack-path testing instead of application-level tests. A typical fixed-scope pentest is €3,500; Rightsized pentests run from €45 to over €25,000 by scope.
How these AI penetration testing tools were judged
Does the tool prove a finding is exploitable?
The strongest claim an AI pentest can make is that it exploited the flaw, not that a signature matched. XBOW says findings arrive with the exploit, request and response, Ethiack validates every confirmed risk with proof of exploit, and Hadrian reports only validated exposures. Scanner-led tools such as Detectify and Astra's scanner list issues first and test deeper in separate tiers. Vendor numbers on accuracy or speed are self-reported, so ask for a sample report and one test against a staging app you know is vulnerable before you believe any figure.
How much does an AI pentest cost?
As of October 2026 the printed entry prices are €1,250 per Hadrian Nova test, €3,000 per Ethiack pentest, $3,500 per Intruder AI pentest and $2,999 per year for an Astra autonomous pentest. Detectify's Standard plan is €2,500 per year. Cobalt, XBOW, Horizon3.ai, Pentera and Escape show no price and want a call first. A low per-test fee covers one scope only, so compare against what you must test each year, and check what retesting, extra assets and reports cost on top, since those lines often decide the final bill.
What happens to your code and findings in an AI pentest?
Pentest tools touch production URLs, credentials and sometimes source repositories, so the handling policy matters. XBOW states it does no model training with customer data, and Pentera's Trust Center lists SOC 2 Type II, ISO 27001:2022 and EU processing for several subprocessors, including a generative AI provider. For the other vendors, the vendor's policy was not checked for this ranking. Ask in writing where findings are stored, how long, which LLM provider sees your traffic, and whether test data can be deleted on request.
How hard is it to switch AI pentest vendors?
Per-test products are the easiest to leave, because Ethiack, Hadrian Nova and Intruder charge by test. Annual platform fees from Detectify, Ethiack Core and Astra lock in a year, and Cobalt credits expire at the end of the contract year. Quoted platforms such as Horizon3.ai and Pentera tend to run multi-year agreements. Before signing, ask for findings in an exportable format and confirm that retest history, asset inventories and issue-tracker links survive a termination. Reports used for SOC 2 stay valid after you leave.
Which AI pentesting tool fits a startup and which an enterprise?
A startup preparing for SOC 2 wants a report and a fixed fee, which points to Ethiack, Astra or Hadrian Nova. A company with dozens of apps and a release pipeline should look at continuous products such as Ethiack Core, Escape or XBOW. Enterprises that need internal network, Active Directory and cloud identity attack paths are the target of Horizon3.ai NodeZero and Pentera. European financial buyers should note that Hadrian and Ethiack map output to DORA or NIS2 on their own pages.
How to choose an AI penetration testing tool in three steps
- Decide what must be attacked, then match the vendor. List what you need tested: a handful of web apps and APIs, the whole internet-facing estate, or internal networks and cloud identity. Web apps and APIs point to Ethiack, Hadrian Nova, Intruder, Escape or XBOW. External sprawl points to Hadrian Atlas or Detectify. Internal networks and Active Directory point to Horizon3.ai NodeZero or Pentera. Write the scope as a short list of URLs, IP ranges and account types, because every vendor prices against it and a vague scope produces vague quotes.
- Run a proof test against a known weak target. Ask each shortlisted vendor to test the same staging application, one that has a few flaws your team has already found. Count how many the tool reproduces with a working exploit, how many false positives it reports, and how long the report takes. Free or low-cost starts exist, such as Hadrian's free external scan, Astra's $7 scanner trial and Intruder's 14-day trial. Run all trials in the same week and keep the results in a sheet so the comparison is not decided by the best demo alone.
- Check the report against your auditor's needs. If the pentest feeds SOC 2, ISO 27001, PCI or NIS2 evidence, ask your auditor whether an AI-generated report is accepted or whether a named human tester must sign it. Cobalt and Astra offer certified pentesters, while Ethiack combines AI with ethical hackers. Confirm the report format, retest policy and how many fixes you can verify in the price. Ask for a sample report before buying, and confirm that the vendor will let you share the report with customers who ask for proof of testing.
Frequently asked questions
What is the best AI penetration testing tool in 2026?
Ethiack ranks first in this list because it prints a €3,000 per-test price and a €12,000 annual price, and refunds the pentest unless a validated exploit is found. Hadrian and Intruder follow. The order is editorial, based on vendor pages checked in October 2026, and a larger enterprise may rank NodeZero or Pentera higher.
How much does an AI pentest cost?
Among vendors that publish prices in October 2026, a single AI web pentest costs from €1,250 (Hadrian Nova) to €3,000 (Ethiack) or $3,500 (Intruder). Annual plans run from €2,500 (Detectify Standard) to €12,000 (Ethiack Core list price). Cobalt, XBOW, Horizon3.ai, Pentera and Escape quote on request.
Is an AI pentest accepted for SOC 2 or ISO 27001?
Acceptance depends on your auditor, not the tool. Ethiack, Hadrian, Astra and Cobalt describe reports mapped to SOC 2 and ISO 27001, and Cobalt and Astra include certified testers. Ask the auditor in advance whether a machine-run test is sufficient, and request a sample report from the vendor before purchasing.
What is the difference between a vulnerability scanner and an AI pentest?
A scanner matches targets against known checks and lists potential issues. An AI pentest agent chains steps, signs in, and tries to exploit what it finds, then reports what worked. Intruder, Detectify and Astra sell both, so one login can cover weekly scans and a deeper test.
Can AI penetration testing tools damage production systems?
Any active test can cause disruption if misconfigured. XBOW describes a command checker that blocks destructive actions, and Horizon3.ai says NodeZero runs safely in production without agents. Vendor claims are not guarantees, so start on staging, agree testing windows, and keep rollback plans for anything stateful, such as payment or email flows.
Which AI pentesting tool covers internal networks and Active Directory?
Horizon3.ai NodeZero lists internal pentesting, Active Directory, Kubernetes and cloud, and Pentera sells Core for internal validation and Cloud for identity and hybrid environments. Ethiack lists internal coverage only in its custom Enterprise tier. Most other tools in this ranking focus on web apps, APIs and internet-facing assets.
Do these tools replace human pentesters?
Not entirely. Cobalt and Astra keep human testers in the loop, and Ethiack pairs its Hackian engine with ethical hackers. Autonomous tools shorten the time to a first report and allow frequent retests, while manual testing still helps with creative business-logic attacks and for audit reports that require a named tester.
Which AI pentest tools are available from European vendors?
Ethiack is a Portuguese company, Hadrian a Dutch B.V., Detectify a Swedish company, Escape a French company and Intruder a UK company, per the sources checked. Pentera is Israeli, and XBOW, Cobalt, Astra and Horizon3.ai are US companies. Data location still needs a written answer from each vendor.
