*PharosOne sells pentests and AI agent testing and wrote this article. Our own prices are not part of the market sample and are listed separately at the end.*

**In short.** In October 2026 five different services are sold as a "pentest" that touches AI, and their published prices run from about €1,250 to over €40,000 because the scope and the human effort differ. Most autonomous AI pentests of a web application are listed at $3,000–4,000 per test ([Intruder](https://www.intruder.io/ai-pentesting), [Aikido](https://www.aikido.dev/pricing), [Cobalt](https://www.cobalt.io/pricing)); the range in our table runs from €1,250 ([Hadrian](https://hadrian.io/pricing)) to $4,181 ([Synack Sara](https://www.synack.com/pricing/)), and some vendors add a platform fee. Manual pentests from European boutiques start at €6,500–6,750 for five days ([CyberScore](https://cyberscore.nl/pentest-kosten.html), [AWARE7](https://a7.de/en/services/penetration-testing/)). Human-led tests of AI systems run from €4,800 for a simple chatbot to €12,000–20,000 for agents with tools ([FlowHunt](https://www.flowhunt.io/services/ai-chatbot-penetration-testing), [QualityMax](https://qualitymax.io/services)). A 30-day red team on the UK G-Cloud catalogue costs £29,250–39,000 ([Claranet](https://assets.applytosupply.digitalmarketplace.service.gov.uk/g-cloud-15/documents/92809/539781814990276-pricing-document-2025-12-19-1816.pdf)). Compare quotes by the number of tester days and the target; a headline price alone says little.

## Key facts

- Updated: 23 October 2026.
- Named prices: only where the vendor publishes the price on its own page or in a public procurement listing (UK G-Cloud). Each named price links to that page as a numbered source and was checked on 22 October 2026.
- Segment ranges: our compilation of 727 price points naming 283 vendors, buyers and publishers, collected on 21–22 October 2026. By source: 320 from vendor price pages, 118 from press articles, 101 from rate cards (90 of them UK G-Cloud), 56 from public tenders, 55 from review sites, 52 from marketplace listings and 25 from market surveys. Each point records the vendor, segment, country, currency, price, unit, source type, source URL and the date seen. In the statistics, repeated sightings of one price (15 rows) count once, and the 168 points we rated low confidence are left out of list-price medians.
- Data: all 727 price points as CSV, [ai-pentest-prices-2026-10.csv](/data/ai-pentest-prices-2026-10.csv), with vendor, offer, price as published, currency, unit, source type, source URL and date checked; CC BY 4.0. The [README](/data/README.md) maps each segment count and median below to its rows.
- Currency: named prices are shown in the currency the vendor publishes. Medians and ranges in euros use the ECB rates of 21 October 2026 (1 EUR = 1.1234 USD = 0.83825 GBP).
- Regions: mostly the UK, continental Europe and North America.
- Disclosure: PharosOne sells pentests. Its prices are not in the sample and are listed in the last section.

## Why does an autonomous pentest cost $3,500?

Because AI agents do the testing and the scope is one web application. The published descriptions above agree on one application and its APIs and results in hours or a few days; several vendors (for example Hadrian) market the report as SOC 2 or ISO 27001 evidence, so check with your auditor whether an autonomous test is accepted. Some add a person: Stingrai's hybrid tier has testers validate every finding, and Fencer sells a human-led test at twice the autonomous price. When the target is an AI agent rather than a web application, check whether the offer has a mode for it; Aikido documents one that tests prompt injection, tool abuse and memory poisoning in an app's LLM features [[2]](https://help.aikido.dev/pentests/configure-a-pentest/testing-ai-capabilities).

## What does a tester day cost?

Published sell rates differ by country. In the sample, 74 UK rates from vendor pages and rate cards have a median of about €1,374 per day, US rates about €1,420 (23 rates), German rates about €1,200 (7 rates), French rates about €700 (7 rates) and Spanish rates about €700 (5 rates). UK G-Cloud rate cards are a narrower population: their median for a lead penetration tester is £1,200, and Dionach lists AI penetration testing at £1,600 per day [[19]](https://assets.applytosupply.digitalmarketplace.service.gov.uk/g-cloud-15/documents/92699/119754442392008-pricing-document-2026-01-29-1456.pdf).

Dividing a fixed price by a day rate gives a rough idea of the days in it, as an illustration only: a €12,000 quote is 10 days at €1,200 and 8.7 days at €1,374. The days actually on target are whatever the vendor's scope states; part of every fixed price pays for the report, the debrief and the retest. A price without the days next to it cannot be compared.

## What do AI system tests cost?

Human-led tests of AI systems with published prices form three tiers. A simple chatbot with one knowledge base and no tools: €4,800 for two days at FlowHunt. A retrieval system with one to three tools: €7,200–9,600 for three to four days. Agents with several tools: €12,000 and up for five days or more at FlowHunt, €12,000–20,000 for two to three weeks at QualityMax. Schellman starts at $16,000 for about two weeks and ZioSec at $10,000. On the UK G-Cloud catalogue, day rates for AI testing range from about £1,065 to £1,650.

## How should you compare quotes?

1. Ask for the number of tester days and who does them.
2. Ask what the target is: a web application, an AI agent with its tools, or both.
3. Ask whether a person reproduces every finding and signs the report.
4. Ask what the retest covers and for how long.
5. Ask which framework controls the report maps to: SOC 2 CC4.1, PCI DSS 11.4, DORA Art. 24–25, AIUC-1.

## What does PharosOne charge?

| [Human pentest](/knowledge/human-pentest), web, API, cloud, code | from €9,500; most projects €12,000–18,000 | 7+ senior days on one application and its API with up to 3 roles; report in week 3 |

## FAQ

### How much does a pentest of an AI agent cost in 2026?

Human-led tests of AI systems with published prices start at €4,800 for a simple chatbot over two days (FlowHunt) and reach €12,000–20,000 for agents with tools over two to three weeks (FlowHunt, QualityMax). Schellman states no less than $16,000 for one AI red team engagement; ZioSec starts AI agent pentests at $10,000. Prices checked on 22 October 2026.

### Why do some AI pentests cost $3,500?

Those are autonomous tests in which AI agents test one web application and its APIs, with results in hours to a few days by the vendors' own descriptions: Intruder $3,500, Cobalt $3,500 (offer until 31 December 2026), Aikido €3,500, Snyk 4,000 credits at $1 each, Stingrai $3,000. The application is the target. Aikido also documents a mode that focuses on an application's AI features.

### What is a senior pentester's day rate in Europe?

In 74 published UK sell rates collected on 21–22 October 2026 the median is about €1,374 per day; UK G-Cloud rate cards list lead penetration testers at a median of £1,200. German published rates have a median of about €1,200 (7 rates); French published rates about €700 (7 rates) and Spanish about €700 (5 rates). On G-Cloud 15, Dionach lists AI penetration testing at £1,600 per day.

### Is the retest usually included?

Most vendors that publish prices include one retest. Windows differ: 30 days at FlowHunt, 90 days at CyberScore, three rounds over 12 months at Software Secured, unlimited at Intruder. Paid extra rounds are typically 10–30% of the test price.

### What does PharosOne charge?

PharosOne's own prices are listed separately at the end of this article and are not part of the market sample: €3,900 for the AI-run assessment of one agent, from €15,000 for the human pentest of an AI agent, from €9,500 for a web, API or cloud pentest.
