Fleuret is a European AI pentesting platform built around compliance deadlines, and teams like that each finding comes with a proof of concept they can replay. As security programmes grow, though, some teams want their code tested with source access, checks on every pull request, or a lower entry price than €4,000 a pentest. If you are weighing your options, these are the five Fleuret alternatives worth a close look:
- AISafe Labs
- Ethiack
- XBOW
- MindFort
- Tenzai

What is Fleuret?
Fleuret is a Paris-based AI pentesting platform for web applications, REST and GraphQL APIs and external infrastructure. Its agent, Émile, coordinates specialist AI agents in grey-box pentests, and a separate validator confirms each finding with a read-only, non-destructive proof of concept you can replay. A second agent, Hortense, uses your code, domains and past pentests to suggest what to test next, and a person with launch rights starts each pentest.
Reports include a remediation for each finding and map to NIS2, DORA, ISO 27001 and SOC 2, and the platform is hosted in Europe. Fleuret is sold in pentest credits: a one-off pentest costs €4,000, yearly plans run from €12,000 for 3 pentests to €50,000 for 15, and a free self-serve plan includes scanners for up to 10 repositories.
Why organizations look for Fleuret alternatives
Fleuret does a lot well, but teams usually start looking elsewhere for one of three reasons.
1. Testing is grey-box only. Fleuret tests running applications with test accounts for each role. It does not offer white-box pentests or a code audit, and it uses your code only to decide what to test. There is no SAST, dependency, secrets or IaC scanning on its paid plans, and no pull request review.
2. Each pentest is a significant purchase. A pentest costs €4,000 on its own, or 1 credit on a yearly plan from €12,000 for 3 credits. Extra credits cost €4,000 each and do not roll over, and pentests start only when someone launches them. Teams that want to test every release, or many applications, can find the cost climbs quickly.
3. Parts of the product are still being built. Fleuret's FAQ lists Active Directory, mobile and cloud pentests as on the roadmap, and its funding announcement describes fix help, automatic re-testing and integrations with engineering tools as work in progress. Findings come with a written remediation rather than a patch.
Top 5 Fleuret alternatives
Here is how the leading alternatives compare, starting with the one we build.
#1 AISafe Labs
AISafe Labs is an application security platform that uses AI agents to test your code and your running application the way an attacker would. It runs code audits, black-box and white-box pentests, pull request reviews and continuous monitoring from one place, and its free plan includes a full SAST suite.
Like Fleuret, AISafe Labs runs AI pentests that prove issues against your live application. The difference is that it also reads your code. Its agents build a model of your codebase and trace user input from where it enters to where it reaches a sensitive operation, which is how they find broken access control between teams and business-logic errors before release. A separate triage pass then confirms each finding, merges duplicates that share a root cause and shows its reasoning.
Key features
- Code Audit: AI agents review the whole repository and report evidence-backed findings with exact code locations, the path user input takes, and remediation guidance.
- Code Scan, free: SAST, AI SAST, dependency scanning, secrets detection, licence risk and IaC scanning on the free Basic plan, with no card required.
- Black-box and white-box pentests: agents probe your live application over HTTP and in a browser, and white-box tests combine source access with live confirmation, so findings come with evidence you can replay.
- Pull request security review: every pull request is reviewed for security defects, using what earlier audits learned about the project.
- Endpoint monitoring: AISafe re-runs the proof of each fixed finding against your live application on a schedule and alerts you when a fix regresses.
- Fix verification (beta): check a patched source revision against the original finding before you deploy it.
- Built for coding agents: findings, remediation guidance and fix verification are available through the AISafe API, so your own coding agent can read a finding, write the patch and start the verification itself.
- Fits your workflow: export findings to Jira or Linear, get alerts in Slack or Teams, and run AISafe on your own infrastructure if you need to.
Why AISafe Labs stands out as a Fleuret alternative
- It tests with source access. Code audits and white-box pentests read your code and confirm issues on the live application, so the agents can find flaws that grey-box testing cannot see.
- It costs less to start and to repeat. The Basic plan is free with no card required, Pro starts at $40 a month, and the price of each code audit depends on the size of the codebase and is shown before you start.
- It checks every change. Pull request security review looks for security defects in each pull request, and endpoint monitoring re-tests fixed findings on a schedule.
- It helps with the fix, not only the finding. Your coding agent can read a finding through the API and write the patch, and fix verification tests the patched revision against the original finding before you deploy it.
Pricing
The Basic plan is free and includes the full SAST suite. Pro starts at $40 a month and includes the same number of credits, which pay for code audits, pentests and continuous work; the price of a code audit depends on the size of the codebase and is shown before you start.
Ideal for: Teams that want more than a pentest: engineering and security teams that need to find logic and access-control flaws in code and in the running application, and close the loop from finding to verified fix, without moving to an enterprise contract.
#2 Ethiack
Ethiack is an autonomous ethical hacking platform. Its AI agent, Hackian, continuously maps your attack surface, tests web apps, APIs and exposed services, and proves each confirmed finding with a non-destructive exploit. Human ethical hackers join for Expert pentests.
Ethiack publishes its prices: a one-off Pentest On-Demand starts at €3,000 per test, and the Core continuous plan costs €12,000 a year for up to 50 assets. Internal network testing through its Beacon agent is part of custom Enterprise plans.
Key features
- Continuous attack surface mapping and testing by the Hackian AI agent
- Evidence and steps to reproduce for each confirmed finding
- Unlimited retesting on the Core plan and up
- A CI/CD step that tests the deployed URL
- Two-way Jira Cloud sync
- A 30-day free trial
Ideal for: Teams that want continuous external testing at a published price, with human-led pentests available when they need them.
#3 XBOW
XBOW is an autonomous AI pentesting platform that attacks running web applications and APIs, proves each finding with a working exploit and retests fixes. You can upload source code, API specs and documents as optional context to guide its testing.
XBOW focuses on pentesting, so it does not audit source code, scan dependencies or review pull requests. It is sold by quote as packages of Attack Credits, which each assessment draws down, and it does not publish prices on its website.
Key features
- Black-box pentests of web applications and their APIs
- A validated exploit with reproduction steps for each finding
- Free, unlimited retests of a deployed fix
- Source code, API specs and documents as optional context
- An API that can start a pentest on merge or from your own scheduler
- Self-hosted deployment through sales
Ideal for: Security teams that want autonomous, exploit-backed pentesting of running web applications and APIs, and buy through a usage-based contract.
#4 MindFort
MindFort is an autonomous AI pentesting platform whose agents attack running web apps, APIs and networks, prove findings with a working exploit, open patch pull requests and retest after the fix. Linking a GitHub repository adds white-box code assessment, and a GitHub app reviews each pull request.
MindFort is priced as a monthly plan with a credit allowance. Starter costs $499 a month for 250 credits and 1 target, and Scale costs $999 a month for 800 credits and unlimited targets.
Key features
- Pentests of web apps, APIs, MCP servers and IPs
- White-box assessment with a linked GitHub repository
- Pull request review through a GitHub app
- Scheduled assessments, from daily to monthly
- Patch pull requests on GitHub, at 1 credit each
- Jira and Linear integration, and private deployment on Enterprise
Ideal for: Teams on GitHub that want AI pentests with patch pull requests and a published monthly price.
#5 Tenzai
Tenzai is an autonomous AI penetration testing platform that discovers, chains and exploits vulnerabilities across web apps, APIs, mobile and AI apps, and external and internal networks, in black-, grey- or white-box mode. Every finding arrives with a reproducible exploit.
Tenzai does not publish prices; you request a demo or a pentest, and it also sells through service-provider and reseller partners.
Key features
- Black-, grey- and white-box tests of web apps and APIs
- Mobile app, AI app and MCP tool testing
- External and internal network testing, mapped to MITRE ATT&CK
- An exploit-proven finding with evidence for each issue
- Fix guidance, coding-assistant prompts and generated WAF rules
- Incremental runs that test only what changed
Ideal for: Larger security teams that want one autonomous platform across applications and networks, and buy through sales.
How to choose the right Fleuret alternative for you
The right choice depends on what you need your security tooling to catch and how your team works. When you compare options, check:
- What you need tested. Decide whether you need your source code checked, your running application tested, or both, and look for a tool that covers each without a second contract.
- How findings are proven. Ask each vendor how a finding is confirmed, and run a trial on your own application to see how many are real.
- Where in the workflow it runs. Some tools test the deployed application on a schedule; others also review each pull request before it merges.
- How fixes get done. Look at whether the tool writes patches, guides your own coding agent, and verifies that a fix works.
- What it costs as you grow. Compare billing models, per pentest, per asset, per credit or per developer, and whether prices are published or only available from sales.
