Tenzai is one of the most heavily funded newcomers in AI penetration testing, and teams like that every finding it reports comes with a working exploit. Its prices are not published, though, and some teams want their code checked as well as their running applications, or fixes handled closer to the pull request. If you are weighing your options, these are the five Tenzai alternatives worth a close look:
- AISafe Labs
- XBOW
- Horizon3.ai
- Ethiack
- MindFort

What is Tenzai?
Tenzai is an autonomous AI penetration testing platform. Its agents discover, chain and exploit vulnerabilities across web applications, APIs, mobile apps, AI apps and MCP tools, and external and internal networks, and tests can run in black-, grey- or white-box mode. Every finding arrives exploit-proven, with evidence a team can reproduce.
For fixes, Tenzai gives step-by-step guidance, prompts for a coding assistant and ticket creation, and it can generate a targeted WAF rule and help deploy it in audit mode before blocking. Incremental runs test only what changed in an application. Tenzai was founded in 2025 and announced a $75 million seed round that year. It is sold through a demo or a pentest request, and through service-provider and reseller partners.
Why organizations look for Tenzai alternatives
Tenzai does a lot well, but teams usually start looking elsewhere for one of three reasons.
1. Prices are not published. Tenzai's pricing page lists no plans or prices, and the site offers no free plan or trial. Every engagement starts with a demo or a pentest request, which makes it hard to compare costs or to try the product on a small project first.
2. It tests running applications, not code on its own. White-box mode is listed, but Tenzai does not describe a standalone code audit, SAST, dependency, secrets or IaC scanning, or pull request review. Teams that want to find flaws in code before it ships, or check every change at review time, need a second tool.
3. The fix stays with your team. Findings come with guidance, coding-assistant prompts and WAF rules, which help to contain an issue, but Tenzai does not describe writing patches or opening fix pull requests. Ticket creation is mentioned without a named Jira or Linear integration, and its public documentation was not available to review.
Top 5 Tenzai 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 Tenzai, 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 Tenzai alternative
- Its prices are published. The Basic plan is free with no card required, Pro starts at $40 a month, and the price of a code audit is shown before it starts, so you can try it on your own code without a sales call.
- It covers your code and your live application. Code audits and the free SAST suite find flaws in source code, and white-box pentests combine that source access with live confirmation.
- It catches issues before they merge. Pull request security review checks every change for security defects, using what earlier audits learned about the project.
- 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 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.
#3 Horizon3.ai
Horizon3.ai's NodeZero is an autonomous pentesting platform that attacks internal networks from a host inside your network, external attack surfaces, and AWS, Azure and Kubernetes environments, chaining weaknesses and proving each one. NodeZero WebApp, sold separately, crawls, logs into and attacks running web apps and their APIs.
NodeZero is priced per asset, from $15 per asset per test on Flex or $50 per asset a year with unlimited testing on Core. NodeZero WebApp Flex costs $10,000 per app per test.
Key features
- Internal network pentests from a host inside your network
- External attack surface and cloud testing for AWS, Azure and Kubernetes
- Proof and an attack path for each finding
- NodeZero WebApp for running web apps and their APIs
- Fix guidance and one-click retests
- Jira and ServiceNow integration
Ideal for: Security teams that want to test their networks, external surface and cloud the way an attacker would chain them, priced per asset.
#4 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

- 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.
How to choose the right Tenzai 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.
Make the switch from Tenzai to AISafe Labs
Tenzai is a strong choice for autonomous, exploit-proven testing across applications and networks. If you also want your code checked, pull requests reviewed and fixes verified, at a price you can see before you start, AISafe Labs covers that in one platform.
You can start on the free Basic plan, which includes the full SAST suite, and run your first code audit in minutes. Start for free.
