Hadrian combines continuous external attack surface management with on-demand agentic pentests, and teams like that every finding comes with the requests and responses that prove it. As applications grow, though, some teams want their code tested as well as what is exposed on the internet, or a published price for continuous coverage. If you are weighing your options, these are the five Hadrian alternatives worth a close look:
- AISafe Labs
- Ethiack
- XBOW
- Pentest-Tools.com
- Horizon3.ai

What is Hadrian?
Hadrian is an offensive security platform founded in Amsterdam in 2021. Atlas, its attack surface management product, continuously discovers domains, DNS records, IPs, certificates, cloud services and applications a company exposes on the internet and tests them, with passive scans every hour and tests triggered by changes. Nova runs on-demand agentic pentests of one application at a time, signing in as every role, and attaches every request and response to each finding.
Findings come with remediation guidance and flow into Jira, Linear, ServiceNow and Azure DevOps. Nova pentests start at €1,250 per test excluding VAT, with bundles available, and Atlas is priced by the number of external assets, by quote. Hadrian says it serves more than 300 enterprises and raised a $40 million Series B.
Why organizations look for Hadrian alternatives
Hadrian does a lot well, but teams usually start looking elsewhere for one of three reasons.
1. It looks at what is exposed, not at your code. Atlas covers what a company exposes on the internet, and Nova tests one application from the outside. Hadrian does not describe a code audit, SAST, dependency, secrets or IaC scanning, white-box testing or pull request review, so flaws in code are found only once they are deployed and reachable.
2. Continuous coverage is priced by quote. Atlas is priced by total asset count with no published figures, and leaked-credential detection and M&A assessments are paid add-ons. Nova pentests start at €1,250 each, so testing several applications or every release adds up.
3. It is built for larger security teams. Hadrian describes its customers as security operations teams and CISOs at medium and large enterprises. It runs only from the cloud, with no self-hosted option, and findings come with remediation guidance rather than a patch.
Top 5 Hadrian 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 Hadrian, 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 Hadrian alternative
- It reads your code as well as testing your live application. Code audits and the free SAST suite find flaws in source code, and white-box pentests combine source access with live confirmation, so issues are caught before they reach the internet.
- Its prices are published. The Basic plan is free with no card required, Pro starts at $40 a month, and the price of each code audit is shown before it starts.
- 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, fix verification tests the patched revision before you deploy it, and AISafe can run on your own infrastructure.
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 Pentest-Tools.com
Pentest-Tools.com is a cloud platform for vulnerability scanning and penetration testing of web apps, APIs, networks and cloud. Its AI Pentests, run by the in-house Specter engine, test a deployed web application in black- or grey-box mode and validate each finding with controlled exploitation.
Scanning plans are priced per asset, from $96 a month on NetScan, $140 on AppScan and $190 on Exploit, and AI Pentests are a one-time payment per application, with 2 free retests.
Key features
- Website, API, network and cloud vulnerability scanners
- AI Pentests of a deployed web application, black- or grey-box
- Requests, payloads, screenshots and replay steps for each AI Pentest finding

Ideal for: Internal security teams, consultants and MSPs that want a broad scanning toolkit with AI pentests of web apps on demand.
#5 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.
How to choose the right Hadrian 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 Hadrian to AISafe Labs
Hadrian is a strong choice for enterprises that want their external attack surface watched continuously, with pentests of key applications on demand. If you also want your code tested with source access, every pull request reviewed and fixes verified, at a published price, AISafe Labs covers that in one platform.
