vlkn:~$ pentest --target=production

Human-grade pentesting.
Machine scale.

A real pentest, on demand. Validated findings across web apps, APIs, networks, and AI. Not scanner noise, no scheduling queue, no weeks of waiting.

live now

VLKN is running against real production targets right now, finding validated, critical vulnerabilities that matter.

CRITICAL Authenticated IDOR to full account takeover

## why vlkn

The reliability of a pentest. The speed of software.

Manual pentests are trusted but slow to schedule and expensive to repeat. Scanners are instant but noisy and shallow. VLKN gives you a real pentest you can start on demand and run as often as you ship.

[01]

Start on demand

No scheduling queue, no kickoff lag, no services bottleneck. Scope the target and run, instead of waiting weeks for a manual engagement to begin.

[02]

Validated, not noise

Every finding is independently proven and reproducible before it reaches the report. No scanner output running 80 percent false positives, no theoretical risk. Just real, exploitable vulnerabilities.

[03]

Test as often as you ship

Run pentest-grade testing for a compliance deadline, a customer security review, a release gate, or continuous assurance. Repeat it as often as your product changes.

## why it's free

Security that moves everyone forward.

VLKN exists to help teams find more, cover more, and do more. Good security and effective pentesting have always sat behind the biggest budgets, and what we built is too useful, and security matters too much, to leave it there. So now any organization can run a real, human-grade pentest, free, on a web app, API, or network range, on compute and models we built ourselves. Attackers feed on the orgs that never get tested, and a stronger ecosystem is better for everyone in it, your organization included.

## under the hood

Not another AI wrapper.

Most AI pentesting tools are a prompt on top of someone else's frontier model, and frontier bills only move one direction lately. VLKN is built differently, and it is why the findings hold up, the costs stay low, and the deployment options exist at all.

[01]

Custom fine-tuned models

Not an API wrapper. We fine-tune bleeding-edge open-weight models to think and act like real penetration testers. Capabilities off-the-shelf tools cannot match, at a fraction of the compute cost.

[02]

Visual attack-surface mapping

Far more than a spider. Vision-driven agents read rendered pages the way a person does, clicking, typing, and navigating through the modals, dashboards, and SPA state that crawlers never reach. You can only test what you can see, so that is where we put the effort.

[03]

Persistent attack context

Every module writes to shared memory: objects, routes, parameters, credentials, flows, and evidence. What the browser agent finds, the API module uses. What one credential proves, cross-account testing exploits. The engagement gets smarter as it runs, instead of every module starting from zero.

[04]

Authorization and business logic

VLKN logs in as multiple users across different roles, then tests what each one can actually reach: IDOR and BOLA, cross-account access, mass assignment, race conditions, password reset and OAuth flows. Signature matching cannot find these. Understanding the application can.

[05]

Modular by vulnerability class

Ninety-plus specialized modules across the engagement lifecycle, and every vulnerability class gets its own frame of focus. Nothing loses context, nothing gets skipped. Coverage is the design, not a side effect.

[06]

Proprietary validation

Every finding is independently validated before it reaches the report. No scanner noise, no theoretical risk. Just real, reproducible vulnerabilities.

[07]

Autonomous orchestration

Plans, iterates, exploits, and re-plans without human intervention. Modular agents coordinate across discovery, testing, validation, and reporting.

[08]

Threat-aware testing

Active threat-actor modeling informs every engagement. Testing is tailored to the specific scope, context, and adversary profile, not generic checklists.

[09]

Deploy anywhere

Cloud when you want speed. Customer-controlled, on-prem, or fully airgapped when you need sovereignty. Because we own the models and the stack, VLKN runs on a rig that pulls 110v out of the wall, anywhere in the world, reaching sensitive and regulated environments that API-dependent tools cannot.

## team

Built in the trenches, not the lab.

VLKN is built by career offensive security practitioners: hackers, pentesters, and operators who have spent years running real engagements, leading delivery teams, and shipping security platforms at scale.

We are not theorizing about what good pentesting looks like. We have done it, led it, and built the processes behind it. That experience is baked into every layer of the product.

## faq

Questions, answered.

What is VLKN.ai?
VLKN is an autonomous, AI-driven penetration testing platform. It thinks and acts like a real pentester, discovering attack surfaces, testing for vulnerabilities, validating findings, and delivering actionable reports, all without a human in the loop.
How quickly can I get results?
There is no scheduling queue or kickoff lag. Once a target is scoped, VLKN starts testing immediately and delivers a validated report in a fraction of the time of a traditional manual engagement. You can re-run it whenever your product or environment changes.
How is this different from a vulnerability scanner?
Scanners produce noise, typically 80 percent or more false positives, and they cannot find contextual vulnerabilities like IDORs, broken authentication flows, or chained exploitation paths. VLKN reasons about the target the way a human attacker would, and every finding is independently validated before it reaches the report.
How is this different from other AI pentesting tools?
Most AI pentesting tools are built on off-the-shelf frontier models like GPT, Claude, or Gemini. VLKN uses custom, fine-tuned open-weight models, which means better performance on offensive security tasks, deeper IP, lower compute cost, and the ability to deploy on-prem or airgapped where API-dependent tools simply cannot go.
Can it run on-prem or in airgapped environments?
Yes. VLKN is designed to run on a local appliance, making it deployable in sensitive, regulated, or airgapped environments, including government, defense, and regulated enterprise use cases that API-based competitors cannot address.
What does VLKN test for?
Ninety-plus specialized modules across the engagement lifecycle, spanning web applications, APIs, networks, and AI systems. Authenticated and unauthenticated testing, session and auth handling, authorization and business logic flaws, and AI and chatbot-specific testing. Hundreds of individual vulnerability types in total, and growing.
Does it replace human pentesters?
It scales what human pentesters do. VLKN handles discovery, testing, validation, and reporting autonomously, freeing expert human testers to focus on the highest-value work. Think of it as every security team having a world-class red teamer on demand, around the clock.
Is it safe to run against production systems?
As safe as a human pentester testing production, which is the honest bar. Every real test carries some risk. VLKN is bounded the way a good engagement is bounded: configurable aggression levels, exploitation gates, post-exploitation controls, and degradation detection.
Who is VLKN for?
Startups that need trusted pentest results for SOC 2, a customer security review, or a compliance deadline. AppSec, DevSecOps, and security engineering teams that need continuous, high-signal testing without the cost and delay of traditional engagements. And organizations with sensitive or regulated environments where cloud-based tools are not an option.
