Autonomous pentesting across every scope you own. Web, API, network, and AI, internal and external. Run it on demand or continuously, and configure exactly how it runs.
VLKN is running against real production targets right now, finding validated, critical vulnerabilities that matter.
## why vlkn
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]
No scheduling queue and no kickoff lag. Scope the target and run, instead of waiting for a slot to open up. Teams use it to clear a backlog their bench cannot get to, and providers use it to take on work they would otherwise turn down.
[02]
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]
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.
## for providers
Run your pentest service on a platform you control. Use individual modules or the complete autonomous workflow, choose qualified models and supported infrastructure, and keep your methodology, expert approval, brand, pricing, and client relationships. Add capacity to existing engagements and expand into continuous testing.
## why it's free
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 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.

VLKN does not rely on a model remembering what to test. Its orchestration enforces discovery, shared context, endpoint-by-attack-type testing, validation, and reporting. Operate individual modules or run the complete workflow. Model choice and deployment are configurable without rebuilding the testing system.
[01]
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]
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]
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]
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]
Ninety-plus specialized modules span discovery, testing, validation, and reporting. Run the modules your engagement needs or orchestrate the complete workflow, with shared context across stages. Coverage is built into the execution structure, not left to a model's memory.
[06]
Every finding is independently validated before it reaches the report. No scanner noise, no theoretical risk. Just real, reproducible vulnerabilities.
[07]
Plans, iterates, exploits, and re-plans without human intervention. Modular agents coordinate across discovery, testing, validation, and reporting.
[08]
Active threat-actor modeling informs every engagement. Testing is tailored to the specific scope, context, and adversary profile, not generic checklists.
[09]
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
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.
