Machine Scale.
Human Quality.

Autonomous, AI-driven penetration testing that thinks and acts like a real pentester. Real findings. Zero noise. No human in the loop.

> Live & running
VLKN is in live alpha and running against real production targets — finding validated, critical vulnerabilities that matter.

>> Capabilities

Built in the trenches,
not the lab.

[01] Custom Fine-Tuned Models

Not an API wrapper. We fine-tune bleeding-edge open-source models to think and act like real-world penetration testers — capabilities off-the-shelf tools can't match.

[02] On-Prem & Airgapped

Deployable on a local appliance. Run VLKN in sensitive, regulated, or airgapped environments that cloud-native tools simply cannot reach.

[03] 30+ Vuln Categories

Web apps. APIs. Networks. Auth and unauth. Session management. AI/chatbot testing. Hundreds of vulnerability types across a wide range of attack surfaces.

[04] Proprietary Validation

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

[05] Threat-Aware Testing

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

[06] Autonomous Orchestration

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

>> Team

Built by people
who've lived it.

VLKN is built by career offensive security practitioners — hackers, pentesters, and operators who've spent years in the trenches running real engagements, leading delivery teams, and shipping security platforms at scale.

We're not theorizing about what good pentesting looks like. We've 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 is this different from a vulnerability scanner?
Scanners produce noise — typically 80%+ false positives. They can't 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 top of off-the-shelf frontier models (GPT, Claude, Gemini). VLKN uses custom, fine-tuned open-source models — which means better performance on offensive security tasks, deeper IP, and the ability to deploy on-prem or airgapped where API-dependent tools simply can't 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 can't address.
What does VLKN test for?
30+ vulnerability categories spanning web applications, APIs, and networks — including authenticated and unauthenticated testing, session and auth handling, business logic flaws, and AI/chatbot-specific testing. Hundreds of individual vulnerability types in total.
Does it replace human pentesters?
It scales what human pentesters do. VLKN handles the 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, 24/7.
Is it safe to run against production systems?
Yes. VLKN is bounded by configurable guardrails — including controls for aggression level, post-exploitation behavior, and degradation detection. It's designed to operate safely against real production environments with appropriate scoping.
Who is VLKN for?
AppSec, DevSecOps, and security engineering teams who need continuous, high-signal testing without the cost and delay of traditional pentest engagements — and organizations with sensitive environments where cloud-based tools aren't an option.
