Real-Time Visibility, Reduced Risk

Identify vulnerabilities as soon as they appear in your environment, drastically shortening the time between exposure and remediation.

Enhanced Quality & Greater Accuracy

Combining human expertise with AI-enabled tools to consistently identify more vulnerabilities than traditional manual testing, whilst reducing the risk of human error.

Cost Efficiency

Avoid the "fire drill" costs and massive remediation efforts associated with discovering a year's worth of bugs all at once.

Compliance & Assurance

Maintain a constant state of readiness for audits and regulatory requirements.

Introducing PenX

PenX replaces one-off testing with continuous assurance. Traditional penetration testing was designed for a slower world. PenX was built for how attackers operate today.

PenX is Onecom’s continuous security testing service. It runs automated attack simulations against your live environment, every day, adapting as your infrastructure changes.

Security testing becomes a background process, not a disruptive event.

How PenX works

Define scope once

Traditional penetration testing treats scoping as a fixed, manual exercise that has to be repeated every time an environment changes.PenX takes a different approach. Scoping is established upfront, then scales and evolves as customers add new domains, IPs, or services. As environments grow or change, PenX adapts without the need for repeated scoping exercises or administrative restarts. Whether a customer has one domain or thousands, PenX scales to match their exact environment, keeping security testing aligned with how the business actually operates.

Continuous testing begins

Unlike the "snapshot" approach of annual tests that quickly become outdated, PenX runs ongoing assessments. The platform is designed to be adaptive; if your team spins up a new cloud instance or modifies a service, the system detects the change and adjusts its testing parameters automatically.

AI-driven discovery and simulation

Instead of just scanning for a list of known "bugs," the platform uses AI to map out attack paths. This means it looks at how an attacker might chain multiple minor issues together to reach your sensitive data, focusing on real-world exploitability rather than just theoretical vulnerabilities.

Human verification where it matters

One of the biggest complaints about automated tools is "false positives" (fake alarms). PenX includes a human-in-the-loop layer where experts confirm the relevance of findings. This ensures your developers only spend time fixing real, verified threats without the process losing the speed of automation.

Clear, evolving reporting

Most pentest reports are static PDFs that sit in a drawer and lose value every day. PenX provides reports that evolve alongside your risk profile. This gives leadership a "live" dashboard of their security posture, showing what is protected right now rather than what was safe six months ago.

AI plus human expertise

Automation at scale. Human judgement where it counts.

PenX doesn’t replace human expertise.
It removes the bottlenecks that make traditional testing slow and expensive.

AI handles continuous discovery and attack simulation.
Humans provide validation, prioritisation, and confidence when it matters most.

The result: coverage without fatigue, insight without delay.
