Uncover Your Vulnerabilities and Strength Your Infrastructure

Traditional penetration testing methods often fail to provide the robust, year-round defence your business requires. The predictable patterns and repetitive formulae can restrict innovative insights, overlook critical areas and lead to formulaic reporting that might miss emerging threats.

At CyberOne, we don’t settle for the status quo. Our penetration testing services continuously evolve to keep pace with the rapidly changing cyber security landscape.

We customise our penetration testing to match your specific business environment, ensuring a comprehensive and up-to-date defence system that truly protects your valuable digital assets.

Holisitic Penetration Testing

Our penetration testing service analyses both internal and external threats to your network, giving you a 360-degree view of your cyber security posture and leaving no stone unturned.

Internal Penetration Testing

Internal Penetration Testing is an essential part of a robust cyber security framework. The process simulates an insider attack, giving us insights into what could potentially be achieved with initial access to your network.

Whether it’s a disgruntled employee or an unintentional action leading to a breach, internal penetration testing uncovers these vulnerabilities. By mimicking these scenarios, our penetration testing services can identify weaknesses within your system, providing a clear path to strengthen your internal defences.

External Penetration Testing

External Penetration Testing is a critical component in safeguarding your company’s digital perimeter. Our penetration testing services simulate attacks to evaluate your security controls and identify vulnerabilities in your internet-facing assets.

We aim to uncover potential weak points before they are exploited by malicious entities. Our penetration testing process provides us with a comprehensive view of your organisation’s cyber security posture from an outsider’s perspective, enabling us to enhance defences against real-world threats.

Penetration testing has moved on. Have you moved with it?

The landscape of cyber threats isn’t what it used to be. With the rise of hybrid working, shifting business infrastructures and advanced threats from nation-state actors, the traditional once-a-year penetration testing simply doesn’t cut it anymore. It’s time for your penetration testing strategy to adapt and evolve.

It’s not just about increasing the frequency or speeding up the process, but also about embracing automation, refining methodologies and aligning more closely with your business needs. Explore our insights and advice in this quick read on how you can step up your penetration testing game.

Penetration Testing Case Study

Key drivers for CyberOne penetration testing

With CyberOne penetration testing, we evaluate your networks, applications, endpoints and users against both internal and the latest external threats. The insights gleaned from our penetration tests enable you to shore up your security strategy and plug any holes in your system.

Assess Your Risk

Risk assessments, complemented by comprehensive penetration testing, enable you to stay proactive in identifying and managing potential vulnerabilities. By adopting a continuous assessment strategy, you are taking the essential steps to mitigate risk and ensure maximum protection for your digital assets.

Secure Your Evolving Infrastructure

Whenever you integrate new technologies or expand your organisation, your security profile changes. With Penetration testing, it helps to reveal any potential weak spots or security misalignments that may leave your systems exposed. Stay ahead of the threats and ensure your evolving infrastructure remains well protected.

Determine Improvements, Reduce Risks

Penetration testing consistently identifies areas of weakness in need of remediation. Armed with the insights from the penetration test report, your organisation can determine necessary improvements, shaping a plan to reduce exposure to risks.

Navigating Security Risks in Business Expansion

Inheriting an IT network through business acquisition introduces fresh risks. Comprehensive penetration testing swiftly pinpoints pressing issues that need resolution. Additional security assessments are strongly recommended prior to merging systems or transferring data.

Build a Case for Increased Spending

If you’re aware of issues that need remediation, but struggle to get the sign-off on additional spending, penetration testing offers clear, compelling evidence to bolster your argument. The results help to direct funds towards the most critical issues and serve as a starting point for discussions around other important but less immediate concerns.

Instill Confidence in Clients, Partners and 3rd Parties

Penetration testing fosters trust from current and potential clients. It demonstrates your active efforts to reduce the risk of a breach, using an independent third party to examine your security protocols.

Fulfil Compliance and Regulatory Obligations

For certain industries, penetration testing isn’t optional; it’s a necessity. These penetration tests serve as evidence that you’re actively maintaining a robust cyber security posture and managing potential risks. Not only will this help you stay compliant, but it also assures your stakeholders that their data is being handled with utmost care and security.

Case Study – Elcoin Ltd

In a strategic partnership, Elcoin engaged CyberOne to validate and enhance their cyber security posture. Leveraging our banking sector expertise, CyberOne provided a comprehensive penetration testing service.

This included pre-engagement analysis, vulnerability identification and exploitation, grey box penetration testing and detailed reporting. The outcome was a robust and secure Elcoin, confidently prepared for the evolving challenges of the fintech industry.

Sergejs Svircenkovs, CEO, Elcoin Ltd

“We approached a lot of companies and CyberOne was the only one that fully matched our requirements.

Our account manager helped us pick the most appropriate service and was on hand to support throughout.
