Few words from our CEO

I believe that people all over the world deserve to be exceptional. We believe that people everywhere deserve the exceptional. That’s why, since our founding, our mission has been to help companies and peoples and ensuring security in the field of cybersecurity. Cyber Hazard, which I founded in 2015, started out providing web application penetration testing, vulnerability scanning as a service, and social engineering. To further help our clients scale and meet the changing demands of their end users, Cyber Hazard evolved to provide a wide range of testing solutions for websites, servers, networks, connected devices and more.

Why choose us

Why do clients choose us?

No two tests are the same, we work closely with our clients to fully understand their goals, the services under review and any operational considerations before we start. From this, we can provide an accurate test scope, making recommendations to ensure you get the best possible results, as well as value for money.

Cyber Hazard Ltd has been helping to protect organisations for over 7 years and our team of cyber security consultants come from a diverse range of backgrounds, have years of proven experience and a depth of expertise.

Our job doesn’t finish on the delivery of a report, your test consultant will be available after the test to explain any aspect of the report, as well as provide remediation support to internal teams and/or external suppliers.

A project manager is assigned to each client to oversee your project. Whether you require assurances around a new application launch, repeat testing of legacy systems, testing of new functionality or need a combination of services throughout the year, our team are on hand to create a bespoke plan of testing.

Our in-depth, tailored reporting provide clients with a managerial overview of findings, a full technical review of the vulnerabilities found and our remediation advice. We can also provide in-test notifications, initial finding summaries, and integrate into internal ticketing systems where required.

We’re here to support our client’s security improvement efforts, not just during a test but in the long term. We recomend clients to contact us outside of testing and will provide security recommendations and advice free of charge wherever possible.

Oliver has performed several penetration tests for our customers, mostly in the financial sector and public administration. The tests were performed professionally, thanks to which we were able to identify vulnerabilities and then adequately secure the systems according to the recommendations.
