Highly adaptative cybersecurity services: assessment, remediation, consulting, managed and advisory

Our penetration testing and cybersecurity services are all about creating a safer online environment for your business. A lack of strong, thoroughly tested, and dependable security measures can leave businesses and other organisations vulnerable to malicious attacks which may snowball into revenue and customer loss — two afflictions it may be difficult to recover from without significant resource and time investment.

Our experienced teams of cybersecurity professionals are experts in locating and reporting potential security risks and vulnerabilities in applications of all kinds. With years of cumulative experience in the cybersecurity profession, they know exactly what to look for when it comes to pushing the boundaries of your systems’ security.

Industry-Leading Penetration Testing

Penetration testing involves simulating an attack to assess the security of a system. There are three types of testing: black box, grey box, and white box. Cyrex offers all three testing modes, allowing organizations to choose the level of access and information they want the tester to have about their system. Black box testing offers an outsider’s perspective, grey box testing is more targeted, and white box testing provides the most comprehensive assessment.

Pair hacking... because two minds are always better than one

At Cyrex, we’re passionate about staying ahead of the curve when it comes to cybersecurity testing. One of the key methodologies that sets us apart is pair hacking. Our team of security engineers work in pairs or groups, emulating the techniques used by black hat hacker collectives to ensure that we’re thoroughly testing the security of our clients’ systems.

What makes pair hacking so effective is the collaboration and communication it fosters among our team members. Each engineer brings their unique perspective and skill set to the table, allowing us to identify and verify vulnerabilities and injection points that might otherwise go unnoticed. With this method, we’re able to ensure that every aspect of the system is secure.

Our workflow

Passive Phase Reconnaissance

This is where we get to know your application or software. Our teams determine the scope of your project by examining the target system, its architecture, programming languages, and functionalities.

Active Phase Target Penetration

The real fun starts in this phase. Here, we do a deep dive with a full, manual penetration test of the target system based on our reconnaissance and previous findings. Fun fact: this process can account for up to 80% of the entire penetration testing cycle!

Reporting Debrief & Next Steps

Once the full testing cycle has been completed, we deliver extensive, no-holes-barred reports on all system vulnerabilities, from small insertion points to major security issues. With this, we can provide creative best practice solutions that work with your workflows and processes. We also outline fully the potential risks of each issue and how a malicious agent could exploit them.
