What does a Penetration Test do?
A Penetration Test will intentionally test the strength of your security controls in the same way a cybercriminal might try to exploit your organisation.
Through controlled and methodical practices, our teams will not only find any weaknesses but will also recommend how to address them in a fully documented process report of our findings. A Penetration Test is a health check of your systems that allows you to fix any discrepancies and ensure your organisation, staff, and customers are protected.
