Frequently asked questions
What does Oxydian offer?
Audits and penetration tests, cybersecurity consulting, and two products: the Oxyscan BOX for continuous auditing and the Oxyscan Valise for auditors and managed IT providers.
What is the difference between a one-off audit and continuous auditing?
A one-off audit is a snapshot at a single point in time. The Oxyscan BOX audits your network continuously, detects new vulnerabilities and measures your progress over time.
Do we need an in-house cybersecurity expert to work with you?
No. Our experts carry out the audit and support you throughout, and our tools are designed to be used without advanced technical skills.
How much does a cybersecurity audit cost?
It depends on the scope: size of your estate, objectives, type of audit. Request a quote, or test your level for free with our Cyberscore.
Does my data remain confidential?
Yes. Everything runs locally, and no data ever leaves your premises.
