FAQ
Your questions, answered.
How much does an engagement cost?
Most of our engagements run between €1,700 and €13,000 excl. VAT depending on scope, with a 15% discount for small businesses, SMBs and non-profits. The online simulator prices your project in two minutes, and the SMB Starter pack is eligible for Bpifrance public co-funding.
What happens after the audit?
We do not stop at the report: oral debrief, action plan prioritized by risk, then, if you wish, remediation support and a retest to verify that the weaknesses are actually closed. HELX remains your cybersecurity partner to carry your security efforts forward.
We are complete beginners: is this for us?
Yes. The SMB Starter pack was designed for a first step: a full assessment, recommendations in plain language and a realistic action plan, with no technical prerequisites on your side.
We are under attack right now. What do we do?
Call us immediately, do not power off the affected machines and isolate them from the network if possible: our team takes over to contain, investigate and regain control.
Why HELX rather than someone else?
A French team that has practiced both offense and defense for ten years: made up exclusively of senior, multi-certified consultants (OSCP, CRTO, CRTP, CHFI, …), recognized expertise, published CVEs and the ability to support you across your entire cybersecurity journey.
