Frequently asked questions
What companies like yours ask
My company is small. Do I really need professional cybersecurity?
Yes. 88% of SMB breaches involve ransomware (Verizon DBIR 2025): attackers use automation and do not pick targets by size. The free assessment shows exactly what is essential for your size, without overselling.
How much does a professional pentest cost?
Our entry plan, Essential Defense, starts at R$ 2,799, with scope and price fixed before we start. Combining AI with certified specialists cuts cost without cutting depth.
I have no technical team. Will I understand the results?
You will. The executive report is written in business language, with an action plan prioritized by risk and cost. A specialist reviews the results with you, jargon-free.
Do you serve municipalities and public agencies?
Yes. We protect citizen data and critical systems for municipalities and public agencies, with LGPD compliance and documentation suited to public procurement processes.
How long does it take?
The free assessment takes 5 minutes and the report arrives within 24 hours. A full pentest is delivered in business days, with a free re-test included after fixes.
Is my data safe during testing?
Yes. We work under NDA, in agreed windows, and our AI models run locally so no data leaves your environment. Evidence is stored encrypted with chain of custody.
