Why Open Cybersecurity exists.

Lucas, São Paulo

I started Open Cybersecurity because Brazilian scale-ups were paying US-priced consultancies for US-shaped programs. The result: half-translated playbooks, three-week SLA on every Slack message, and audits that surprised everyone.

I'd worked across Big 4 advisory and in-house at a regulated fintech. The pattern was the same: smart engineers stuck in audit prep, founders apologizing to enterprise buyers, and a security program that always lagged the business by a quarter.

Open is the team I wish I'd had, Slack-embedded, AI-drafted, fluent in Portuguese, English, and BACEN. We sit beside customers, not across a table from them. We ship policy like engineers ship code. We pick up the phone when ANPD calls. Alfred is how the work runs.

Values

Four things we do not compromise on.

01

Customer ownership

We hold accountability for outcomes. The certificate, the audit defense, the regulator response.

02

Plain language

No jargon. No "leverage". No 80-page deliverables. Verbs, not nouns.

03

Speed with judgment

Fast does not mean reckless. Every artifact is reviewed by a senior before it ships.

04

Engineer respect

We protect engineer focus. Audit prep is our job, not theirs.
