Cybersecurity consulting. A clear plan to protect your business.

I'm Antonio Cebreiro. I help you understand your risks, set priorities and put the measures you need into practice. You work directly with me, from the first assessment to follow-up.

Services

From uncertainty to an action plan

Four ways to help, depending on your situation. We agree the scope and deliverables of each project before starting.

02

Technical security, Microsoft and data

You need to review or implement controls for access, email and information. We start with your environment and the capabilities available in your licences.

The agreed controls are documented, together with validation tests and guidance for operating them.

03

Outsourced CISO

You need someone to coordinate security and follow through on decisions, working with management, IT and suppliers.

We work from a recurring plan and a report covering progress, risks and outstanding decisions.

04

Culture and training

You need your workforce and management to recognise risks and respond. Sessions are tailored to their roles and working situations.

The plan includes sessions, practical exercises and learning assessments to identify where further training would help.

How I work

From the first call to a plan in motion

No blind commitments: every step has a known format and you decide with all the information in front of you.

  1. 01

    First conversation

    A free, no-obligation 30-minute call to understand your situation, clarify what you need and discuss the next step.

  2. 02

    Plan

    If it makes sense to continue, you get a fixed proposal: scope, timeline and price. Priorities ordered by real risk, in a document your management can actually read.

  3. 03

    Ongoing support

    We execute the plan together, at your pace: a one-off project or monthly follow-up, with me at the other end whenever something comes up.

Free tools

From the community, for the community

Part of what I use with my clients is open to everyone: self-assessments and checklists you can use today, with no sign-up and without leaving your data anywhere.
