Architecture first
Target-state designs mapped to NIST CSF 2.0 before any tooling decision.
Engineering, not slideware
Every engagement ends in working controls, pipelines and runbooks.
Automation by default
Guardrails, detections and audit evidence delivered as code.
Europe & Brazil
Remote-first delivery from Portugal across the EU and LATAM.
One mission, two pillars
From remote connectivity to cyber resilience — secure the infrastructure that keeps the world connected.
ASNC works where networks and security meet: defending the enterprise and cloud estate, and engineering the satellite links that reach the places terrestrial networks cannot.
Satellite Communications — GEO & Ku-band
GEO and Ku-band VSAT architecture, deployment and operations for remote, offshore and Amazon environments — resilient connectivity integrated with enterprise and OT networks.

Executive leadership
Fabio Vieira, Founder & Principal Consultant
Senior cybersecurity architect and security technology leader with three decades in IT across identity, cloud security, networks, telecommunications and critical infrastructure. Fabio focuses on IAM/PAM, identity governance, least privilege and Zero Trust, turning business and regulatory requirements into security architectures and practical implementation roadmaps.
His hands-on approach combines hybrid and multi-cloud security with Python, Ansible, Terraform and API automation, including security foundations for AI agents and non-human identities. The experience below reflects his career history; it is not a list of ASNC client engagements.
Credentials
- CISSP
- ISO 27001
- MSc
Satellite communications at scale
More than 600 VSAT terminals supporting offshore and Amazon operations, on GEO Ku-band satellite networks he helped design and operate.
Satellite-enabled telemedicine
Connectivity programmes that brought telemedicine services to remote communities over satellite links.
SCADA & industrial automation
Operational technology for SCADA and industrial automation environments, where availability and safety are non-negotiable.
Power transmission & renewables
Network and communications engineering for power transmission infrastructure and renewable energy projects.
Why ASNC
Architects who ship the controls they design
Our differentiators are how we work, not claims we cannot evidence.
Security architecture depth
Reference architectures, threat models and control mappings produced by architects who then implement them — not handed to a separate delivery team.
Security engineering discipline
Controls shipped through version control, CI pipelines and peer review, so security changes are testable and reversible.
Automation and controls-as-code
Guardrails, detection content and compliance evidence generated continuously instead of assembled before each audit.
Enterprise and regulated context
Designed for organisations with change boards, auditors and legacy estates — sequencing that survives real operational constraints.
Capabilities
Advisory that ends in working controls
Every engagement produces artefacts your teams can run: reference architectures, pipelines, playbooks and evidence.
Threat-informed defence
MITRE ATT&CK coverage modelling, purple-team validation and detection engineering across cloud and network telemetry.
Compliance engineering
One control set that can be mapped to ISO 27001, NIST CSF, PCI DSS, DORA and NIS2, with evidence produced by pipelines.
Security automation
Infrastructure guardrails, automated remediation and response playbooks that reduce manual toil on the security team.
Managed and co-managed security
Ongoing control validation, posture review and co-managed detection alongside your existing operations.
Compliance
Framework alignment, engineered into controls
ASNC helps organisations align with the frameworks and regulations below. We design and implement supporting controls — we do not issue certifications or guarantee compliance outcomes.
ISO 27001
ISMS design and control implementation to support certification readiness.
NIST CSF
Framework-aligned target architectures and control gap analysis.
PCI DSS
Scope reduction, customised approach and continuous validation support.
DORA
ICT risk, resilience testing and third-party register operationalisation.
NIS2
Essential-entity scoping, governance duties and incident reporting.
Start with an assessment, not a proposal
A scoped architecture and control review gives you a prioritised roadmap you can act on — with or without us.
