Defence and strategy for those who cannot take risks

Fifteen cybersecurity fronts led by specialists, grouped by the nature of the work. AI accelerates recon, analysis and reporting; the critical judgement is always human. Every engagement starts under NDA.

Offensive

04

Think like the adversary and prove, in practice, what is actually exploitable. We find the real attack path before anyone uses it against you.

  • S01 · Offensive

    Penetration Testing

    We attack your systems like a real intruder to find and prove exploitable vulnerabilities before anyone else does. Web, API, Mobile, Infra, Cloud, IoT/OT and Wireless.

  • S02 · Offensive

    Red Team

    A full attack simulation — digital, human and physical — against a defined objective, testing people, processes and technology.

  • S03 · Offensive

    Adversary Emulation (APT)

    We replicate the documented tactics of a real attack group relevant to your sector, to validate your defences specifically against it.

  • S04 · Offensive

    Reverse Engineering & Malware

    We dissect a binary, malware or firmware to understand what it does, extract indicators and generate detection rules.

Defensive

03

Monitor, hunt and respond. When something gets past the controls, the goal is to see it first, contain it fast and come back online safely.

  • S05 · Defensive

    DFIR — Incident Response

    When the incident hits: we contain, investigate, eradicate and recover. Full regulatory support for breach notification under the applicable data-protection law.

  • S06 · Defensive

    24/7 SOC & MDR

    Threat monitoring and response 24/7/365, with AI handling triage (L1/L2) and senior analysts on critical response.

  • S07 · Defensive

    Proactive Threat Hunting

    Active hunting for threats that already slipped past your controls — we assume something got in and go looking for the evidence.

Hybrid

01

Attack and defence at the same table. What the offensive team discovers becomes detection and playbook for the defensive team — in real time.

  • S08 · Hybrid

    Purple Team

    Attack and defence teams side by side, improving your detection in real time and delivering ready-to-use rules and playbooks.

Strategic

06

Security as a business decision: risk, compliance, culture and leadership. From policy to the boardroom, with data-protection and breach-notification support.

  • S09 · Strategic

    Compliance & Data Protection

    Assessment, implementation and audit readiness. LGPD, ISO 27001, SOC 2 and PCI-DSS — with AI-assisted policy generation.

  • S10 · Strategic

    DevSecOps

    Security built into your development cycle — from design to production, covering SAST, DAST, SCA, IaC and containers.

  • S11 · Strategic

    Tabletop & Crisis Simulations

    Crisis exercises with leadership and key teams to test decision-making and communication under pressure, in a safe environment.

  • S12 · Strategic

    Security Awareness Training

    A year-round awareness programme with AI-simulated phishing, microlearning and gamification to change risky behaviour.

  • S13 · Strategic

    vCISO — CISO as a Service

    A senior security executive on demand, driving strategy, risk management, compliance and the relationship with the board.

  • S14 · Strategic

    M&A Cyber Due Diligence

    Cyber-risk assessment of acquisition targets: past incidents, technical posture, compliance and liabilities.

Assessment

01

Posture assessment with technical depth. Where you stand, what is exposed and what to prioritise — with evidence, not guesswork.

  • S15 · Assessment

    Cloud Security Assessment

    A full security-posture review across AWS, GCP and Azure — IAM, network, data, logging and cloud compliance.

How we run it

Authorisation, evidence and continuity

  1. 01

    Scope before anything

    Nothing runs without authorisation and an agreed rule of engagement. We define target, window and limits in writing.

  2. 02

    Evidence, not guesswork

    Every finding comes with proof of concept, impact and a remediation step — at OSCP/CREST standard.

  3. 03

    From finding to detection

    What the offensive side finds becomes a detection rule on the defensive side (Sigma/KQL/SPL). The loop closes.

Tailored scope

What is the scope of your environment?

From a one-off pentest to a SOC/MDR retainer — we design the right engagement for your risk. NDA before any data.
