Offensive security that reflects real attackers
Red Team operations, penetration testing and offensive security advisory for organizations that want to know how they will actually be breached.
No assembly-line staffing model. The same senior expert scopes, executes and debriefs the work.
Findings are prioritized by business impact, exploitability and leadership relevance, not just raw severity.
Every reported vulnerability is real and genuinely exploitable, confirmed by hand, not just flagged by a scanner.
Six service lines covering the full offensive security lifecycle, from technical testing and Red Team operations to legal expert opinions and executive education.
Realistic adversary simulation designed to answer one question: what would a real attacker achieve in your environment? We emulate modern threat actors to test detection, response, and decision-making — not just technical controls.
Targeted, impact-driven penetration testing focused on real attack paths and meaningful findings, not compliance checklists and automated scans.
Security research and threat intelligence focused on emerging attacker techniques, tooling and trends, so your defences are built around how adversaries actually operate today, not how they operated last year.
Independent, senior-level security advisory to help organisations prioritise risk, define security strategy, and communicate clearly at executive and board level, without the cost of a full-time hire.
Independent technical expert reports for civil and criminal proceedings. As an officially licensed Perito Judicial in Spain — registered and numbered by the competent authority — I provide court-admissible expert opinions on cybersecurity incidents, data breaches, digital fraud and related matters.
Tailored cyber training and executive briefings for companies, leadership teams and public institutions, with practical workshops and keynote talks based on real attacker tradecraft.
Every engagement follows a structured timeline with explicit decision points and executive-ready output.
Business objectives, threat model, legal boundaries and success criteria aligned with your leadership and technical teams.
Hands-on adversary emulation or targeted testing performed by senior practitioners using real-world tradecraft.
Technical findings translated into board-level risk language and an actionable remediation sequence.
Validation of corrective actions and final security posture review to ensure risk reduction is measurable.

A healthcare technology company engaged Triskel Security to assess customer-facing web applications and APIs handling patient workflows, sensitive healthcare data and production authentication flows.
The assessment covered web and API security, authentication, authorization and data exposure. 3-week engagement. 14 security issues identified. 3 high-risk findings. Patient PII exposure, privilege escalation and token-based access weaknesses uncovered.
A critical infrastructure operator engaged Triskel Security to perform a black-box Red Team assessment of its external attack surface, including corporate assets, cloud services, exposed portals, supplier exposure and potential OT/ICS systems.
0 alerts triggered. All main goals achieved. Corporate and OT attack paths identified. Exposed administrative interfaces discovered. Leaked credentials and third-party data exposure mapped. Prioritized remediation plan delivered.
A provider of industrial monitoring technology engaged Triskel Security to assess a gateway device, its remote administration portal and the server used to proxy customer gateway traffic.
Hardware, web and network scope. 8 security issues identified. Remote gateway compromise paths found. Configuration-change and disruption scenarios validated. Authentication, SSH and outdated-service hardening reviewed. Gateway management architecture recommendations provided.
Organizations
Most organizations learn where they are exposed when an attacker finds the gap first. Triskel runs controlled, realistic attack simulations so you can identify the same weaknesses earlier, prioritize them correctly and close them before they become an incident.
We focus on sectors where a breach has real
consequences — for operations, people, and public trust.
Banks, asset managers and fintech firms face sophisticated, persistent adversaries — from organised crime groups to nation-state actors. Compliance frameworks like PCI DSS and DORA set a floor, not a ceiling.
We simulate the attack chains targeting your trading infrastructure, customer-facing APIs and internal networks — delivering findings that matter to your security team and your board.
Of financial-services firms were hit by ransomware in the past year (Sophos, 2024)
Healthcare organizations handle protected health information (PHI) under strict rules like HIPAA, making pentesting essential to secure electronic health records, telemedicine apps, and medical IoT devices from ransomware and data breaches. These tests simulate real-world attacks to ensure patient privacy and operational continuity.
Of healthcare organizations were hit by ransomware, a four-year high (Sophos, 2024)
Government agencies manage critical infrastructure and citizen data, requiring pentesting to meet standards like FedRAMP and NIST while defending against nation-state threats. It uncovers weaknesses in public-facing portals and internal networks, supporting national security compliance.
Of ransomware attacks on government ended in data being encrypted, up from 76% (Sophos, 2024)
Retail and e-commerce businesses handle high volumes of payment data and customer sessions across web, mobile and point-of-sale. We find the flaws attackers actually exploit, from checkout and API abuse to account takeover and supply-chain integrations, before they turn into fraud and lost trust.

Critical infrastructure operators run blended IT and OT environments where a breach can disrupt physical operations and essential public services. We map attack paths across corporate, cloud, supplier and OT/ICS layers, showing how a determined adversary could reach safety-critical systems and exactly how to stop them.

Manufacturers depend on connected production lines, IoT and complex supplier networks that quietly widen the attack surface. We test the seams between IT, OT and third parties, surfacing the weaknesses that could halt production, enable sabotage or expose intellectual property.
Of intrusions into manufacturers began with an exploited public-facing application (IBM X-Force, 2025)
Software and SaaS companies carry sensitive customer data and production systems exposed through web apps, APIs and cloud. We simulate the attacks that matter most, from account takeover to cloud privilege escalation and tenant isolation flaws, so you can move fast without shipping risk.
