What clients say

Toreon was the obvious choice because they’re a renowned cybersecurity company with deep technical knowledge. Thanks to our collaboration with Toreon, my assumptions were validated. We gained some valuable insights and a roadmap to get us started.

Jan Tanghe

IT Team Lead @ Dewaele

The goal was to meet the medical industry's strictest security requirements. Those efforts have resulted in the company receiving ISO 27001 certification for its overall security management.

Georges De Feu

CEO @ Lynxcare

Just like no one wants to leave their front door open, no one wants to make their home technologically accessible to just anyone. That's why Toreon is our go-to partner for making sure our home is secure.

Which Toreon Service Do You Need?

Choose your starting point based on your immediate driver:

Compliance deadline (NIS2, CRA, DORA, ISO 27001) -> Start with Security Strategy & GRC for gap assessment and roadmap.
Need a CISO but cannot hire full-time -> Virtual CISO (1 to 4 days per month, fractional engagement).
Need to validate security before launch or after major changes -> Ethical Hacking (penetration testing, time-boxed offensive engagement).
Building software or connected products -> Secure Development (OWASP SAMM-based, our consultants co-created the framework).
Migrating to or operating in Microsoft 365 / Azure -> Cloud Security (Zero Trust, Identity and Data protection).
Industrial environment or critical processes -> OT Security (process-aware segmentation and monitoring).
Building or deploying AI / LLM systems -> AI Penetration Testing (prompt injection, tool-call manipulation, agent goal-drift).
Designing a new system or feature -> Threat Modeling Workshop (structured risk identification before code is written).

Unsure which fits? Our security architects often combine 2 or 3 services into a single roadmap. Book a 30-minute discovery call.

Frequently Asked Questions

What cybersecurity services does Toreon offer?

Toreon offers 9 cybersecurity service categories: (1) Security Strategy and Governance, Risk and Compliance (GRC), (2) Secure Development and Application Security, (3) Cloud Security (Azure and Microsoft 365 specialism), (4) Security Architecture, (5) Ethical Hacking and Penetration Testing, (6) Operational Technology (OT) Security, (7) Threat Modeling and Workshops, (8) Virtual CISO advisory, (9) AI Penetration Testing for LLM and agentic AI systems. Each service is delivered by senior consultants from our Antwerp headquarters and serves clients across Belgium and the EU.

What is the difference between strategic and technical cybersecurity consulting?

Strategic cybersecurity consulting (delivered by our CISOs and policy makers) focuses on aligning security with business goals: developing security strategy, governance frameworks, risk management programs and compliance with NIS2, CRA, DORA, and ISO 27001. Technical cybersecurity consulting (delivered by our ethical hackers, cloud security experts, application security experts and OT specialists) focuses on implementation: penetration testing, secure architecture, cloud configuration, OT segmentation. Toreon delivers both layers from one team, so strategy and implementation stay coherent.

What is a Virtual CISO and when do I need one?

A Virtual CISO is an experienced Chief Information Security Officer working for your organization on a fractional basis – typically 1 to 4 days per month. You need a Virtual CISO when (1) your organization is below the size that justifies a full-time CISO but still needs board-level security leadership, (2) you are between permanent CISOs and need continuity, (3) you face a specific compliance deadline (NIS2, ISO 27001, DORA), or (4) you need to scale a security program quickly without recruitment lead time. Toreon’s Virtual CISO service blends strategic governance with hands-on program execution.

Can Toreon help with NIS2, CRA, DORA, or ISO 27001 compliance?

Yes. Toreon’s Government Risk Compliance team specializes in EU regulatory compliance. We help with NIS2 Directive (Article 21 risk management measures, incident reporting), the Cyber Resilience Act (CRA – product security obligations for connected products), DORA (financial sector ICT risk management), and ISO 27001 / ISO 42001 certification programs. Engagement formats range from gap assessments and roadmap development through full implementation support and audit-readiness evidence.

How do penetration testing, threat modeling, and ethical hacking differ?

Penetration testing is a time-boxed offensive test that exploits real vulnerabilities to demonstrate impact. Threat modeling is a structured pre-build analysis that identifies risks before code is written, using frameworks like STRIDE and MAESTRO. Ethical hacking is the practice (and certification standard, CEH) of finding vulnerabilities ethically. Toreon’s services use all three: threat modeling early in the SDLC, ethical hacking and penetration testing for validation. Together they form a complete offensive-defensive program rather than a single point-in-time test.

What is OWASP SAMM and why does Toreon use it?

OWASP SAMM (Software Assurance Maturity Model) is a framework for assessing and improving an organization’s software security maturity. Toreon consultants co-created SAMM at OWASP and continue to contribute to its development. We use SAMM as the backbone of our Secure Development engagements because it provides a measurable, practitioner-validated path from ad-hoc security to optimized programs. Clients benefit from working directly with the framework’s authors.

Who are Toreon's typical clients?

Toreon serves enterprises in regulated and security-critical sectors: financial services (banking, insurance), healthcare and hospitals, medical technology and life sciences, automotive and manufacturing, software builders, HR service providers, and public sector. Our clients range from mid-market enterprises (250-2,000 employees) to large multinationals headquartered in Belgium or with significant EU operations. Sector-specific case studies are available on our Client Stories page.
