What CESI does
CESI is a Belgian External Service for Prevention and Protection at Work (SEPPT) founded in 1968 that delivers mandated occupational health, safety, ergonomics, industrial hygiene, and psychosocial risk services to employers across Belgium. As a licensed SEPPT, it provides recurring affiliation services, occupational health surveillance (medical examinations, fitness and return-to-work assessments), risk analysis, fire safety planning, and first-aid training under the Belgian Code du Bien-être au travail. The firm operates a multi-site footprint across Belgium (headquartered in Brussels/Woluwe-Saint-Lambert, with regional consultation and training centers in Liège, Wierde, Louvain-la-Neuve, Mons, Nivelles, Tournai, Libramont, and other cities), serving SMEs (under 200 workers) through a dedicated offering and large enterprises (200+) through multi-disciplinary service bundles.
The group's product surface extends beyond compliance through two wholly-owned sub-brands: One, providing management, leadership, and HR training, and SenseCare, providing burnout prevention, screening (SenseCare Diagnostic médico-psychologique), and support, developed jointly with One. Additional offerings include diagnostic tools such as the Balencio collective stress-resource screener, mindfulness programs, VCA Safety Certificate training delivered in partnership with Maison de la Formation, and digital disconnection advisory. Recent strategic moves include embedding in the Fedris-led permanent burnout support program (April 2024) and aligning with the TRIO reintegration platform (effective February 2025).
CESI generates revenue through three streams: affiliation/membership fees and per-consultation charges for occupational health surveillance (recurring), fee-based consulting engagements on a per-project or retainer basis, and training delivered through classroom, in-company, and e-learning formats with per-participant, course, and certification fees. CESI is structured as a Belgian ASBL (non-profit association) and operates as a sales-led organization with direct employer outreach, content marketing (blog, LinkedIn, YouTube, newsletter), workshops (Ateliers Bien-être), and event participation. Revenue is not publicly disclosed.

CESI competitors and assessment
Company assessmentBroad incumbents
- DNV: Independent assurance and risk management company providing occupational health, safety, and management system training and certification. Comparable to CESI in safety training, certification, and advisory offerings, scaled to a global enterprise customer base.
- SGS: Global testing, inspection and certification giant offering workplace health, safety, and EHS training and advisory services at scale. Comparable to CESI in training, certification and risk management offerings but operates globally with a much broader service portfolio.
- Bureau Veritas: International TIC (testing, inspection, certification) company providing occupational health and safety training, audits, and certification services. Comparable to CESI in its safety/VCA-style training and certification focus, but with much broader international scope.
- Acerta: Belgian HR and social security services provider with an occupational health and well-being arm. Overlaps with CESI in the occupational health and prevention-advisor training space but operates as a broader HR services incumbent rather than a specialist SEPPT.
- TÜV Rheinland: Global testing and certification organization offering occupational health and safety training, including VCA-adjacent safety certifications. Overlaps with CESI's safety training product line but competes only as an international incumbent rather than a Belgium-only SEPPT.
- Securex: Large Belgian HR services group offering payroll, social secretariat, occupational health, and prevention services as part of a much broader portfolio. Competes with CESI in occupational health and well-being services but addresses these via a wider HR-services bundle rather than as a specialist.
Direct peers
- Mensura: Belgian SEPPT offering occupational health surveillance, risk analysis, and workplace wellbeing services under the same legal affiliation framework as CESI. Directly comparable in service portfolio (occupational medicine, safety, ergonomics) and in targeting Belgian employers requiring external prevention support.
- Attentia: Belgian HR and well-being-at-work service provider offering psychosocial risk support, absenteeism management, and prevention services that overlap directly with CESI's large-enterprise and SenseCare offerings. Comparable in target customer (Belgian employers) and in regulatory-driven service positioning.
- Cohezio: Brussels-based Belgian SEPPT (Service Externe) directly comparable to CESI in providing mandated occupational health and prevention services to Brussels and Flemish employers. Operates the same affiliation model across occupational medicine, safety and psychosocial risks.
- IDEWE: One of the largest Belgian External Services for Prevention and Protection at Work (SEPPT), directly competing with CESI for employer affiliations across all five well-being disciplines (safety, occupational medicine, ergonomics, industrial hygiene, psychosocial risks). Operates the same mandated affiliation model and serves the same SME and large-enterprise segments in Belgium.
