3.5 million unfilled cybersecurity positions worldwide (ISC² 2024). An experienced CISO costs €80,000–€150,000/year. Competent SOC analysts are hard to recruit and harder to retain. The choice: build a limited internal team, or access a complete team with varied expertise and enterprise-grade tools via a provider.

Outsourcing Cybersecurity: Advantages, Risks and How to Choose a Provider
Outsourcing cybersecurity means entrusting all or part of security activities to a specialised provider. Cybersecurity is increasingly specialised, competent profiles are rare and expensive, and threats evolve faster than internal teams can train. For SMEs and mid-market companies, outsourcing is often the most rational strategy to access enterprise-level expertise without bearing the fixed cost.
01
Why outsourcing has become a necessity
02
What you can outsource
Testing and assessment: cybersecurity audit, pentest, code review — episodic services requiring expertise hard to maintain in-house.
Infrastructure security: designing, implementing and maintaining secure cloud and on-premise environments. See our cloud security approach.
Secure development: see our secure development page.
Training: cybersecurity training programmes for all staff.
03
Concrete advantages of outsourcing
Diverse expertise access: a specialist provider exposes teams to dozens of clients, accelerating skills development and emerging attack pattern detection.
Controlled cost: transforms fixed costs (recruitment, training, tools) into variable costs adjustable to needs.
Availability and responsiveness: rapid resource mobilisation during incidents.
Objectivity: external perspective identifies risks internal teams, too close to the system, may no longer see.
04
Risks to anticipate
Loss of internal knowledge: 100% outsourcing without internal competencies creates dangerous dependency. Maintaining an internal security referent is recommended.
Heterogeneous market quality: the provider market is uneven. Look for technical certifications and recognised qualifications.
Confidentiality: a provider accesses sensitive information. Clear contractual clauses (NDA, access management, responsibilities) are essential.
05
How to choose your provider
Verify technical certifications (OSCP, CISSP, CISM). Request client references in your sector. Evaluate deliverable clarity — a good provider can clearly explain what they will do, how, and what results to expect. Be wary of overly standardised offers.
06
Use cases
Law firm (50 people): confidential data, no dedicated IT team. Annual outsourced audit + staff training + incident assistance.
SaaS scale-up (200 people): part-time external CISO + quarterly pentests + DevSecOps coaching.
Industrial mid-market (500 people): internal CISO + specialist external providers for pentest, ISO 27001 audit, training.
Frequently Asked Questions
Is cybersecurity outsourcing suitable for SMEs?
Yes, often the most appropriate solution. SMEs cannot build a complete internal security team. Outsourcing provides enterprise-level expertise at a proportionate cost.
Should internal security competencies be maintained?
Recommended: an internal security referent (even part-time) who manages the provider relationship, understands the stakes and maintains IT system knowledge.
What is a virtual CISO?
A Chief Information Security Officer provided by a third party, typically part-time. Ensures security governance without full-time recruitment costs.
How to evaluate a cybersecurity provider's quality?
Team technical certifications, recognised penetration testing qualifications, verifiable client references, transparency on methods and deliverables.
In summary
Outsourcing cybersecurity is not an abdication of responsibility — it is a strategic decision. It allows organisations to maintain security consistent with current threats without building an internal team that budgets often cannot support.
