Most Common Questions on Cybersecurity Answered:
Can an SME achieve enterprise-level cybersecurity with a limited budget?
Yes, SMEs can achieve enterprise-level cybersecurity by adopting the right operating model. A structured outsourced approach combined with nearshoring provides access to senior expertise and proven security tools while significantly reducing costs. This is exactly Systelium’s specialty: delivering enterprise-grade cybersecurity to SMEs through a pragmatic and cost-effective nearshore model.
What is a CISO Office, and how does it work?
A CISO Office is a comprehensive cybersecurity management framework delivered by a dedicated full-time security team. It goes beyond a single outsourced CISO and includes governance, risk management, regulatory compliance, operational security and incident management. The CISO Office operates as a fully structured internal cybersecurity team, without the cost and complexity of hiring internally.
When should a company outsource its cybersecurity?
A company should outsource its cybersecurity when it lacks: the budget to build a full internal security team, sufficiently continuous needs to justify internal hires, or the expertise required to meet regulatory and security challenges. Outsourcing provides immediate access to a scalable, operational and fully managed cybersecurity framework.
How much does cybersecurity cost for a company of 100 to 1,000 employees?
At Systelium, full cybersecurity management starts from €700 per day, delivered full-time by a complete cybersecurity team covering governance, protection, detection and incident response.

What does cybersecurity management include for an SME or mid-sized company?
Cybersecurity management for SMEs and mid-sized companies includes: cybersecurity governance and strategy, risk assessment and mitigation, regulatory compliance, system and data protection, incident detection and response, red team exercises and penetration testing, strengthening cyber resilience, employee awareness and training, KPI monitoring and continuous improvement. The objective is to deliver end-to-end, resilient cybersecurity aligned with business priorities.
