Defentis

Defentis Cyber Security is a South Africa–focused Managed Security Services Provider (MSSP) delivering practical, business-driven cybersecurity solutions for small and mid-sized organisations. We help businesses reduce cyber risk, improve visibility, and respond effectively to modern threats without unnecessary complexity or vendor lock-in.

Our core services include Managed Detection and Response (MDR), 24/7 security monitoring, SOC-as-a-Service, incident response, vulnerability management, ransomware and phishing protection, and endpoint and identity security. We work extensively with Microsoft security technologies, providing Microsoft 365 security hardening, Defender for Business management, conditional access implementation, and secure identity design tailored for real-world business environments. Beyond technical controls, Defentis Cyber Security supports organisations with cybersecurity risk assessments, POPIA compliance guidance, vCISO services, security policy development, and ongoing security advisory. Our approach is aligned with recognised standards and frameworks such as ISO 27001 and NIST, while remaining pragmatic and achievable for growing businesses.

We operate using a remote-first delivery model, supporting clients across South Africa in sectors including finance, retail, healthcare, professional services, and technology.

This model allows us to provide consistent, responsive security services without the overhead and delays of traditional on-site-only providers. What sets Defentis Cyber Security apart is our focus on clarity, accountability, and measurable outcomes.

We prioritise clear communication, actionable reporting, and security controls that directly support business operations. Rather than selling tools alone, we focus on detection, response, and continuous improvement to ensure our clients are prepared for real-world threats.
