Round-the-clock threat monitoring, zero-trust access and POPIA-ready controls from a local team in Somerset West, protecting businesses across Cape Town and the Western Cape.

Cape Town businesses are targeted by the same ransomware, phishing and business email compromise campaigns as companies anywhere in the world. Many are also too small to run their own security team. We fill that gap. Our Security Operations Centre watches your endpoints, network, cloud and Microsoft 365 every hour of every day, and our Somerset West engineers can be on-site with you when a problem needs hands-on attention.
You get one accountable partner for prevention, detection and response, instead of a stack of tools nobody has time to manage.
Every engagement is scoped to your size and risk. Most clients start with a few of these and add more as they grow.
24/7/365 monitoring of endpoints, network, cloud and Microsoft 365, with managed detection and response to contain threats before they spread.
Multi-factor authentication and least-privilege access, so only the right people reach the right systems, from the office or from home.
Hardened Microsoft 365 and Azure configurations, email protection against phishing and impersonation, and secure cloud backup.
Documented controls and audit-ready evidence for POPIA, King IV and ISO 27001 obligations, built on a NIST-compliant security practice.
Tested backup and disaster recovery, so a ransomware attack or failed server is an inconvenience, not a business-ending event.
A fractional Chief Information Security Officer for board reporting, policy and security strategy, at a fraction of the cost of a full-time hire.
Local government bodies with public data, critical services and strict audit requirements.
Public-sector and regulated organisations that must prove compliance, not just claim it.
Professional firms and SMEs across Cape Town that hold client and financial data.
Farms and agri-businesses in the Winelands and beyond, with connected sites and IoT devices to secure.
We review your network, devices, Microsoft 365 and backups, and show you where the real risks are.
A prioritised plan in plain language: what to fix first, what it costs, and what it protects.
We put the controls in place and monitor them around the clock, with regular reports you can take to your board.

No. Our team is based in Somerset West, and we work with businesses across greater Cape Town, including the CBD, the Northern and Southern Suburbs, Stellenbosch, Strand and the Helderberg, as well as clients elsewhere in South Africa.
POPIA requires you to take reasonable technical and organisational measures to protect personal information. We put the controls in place (access management, MFA, monitoring, backup), document them, and give you audit-ready evidence. Our security practice is NIST compliant, and we align with King IV governance expectations.
Our Security Operations Centre is designed to detect and contain threats early. If an incident does happen, we isolate affected systems, investigate what happened, restore from backup and help you meet your POPIA notification duties to the Information Regulator and affected people.
