Cybersecurity Services
Comprehensive cybersecurity for South African businesses — from endpoint to perimeter.
ROI Technologies delivers end-to-end cybersecurity services including EDR/XDR endpoint protection, vulnerability scanning, network security and compliance. We support SentinelOne and Sophos Intercept X for endpoint protection.
Does This Sound Familiar?
Cybersecurity has stopped being an IT issue and become a business survival issue. These are the concerns we hear most from South African businesses:
- You've seen the headlines about ransomware shutting businesses down — and you're not confident yours would survive an attack.
- A big client or enterprise partner is now demanding proof that your business is secure before they'll keep working with you.
- You know most attacks start with email and staff mistakes, but you're not sure your people are protected.
- You have security products in place, but no one is actively watching for threats day and night.
- You're worried about POPIA — the fines are real and you're not sure you could prove your 'reasonable security measures'.
- You don't have dedicated security staff, and you know that makes you an easier target.

Real Security Is Layered — Not a Single Product
No single tool stops every threat. The businesses that get breached usually had 'security' — just not in depth. We protect you across every layer an attacker might target:
Endpoint protection (EDR/XDR)
SentinelOne detects and automatically stops ransomware and malware on every device — including remote workers' laptops — before it can spread.
Network & email threat detection
Darktrace uses AI to spot unusual behaviour across your network, email and cloud — catching threats that slip past traditional tools, including compromised accounts and business email compromise.
Firewall & perimeter security
Fortinet and Sophos next-generation firewalls, properly configured and managed, to control what gets in and out of your network.
Secure configuration & hardening
CIS benchmark assessments make sure your systems are actually configured to recognised security standards — because misconfiguration, not missing tools, is how most attacks succeed.
Your people
KnowBe4 security awareness training turns your staff from your biggest vulnerability into your first line of defence, with phishing simulations and ongoing education.
Why Businesses Choose ROI Technologies for Cybersecurity
Most small IT providers can bolt on antivirus and call it security. Here's what makes us different:
A complete layered defence, not a single product
We bring enterprise-grade capability most small providers simply can't — SentinelOne, Darktrace, Fortinet, Sophos, CIS assessments and KnowBe4 training — working together as one defence, not a random collection of tools.
We help you prove your security to clients
When an enterprise client or insurer demands evidence of your security posture, we give you documented proof — CIS assessment reports, configuration evidence and a clear security roadmap — so you keep the contract instead of losing it.
Local and Randburg-based
We're based in Randburg and genuinely reachable — real people who know your business, our directors included. No faceless call centre, no ticket black-hole.
Proactive monitoring, not just tools
Security products only help if someone is watching. We monitor, patch and respond continuously — stopping threats before they become incidents rather than reacting after the damage is done.
Frequently asked questions
How do I protect my business from ransomware?
Ransomware protection is layered, not a single product. It starts with endpoint detection and response (EDR) to stop malware on every device, tested and immutable backups so you can recover without paying, email security to block the phishing that delivers most ransomware, staff awareness training, and proactive monitoring to catch an attack early. We assess where your gaps are and close them across all these layers.
A client is asking us to prove our security — how do we do that?
This is increasingly common — under POPIA, enterprises are legally responsible when a supplier is breached, so they now audit their suppliers' security. We help you produce the evidence they want: a CIS benchmark assessment of your environment, documented security controls, and a clear remediation roadmap. Being able to demonstrate a strong security posture is now a competitive advantage in enterprise procurement.
What does POPIA require for cybersecurity?
POPIA requires you to take 'appropriate, reasonable technical and organisational measures' to protect personal information — and critically, to be able to demonstrate them, not just claim them. That means real controls like access management, encryption, secure configuration, staff training and incident response, backed by documentation. Fines for serious violations can reach R10 million. We help you put those measures in place and prove them.
We're a small business — are we really a target?
Yes — more than large firms, in fact. Research shows South African SMEs are targeted significantly more per user than big companies, because attackers know smaller businesses often lack dedicated security staff, have untested backups, and are more likely to pay a ransom. You don't have to be a big company to be worth attacking; you just have to be reachable.
What's included in managed cybersecurity?
Our managed cybersecurity brings together endpoint protection (SentinelOne), AI network and email threat detection (Darktrace), managed firewalls (Fortinet and Sophos), CIS security assessments, and staff awareness training (KnowBe4) — all monitored and maintained proactively. The exact mix depends on your environment and risk, which we scope in a free assessment.
How much do cybersecurity services cost?
It depends on the size and complexity of your environment and the level of protection you need. Rather than guess, book a free security assessment — we'll review your current posture, identify your gaps, and give you a clear, no-obligation proposal.
