Most businesses tick the security box the same way: antivirus installed, firewall running, staff trained once a year. Yet breaches keep happening. The uncomfortable truth is that your security setup might look solid on paper, but you won’t know if it actually works until it’s tested under real-world conditions.
Here’s what separates resilient organisations from reactive ones: They invite professional attackers to find their weaknesses first. South African businesses face a growing threat landscape, from ransomware syndicates targeting local enterprises to compliance pressure under POPIA. The stakes are high, and assumptions about security are expensive. This is where penetration testing and red teaming become necessary, two distinct approaches to answering one critical question: Are your defences working, or are they merely present?
“Are your defences working, or are they merely present?“
Penetration testing is a controlled ethical hacking exercise designed to identify vulnerabilities in your systems, applications, or networks. Think of it as a focused security audit where certified professionals attempt to breach specific parts of your IT infrastructure, just as a malicious actor would.
What sets penetration testing apart is its scope-based nature. Rather than testing your entire organisation, pen testers focus on defined systems or assets, such as a web application, network infrastructure, or wireless connections. This targeted approach makes it ideal for organisations that need to validate security controls, meet compliance requirements, or assess new technology deployments.
The process typically follows a structured methodology. Testers begin with reconnaissance, gathering information about the target system. They then move to scanning and vulnerability assessment, identifying potential weaknesses. The exploitation phase involves attempting to leverage these vulnerabilities to demonstrate real-world impact. Finally, testers provide a comprehensive report detailing discovered vulnerabilities, their severity, and actionable recommendations for remediation.
The benefits are tangible: improved security posture, compliance readiness for frameworks such as ISO 27001 and POPIA, reduced risk, and a clear roadmap for strengthening defences. For organisations new to offensive security testing, penetration testing provides an accessible entry point that delivers measurable value.
Red teaming takes security testing to the next level. Rather than focusing on specific systems, red teaming is a comprehensive adversarial simulation that tests your entire organisation including technology, processes, and people.
Where penetration testing asks, “What vulnerabilities exist in this system?“, red teaming asks, “If someone really wanted to get in, could they?”
This goal-oriented approach mirrors real-world attack campaigns. The Red Team selects a high-value target, perhaps your financial database or customer records, and attempts to access it by any means necessary.
The tactics employed are remarkably diverse. A red team engagement might begin with open-source intelligence gathering, scraping public data, social media profiles, or leaked credentials. From there, testers might attempt social engineering attacks, convincing employees to click malicious links or download spoofed documents. If access is gained, they deploy advanced tools to map your network, move laterally through systems, escalate privileges, and attempt data exfiltration, all while avoiding detection.
“Red teaming tests not just your technical controls but your organisation’s ability to detect, respond to, and recover from sophisticated attacks.”
This extended simulation typically runs for weeks or even months, testing not just your technical controls but your organisation’s ability to detect, respond to, and recover from sophisticated attacks. The collaboration between Red Teams (offensive) and Blue Teams (defensive) creates a realistic pressure test of your incident response capabilities, revealing gaps that traditional assessments often miss.
Understanding when to deploy each approach requires clarity on their fundamental differences:
Category | Penetration Testing | Red Teaming |
Objective | Identifies vulnerabilities in specific systems, providing a technical audit of defined assets | Tests overall detection and response capabilities, evaluating organisational resilience against determined adversaries |
Scope | Defined systems or applications (e.g., web portal, network segment) | Entire organisation including physical security, employee awareness, third-party integrations, and incident response procedures |
Duration | Short-term (days to weeks) | Extended (weeks to months) to simulate persistent threat actors |
Outcome | Vulnerability report with patch recommendations and prioritised remediation steps | Realistic attack simulation revealing detection speed, containment effectiveness, escalation procedures, and recovery measures |
When to Use | Routine security validation, compliance-driven assessments, testing new infrastructure | Mature organisations with established security controls wanting to evaluate real-world readiness and train incident response capabilities |
Selecting the right approach depends on your organisation’s security maturity, business objectives, and compliance requirements.
Choose Penetration Testing when you need compliance-driven assessments for POPIA, ISO 27001, or industry-specific regulations, such as the FCA’s Joint Standard 2 (JS2). It’s ideal when testing new infrastructure, applications, or network implementations before they go live. If you want a clear, prioritised list of technical vulnerabilities to address, penetration testing delivers actionable results efficiently. It’s also the appropriate starting point for organisations building their security programme or those without established baseline security controls.
Choose Red Teaming when your organisation already has mature security controls and established monitoring capabilities. If you want to evaluate how quickly your team detects and responds to sophisticated attacks, red teaming provides invaluable insights. It’s particularly valuable for testing business continuity plans under realistic pressure, training your incident response and Blue Team capabilities, and assessing whether your security investments are performing as intended. Organisations handling sensitive data or operating in high-risk sectors benefit significantly from red team exercises that reveal blind spots in defence strategies.
Many organisations adopt a progressive approach, beginning with penetration testing to address technical vulnerabilities, then graduating to red teaming once foundational controls are in place.
At Cyberlogic, we believe offensive security testing isn’t just about finding vulnerabilities; it’s about strengthening your organisation’s entire security posture through expertise, customisation, and partnership.
Our team comprises certified experts with globally recognised credentials and each team member brings over a decade of hands-on experience across diverse industries and organisations of all sizes. This depth of expertise ensures we don’t just run automated scans; we think like attackers, identifying complex vulnerability chains that automated tools miss.

Whether you’re testing customer-facing web applications, evaluating insider threat risks, or simulating ransomware campaigns, our methodology adapts to your unique threat landscape.
Our approach leverages advanced toolsets and methodologies aligned with global standards and industry best practices. We combine automated scanning with manual testing techniques, ensuring comprehensive coverage that reveals both common misconfigurations and sophisticated attack paths.
Beyond testing, we offer a holistic security partnership. Our Red Team collaborates with your internal teams and our Blue and Remediation Teams to prioritise actions, implement fixes, and verify remediation through retesting. We don’t simply deliver a report and disappear; we work alongside you to ensure vulnerabilities are properly addressed and your defences are measurably stronger.
We understand the local compliance landscape, threat environment, and operational challenges facing South African businesses. Our proven track record demonstrates success in helping organisations strengthen cyber resilience, achieve compliance, and build lasting security capabilities.
What is the main difference between penetration testing and red teaming?
Penetration testing focuses on identifying technical vulnerabilities in specific systems or applications, delivering a detailed report of weaknesses to fix. Red teaming simulates comprehensive, goal-oriented attacks against your entire organisation, testing technology, processes, and people to evaluate detection and response capabilities.
How often should a business perform penetration testing?
Most organisations should conduct penetration testing at least annually, with additional tests when deploying new systems, making significant infrastructure changes, or after security incidents. High-risk sectors or those with stringent compliance requirements may benefit from quarterly assessments.
Is red teaming necessary for small and medium-sized businesses?
Red teaming is most valuable for organisations with mature security controls and established monitoring capabilities. Small to medium-sized businesses should typically begin with penetration testing to address foundational vulnerabilities, then consider red teaming once baseline security is established and they need to test real-world resilience.
How long does a typical red team engagement take?
Red team engagements typically run from several weeks to several months, depending on the scope, objectives, and complexity of your environment. Extended duration allows for realistic simulation of persistent threat actors and thorough testing of detection and response capabilities.
Both penetration testing and red teaming are vital components of a strong cyber security posture. They’re not competing approaches but complementary strategies that serve different purposes at different stages of security maturity.
Penetration testing provides the technical foundation, identifying and addressing specific vulnerabilities before they’re exploited. Red teaming elevates your defences, testing whether your organisation can detect and respond to determined adversaries targeting your most valuable assets.
Choosing the right approach depends on your business maturity, security goals, and compliance requirements. Whether you’re starting your offensive security journey or ready to test your defences against sophisticated attack simulations, the time to act is now, before real attackers find the gaps you haven’t yet discovered.
