Every business is vulnerable to unseen weaknesses. Whether the organisation operates a data centre in Johannesburg, a branch office in Cape Town, or remote teams across South Africa, each connected device and application represents a potential entry point for attackers. The 2025 Verizon Data Breach Investigations Report (DBIR) shows that exploitation of software and edge-device vulnerabilities continues to rise, particularly in environments where patching and asset visibility are inconsistent. In South Africa, this challenge is magnified by hybrid IT estates that blend legacy on-premise systems with rapidly expanding cloud infrastructure.
Continuous vulnerability management has therefore become a critical pillar of cyber resilience. It enables security teams to identify weaknesses before adversaries do, to prioritise remediation based on real-world risk, and to demonstrate compliance with evolving local regulations such as the Financial Sector Conduct Authority (FSCA) and Prudential Authority Joint Standard 2 of 2024.
The changing threat landscape
Attackers are increasingly opportunistic. Rather than developing bespoke exploits, many rely on publicly known vulnerabilities that remain unpatched on corporate networks. The United States Cybersecurity and Infrastructure Security Agency (CISA) maintains a catalogue of Known Exploited Vulnerabilities (KEV) that is updated daily. Analysts note that exploitation typically begins within days of a vulnerability’s disclosure.
In South Africa, threat actors frequently target internet-facing services such as Virtual Private Network (VPN) gateways, web application servers, and cloud management portals. Misconfigured systems, outdated firmware, and unsupported software versions create accessible attack surfaces that require little sophistication to exploit.
The 2025 DBIR further reports that attacks leveraging unpatched vulnerabilities have grown nearly eightfold since 2020. This trend underlines an uncomfortable reality: the majority of breaches occur not through novel zero-day exploits but through well-known weaknesses that organisations failed to remediate.
Defining Vulnerability Management
Vulnerability management is the continuous process of discovering, assessing, prioritising, and remediating security weaknesses across an organisation’s assets. It is not a once-off audit. It is an ongoing discipline supported by automated scanning, asset inventory, and integrated patch orchestration.
A comprehensive programme typically includes the following stages:
- Asset Discovery – Identifying every device, server, virtual machine, and cloud resource connected to the network.
- Assessment – Scanning for known vulnerabilities using both authenticated and unauthenticated techniques.
- Prioritisation – Ranking findings according to severity, exploitability, and business impact.
- Remediation – Applying patches, configuration changes, or compensating controls.
- Verification and Reporting – Rescanning to confirm closure and providing documented evidence for compliance.
Each stage contributes to measurable reduction of risk exposure and ensures that senior management has quantifiable insight into cyber hygiene.
Why continuous scanning matters
Many organisations still conduct quarterly or annual vulnerability scans to satisfy audit requirements. While these reports provide a snapshot in time, they are quickly outdated. New vulnerabilities emerge daily, and system configurations change continuously due to software updates, staff turnover, and digital transformation initiatives.
Continuous scanning, supported by automated asset discovery, ensures that no device or application remains invisible. It detects new assets as they appear on the network and flags unapproved or “shadow IT” systems before they become liabilities. In remote or hybrid environments where employees connect through home routers and personal devices, this visibility is indispensable.
For critical industries such as finance and energy, regulators now expect ongoing monitoring rather than periodic assessment. The FSCA and Prudential Authority Joint Standard 2 of 2024 explicitly requires institutions to identify and manage vulnerabilities on a continuous basis, reflecting global best practice.
Risk-Based Prioritisation
A large enterprise can identify tens of thousands of vulnerabilities in a single scan. Attempting to patch them all simultaneously is unrealistic. Prioritisation based solely on Common Vulnerability Scoring System (CVSS) ratings is insufficient because it does not account for exploit likelihood or business context.
Modern vulnerability management incorporates two additional data points:
- Exploit Prediction Scoring System (EPSS): Uses machine learning to estimate the probability that a vulnerability will be exploited in the wild within a given timeframe.
- CISA Known Exploited Vulnerabilities (KEV): A curated list of vulnerabilities confirmed to be actively exploited.
By combining CVSS severity, EPSS probability, and KEV confirmation, security teams can focus remediation on the small subset of vulnerabilities most likely to be used against them. When mapped against internal asset criticality—such as systems containing personal information regulated under POPIA—this approach transforms vulnerability management from a technical exercise into a targeted risk-reduction strategy.
Integrating Patch Orchestration and Automation
Once priorities are established, remediation must be both rapid and reliable. Integration between vulnerability scanners, patch-management platforms, and ticketing systems eliminates manual effort and reduces delays.
Automated patch orchestration allows updates to be scheduled, deployed, and verified across diverse operating systems and applications. Exceptions can be documented and tracked for systems where patching is temporarily impractical. In larger environments, integration with configuration-management tools ensures consistent baselines across departments and regions.
Automation also facilitates the generation of compliance evidence. Each remediation cycle produces logs showing when vulnerabilities were identified, who authorised fixes, and when verification was completed—information that auditors and regulators require under the governance provisions of Joint Standard 2 of 2024.
Reporting and Governance
Effective vulnerability management is as much about governance as it is about technology. Executives and boards need concise metrics that translate technical data into business language. Common reporting indicators include:
- Total number of vulnerabilities discovered.
- Percentage of critical vulnerabilities remediated within defined service-level targets.
- Average time to remediate.
- Trend analysis showing improvement or regression over time.
- Residual risk categorised by business unit or system owner.
These reports provide evidence that cybersecurity risk is being actively managed. They also support compliance with POPIA’s requirement for “appropriate, reasonable technical and organisational measures” to protect personal information.
Local Compliance context
South African organisations operate within a maturing regulatory environment:
- POPIA: Requires ongoing risk assessment and prompt breach notification. Demonstrating an active vulnerability-management process provides evidence of due care.
- Cybercrimes Act 19 of 2020: Makes it an offence to negligently fail to secure data or computer systems, which includes ignoring known vulnerabilities.
- Joint Standard 2 of 2024: Applies directly to financial institutions but sets a benchmark for the broader corporate sector. It calls for vulnerability monitoring, timely patching, and board oversight of cyber-resilience frameworks.
Non-compliance can lead to fines, regulatory censure, and reputational harm. Implementing continuous vulnerability management helps organisations prove that they have met the duty of care expected by these laws.
Link to Business Continuity
Beyond regulatory alignment, vulnerability management directly supports operational continuity. Many ransomware incidents begin with exploitation of an unpatched vulnerability. By maintaining a verified patching regime, businesses reduce the likelihood of disruption to critical services such as online banking, retail payment systems, or municipal infrastructure.
For small and medium-sized enterprises (SMEs), the cost of downtime can exceed the cost of the initial breach. Automated vulnerability management lowers this risk by providing early warning and remediation paths that do not depend on large in-house teams.
Quantifying Benefits
An intelligent vulnerability-management programme delivers measurable results:
- Reduced exposure: Continuous scanning ensures that new vulnerabilities are discovered within hours rather than months.
- Shorter remediation cycles: Automation decreases time to patch from weeks to days.
- Improved compliance posture: Audit-ready reports demonstrate adherence to internal policies and external regulations.
- Enhanced stakeholder confidence: Clients, partners, and regulators can see objective proof of resilience.
- Lower incident response costs: Early detection and patching prevent costly breaches that would otherwise demand forensic and legal intervention.
When assessed holistically, the return on investment extends beyond security to include operational efficiency and brand protection.
Implementing Vulnerability Management in South Africa
Practical implementation begins with three fundamentals:
- Asset Visibility: Maintain a live inventory that includes on-premise, remote, and cloud resources.
- Automation: Use tools capable of continuous scanning and integration with patching systems.
- Governance: Establish policies defining remediation timelines, ownership, and escalation paths.
Many South African organisations partner with managed-security providers to deliver these capabilities at scale. Outsourced vulnerability-management services combine technology with specialised expertise, ensuring that scanning, prioritisation, and reporting remain consistent across complex environments.
Unknown weaknesses are the easiest for attackers to exploit. The growth of vulnerability-based breaches demonstrates that visibility and timely remediation are now essential to cyber resilience. Intelligent vulnerability management transforms this challenge into a structured, measurable process that supports both operational security and regulatory compliance.
For South African organisations, adopting continuous, risk-based vulnerability management is no longer optional. It is a prerequisite for protecting data, maintaining trust, and meeting the obligations set by POPIA, the Cybercrimes Act, and Joint Standard 2 of 2024.
