Automated Patch Management: Stop Chasing Updates
24 November 2025 · 0x1m3 · 6 min read
Every piece of software on your network has vulnerabilities. Vendors release patches to fix them. Your job is to apply those patches before attackers exploit them.
Sounds simple. It is not.
The average enterprise manages hundreds of applications across hundreds of devices. Patches drop on different schedules. Some require restarts. Some break other software. Some get missed entirely. Manual patching is a losing game — and the stakes are your organisation's security.

Why Manual Patching Fails
IT teams that patch manually face the same problems:
Volume. Microsoft alone releases patches on the second Tuesday of every month — sometimes dozens at a time. Add Adobe, Google, Java, Zoom, and every other application in your stack, and the number of updates per month becomes unmanageable.
Inconsistency. Patches get applied to some machines but not others. A technician updates the servers but forgets the branch office workstations. Remote workers skip updates for weeks. One missed device is all an attacker needs.
Timing. Critical security patches need to deploy quickly. But testing, scheduling, and coordinating reboots across a production environment takes time. The window between patch release and exploitation is shrinking — sometimes to hours.
Visibility. Without centralised reporting, nobody knows which devices are patched and which are exposed. Compliance audits become guesswork.
What Gets Patched: The Full Picture
Automated patch management through N-able N-central covers two critical areas:
Microsoft OS Patches
| Patch Class | What It Covers |
|---|---|
| Security Updates | Fixes for vulnerabilities rated critical, important, or moderate |
| Critical Updates | Non-security fixes for stability and reliability |
| Service Packs | Cumulative update rollups |
| Feature Updates | Major Windows version upgrades |
| Driver Updates | Hardware driver patches from Microsoft Update |
| Definition Updates | Antivirus and anti-malware signature updates |
Third-Party Application Patches
N-central automatically patches over 100 third-party applications, including the most commonly exploited software:
| Category | Applications |
|---|---|
| Browsers | Chrome, Firefox, Edge, Opera |
| Productivity | Adobe Reader, LibreOffice, Notepad++ |
| Communication | Zoom, Microsoft Teams, Slack |
| Utilities | 7-Zip, WinRAR, VLC Media Player |
| Runtimes | Java, .NET Framework, Python |
| Security | Various endpoint tools and utilities |
These are the applications attackers target first. Keeping them current eliminates the most common entry points.

How Automated Patching Works
The process is straightforward once configured:
1. Discovery. N-central scans every managed device and builds a complete software inventory. You know exactly what is installed, what version it runs, and whether it is current.
2. Policy creation. You define patch policies per device group. Servers might receive patches on weekends with a mandatory reboot window. Workstations might patch overnight on Wednesdays. Critical security patches can deploy within hours.
3. Testing. Patches deploy to a pilot group first. If no issues arise within the test window, they roll out to production. If a patch causes problems, it gets blocked before reaching your wider environment.
4. Deployment. Patches install silently in the background. Users see a brief notification to reboot — or the reboot schedules itself outside business hours.
5. Reporting. Compliance dashboards show patch status across every device. You see exactly which machines are current, which are pending, and which need attention. Exportable reports support POPIA compliance and client audits.
The Security Argument
Unpatched software is the number one attack vector for ransomware in South Africa. The equation is simple: every unpatched vulnerability is an open door. Automated patching closes those doors systematically.
Consider the timeline of a typical exploit:
1. Vendor discovers vulnerability and releases a patch 2. Security researchers publish details of the vulnerability 3. Attackers build exploit code targeting unpatched systems 4. Organisations that have not patched become targets
The gap between steps 2 and 3 is shrinking. In some cases, exploit code appears within hours of disclosure. Manual patching cannot keep up with that pace. Automation can.
The Business Argument
Beyond security, automated patching delivers measurable operational benefits:
- Reduced IT overhead. Your team stops spending hours each month on repetitive update tasks. - Fewer disruptions. Patches deploy during maintenance windows, not in the middle of the workday. - Compliance readiness. POPIA and industry frameworks require evidence of timely patching. Automated reports provide that evidence on demand. - Consistent environments. Every device runs the same software versions. Fewer compatibility issues. Fewer support tickets.
Close the Door
Every week that passes with unpatched software is a week your organisation is exposed. Automated patch management removes the guesswork, the delays, and the human error.
Unpatched software is an open door. OAS closes it automatically — every week, every device.
