• deeploi automates the entire patch management process: At deeploi, we take care of all relevant patches on your devices and provide a central overview of patch status. Our support responds in an average of 12 minutes.

Why patch management is critical for businesses

Patch management is not a technical nice to have. It is business critical for every company. Unpatched systems are the biggest entry point for cyberattacks. Most successful attacks exploit known vulnerabilities for which patches have long been available. Without structured patch management, you risk data loss, system outages, and serious financial and legal consequences.

The three most important reasons for professional patch management:

• Cybersecurity: Security patches close critical vulnerabilities before attackers can exploit them for ransomware, malware, or data theft. Every day without a patch increases your risk exponentially.
• Compliance: Missing patches can lead to compliance violations, resulting in significant fines and reputational damage.
• Productivity: Outdated software causes system instability, crashes, and compatibility issues. Regular patching ensures stable systems and minimizes unplanned downtime that prevents your team from working.

The challenge: Manual vulnerability management is time consuming, requires IT expertise, and does not scale as companies grow. Modern patch management solutions address these pain points through automation, centralized management, and proactive monitoring, without requiring you to be an IT expert.

The patch management process – how it works properly

The 5 phases of patch management

A structured patch management process ensures that all systems remain secure and stable. Without a clear methodology, critical patches are overlooked or cause unexpected issues. When done manually, this process is extremely time consuming. With automation, however, it can be drastically simplified.

1. Identification: Detecting available patches for operating systems, applications, and third party software. Modern tools automatically scan all devices and compare them with patch databases. Example: A critical Windows security patch is released – your system detects it immediately and flags the affected devices.
2. Assessment: Prioritizing patches based on criticality and risk. Security patches for known vulnerabilities have the highest priority, while feature updates can wait. Example: A patch for an actively exploited vulnerability is classified as critical and scheduled immediately.
3. Testing: Compatibility checks in pilot groups before patches are rolled out company wide. This allows you to identify potential conflicts early. Example: The patch is first installed on three test devices and monitored for 24 hours.
4. Deployment: Staged distribution of patches to all endpoints – first the test group, then a gradual rollout. Automated systems handle installation outside of working hours. Example: Patches are installed overnight so employees can start the day with up to date systems.
5. Documentation: Complete documentation of all patching activities for compliance purposes. Which device received which patch, and when?

Automated vs. manual patch management – the difference

The difference between manual and automated patch management is significant – especially for companies without a dedicated IT department. While manual processes are time intensive, error prone, and not scalable, automation enables consistent, fast, and reliable patch distribution across all devices.

Especially for companies without an IT department, automation is not optional, but essential. Modern platforms like deeploi provide automated patch management – without requiring IT expertise or manual processes.

Selection criteria for patch management tools

Choosing the right patch management solution determines whether your IT security becomes a competitive advantage or a burden. Especially for accidental IT owners, meaning people who manage IT alongside their actual role, certain criteria are critical.

• Cross platform support: The solution should cover all operating systems used in your company – Windows, macOS, and mobile devices such as iOS. This is the only way to avoid isolated solutions and maintain full visibility of all assets within one central platform.
• Automation and orchestration: Autonomous patch distribution without manual intervention is essential. The solution should automatically identify, prioritize, and install patches. Intelligent scheduling ensures updates are installed outside working hours so productivity is not affected.
• Usability for non IT experts: An intuitive user interface with clear dashboards gives you a complete overview of patch status across all systems, without requiring technical expertise. Color coded status indicators, easy to understand notifications, and simple workflows are essential.
• Support and proactive expertise: Fast response times and proactive guidance make the difference. You need a partner who does more than provide software, someone who actively supports you and anticipates issues before they arise.

Best practices: how to implement effective patch management

Structured patch management is only as good as the processes behind it. These seven best practices help you systematically close security gaps, meet compliance requirements, and make optimal use of your IT resources.

1. Define clear patch policies: Specify which patches are installed and when. Categorize them by criticality, such as critical security patches, important updates, and optional features, and define maintenance windows for different systems. This ensures business critical patches are prioritized while less urgent updates are rolled out in a planned manner.
2. Create full transparency: Complete asset inventory is the foundation of effective patch management. You must always know which devices, software, and operating systems are in use in your company. A real time overview of patch status across all assets prevents systems from being overlooked and turning into security risks.
3. Prioritize by risk and impact: Not all patches are equally important. Critical security patches that close actively exploited vulnerabilities have top priority. Assess patches based on threat level, affected systems, and potential impact on your business.
4. Test before production rollout: Install new patches on pilot groups first to identify compatibility issues early. Define a clear rollback strategy in case a patch causes unexpected problems. This minimizes the risk of system outages in production environments.
5. Automate standardized processes: Routine patches for operating systems and commonly used applications should be distributed automatically. Retain manual control only for critical systems or complex applications. Automation significantly reduces human error and accelerates patch distribution.
6. Document consistently and completely: Document which device received which patch and when, who approved the patching process, and whether it was successful.
7. Review and optimize regularly: Create monthly reports on patch status, compliance rates, and any issues encountered. Analyze weaknesses in your process and continuously improve. Regular reviews ensure your patch management keeps pace with the growing demands of your company.

The process is fairly complex. The good news is that with the right patch management solution, these best practices are implemented automatically. Modern platforms support all seven points natively, from automatic asset inventory and intelligent prioritization to complete documentation. This allows you to benefit from professional vulnerability management without having to be an IT expert yourself.
