Downtime is expensive. More than half (54%) of the respondents to the 2023 Uptime Institute data center survey say their most recent significant, serious, or severe outage cost more than $100,000, with 16% saying that their most recent outage cost more than $1 million.
The phrase from the movie, Apollo 13, “Failure is not an option,” is one of the most recognizable movie taglines of all time.
In network operations, it’s the same mindset. Money and reputation are on the line. Failure is not an option.
So why are we still so vulnerable given all the redundancy networks have built into them? Why do we continue to rely so heavily on manual processes and reactive troubleshooting? Network engineers spend countless hours putting in place the foundation for service delivery, yet there’s little or no regular enforcement. Only, when a problem is reported, are the wheels of troubleshooting put into (slow) motion.
In 2021, a critical application at stc suffered a major service disruption. It took nearly a month of troubleshooting across network operations, servers, applications, and security teams to identify the cause and restore service. This costly outage highlighted the need for better visibility and a more strategic approach to incident management. As a result, stc’s Group CTO pushed for an organization-wide solution that provides end-to-end visibility and automates incident management across infrastructure and applications.
Network automation has now rapidly advanced to be able to continuously assess a network’s operating conditions without any development cycles. NetBrain has created a set of the most common assessments enterprise network operations require to ensure outage-resistant operations. However, the no-code automation platform ensures network operations aren’t limited to a finite set of assessments. Without adding resources, you can easily build on these templates and create your system of continuous assessments for your unique network needs. And, you can visualize and share network-wide assessment results via widget-based summary dashboards.
Let’s explore the top 10 outage-preventing network assessments and see how NetBrain can craft these in minutes.
Top 10 Outage-Prevention Network Assessments
1. Change Assessment
At the start of every week, there are reports of network outages triggering the question: What changed over the weekend, and where did these changes occur?

With a Change Assessment, you continuously evaluate and summarize:
- Device results by device group
- ACL configuration changes
- Routing configuration changes
- Switching configuration changes
- Failover configuration changes
2. Anti-Drift Assessment
Human error, often stemming from manual network changes, is a leading cause of network outages. To address this, use a network Anti-drift Assessment to identify deviations from established configuration rules and best practices. By automating the enforcement of these rules, you can significantly reduce the prevalence of human error and safeguard network stability.
The Anti-drift Assessment encompasses three rule categories:
- Design and Best Practice Rules: These rules outline industry-wide best practices for network configurations, ensuring that the network aligns with recognized standards and guidelines.
- Golden Config Rules: These rules represent the organization’s specific configuration standards, mandating adherence to internal policies and procedures.
- User-Submitted Design Rules: These rules capture network architects’ and engineers’ expertise, encapsulating design principles and guidelines tailored to the organization’s unique network topology and requirements.
By automating the enforcement of these rules, you can effectively prevent configuration drift and minimize the risk of human error. This proactive approach not only enhances network stability but also improves overall network performance and security.
3. Network Health Assessment
Sophisticated network redundancy provides reliable and high-performance connectivity. However, these features, if not properly monitored and maintained, can become sources of potential issues. Continuous network health assessment plays a critical role in identifying and addressing potential problems before they escalate into major outages.
Network health assessment encompasses a comprehensive evaluation of routing, switching, failover, VPN, wireless and error logs.
By continuously assessing these critical network components, you can proactively identify and resolve potential problems, ensuring optimal network performance, availability, and security.
4. Critical Application Assessment
By continuously monitoring and evaluating the health of mission-critical applications, you can identify and address potential issues before they impact users or disrupt business processes. This proactive approach helps prevent costly outages, optimize application performance, and enhance overall system reliability.
Application health assessment encompasses a comprehensive evaluation of various application metrics and components, including CPU and memory capacity, QoS drops, critical interface utilization and tasks such as log analysis and event monitoring to proactively identify and address potential application issues.
By continuously assessing these critical application metrics, you can gain valuable insights into application health, enabling you to optimize performance, prevent outages, and maintain a positive user experience.
5. Security Assessment
Ensure your network isn’t vulnerable according to NIST Standard and CVE Bulletins. From security compliance to vendor recommendations, assess any vulnerabilities and fix them before problems occur. Regular network security assessments are essential to identify and address vulnerabilities that could compromise sensitive data, disrupt operations, or damage an organization’s reputation.
Network security assessments encompass a comprehensive evaluation of various security aspects, including:
- Compliance with NIST and NERC Standards
- Vulnerability Detection using the Common Vulnerabilities and Exposures (CVE) catalog
- Misconfigurations that could create security gaps, such as weak passwords, insecure protocols, and unauthorized access permissions
- Intrusion Detection/Prevention (IDS/IPS): Analyze IDS/IPS logs
- Network traffic analysis: Monitor network traffic to detect anomalies that could indicate suspicious activity or network attacks
By automating these security assessments, you can continuously monitor network posture, proactively identify, and address vulnerabilities, and maintain a robust defense against evolving cyber threats.
6. Lifecycle Assessment
A comprehensive lifecycle assessment can help you stay informed about the lifecycle status of your network hardware, ensuring timely upgrades and replacement decisions.
By leveraging automated API calls to hardware vendors, such as Cisco, get real-time information on:
- End-of-Life (EOL) Status
- Maintenance Status:
- Service Contract Status
- Warranty Information
Make informed decisions about hardware lifecycle management, optimizing their network for performance, security, and cost-effectiveness.
7. Hybrid-Cloud Network Assessment
By applying automation to hybrid-cloud network assessment, you can continuously monitor and assess your cloud networks across multiple cloud providers, including Microsoft Azure, Amazon AWS, and Google Cloud for insights into:

8. Triggered Automation
The Triggered Automation Assessment serves as a centralized hub for monitoring and responding to network incidents in real time. By harnessing the power of automation, streamline incident management processes, enabling rapid diagnosis, prioritization, and resolution.
Upon receiving an incoming incident notification via API, the triggered automation dashboard applies intelligent auto-diagnosis capabilities:
- Auto-closing Ticket: If the incident is identified as noise, the ticket is automatically closed, reducing the workload for network engineers, and eliminating unnecessary escalations.
- Auto-opening Ticket: In cases where a network issue is found, automatically open a ticket, ensuring that the incident is promptly addressed and documented.
- Auto-prioritizing Ticket: If a high-impact issue is found, automatically assign the ticket to a high priority, alerting network engineers to the urgency of the situation and enabling rapid intervention.
Automating these critical incident management tasks significantly reduces response times, minimizes downtime, and enhances overall network resilience.
9. Past Outages Assessment
Are known problems happening again? After a network outage, assess any similar problems across your network. For every problem that happened in your network before, could it happen again in another part of your network?
It could. Apply problem-based assessment across your network and monitor the results continuously. To effectively prevent future outages, organizations must conduct thorough post-outage assessments, analyzing the root causes of past incidents and identifying potential vulnerabilities that could lead to similar issues.
By analyzing past outages, organizations can:
- Identify recurring patterns and underlying factors that contribute to network outages, allowing for targeted mitigation strategies.
