A solid network automation strategy can slash firewall rule deployment from weeks to mere minutes, significantly improving both security posture and operational efficiency. This isn’t just about speed; it’s about embedding compliance and consistency directly into your network operations, ensuring every change meets regulatory requirements without manual oversight.
I’ve watched network operations evolve from punch cards (okay, maybe not that far back, but close!) to the cloud. What hasn’t changed is the pain of manual firewall rule changes. Think about it: an internal customer submits a request, a network engineer reviews IPs and FQDNs, maybe it goes to a Change Advisory Board (CAB), then another team implements it. If there’s a problem, it cycles back. We’ve seen this with clients where a simple port opening could drag on for weeks, creating massive bottlenecks for mission-critical applications.
The core problem isn’t the firewall itself, it’s the data. Orsted, a major energy company, found their network data scattered across everything from systems without APIs to Excel spreadsheets. How can you automate anything when your source of truth is a patchwork quilt? They realized that before any automation could happen, they needed a centralized, validated data platform. This isn’t just a best practice; it’s a prerequisite for any meaningful network transformation.
Many businesses think automation is just about “time to market” – how fast you can deploy. But the real game-changer is compliance. When a machine executes a process designed with compliance in mind, you get 100% adherence, every single time. No human error, no forgotten steps, just consistent, auditable execution. This is especially critical for regulated industries like energy, finance, or healthcare, where audits are a constant threat. For a deeper dive into compliance frameworks, the NIST Special Publication 800-53 provides comprehensive guidance on security and privacy controls.
building a network automation strategy that works
Here’s what nobody is talking about enough: the biggest hurdle isn’t the tech, it’s the culture. We’ve been doing this for over 30 years at CTS, from structured cabling in the 90s to VoIP rollouts in the 2000s, and now AI chatbots. Every single time, the technical part is solvable. Getting different teams – network engineers, security, developers, and the business units – to agree on a standardized process? That’s the real challenge. Orsted, for example, had to run a design sprint just to get everyone on the same page for their firewall process. You can have the best tools, but if your people aren’t aligned, you’re dead in the water.
Orsted chose Nautobot, an open-source network automation platform, to centralize their data and build custom validators. This allowed them to model specific network concepts like “zones” and connect IP addresses directly to the policies governing them. This isn’t just about scripting individual tasks; it’s about treating network automation as a product. You need version control, change logs, and dedicated support for the people using it. So many companies throw a few Ansible playbooks together and call it “automation.” That’s a start, but it’s not a sustainable strategy.
One of the most impactful changes Orsted made was categorizing firewall requests. They identified lower-risk traffic flows that could bypass the full CAB approval process, instead relying on peer review. This simple change meant 60-70% of requests could be deployed in approximately 10 minutes, rather than days or weeks. For the remaining high-risk requests, CAB approval is still mandatory – no exceptions. This isn’t just faster; it also provides invaluable traceability, linking every firewall rule back to its change request, customer, and team.
So, what does this mean for your business? Don’t chase speed first. Chase data integrity and compliance. Here’s how you can start this week:
- Audit Your Data Sources: Where is your network information? Is it in spreadsheets, disparate systems, or a proper Configuration Management Database (CMDB)? Centralize it.
- Define Your Compliance Needs: What regulations (HIPAA, PCI DSS, SOX) impact your network changes? Work with security to embed these checks into automated workflows.
- Start Small, Think Big: Pick one tedious, high-frequency, low-risk network task – like a specific type of firewall rule change – and automate it. Treat this pilot project like a product, with clear documentation and user support.
- Get Cross-Functional Buy-In: Automation isn’t just for IT. Involve security, operations, and even internal customers in the design process. Cultural alignment is as important as technical prowess.

Frequently asked questions
What is the primary benefit of network automation beyond speed?
Beyond speed, network automation's primary benefit is embedding compliance and consistency, ensuring every change adheres to security policies and regulatory requirements without manual errors.
How long does it typically take to implement a basic network automation system?
Implementing a basic network automation system can vary, but focusing on a single, well-defined process might take a few weeks to a couple of months for initial deployment, depending on data readiness and team alignment.
What are common tools used for network automation?
Common tools for network automation include open-source platforms like Nautobot and Ansible, and commercial solutions like Cisco DNA Center or Juniper Apstra, often integrated with IT service management (ITSM) platforms like ServiceNow.
Is network automation only for large enterprises?
No, while large enterprises often have complex needs, small to medium-sized businesses (SMBs) can also benefit significantly from automating repetitive tasks, improving efficiency, and reducing human error in their IT operations.
