In recent years, enterprise network architectures have changed rapidly: WAN and SD-WAN are often outsourced, LAN and WLAN are delivered as managed services, and firewalls run in the operator’s or MSP’s data center. The service works – but the customer’s visibility into what actually happens in the network is very limited. If that’s the case, it can and should be fixed with a small adjustment to the service agreement. CIO: take back control of your network – be prepared.
The old assumption that the customer doesn’t need to worry about this area when buying a managed service is quickly collapsing. The strongest evidence is the rapid shift toward newer solutions whose core argument is precisely better **network visibility and ownership**, and therefore faster reaction capability.
Mapping the Current State Comes First
Any plan for migration or development must start by mapping the current network environment. In too many cases, the customer organization has no access to its own network elements – no SNMP visibility, no read-only CLI rights, and no documentation that matches reality. When that happens, the network functions as a black box, and its development ends the day it is installed.
The Real Problem: Documentation Is Inaccurate
Almost every network development or consulting project shows the same pattern: documentation is outdated, inaccurate, and filled with secondary details that don’t help at all with modernization or vendor transition. The information that actually matters is usually missing — routing, VLANs, ACLs, NATs, RADIUS, software versions, physical connections, and so on.
The risk is a slow and expensive migration project where problems are fixed “on the fly” — and every mistake costs time, money, and credibility points on the CIO’s scorecard.
Prepare for Change Even If No Urgent Change Is Planned
The Solution Is Simple: The Right to Read Your Own Network. The service contract must explicitly state that the customer has read-only access to all managed network elements. This means, for example:
- SNMPv3 (authPriv) access to all routers, switches, firewalls, and WLAN controllers
- SSH read-only (show-only) CLI connections to devices
- API access to SD-WAN and WLAN systems
- Syslog and telemetry streams also sent to the customer’s own monitoring systems
- The right to use internal documentation and monitoring tools
These rights do not allow configuration changes (no risk) but provide full **network visibility** into the infrastructure when needed. This is “Take Back Control of Your Network” enabler.
Strategic Impact from the CIO’s Perspective
When **network visibility and ownership** are guaranteed in the contract, the network lifecycle becomes manageable. A complete mapping and documentation can be generated dynamically in a few days, enabling development or migration to proceed 10× faster, with lower risk and far lower cost.
- Modernization speed: Migration or renewal starts from real configurations, not assumptions → project kickoff time typically drops by 80%.
- Vendor independence: The network no longer locks the organization to specific service partners or individual know-how → competition and contract renewals become easier.
- Risk management: Decision-makers rely on facts, not interpretations → audits and security assessments are based on the real state of the network.
Result: 100% accurate baseline data and better collaboration with service providers.
Transparency doesn’t threaten the provider — it strengthens trust.
Act Now
If your network is outsourced, check your agreement. Do you have the right to read configurations, SNMP states, and firewall rules from your own HQ or data center? If not, add it to the next contract negotiation.
Let’s start from a simple principle: the customer owns the company’s network configuration, regardless of who owns the hardware. There is nothing in a configuration file that constitutes provider-specific know-how or trade secrets — at most, it might reveal critical omissions or errors.
This simple clause can cut modernization and vendor-transition costs by up to 80% — and most importantly, give you back what should never have been lost: visibility and ownership of your own network.
CIO — take back control of your network
I’ve participated in hundreds of network modernization and migration projects where network visibility and ownership determined the entire project’s success. I can help you evaluate:
- What access and information your organization actually needs
- How those rights should be written into the contract
- What tools are best suited for documentation and monitoring
A little prevention at this stage can save months of work and significant costs during the next change. After that, a consultant can generate precise, up-to-date network documentation in just a few days to serve as a reliable baseline for your next modernization or vendor transition.
