The Problem

Most network documentation is outdated

Created manually, never updated

Visio drawings are created once and never kept up to date after the first infrastructure change. Within a few months, the diagram no longer matches the actual network.

No complete picture

Servers, clients and network devices are documented in different places. Anyone trying to understand the topology has to piece together multiple sources and hope they are all current.

No overview when things break

When a switch fails, the information about which systems depended on it is missing. Troubleshooting starts from scratch, and downtime grows.

The Path

How complete network documentation is built

Complete network documentation starts with agentless discovery using standard protocols such as SNMP, WMI and SSH. The collected data on switches, routers and other network components flows into a central CMDB. From that data, Docusnap365 generates network diagrams, topology maps and routing plans automatically and updates them with every scan cycle.

Step 1

Discover

The Docusnap Enterprise Gateway scans your network agentlessly via SNMP, WMI and SSH. Switches, routers, firewalls and access points are captured with their configuration and connections.

Step 2

Centralize

All scan results flow automatically into the cloud CMDB. On-premises devices and cloud services end up in the same data store, across locations and fully versioned.

Step 3

Document

Docusnap365 generates network diagrams, topology maps and routing plans directly from the scan data. The diagrams update with every scan cycle. Export as Visio and PDF.

What Docusnap365 captures in your network

Network inventory is part of the central IT documentation, where network components are documented alongside servers, clients, virtualization and cloud services.

Network devices

Switches, routers and firewalls via SNMPv1/v2 and SNMPv3. Cisco Meraki devices via the Meraki API.

IP infrastructure

DHCP scopes, DNS zones, IP hosts and subnets. The logical network structure is fully mapped.

Connections and dependencies

Which device on which port, which server reachable through which switch. Relationships are created automatically during the inventory.

Generated diagrams

Topology maps, network diagrams and routing plans. Updated with every scan. Export as Visio and PDF.

Frequently asked questions about network documentation

What should complete network documentation include?

Complete network documentation covers all active components (switches, routers, firewalls, access points), the logical network structure (IP addresses, subnets, VLANs, DNS zones, DHCP scopes) and the connections between devices. This includes topology maps, network diagrams and routing plans. Docusnap365 captures this data automatically via SNMP and generates the diagrams from the scan results.

How does network documentation stay up to date?

Through scheduled scans. The Docusnap Enterprise Gateway runs regular inventories whose results are automatically transferred to the CMDB. With every scan cycle, network diagrams and topology maps update themselves. The journal shows what changed between two scan points. More: Keep IT documentation up to date

Do I need software agents on the network devices?

No. Docusnap365 works entirely without agents. Discovery uses standard protocols (SNMP, WMI, SSH). No software is installed on the network devices. The only prerequisite: the locally installed Docusnap Enterprise Gateway must be able to reach the devices over the network.

Does network documentation help with audits and certifications?

Yes. Frameworks such as ISO 27001, NIS 2 and BSI IT-Grundschutz require up-to-date documentation of the IT infrastructure. Docusnap365 provides this documentation based on actual scan data, not manual entries. Diagrams and inventory data are ready as evidence when the auditor requests them.
