rConfigCisco SNMP Vulnerability CVE-2025-20352: What You Need to Know — and How to Remediate with rConfig
On September 24, 2025, Cisco disclosed a serious vulnerability in the Simple Network Management Protocol (SNMP) subsystem of Cisco IOS and IOS XE software, tracked as CVE-2025-20352.
Vendor Agnostic Network ManagementMulti Vendor Network Configuration Management: Managing Cisco, Juniper, and Fortinet Together
The decision to build a multi-vendor network goes beyond simple business logistics. It's often driven by specific technical requirements. For instance, an organization might rely on Cisco for its robust core campus switching, leverage Juniper for its high-performance edge routing, and deploy Fortinet for its next-generation firewall security. Each choice is optimal for its specific function, creating a powerful, specialized infrastructure. This approach delivers a significant strategic advantage, but it comes with a steep management cost.
Network Configuration ManagementHow to Restore Network Device Configurations Safely: Rollback Strategies for Routers and Switches
The act of backing up a network device is passive. It’s a read-only operation that captures the state of a device at a single moment in time. Restoring, on the other hand, is an active intervention. You are writing a new set of instructions to a live piece of hardware, and the context of the network has likely changed since that backup was created. This context is everything.
Vendor Agnostic Network ManagementVendor Agnostic Network Management: Why Enterprises Are Moving Away from Single Vendor Tooling
The term "vendor-agnostic" is often used interchangeably with "multi-vendor," but they represent two very different concepts. Understanding the distinction is fundamental. A multi-vendor network is the common state of most enterprises, it is the problem of hardware diversity. A vendor-agnostic strategy, on the other hand, is the deliberate solution to that problem.
rConfig V8FortiSwitch Admin Password Vulnerability (CVE-2024-48887): How rConfig Automatically Detects & Secures You At Scale
A new critical vulnerability (CVE-2025-20188) in Cisco IOS XE Wireless Controller Software allows unauthenticated attackers to execute commands with root privileges. With a perfect CVSS score of 10.0, this flaw demands immediate attention from network teams. This post details the vulnerability and shows how rConfig automates detection and remediation across your Catalyst 9800 devices in minutes, not days.
Network AutomationNetwork Automation Isn’t About Speed—It’s About Predictability
In high-stakes environments, from manufacturing floors to financial markets, success is measured not by raw speed but by the consistency of outcomes. A pharmaceutical company values a perfectly replicated formula over a rushed batch. A pilot prioritizes a stable flight path over record-breaking velocity. The same principle applies to modern IT, where the true value of network automation lies in its ability to deliver predictable, auditable results every time.
Network Change ManagementNetwork Configuration Change Reports: How to Prove Who Changed What (and When)
A comprehensive configuration history is more than just a log file; it is the single source of truth for your network's state over time. It documents the evolution of every device, from its initial deployment to its most recent modification. This historical record is a non-negotiable asset, providing immense operational and business value that extends far beyond simple troubleshooting.
