Cisco RDSU20-2-SMS-1K Security Update Subscription | Licensing — RDSU20-2-SMS-1K

Keep DP20-2 SMS-1K environments aligned with current security maintenance through a Cisco Security Update Subscription. Built for organizations that need predictable software upkeep, this subscription provides access to security updates tied to the covered product, helping reduce risk from known vulnerabilities and maintain operational continuity. For infrastructure teams, the value is control. Instead of managing software drift across deployed systems, you maintain a defined update path for the licensed product. That matters when uptime, compliance, and change discipline all sit in the same approval chain. It also helps procurement standardize recurring software coverage rather than treating patch access as an ad hoc expense. This subscription is suited to environments where the covered Cisco software remains in service and security maintenance is part of the support model. It is a practical way to preserve the value of the underlying deployment while keeping the software aligned with vendor-issued updates.
