Cisco DefensePro VA 500 Security Update Sub SMS-1K | Security Update — RDDSS-500M-SMS-1K

Maintain current security update coverage for DefensePro VA 500 with this Cisco SMS-1K subscription. For teams running virtual appliance-based protection, staying current is not optional: it is what keeps defenses aligned with evolving threats and operational requirements. This subscription is built to support that ongoing maintenance model. Rather than treating updates as an afterthought, the SUS structure gives procurement and operations a defined renewal path for continued access. That helps reduce administrative friction while keeping the appliance’s security posture current across its service life. It is especially useful in environments where virtual security infrastructure must remain stable, documented, and easy to renew. DefensePro VA 500 deployments often sit in front of critical services, so update continuity matters. This subscription supports that continuity with a clearly scoped licensing package, making it easier to plan budgets, track entitlements, and keep protection aligned to the appliance in production.
