SonicWall NSSP 15700 Secure Upgrade Plus ESSN 3YR | Firewall Service

Keep your SonicWall NSSP 15700 supported with a service plan designed for continuity, not guesswork. Secure Upgrade Plus Essential Edition provides a 3-year coverage window that helps organizations plan around lifecycle risk, reduce exposure to unplanned downtime, and maintain confidence in a firewall that protects critical traffic. For infrastructure teams, the real value of extended service is operational predictability. A longer support term helps align maintenance planning, budget cycles, and replacement strategy while reducing the pressure of unexpected hardware issues. That matters when the firewall is part of a broader security architecture supporting users, applications, and remote access. This service is a practical choice for organizations that want to preserve the investment in a high-value SonicWall deployment and avoid the cost and disruption of reactive support decisions. It adds a defined support layer around a core security asset so teams can stay focused on policy, performance, and availability.
