New SOLIDserver™ 9.0 DDI: Enhancing Stability, Robustness, and UX

EfficientIP SOLIDserver™ 9.0 DDI is the first release in the new 9.x series. This release delivers a stable, reliable foundation for upcoming 9.x innovations while introducing key features to improve usability, security, and operational efficiency. New functionality brought by 9.0 includes the following:

Modern UI Engine Designed for Future Features and Evolution

Release 9.0 introduces a modern UI engine that  is more responsive, more performant, and more secure. The design has been modernized for consistency, with both Dark and Light themes to match user preferences and improve usability. Alignment with UX standards means navigation and tasks have become simpler and faster. Accessibility remains a priority, with WCAG 2.2 compliance maintained.

Enhanced DNS/DHCP Server Modes and DNS Capabilities

• New DNS / DHCP server modes (read-only, unmanaged, safe) provide safer, more controlled operations during upgrades, maintenance, or backup restoration, allowing IT teams to prevent unauthorized changes, simplify audits, minimize downtime, and ensure faster recovery.
• New Alias DNS records enable dynamic A records at the zone apex (like ANAME), working across all DNS engines, eliminating the need for web server redirects.

Telco-Grade Enhancements

• Guardian/Blast CGNAT enables precise DNS security policies for subscribers sharing the same IPv4 address by creating a unique client identifier, ensuring that policies and countermeasures apply only to the actual user, not the entire IP range, for greater accuracy and stronger security.
• DNS Guardian Prefetch Optimization boosts QPS, reduces latency, minimizes packet loss, and improves cache hit ratios for high-traffic environments.

In addition, while not part of SOLIDserver 9.0, a new enhancement to DNS Threat Pulse (DTP), the addition of a DoH category in the feed, was released in December 2025.

New DoH Category in DNS Threat Pulse (DTP)

This feature closes a growing blind spot where users and devices bypass corporate DNS security through encrypted DoH, often enabled by default in browsers. It restores visibility and control while minimizing exposure of internal network structures and data. Based on live-tested domains, it delivers high accuracy with very low false positives. Included in all DTP plans at no extra cost and available in CQF format for immediate use. All DTP customers benefit automatically from it, no activation required.

Key Benefits brought by SOLIDserver 9.0 include

• Stable, reliable foundation for upcoming innovations in the 9.x series
• More responsive, accessible, and secure UI
• Safer, more flexible server operations
• Enhanced DNS flexibility and security for enterprise and telco environments
• Optimized performance for high-traffic deployments
