Secure Access Secure Edge (SASE) and Zero Trust (ZT) represent a critical evolutionary step for ensuring holistic SD-WAN security in the post-Covid multi-cloud environment – ‘Secure SD-WAN.’ Learn why a comprehensive test and validation strategy is essential to ensure Secure SD-WAN’s promise of being the ‘on-ramp of choice to the cloud’ for a growing number of enterprises.

SASE and ZT are critical for holistic SD-WAN security in the post-Covid multi-cloud environment. A next-gen test strategy is required to achieve Secure SD-WAN.

SASE and ZT: SD-WAN’s New Normal for Security

New Spirent eBook sets out how to create a test plan for selecting and integrating a GNSS receiver.

Secure Access Secure Edge (SASE) represents an evolutionary step for SD-WAN vendors to enhance SD-WAN security in the multi-cloud environment. Learn why a comprehensive test and validation strategy is essential to manage SD-WAN security effectively.

Tame the risks of SD-WAN: SD-WAN’s security evolution must incorporate SASE and the comprehensive test and validation strategies that support it.

Evolving SD-WAN Security and SASE Architecture

SD-WAN’s security evolution must incorporate SASE and the next-gen test and assurance strategies that support it.

Taming the Risks of SD-WAN: Evolving SD-WAN Security and SASE Architecture

SD‑WAN is quickly evolving from upholding physical on-premises connectivity to becoming cloud-centric. This was accelerated by the Covid pandemic, where remote work became widespread, and redefined networking in the process. This disruption resulted in more sophisticated threats, which in turn has elevated the urgency and importance of holistic security. 

Spirent has developed a three-step testing strategy guideline to help manage Secure SD-WAN complexity, ensure comprehensive security, and help realize the full potential of the technology while controlling costs.

Paving the Way to Secure SD‑WAN

Creating a realistic test environment is essential for understanding the receiver’s likely behaviour in real-world adversarial conditions.

Spoofing and other vulnerabilities testing is critical for GNSS-enabled technology. Find out how improved realism through Spirent's Standpoint can enhance your PNT testing.

The certification differentiates market leaders, validates MSP and vendor claims and enables multi-vendor SD-WAN.

Intermodulation Distortion (IMD) is an issue that 5G operators, device manufacturers, and consumers must not ignore when it comes to accurate positioning.

IMD interference is generated by LTE and 5G working simultaneously and can impact location-based applications. Spirent is working with operators to identify and manage this issue.

Today, 80% of the 240 million 911 calls made annually are from mobile phones. Unfortunately, vertical positioning (Z-axis) data to help locate callers in multi-level structures has tended to be missing or inaccurate. Learn how testing and measurement suites are used to validate data sent to 911 including Z-axis accuracy.

When a 911 call comes in from a mobile device, providing vertical location data, or z-axis, is more difficult than first realized and the FCC is putting onus on carriers to provide accurate data.

The FCC issued deadlines for carrier compliance to improve Z-axis location accuracy for all wireless 911 calls. This now includes the top 50 cellular market areas (CMAs) in the U.S, where the nationwide carriers must comply or face significant fines. Learn the proven Z-axis vendor-neutral test methodology to comply with the FCC’s requirements before the deadline.
