Netskope Details How SASE Addresses Legacy Network Security Costs

The vendor blog argues that legacy, fragmented network security architectures are driving high integration and latency costs while teams face staffing and budget constraints. It positions a SASE model—converging networking and security—as a way to consolidate tooling and reduce operational friction for enterprise leaders.

Research Overview

The post frames enterprise security and infrastructure needs in the context of remote work, cloud-hosted data, and predominantly SaaS applications. It also describes ongoing challenges for I&O and cybersecurity teams as they try to move away from legacy network security infrastructure.

It cites survey results from I&O leaders regarding infrastructure centrality to business goals, rising expectations, confidence in resourcing, and views on whether current infrastructure can meet new requirements.

Key Findings

The blog links legacy infrastructure to technical debt, including the integration overhead of managing many disconnected security vendors. It also describes a “latency tax” when traffic must be backhauled to a physical office to access cloud applications.

It further states that these issues increase as organizations adopt AI into their workforce at scale, because the risk of issues such as sensitive information leakage grows with adoption.

Operational Impact

The post reports that 80% of I&O leaders say IT infrastructure has become central to delivering on core business goals and 83% say expectations intensified over the past 12 months. It adds that 18% are completely confident they have the people and budget to meet future requirements.

It also states that 38% of I&O leaders believe their current infrastructure is fully equipped for these demands, leaving many teams reactive and constrained by legacy systems, according to the blog.

Technical Breakdown

The blog describes SASE as an architecture that converges networking and security using security service edge (SSE) capabilities within a single software stack. It says the approach consolidates vendors and eliminates data center, hardware, and physical equipment.

It attributes cost and performance outcomes to a Forrester Total Economic Impact study and links these outcomes to user proximity at the edge, including reduced latency for applications and improved availability for network services.

Research Findings Cited for SASE Outcomes

The post states that the vendor-identified TCO reduction from consolidating security and networking infrastructure typically ranges from 20% to 40%. It adds that a Forrester study found consolidated network security infrastructure generated 37% of total business value, with $5.4 million in cost reductions over three years.

It also says the Forrester study attributed $2.4 million in cost reductions to improved network availability and performance, citing a 10% increase in uptime for core network services and an 80% reduction in help desk tickets.

Leadership Perspective

The blog positions SASE as a way to move organizations toward more resilient risk management and to support a unified data protection policy that follows users as they work. It frames this as aligning security and I&O leaders around shared operational policies.

It also presents the Netskope Business Value Services (BVS) offering as support for building a business case for SASE migration, citing the Valueskope platform and a set of activities used to quantify economic impact.

Business Value Services Offerings

The post states that BVS experts help craft a tailored business case aligned to an organization’s data and strategic goals. It says the work includes comprehensive TCO analysis focused on tool sprawl, value realization roadmaps using a three- to five-year analysis period, and risk quantification using industry-standard frameworks.

It adds that BVS includes peer benchmarking to compare security spend and efficiency within the organization’s industry.

Overall, the blog connects legacy security and networking sprawl to technical debt, integration overhead, and backhaul latency, then points to a SASE approach for consolidation and user-edge proximity. It also describes Netskope Business Value Services as a framework for quantifying costs, returns, and risk reductions. This “Blog Signals brief” is a fact-based summary of the vendor blog.
