If you’re like most IT and security pros, your to-do list looks like a game of whack-a-mole—troubleshooting slow internet here, wrestling with clunky security policies there, and spending way too much time managing tools that don’t play nicely together. Oh, and let’s not forget juggling ever-growing licensing costs, all while crossing your fingers that nothing major breaks. The truth is, keeping the IT environment secure and providing enhanced user experience feels harder than ever these days. And the legacy security solutions from years ago aren’t exactly pulling their weight. Half the time, they feel like band-aids holding together an ancient ship in an ocean of modern cyber threats. It’s not surprising, then, that the cracks are showing—whether it’s higher costs, slower workflows, or risk exposure. The good news? There are better ways to tackle these challenges, and some fresh data proves it. The Total Economic Impact™ Of Zscaler Internet Access, a Forrester Consulting study commissioned by Zscaler in April 2025, highlights how organizations can overcome challenges in ensuring secure, efficient, and reliable internet access in today’s rapidly evolving digital landscape. Let’s Talk About the Pain PointsBefore we cover the key highlights from the commissioned study and findings, let’s acknowledge what today’s IT and security teams are dealing with:High operational costs: Maintaining and managing a complex array of legacy solutions and infrastructure to secure internet access is costly, both in terms of financial resources and human effort.Security gaps: Every IT pro dreams of zero downtime and no breaches—but the fragmented nature of legacy solutions leads to gaps in security coverage, increasing the risk of breaches. Lack of comprehensive visibility and control over internet-bound transactions can leave you vulnerable to threats.Latency issues: Few things kill productivity as quickly as latency and connectivity issues. Whether it’s challenges accessing public Wi-Fi or company portals, nothing puts users (and their IT teams) in a bad mood faster.Scalability challenges: It can be challenging to handle increasing traffic and user demands, particularly during the shift to remote work or expansion to new offices with legacy infrastructures.Complex security policy management: Integrating multiple legacy tools and solutions is complex and often results in inconsistent security policies and management. Interviewees noted this disjointed experience made it difficult to ensure seamless integration and consistent security across hybrid environments.Sound painfully familiar? You’re not alone—this is a reality that plenty of IT and security professionals face every day.Cost Savings And Business Benefits Enabled By Zscaler Internet Access (ZIA)Zscaler commissioned Forrester Consulting to conduct a Total Economic Impact™ (TEI) study and examine the potential return on investment (ROI) enterprises may realize by deploying Zscaler Internet Access (ZIA). The TEI study examined what happened when organizations modernized their approach to secure internet access. It wasn’t just about upgrading to a new solution—it was about making a fundamental shift to zero trust security architecture that promoted efficiency, security, and, dare we say it, sanity. The results? Let’s just say they’re “bookmark-worthy.”To better understand the benefits, costs, and risks associated with this investment, Forrester interviewed five decision-makers with experience using Zscaler Internet Access (ZIA). For this study, experiences of the interviewees were aggregated, and the results were combined into a single composite organization, which is a global organization with 15,000 employees and revenue of $10 billion per year.1. Better ROIThe composite organization experienced a significant 267% ROI by deploying ZIA. If your current setup is eating resources, it might be time to rethink what your budget could be doing elsewhere. Who doesn’t love a stat like this? “ZIA has improved network performance and made application access faster and more reliable. Its cloud-based approach reduces delays and ensures secure, seamless connectivity. Users benefit from better speed, scalability, and security without the need for complex setups.”- Network security lead, technology2. Technology Cost SavingsYou know that licensing fee you dread renewing every year? Or the hardware maintenance cost that’s slowly draining the life out of your budget? By reducing dependence on legacy systems, the composite organization saved a measurable $1.5 million over three years. Yes, that’s seven figures of “we could use that elsewhere” money. “If I tried to deploy [our legacy on-premises web security solution] at every remote office that I have, it would have been financially untenable. It would have been around $50K a box. When you start multiplying that by hundreds of sites, it is just untenable.”- Director of cybersecurity, insurance3. Operational EfficiencyYou know that great feeling when your inbox doesn’t explode before 9 a.m.? Imagine that every day. By transitioning to ZIA, IT, network, and security professionals save substantial hours previously spent on configuring and managing security policies, SSL/TLS inspection, and troubleshooting issues. The composite organization saw a 75% improvement in IT and security operational efficiency.“Managing SSL connectivity required two full-time employees [in our legacy environment] but with Zscaler, this task was reduced to a fraction of one employee’s time.”- Director of cybersecurity, insurance4. Strengthened SecurityImplementing ZIA strengthens security and improves overall security architecture for the composite organization. By transitioning to Zscaler’s zero trust architecture, the composite organization enhances its security posture, improves threat detection and response capabilities, and reduces the likelihood of cybersecurity breaches.“ZIA has improved SSL/TLS inspection by providing deep visibility into encrypted traffic without slowing down performance. It helps detect threats hidden in secure connections, ensuring better protection while maintaining fast and seamless access for users.”- Network security lead, technology5. %26lt;6 Months Payback PeriodHere’s one to share with the team: The TEI study highlights a significant payback period of under six months with ZIAWant the Full Story?Here’s the deal: these stats are the tip of the iceberg. The TEI study goes even deeper into the numbers, the methodology behind them, and the tangible impact modernizing secure internet access had on IT and security teams.
