Tackling Technical Debt and Redefining Application Access with the Enterprise Browser

‍

Organizations often find themselves held back by IT decisions, made many years ago, to incorporate the best technology available at the time. With the benefit of hindsight, such decisions can feel like an anchor to the organization, and managing such technical debt remains a critical issue for IT and cybersecurity executives. 

And understandably so; constrained by budget and time, organizations have responded to various emerging requirements by layering on new solutions, resulting in an unwieldy patchwork of tech stacks built over years. It has often been the nature of technology, and a universal challenge for organizations with technologies that may span decades.

In the context of application access, technical debt refers to the accumulation of inefficiencies, architectural limitations, outdated practices, and temporary fixes in application access and security efforts. Over time, tech debt in such areas can degrade system performance, increase vulnerability risks, and impede innovation — not to mention amass significant costs.

The annual cost of overall tech debt in the U.S.? $2.4 trillion, with a projected $1.5 trillion needed to manage these compounding technical expenses. That’s a staggering figure. Yet, even though tech debt has been a recognized issue since 1992, there are no easy solutions. Every organization must weigh competing priorities and risks, and it’s impractical to simply throw everything away and start with a clean-slate approach. This can mean tech debt will continue to grow.

How did we get here? And is there anything business leaders can do to reduce tech debt related to application access? (Read until the end: There’s hope on the horizon.)

What exactly is application access tech debt?

Here are some common examples:

• Virtual Desktop Infrastructure (VDI) and legacy remote access solutions. Many organizations implemented VDI and VPN solutions years ago to support remote work and application access. At the time, these were the best options around. However, these solutions are resource-intensive, costly, and often provide a subpar user experience due to latency and layers of complexity. VPNs also lack the granularity of modern zero trust solutions, expanding the attack surface for malicious attackers. This tech debt becomes particularly problematic as demand for seamless, fast, and secure remote access grows, especially in hybrid work environments, which are far more prevalent today than they were when organizations first implemented these solutions all those years ago. 
• Dependency on multiple security layers for basic browser security. Traditional consumer browsers require a complex ecosystem of tools — like data loss prevention (DLP), web gateways, remote browser isolation (RBI), and endpoint agents — to secure browsing and protect data. Over time, these layers compound in complexity and cost, contributing to tech debt in both security and application access by requiring ongoing management, troubleshooting, and upgrades.
• Legacy thick applications and outdated client-server models. Many businesses still rely on thick-client applications (installed locally on user devices) or older client-server models that aren’t optimized for cloud or web-based delivery. These require significant IT support and cannot easily integrate with modern, cloud-based solutions, which are increasingly table stakes for today’s global organizations. This reliance on legacy architectures adds friction to digital transformation and accumulates technical debt as applications require costly maintenance and support.
• Lack of integrated observability tools. With traditional application access models, observability often depends on network and endpoint monitoring solutions that lack application and workflow context. As organizations layer on more tools to gain insights into application usage and performance, they incur additional technical debt, making it harder to streamline operations or gain a full, real-time view of application behaviors — the type of insights required for so many businesses to succeed today.
• Inconsistent user authentication and access control. In a world of single-sign-on experiences, many organizations use a variety of authentication methods across different applications and environments, creating friction for users and complicating IT management. Maintaining multiple authentication systems becomes costly and cumbersome for all involved, especially as cybersecurity demands for zero trust and strong authentication grow. Worse yet are the remaining systems with their own separate user accounts and passwords divorced from any systemic approaches. 
• Fragmented compliance and data sovereignty controls. As organizations expand globally, ensuring data privacy and regulatory compliance becomes more complex. Many legacy systems and app delivery solutions are ill-equipped to meet the requirements of modern data sovereignty laws without heavy customization and additional layers of governance tools. 

As a result, organizations find themselves in a continuous cycle of patching and workaround solutions for application access and security, making it increasingly challenging to achieve true modernization and efficiency across their systems.

Application access tech debt has a significant impact on organizations

Application access technical debt can quietly erode the foundations of an organization, creating hidden costs and operational inefficiencies that multiply over time. As organizations build up layers of technology to meet new demands, complexity grows — taking a toll on productivity, security, and profitability.

• Increased complexity and costs: Over time, one-off application access solutions accumulate, creating an intricate and cumbersome tech stack. The mounting cost of maintaining and securing this patchwork strains IT budgets and diverts funds from innovation.
• Inefficiency and wasted resources: Technical debt limits an organization’s ability to adapt and innovate, as outdated systems often require extensive manual workarounds. Employees are forced to navigate inefficient processes and endure slowed workflows, reducing their productivity.
• Security risks: When tech debt accumulates within application access systems, the likelihood of vulnerabilities grows, exposing the organization to a higher risk of security breaches. Legacy infrastructure may lack the flexibility needed to integrate modern security protocols, and patches may be unavailable for unsupported older platforms, leaving gaps that malicious actors can exploit.
• Scalability constraints: Outdated technologies and lack of integration across tools can severely limit scalability, impeding an organization’s ability to grow and adapt to new demands. As digital transformation initiatives accelerate, application access technical debt can create barriers that prevent seamless expansion and cloud integration.
• Employee burnout: Application access technical debt contributes to inefficiencies and frustration among employees. Working with outdated, sluggish systems can impact morale and lead to burnout as employees face repetitive, manual tasks that could be automated or made simpler if systems were modernized.

It’s clear that application access tech debt is an urgent issue for IT and cybersecurity executives. But 30+ years into dealing with the tech debt challenge, what can leaders do?

How organizations can tackle application access tech debt

To effectively tackle application access technical debt, IT and cybersecurity leaders should first reframe it for their own leadership as not merely as a technical challenge but as a barrier to sustainable innovation. After all, if IT professionals had infinite time and money on their hands, tech debt would not be a problem — so, tackling it will require a conversation around budgets and willingness to stomach change that could be painful temporarily but worthwhile in the long run. And business leaders are more likely to invest in addressing technical debt if they understand it as a driver of operational efficiency and continuous improvement, rather than simply an IT issue.

Even better, business leaders will be more open to the idea of finally tackling application access tech debt when they realize that the answer to many of their issues may lie in a single, unexpected place: the browser. You heard it right — redesigning an organization’s tech stack around a singular solution for access, visibility, and security can revolutionize application access and demolish technical debt.

Your unexpected ally in reducing application access tech debt: the Enterprise Browser 

Why is a browser the place to address application access? Today, the browser serves as the central hub for nearly all enterprise work, connecting users to SaaS platforms, internal applications, and digital workflows. This wasn’t true 20 years ago, but as applications migrated to the cloud, the browser transformed from a basic web viewer into the primary interface for business operations.

Consumer browsers, such as Chrome and Edge, were not designed with enterprise security, compliance, or governance in mind; they simply render web content and leave the heavy lifting of security and access management to layers of auxiliary technologies — a complex and fragile stack of tech debt creating friction-filled user experiences. However, the limitations of consumer browsers extend beyond the browser itself; they also leave organizations reliant on legacy thick-client applications and outdated architectures that aren't optimized for modern web-based workflows, further compounding technical debt and hindering digital transformation efforts.

By contrast, an enterprise browser is purpose-built to meet modern business demands at the endpoint itself — natively embedding security, governance, and performance capabilities and allowing IT teams to eliminate layers of redundant tools. 

The Island Enterprise Browser is leading the charge. It streamlines the application access tech stack required to secure, manage, and enable access to applications — enabling faster, more efficient access to applications and data, and slashing complexity in the process.

The Enterprise Browser eliminates the need for the legacy tools that make up the majority of application tech debt. When employees access their applications instantly and securely via the Enterprise Browser, organizations can significantly reduce (or altogether eliminate) VDI, VPNs, DLP, CASB, proxies, secure service edge, SSL break and inspect mechanics, and a variety of endpoint agents, dramatically streamlining IT infrastructure.

In terms of security and observability, the Enterprise Browser embeds visibility and monitoring capabilities within the browser, reducing the need for the add-on tools associated with traditional network-based observability. Monitoring of application behaviors and user actions are likewise improved via real-time, context-rich insights directly from the browser, in contrast to traditional methods that monitor traffic in an attempt to reconstruct the application workflow. With the Island Enterprise Browser, IT and security teams have true last-mile control.

This isn’t your ordinary browser. The Island Enterprise Browser is purpose-built for the modern enterprise to provide a secure, observable application access environment. No debt required.
