Beyond the Sprawl: How to Simplify Access Management at Scale

Welcome to the APPocalypse

IT and security teams are drowning in a sea of apps, identities, and permissions—and it’s only getting worse. The rapid shift to SaaS, remote work, and cloud-first everything has turned access management into a tangled mess. Every department adopts its own tools, users accumulate unnecessary permissions, and security teams struggle to keep up with the ever-growing complexity of access management.

The result? A crisis of access sprawl—where organizations lose visibility and control over who has access to what, creating security risks, compliance nightmares, and operational chaos. Traditional identity and access management (IAM) strategies can’t keep up, leaving teams overwhelmed and attackers with far too many opportunities.

So, how did we get here? Why are existing security approaches failing? And most importantly—what can IT and security teams do to take back control? In this article, we’ll break it all down and explore how organizations can survive the APPocalypse.

The Rise of Access Sprawl: How We Got Here

Access sprawl didn’t happen overnight—it’s the result of a perfect storm of trends that reshaped how businesses operate. The explosion of SaaS apps, remote work, and an ever-growing list of users needing access has overwhelmed traditional identity and access management (IAM) strategies. IT and security teams are now stuck trying to control a system that was never designed to scale this fast.

Let’s break down how we got here.

More Apps, Less Visibility

It used to be that IT controlled which software made it into an organization. Not anymore. The rise of SaaS has made it easy for every department to adopt its own tools—often without security oversight.

• The Shift to SaaS: HR, finance, marketing, engineering—everyone has their own stack of apps. Need a new tool? Just swipe the corporate credit card and go. IT only finds out after something breaks, or worse, after a security incident.
• Shadow IT: Security teams can’t protect what they don’t know exists. Employees regularly sign up for tools that store sensitive data, but without proper visibility, IT has no way of ensuring those apps are secure.
• The Permission Tracking Nightmare: Every app has its own set of roles, permissions, and access levels. Multiply that across hundreds of platforms, and suddenly, tracking who has access to what becomes impossible.

Without centralized control, organizations lose visibility over their access landscape. And if you can’t see it, you definitely can’t secure it.

Identity Explosion: More Users, More Devices, More Access

It’s not just the apps—it’s the people (and machines) accessing them. The modern workforce is more distributed than ever, and every user comes with a new set of permissions that need to be managed. Employees, contractors, and third-party vendors all require access to various systems, but when people leave, their permissions aren’t always revoked, leaving behind forgotten (but still active) accounts that create unnecessary security risks.

Hybrid work has only added to the complexity. Employees now log in from personal devices, home networks, and public Wi-Fi, forcing security teams to consider not just who is accessing a system, but from where and on what device. And it’s not just human users—machines need access too. Automated workflows, cloud services, and integrations rely on service accounts, bots, and API keys, many of which are over-permissioned, rarely rotated, and prime targets for attackers.

With every new identity, device, and permission, the attack surface expands. And right now, that attack surface is massive.

Why Traditional IAM & IT Approaches Aren’t Cutting It

Security teams have been fighting access sprawl using the same tools and strategies for years—but they weren’t built for today’s pace of change.

• Manual Access Reviews: Most organizations still rely on periodic access reviews to check who has what. These reviews are tedious, prone to human error, and by the time they’re completed, the access landscape has already changed again.
• Role-Based Access Control (RBAC) Struggles: RBAC was supposed to simplify access management by defining roles with pre-set permissions. But modern workflows don’t fit neatly into static roles, leading to role explosion—where users accumulate roles they no longer need.
• Over-Permissioning as the Default: It’s easier to just give users “temporary” elevated access rather than dealing with constant requests. The problem? Those permissions are rarely revoked, turning temporary into permanent.

The end result? Organizations are left with too many apps, too many identities, and too many permissions to manage manually. And that’s exactly why access sprawl has spiraled into an unmanageable crisis.

So what happens when this chaos is left unchecked? Let’s talk about the risks.

The Risks of Unchecked Access Sprawl

Access sprawl isn’t just an inconvenience—it’s a serious security and operational liability. When organizations lose track of who has access to what, they open the door to cyber threats, compliance failures, and endless operational headaches. Here’s what happens when access sprawl is left unchecked.

Security Nightmares: The Expanding Attack Surface

Every unnecessary permission is a potential entry point for attackers. As users accumulate excessive access over time, the organization’s attack surface expands, increasing the risk of security breaches. Over-permissioned accounts are particularly valuable to hackers—a single compromised credential with excessive access can provide direct entry into critical systems, making privilege escalation an easy next step.

Beyond external threats, insider risks are also on the rise. The more people with access to sensitive data, the greater the chances of intentional misuse or accidental leaks. Whether through negligence or malicious intent, insider threats pose a significant challenge for security teams trying to maintain control over access.

Compliance is another major concern. Regulatory frameworks like SOC 2, HIPAA, and ISO 27001 require strict access controls, but without clear oversight, organizations struggle to meet these requirements. The result? Failed audits, hefty fines, and a loss of customer trust—all because of unmanaged access sprawl.

Operational Chaos: The IT & Security Drain

Even if access sprawl doesn’t lead to a security incident, it still creates a massive operational burden for IT and security teams.

• The Never-Ending Cycle of Access Requests: Every day, IT teams field a flood of access requests, approvals, and deprovisioning tasks—most of which could be automated but aren’t.
• Manual Audits & Entitlement Reviews: Compliance teams require periodic reviews of user access, but doing this manually across hundreds of apps is a painful, slow, and error-prone process.
• Burnout Is Real: Security teams are already stretched thin. When they’re constantly drowning in identity-related tasks, they have less time for proactive security initiatives—leading to higher turnover and increased organizational risk.

The Business Cost of Access Mismanagement

Beyond security and IT, access sprawl directly impacts business operations, slowing teams down and introducing unnecessary costs. Unauthorized access can lead to data leaks, regulatory fines, and reputational damage, with the average cost of a data breach in the US reaching $9.48 million in 2024—a financial hit no organization wants to take.

Inefficiency also takes a toll on productivity. Employees waiting for access, or worse, losing access at critical moments, experience frustrating delays that disrupt workflows. When security becomes a bottleneck rather than an enabler, business operations suffer.

The financial impact extends beyond breaches and lost productivity. Companies invest heavily in security tools and compliance programs, yet poor access management leads to wasted resources, redundant software licenses, and unnecessary overhead. What should be a streamlined, secure process instead becomes a drain on both time and budget.

Access sprawl isn’t just an IT problem—it’s a business-wide crisis. So, how do organizations regain control? Let’s talk solutions.

Regaining Control: How IT & Security Teams Can Fight Back

Access sprawl might feel like an unstoppable force, but IT and security teams can regain control. The key? Ditching outdated approaches and adopting smarter, risk-based strategies that prioritize security without slowing down the business. Here’s how to fight back.

Embrace a Risk-Based Approach to Access

Traditional access management operates on a "set it and forget it" model—users get permissions once and keep them indefinitely. But in today’s fast-moving environment, that’s a recipe for disaster. Instead, organizations need to adopt a risk-based approach that continuously evaluates access needs.

• Stop Hoarding Permissions: Not all access is created equal. Focus on protecting critical assets first and enforcing least privilege—ensuring users only have the access they actually need.
• Move Beyond Static Role-Based Access Control (RBAC): Instead of rigid roles, organizations should leverage attribute-based access control (ABAC) or policy-based access control (PBAC), which dynamically adjusts permissions based on real-time conditions.
• Continuous Access Reviews: Instead of painful, once-a-year access audits, automate continuous access reviews based on actual usage data—revoking access when it’s no longer needed.

Automate Identity & Access Management (IAM)

If IT and security teams are manually approving access requests, provisioning users, and deprovisioning stale accounts, they’re fighting a losing battle. Automation is the only way forward.

• Use AI to Reduce Manual Workloads: AI-driven identity governance and AI access control can automate low-risk approvals and flag high-risk access changes, ensuring security teams focus only on the exceptions.
• Automate Provisioning & Deprovisioning: Employee joins? Automatically grant appropriate access based on role. Employee leaves? Instantly revoke all permissions. No more orphaned accounts lurking in the shadows.
• Intelligent Access Requests: Instead of relying on gut instinct, organizations should implement risk-based access requests—automatically approving low-risk requests while escalating high-risk ones for human review.

Implement Just-in-Time (JIT) and Zero Standing Privileges (ZSP)

One of the biggest security risks is always-on access—where users retain elevated privileges even when they don’t need them. This creates an unnecessary attack surface and increases the risk of abuse.

• JIT Access: Grant users access only when they need it—and revoke it as soon as the task is complete.
• Zero Standing Privileges (ZSP): No one should have permanent admin rights. Instead, use ephemeral access that requires authentication and approval every time elevated privileges are needed.
• Reduce the Attack Surface by Default: By eliminating unnecessary persistent access, organizations automatically reduce the risk of credential theft, insider threats, and privilege misuse.

Make Security a Business Enabler, Not a Roadblock

Security shouldn’t be a bottleneck—it should empower the business. The best IAM strategies make access management seamless for end users while maintaining strong security controls.

• Simplify Access Without Compromising Security: Implement self-service access with security guardrails, so employees can get what they need without waiting on IT.
• Align Security With Business Goals: If security slows down productivity, it won’t get leadership support. IAM solutions should be positioned as business enablers—boosting efficiency while reducing risk.
• Demonstrate Measurable Wins: Security leaders should showcase the impact of access automation, reduced attack surface, and faster provisioning to justify continued investment in IAM solutions.

Regaining control over access sprawl is about security—but also efficiency, compliance, and long-term resilience. Organizations that take a proactive approach now will be the ones that stay ahead of the APPocalypse.

Up next: the future of access management—and how to prepare for it.

The Future of Access Management

Access sprawl isn’t going away—it’s only getting worse. As businesses continue adopting more apps, expanding their workforce, and embracing hybrid work, the complexity of managing identities and permissions will keep growing. Organizations that ignore this reality will find themselves drowning in security risks, operational inefficiencies, and compliance failures.

The only way forward is a proactive, automated approach to access management. IT and security teams need the right tools to streamline access controls, enforce least privilege, and eliminate unnecessary permissions—without creating bottlenecks for the business.
