Okta vs VPN vs Enterprise Browser: What's the Right Way to Onboard Contractors?

The contractor onboarding landscape of 2026 has exposed a fundamental security dilemma: organizations need to grant contractors access to SaaS applications and internal resources, but traditional approaches like Okta SSO and VPNs create significant security risks, compliance challenges, and operational friction. As organizations navigate this landscape, they're discovering that enterprise browsers provide the right way to onboard contractors—combining identity management, network security, and session-level controls in a single, browser-native solution.

In this comprehensive comparison of Okta vs VPN vs Enterprise Browser for contractor onboarding, we'll examine VPN risks, Okta limitations, unmanaged device challenges, and how enterprise browsers like Kahana Oasis solve contractor onboarding comprehensively, revealing why browser-native security is essential for secure third-party access in 2026.

Quick Verdict: The Contractor Onboarding Challenge

After extensive analysis of contractor onboarding approaches in 2026, the verdict reveals critical gaps:

• Okta Alone: Provides identity management and SSO but cannot enforce session-level controls, prevent data exfiltration, or secure unmanaged devices effectively.
• VPN Access: Creates broad network access, backdoor vulnerabilities, and compliance risks that make third-party VPN connections a top security concern.
• Kahana Oasis: The only enterprise browser that combines Okta SSO integration with browser-native security, enabling secure contractor onboarding "in minutes" with granular, session-level controls.

The VPN Risk Crisis: Why Third-Party VPN Access Is Dangerous

VPN access has become one of the most significant security risks for contractor onboarding, creating broad network access and backdoor vulnerabilities that attackers can exploit. Zscaler's ThreatLabz 2025 VPN Risk Report summarizes a global survey where most organizations see VPNs as a top security and compliance challenge, with strong concerns about backdoor vulnerabilities created by third-party VPN connections. This reveals a fundamental problem: VPNs grant contractors broad network access that extends far beyond what they need to perform their work, creating attack surfaces that are difficult to monitor and control.

Zscaler's 2024 VPN Risk Report provides a deep-dive analysis showing 92% of respondents worry about third-party VPN access as an entry point for attacks, and that VPNs make it hard and time-consuming to safely provide access for vendors and contractors. This reveals a critical challenge: VPNs require complex configuration, ongoing maintenance, and create security risks that are difficult to mitigate, especially for short-term contractors who may only need access for weeks or months.

The VPN risk extends beyond network access—VPN credentials can be stolen and abused even when MFA is in place. BreachSense's Okta breach case study shows how a third-party support contractor's VPN credentials were abused to reach Okta's internal tools, highlighting the risks of vendor VPN access and session token theft even with MFA in place. This reveals a fundamental vulnerability: VPN access creates persistent network connections that attackers can exploit, even when identity providers authenticate users successfully.

Oasis addresses VPN risks by eliminating the need for VPN access entirely. Unlike VPNs that grant broad network access, Oasis provides browser-native access to SaaS applications with granular, session-level controls that prevent data exfiltration and unauthorized access—all without creating network-level vulnerabilities.

Okta Limitations: Why Identity Management Alone Isn't Enough

Okta provides robust identity management and SSO capabilities, but it cannot secure contractor access comprehensively without additional security controls. Okta's Secure Sign-in Trends Report 2024 emphasizes the difficulty of enforcing phishing-resistant MFA and least privilege across diverse users like contractors. This reveals a fundamental gap: identity providers can authenticate contractors and assign groups, but they cannot enforce granular permissions within SaaS sessions or prevent data exfiltration after authentication succeeds.

Okta's Secure By Design commitment explains Okta's push to enforce MFA for all administrative access and the complexity of securing privileged accounts accessed via federated IdPs and PAM tools, which becomes harder with third-party users. This reveals a critical challenge: even when organizations deploy robust identity management, contractors accessing SaaS applications create security risks that identity providers cannot address—particularly around session-level controls and browser-level threats.

Okta's Business at Work 2024 report highlights how organizations rely on Okta to authenticate employees, contractors, and partners into SaaS apps, underscoring challenges of maintaining consistent security policies across mixed workforces. However, maintaining consistent policies is only part of the challenge—organizations also need session-level controls that identity providers cannot deliver.

Oasis addresses Okta limitations by providing browser-native security that complements identity management. Unlike Okta that manages authentication but not sessions, Oasis protects the entire browser session lifecycle, enforcing granular permissions, preventing data exfiltration, and providing comprehensive audit logging—all while integrating seamlessly with Okta SSO.

Unmanaged Devices: The BYOD Headache with Contractors

Unmanaged devices create one of the most significant challenges in contractor onboarding, as contractors typically use personal laptops and devices that organizations cannot manage or secure. Beyond Identity's analysis explains why traditional VPNs and MDM are flawed for contractors—broad network access, exploitable protocols, privacy concerns—and suggests passwordless, device-centric alternatives for third-party access. However, device-centric alternatives still require device management, which contractors won't allow for personal devices.

Omnissa's analysis discusses verifying unmanaged and third-party devices before app access, underscoring how tricky it is to balance strong device posture checks with frictionless access for contractors and partners. This reveals a fundamental tension: organizations need to verify device security, but contractors won't grant administrative access to personal devices, creating a security gap that traditional approaches cannot address.

Okta's 2024 Year in Review highlights new Okta capabilities like advanced device posture and SaaS access controls, framing the ongoing struggle to secure heterogeneous devices (including contractors' laptops) without blocking productivity. However, device posture checks require device management, which doesn't work for contractor BYOD scenarios.

Oasis addresses unmanaged device challenges through browser-native security that works regardless of device management status. Unlike VPNs that require device-level configuration, or identity providers that require device management for comprehensive security, Oasis provides browser-level security that enables secure contractor access on unmanaged devices without requiring administrative access or device management.

Session Token Theft: The Hidden Risk in Contractor Access

Session token theft creates a critical security risk in contractor onboarding, as attackers can steal browser session tokens and bypass authentication even when MFA is in place. BreachSense's Okta breach case study explains how attackers stole Okta session tokens from HAR files, bypassed MFA, and shows why relying solely on an identity provider leaves blind spots around browser-level session hijacking and contractor access. This reveals a fundamental vulnerability: identity providers authenticate users, but they cannot protect browser sessions from token theft or session hijacking attacks.

Session token theft is particularly dangerous for contractors because they often access SaaS applications from unmanaged devices on untrusted networks, creating opportunities for attackers to intercept session tokens through man-in-the-middle attacks, malicious browser extensions, or compromised networks. When contractors access SaaS applications through VPNs or standard browsers, their session tokens are exposed to these risks.

Oasis addresses session token theft through browser-native security that protects session tokens from interception and hijacking. Unlike standard browsers that expose session tokens to network-level attacks, Oasis provides session-level protection that prevents token theft and enforces continuous verification throughout the session lifecycle.

Over-Privileged Access: The VPN Network Access Problem

VPN access creates over-privileged access by granting contractors broad network access that extends far beyond what they need to perform their work. When contractors connect via VPN, they gain access to internal network resources, file shares, databases, and other systems that they may not need—creating attack surfaces that are difficult to monitor and control.

Security.org's 2025 VPN Trends report presents declining VPN usage and evolving user attitudes, which you can leverage to argue that legacy VPNs are out of step with modern security expectations and flexible contractor work patterns. This reveals a fundamental shift: organizations are moving away from VPNs because they create over-privileged access that violates least-privilege principles and creates security risks.

Oasis addresses over-privileged access by providing granular, application-level access controls that enforce least-privilege principles. Unlike VPNs that grant broad network access, Oasis provides browser-native access to specific SaaS applications with granular permissions that prevent unauthorized access to internal resources or data.

Tech Debt and User Friction: The VPN Maintenance Burden

VPN access creates significant tech debt and user friction, requiring complex configuration, ongoing maintenance, and troubleshooting that slows down contractor onboarding and creates operational overhead. TechRadar Pro's analysis describes how legacy tools like VPN and VDI create friction and tech debt, and how enterprise browsers can centralize controls for SaaS access, closing visibility gaps that are especially acute with contractors.

VPN maintenance creates multiple operational challenges: VPN clients must be installed and configured on contractor devices, VPN credentials must be managed and rotated, VPN connections must be monitored and troubleshooted, and VPN access must be revoked when contracts end. This creates significant overhead for IT teams managing contractor access.

Oasis addresses tech debt and user friction by providing browser-native access that requires no client installation, no VPN configuration, and no network-level management. Contractors can access SaaS applications through Oasis "in minutes" without complex setup or ongoing maintenance, reducing operational overhead and improving user experience.

Lack of Visibility: The Contractor Activity Blind Spot

Traditional approaches create significant visibility gaps in contractor activity, making it difficult to monitor what contractors are doing within SaaS applications or detect suspicious behavior. When contractors access SaaS applications through VPNs or standard browsers, organizations have limited visibility into session activity, data access, or potential security risks.

Island's enterprise browser positioning highlights how enterprise browsers can onboard third-party contractors "in minutes" with granular, session-level controls, directly surfacing pain points around data leakage and lack of visibility in traditional models. This reveals a critical capability: enterprise browsers provide comprehensive visibility into contractor activity that VPNs and identity providers cannot deliver.

Oasis addresses visibility gaps through comprehensive audit logging and session monitoring that provide complete visibility into contractor activity. Unlike VPNs that can only log network connections, or identity providers that can only log authentication events, Oasis provides detailed audit logs of all browser-level actions, enabling organizations to monitor contractor activity and detect security risks.

Enterprise Browsers: The Right Way to Onboard Contractors

Enterprise browsers provide the right way to onboard contractors by combining identity management, network security, and session-level controls in a single, browser-native solution. Island's SaaS Security blog explores threats like compromised credentials and SaaS data leakage, arguing that embedding controls in the browser is a more effective, user-friendly way to secure contractors' SaaS access than agents or VPNs.

Enterprise browsers address the fundamental challenges of contractor onboarding: they provide browser-native access to SaaS applications without VPNs, they enforce granular permissions within sessions, they work on unmanaged devices without device management, they provide comprehensive audit logging, and they enable rapid onboarding "in minutes" without complex configuration or ongoing maintenance.

Unlike VPNs that grant broad network access, enterprise browsers provide application-level access with granular controls. Unlike identity providers that manage authentication but not sessions, enterprise browsers protect the entire session lifecycle. Unlike device management tools that require administrative access, enterprise browsers work on unmanaged devices without device-level configuration.
