The Top 8 Alternatives To Island (2026)

• Focuses on protecting against identity-based attacks in the browser, including adversary-in-the-middle phishing, device code phishing, session hijacking, credential theft, malicious extensions, and malicious OAuth grants
• Provides identity hardening reports on weak, reused, and leaked passwords, accounts missing MFA, and logins that bypass SSO entirely
• Offers data controls for file uploads and downloads, clipboard contents matched with regular expressions, and category-level app and domain blocking alongside AI governance features
• Inventories and blocks extensions with rules that can target permission scope, rather than named extensions

If you’re looking for an alternative to Island to protect against browser-based attacks, unauthorized AI usage, and shadow SaaS, then Push Security is a really strong solution to consider. We particularly recommend it for organizations using contractors or with BYOD users in their workforce, where a managed browser rollout might be impractical. You can also run Push inside Island, which is worth knowing if you plan to keep Island for a specific user group, but want to be able to apply secure browser controls everywhere else.

• DLP controls cover clipboard restrictions, upload and download blocking, watermarking, screen capture prevention, and print controls at the browser level
• Anti-keylogging and web filtering add extra protection layers
• Citrix Adaptive Authentication enables context-aware policy enforcement based on device posture, network location, and user identity
• Integration with Google Chrome Enterprise Premium extends DLP and zero trust controls to unmanaged devices

We think Citrix Enterprise Browser fits best as a dedicated secure browser for high-risk users or sensitive applications rather than a full fleet replacement. If your organization already runs Citrix Workspace, this extends your existing investment with strong security controls. For teams outside the Citrix ecosystem, standalone enterprise browsers offer more flexibility.

• Total Cookie Protection partitions cookies so each website gets its own isolated cookie jar, the strongest anti-tracking default of any mainstream browser
• DNS over HTTPS encrypts DNS queries with safeguards to prevent overriding DNS-based filtering on managed networks
• Policy management supports ADM/ADMX templates on Windows, PLIST on macOS, and JSON files on Linux, with approximately 150 policies available
• Two update tracks: ESR for stability with major updates yearly, or Rapid Release for four-week feature cycles

We think Firefox for Enterprise fits privacy-conscious organizations that need cross-platform policy management without locking into a proprietary browser ecosystem. If your environment depends heavily on web apps with complex cookie behavior, plan for some initial compatibility tuning. The ESR track is well suited for organizations that prioritize stability over frequent feature updates.

• Free core tier covers policy configuration, extension management, and reporting across all devices from a single console
• Paid Premium tier adds DLP controls, malware deep scanning (including large and encrypted files up to 2GB), URL filtering, and context-aware access based on device security posture
• Work and personal profile separation keeps business browsing isolated, without requiring a second browser
• Over 600 policies available for granular configuration

We think the free tier handles basic policy needs well, but most security teams will want the paid Premium features for DLP, malware scanning, and URL filtering. The familiar Chrome interface minimizes end-user training and support overhead. Outside the Google ecosystem, the value proposition is less compelling compared to browser-agnostic enterprise security options.

• Scans web elements in real time to catch zero-day threats, blocks phishing pages before credentials get harvested, and monitors data movement across SaaS apps
• GenAI controls prevent users from pasting sensitive code or PII into LLM prompts, with granular rules based on user role, access location, and actions taken
• Shadow IT discovery maps unauthorized application usage and flags data leakage paths across the organization
• Supports Chrome, Edge, Firefox, Safari, Brave, and Arc

We think LayerX works best for organizations dealing with SaaS sprawl, GenAI data exposure risks, or BYOD access scenarios. If you need browser-layer security without forcing a browser migration, this is a strong option. The zero-migration deployment and GenAI DLP controls are strong differentiators in the enterprise browser category.

• Connects natively to Microsoft Entra Conditional Access for role-based resource controls and Microsoft Defender SmartScreen for phishing and malware protection
• Copilot AI in the sidebar queries both web data and internal Microsoft 365 files; Agent Mode automates multi-step workflows across up to 30 open tabs
• Edge Workspaces let teams share browser tabs, windows, and files in a shared workspace
• Enterprise data protections apply as long as users are signed in with their Entra ID, whether the device is managed or unmanaged

We think Edge for Business fits best for enterprises in regulated industries where Entra Conditional Access and Defender SmartScreen address compliance requirements directly. The Copilot AI features and Agent Mode add genuine productivity value for teams working across Microsoft 365 apps. For organizations not committed to the Microsoft ecosystem, the differentiation thins out quickly.

• Site access, file downloads, copy/paste behavior, and upload restrictions managed from a single console
• DLP controls extend to generative AI applications, preventing sensitive data leakage through AI prompts and autonomous agent interactions
• BYOD and contractor use case well-served; push policies to the browser instead of provisioning VDI or shipping corporate laptops
• Integration with the broader Palo Alto ecosystem, including Cortex and Panorama

We think Prisma Access Browser fits enterprises already invested in the Palo Alto ecosystem with distributed workforces, heavy contractor use, or BYOD environments where endpoint control isn’t practical. The agentic AI security features are a forward-looking differentiator. Expect a tuning period upfront, but the policy engine is powerful once dialed in. Teams outside the Palo Alto ecosystem should weigh the vendor commitment carefully.

• JavaScript engine integration intercepts browser operations before threats execute, catching phishing, zero-day exploits, clickjacking, and web-based malware in real time
• DLP controls disable copy and paste on sensitive sites, apply content filtering, and manage identity-based access rules
• Automatic multi-browser discovery on endpoints starts protecting all installed browsers without heavy configuration
• Integration with existing SSO, EDR, and SIEM tools slots into your stack without requiring changes

We think Seraphic fits mid-market to enterprise teams, especially those managing mixed browser environments or BYOD access. The JavaScript engine integration gives it a detection advantage that surface-level extensions can’t match. The CrowdStrike acquisition is significant; buyers should clarify with CrowdStrike how the product will be integrated and whether standalone availability will continue.
