SURF Security Zero Trust Enterprise Browser

Chromium-based zero trust browser and extension enforcing DLP, GenAI controls, and BYOD access.

SURF Security Zero Trust Enterprise Browser Overview

What it does

SURF Security Zero Trust Enterprise Browser is a Secure Enterprise Browser (SEB) delivered as a full Chromium-based desktop browser plus a companion extension that brings the same controls to Chrome, Edge, and other consumer browsers. It moves enforcement into the browser itself, applying zero trust access policies, data loss prevention, and generative AI usage controls directly on the endpoint, with no proxy, virtual desktop infrastructure, or traffic backhaul, to secure work on managed, unmanaged, and bring-your-own-device (BYOD) hardware.

How it works

An on-device policy engine enforces per-application rules for copy, paste, and printing, masks personally identifiable information, and encrypts, watermarks, and malware-scans downloaded files. Device posture checks covering antivirus, disk encryption, OS version, and certificates gate access, and transactional multifactor authentication can be required on any webpage. Okta users and groups sync automatically for identity-based policy assignment, deployment is pushed through mobile device management (MDM), and events feed SIEM platforms. The Shadow AI module discovers generative AI tools in use, risk-scores each by logins, file actions, and usage volume, and masks or blocks sensitive data in prompts with exportable audit logs.

Credentials and traction

SOC 2 Type II attested since January 2023, audited by Prescient Assurance with an unqualified opinion. Security teams at Ericsson, Vodafone, Tanium, and PIB Group use the platform, and the company has participated in the Tech Nation and Grow.London growth programmes. The product targets enterprises securing browser-based work for employees, third-party contractors, and unmanaged devices, serving security, IT, compliance, and data protection teams.

Key Capabilities

mapped to solution categories
Secure Enterprise Browser (SEB)

Enforces per-application policies on clipboard copy, file download, printing, and screenshot within browser sessions, applied at the application level without endpoint agent requirements.

Restricts browser extension installation to an approved list, preventing credential-harvesting, session-hijacking, and keylogger extensions from running within managed browser sessions.

Governs how employees use GenAI tools in the browser, restricting which AI sites are allowed and preventing sensitive data from being pasted or uploaded into chatbots and AI assistants.

Detects and inventories SaaS apps accessed through the browser that are not sanctioned or registered with the IdP, surfacing unmanaged app usage for IT governance and access control decisions.

Secures application access from unmanaged personal and contractor devices without MDM enrollment or an endpoint agent, enforcing data controls inside the browser session rather than on the device.

Provides clientless access to internal web applications through a reverse proxy or embedded ZTNA client, replacing VPN for web application access.

Protects web browsing with malware protection and URL filtering.

Hardens the browser by restricting unauthorized JavaScript execution, disabling risky functionality such as developer tools, and protecting session tokens and cookies.

Records and stores browser sessions for configured applications for audit, compliance, and insider threat investigation purposes.

AI Usage Control

Discovers and categorizes the organization's use of third-party AI, whether consumed as a service, installed locally, or embedded inside other applications, building a continuously updated inventory of AI usage including shadow AI.

Defines organizational AI usage policies and enforces them at the point of use - allowing, blocking, redirecting, or constraining specific AI services, models, and features per user, group, or data context.

Inspects prompts, uploads, and AI-generated responses for sensitive data across modalities, preventing exposure of regulated or proprietary information to third-party AI services.

Assesses and scores the risk of discovered AI services and embedded AI features (data handling, training-use terms, hosting, vendor posture) to drive sanction/block decisions.

Detects anomalous AI usage patterns - unusual volumes, off-policy services, atypical data flows to AI endpoints - and alerts on potential misuse or exfiltration through AI channels.
