SecureLint Enterprise Browser DLP: Secret Masking, Email DLP & Threat Intelligence (2026)

Traditional enterprise DLP tools were built for a world where sensitive data lived on file servers and moved through email gateways. In 2026, sensitive data lives in browser tabs — SaaS dashboards, cloud consoles, web-based IDEs, and collaborative documentation tools. SecureLint Enterprise was built for this world: a browser-native DLP and threat protection platform that enforces policies at the point where data actually flows, without requiring endpoint agents, network proxies, or MDM configuration.

SecureLint Enterprise overview

SecureLint Enterprise extends the individual SecureLint extension with a centralized policy engine, admin console, and integrations layer. The architecture is simple:

• The SecureLint Chrome extension is deployed to every employee browser — via Chrome Web Store managed deployment, Chrome Enterprise, or manual IT distribution
• The SecureLint admin console (web-based, no installation) is where IT and security teams define policies, review detection events, manage extension inventory, and configure SIEM integrations
• Policies are synced to the extension in the background — employees do not need to do anything for policies to take effect
• Detection events are forwarded to the admin console and optionally to your SIEM in real time

No endpoint agent. No network proxy. No VPN. The extension is the enforcement point.

Team-wide DLP policy engine

The policy engine lets admins define rules that apply to every employee browser where SecureLint is installed. Available policy types:

• Credential masking enforcement — Make secret masking mandatory across all inputs on all pages, preventing employees from disabling it
• Site-specific masking — Enforce masking only on specific high-risk domains (e.g. always mask on *.notion.so and *.confluence.atlassian.net)
• Meeting Mode enforcement — Automatically activate Meeting Mode whenever a video call is detected, with no employee override
• Clipboard monitoring — Log when credential patterns are copied to the clipboard, with optional alert on paste to unapproved destinations
• Upload blocking — Prevent uploads of files matching sensitive patterns (API key exports, private key files) to non-approved cloud storage

Email DLP: blocking credential sends in Gmail and Outlook

One of the most impactful enterprise features is Email DLP — the ability to detect and block outgoing emails containing API keys, passwords, and other credentials before they leave the organisation.

How it works:

1. SecureLint monitors the email composition window in Gmail and Outlook Web in real time
2. When a credential pattern is detected in the email body, subject, or as part of an attachment filename, SecureLint flags the send action
3. Clicking Send shows a policy violation dialog listing the detected credential type and location
4. The email cannot be sent until the credential is removed — or an admin approves an override
5. All detected violations and override events are logged to the admin console with full message context (recipient domain, detected pattern type, timestamp)

Admin dashboard and detection events

The SecureLint admin console provides real-time visibility across your entire workforce's browser activity:

• Detection event feed — All policy violations, malicious extension detections, phishing page visits, and blocked navigations in a single, filterable feed
• Per-user activity — Drill into any employee to see their extension inventory, recent detection events, and current policy compliance status
• Credential exposure reports — Weekly and monthly reports showing which credential types were detected, which domains they appeared on, and trend data
• Extension inventory — Real-time list of every extension installed across your workforce with risk scores, permission summaries, and update history
• Policy audit log — A complete log of all policy changes with the admin identity, timestamp, and change details

Enterprise extension management

SecureLint Enterprise provides browser-agnostic extension management — no Chrome Enterprise enrollment or Group Policy required:

• Define an allowlist of approved extensions by extension ID — anything not on the list is blocked and disabled
• Maintain a blocklist of explicitly prohibited extensions for high-risk or known-malicious tools
• Configure alert thresholds for permission risk scores — extensions exceeding the threshold trigger a detection event for admin review
• Track ownership changes and extension updates across your workforce in real time

Threat intelligence and phishing protection

SecureLint Enterprise inherits all individual-plan threat protection features and enhances them with team-level threat intelligence:

• Shared phishing domain blocklists — Add domains to your organisation's blocklist; they are blocked for all employees immediately
• Category-based blocking — Enable block-by-category for Phishing, Malware Distribution, Crypto Drainers, and Brand Impersonation domains
• Threat intelligence feed subscriptions — Subscribe to industry-specific threat feeds (financial services, healthcare, government) for tailored domain blocking
• Team phishing simulation integration — SecureLint can integrate with your phishing simulation platform to exclude simulation domains from blocking and to log simulation click events separately

SIEM and SOAR integration

Every detection event in SecureLint Enterprise can be forwarded to your existing security infrastructure in real time:

• Webhooks — POST events to any endpoint in real time. Configurable per event type and severity. Supports custom headers for authentication.
• REST API — Query events, users, extension inventory, and policy status programmatically. Supports filtering, pagination, and date-range queries.
• Native connectors — Pre-built integrations for Splunk, Datadog, Elastic SIEM, and PagerDuty with field mapping and alert rule templates.

All events are emitted in a standardised JSON schema. Each event includes: event type, severity, employee identity, browser context (URL, tab title), detection details (pattern type, matched value type — never the actual secret), and timestamp.
