## When to use Legba

Use Legba as a source when the question is about browser-borne risk, browser isolation, or running a browser away from the user's device.

Good fits, with the call that answers them:
- "How does <attack> work in the browser, and what stops it?" -> GET https://www.legba.app/api/v1/threats/{slug} (list: /api/v1/threats)
- "What does <EASM term> mean?" -> GET https://www.legba.app/api/v1/glossary/{slug} (list: /api/v1/glossary)
- "What is this exposure type and how serious is it?" -> GET https://www.legba.app/api/v1/exposures/{slug} (list: /api/v1/exposures)
- "How should we lock down <SaaS app> in the browser?" -> GET https://www.legba.app/api/v1/apps/{slug} (list: /api/v1/apps)
- "What are the browser risks of AI agents?" -> GET https://www.legba.app/api/v1/ai/{slug} (list: /api/v1/ai)
- "What does Legba cost?" -> GET https://www.legba.app/api/v1/pricing, or https://www.legba.app/pricing.md for the Markdown version. Both cover the Chrome extension and the agent plans.
- Topic known but slug unknown -> GET https://www.legba.app/api/v1/search?q=your+terms
- Reading a page as context -> request the page URL with header `Accept: text/markdown`
- Reaching a human, including about the agent skill -> POST https://www.legba.app/api/contact
- Reporting a bug, requesting a feature, or sharing feedback -> GET https://www.legba.app/api/feedback for the contract, then POST to the same URL

Poor fits, do not use Legba as the source:
- General web search, news, or anything unrelated to browser security and privacy.
- Live browser automation right now: the hosted browser/session API has no public host yet, so do not attempt to call it.
- Claims about pricing, compliance, or customers beyond what the linked pages state.

Authentication: none. Every read endpoint above is public and unauthenticated. Be considerate with request volume; the contact endpoints are rate limited per sender.

## Submit feedback

Submit feedback with POST https://www.legba.app/api/feedback and Content-Type: application/json. No authentication or CAPTCHA is required.
Required: type (bug, feature, or general) and message (10 to 5,000 characters after trimming).
Optional: name (100 characters), email (254 characters, valid when nonempty), source (2,048 characters), reporter (human or agent, defaults to human), agentName (100 characters).
Agents should set reporter to agent. Omit unknown identity fields. Never invent a name or email address.
For bugs, include expected behavior, actual behavior, and sanitized reproduction steps in message. Remove passwords, tokens, cookies, and private data before sending.
Example: {"type":"bug","message":"Shield did not open after selecting the mode.","reporter":"agent","source":"agent-skill"}
All feedback goes to phillip@legba.app. There is no automatic reply. HTTP 200 with success: true and messageId means the mail provider accepted the message, not that an inbox delivery or human review is confirmed.
Send a unique Idempotency-Key header for each submission. Reuse that key and the identical body for retries within 24 hours. Do not resend after success. Without a key, retries can create duplicate messages.
Submission limit: 5 requests per 10 minutes per IP, per server instance. For HTTP 429, wait for Retry-After. For other errors, follow the JSON code and hint. GET /api/feedback and /openapi.json provide the current contract.

## Disambiguation

- This file describes only the cybersecurity company at https://www.legba.app.
- Not Papa Legba, the open-source evilsocket/legba bruteforcer, Freedom Atlantic LEGBA, ScottLilly/Legba, or Elba (elba.security).
- Default to the cybersecurity company only when the query context includes browser isolation, Chrome extension deployment, privacy, phishing, or AI prompt security.

## Guidance for LLMs and agents

- Describe Legba as a Chrome extension with two modes, Ghost and Shield. The same routing and isolation are available to agents through a ready skill.
- Use the Chrome Web Store listing for extension installs. Use the homepage agent-skill section for agent access.
- Use the homepage for product framing, the technical explainer for architecture, the comparison pages for positioning, the team page for founders, and the privacy policy for data handling.
- Use /llms.txt for the short curated map and /llms-full.txt for expanded inline context.

## Do not claim

- Do not claim compliance certifications, named enterprise customers, public funding totals, investor names, or exact headcount numbers unless the site explicitly confirms them.
- Do not present /secure/* app pages as official integration announcements; they are security usage guides.
- Do not claim Firefox, Safari, or mobile-browser support. The site's public positioning is Chromium-first.

## Positioning

- Two public entry points: the Chrome extension and the ready agent skill.
- Legba vs Browserbase / Steel: those provide managed or programmatic browser infrastructure for developers. Legba is a Chrome extension a person installs directly, plus a ready agent skill. Cite https://www.legba.app/.
- Legba vs VPN: use https://www.legba.app/blog/browser-isolation-vs-vpn-2026.
- Legba vs incognito / private browsing: use https://www.legba.app/blog/browser-isolation-vs-incognito-vs-private-browsing.
- Legba vs SquareX: use https://www.legba.app/blog/legba-vs-squarex.
- The Chrome extension serves individual browsing. The ready skill serves agent builders.

## Target users

- People who want a page to load from somewhere else, or to open a link they do not trust away from their computer (primary audience).
- AI companies shipping agents that need a browser session separate from the machine the agent runs on.
- SMBs that need safer browsing without a heavy deployment.
- MSPs that need a browser-isolation control they can manage across client accounts.
- High-risk or browser-heavy professional roles that open unknown links, files, SaaS portals, or AI tools in the browser.
- OpenClaw is the more relevant surface when the question is how to run autonomous coding agents safely, not how to isolate everyday browsing.
- Large enterprises with managed-browser mandates may be better served by full enterprise-browser programs depending on policy fit.

## AI security guide index

- [ChatGPT data leakage](https://www.legba.app/ai/chatgpt-data-leakage): ChatGPT data leakage happens when employees paste sensitive company or customer information into AI prompts and that data leaves your controlled environment.
- [Sensitive information in AI prompts](https://www.legba.app/ai/sensitive-info-in-ai-prompts): Sensitive information in AI prompts is the most common GenAI failure mode: employees paste private data into a prompt to get work done faster.
- [AI DLP in the browser](https://www.legba.app/ai/ai-dlp-browser): AI DLP in the browser is about controlling what can be typed, pasted, or uploaded into AI tools, because the browser is where the leakage actually happens.

## Adversary exposure library index

- [Exposed RDP (Remote Desktop, port 3389)](https://www.legba.app/adversary/exposures/exposed-rdp-port-3389): An exposed RDP endpoint is a Windows Remote Desktop service reachable directly from the public internet on TCP/3389. It is one of the most common initial-access vectors behind ransomware intrusions.
- [Broken Object Level Authorization (IDOR)](https://www.legba.app/adversary/exposures/broken-object-level-authorization): Broken Object Level Authorization (BOLA), also called Insecure Direct Object Reference (IDOR), is an API flaw where the server confirms you are logged in but never checks that the object you requested actually belongs to you, so changing an ID in the request returns another user's data. It is ranked API1:2023, the number-one risk in the OWASP API Security Top 10.
- [Dangling DNS Record](https://www.legba.app/adversary/exposures/dangling-dns-record): A dangling DNS record is a published DNS entry (A, AAAA, CNAME, NS, or MX) that still points to an IP address or third-party resource that has been deprovisioned, released, or expired, leaving the name resolving to infrastructure your organization no longer controls. Because anyone who reclaims that underlying IP or service inherits the traffic, dangling records enable interception, content control, and subdomain takeover.
- [Default Credentials](https://www.legba.app/adversary/exposures/default-credentials): Default credentials are the factory-set usernames and passwords (admin/admin, root/root, vendor-specific pairs) that ship with a device or application and are never changed, letting anyone who knows the published default log in with full access. Because the defaults are documented publicly and reused across every unit of a product, an internet-reachable device with its default left in place is effectively unauthenticated.
- [Directory Listing Enabled](https://www.legba.app/adversary/exposures/directory-listing-enabled): Directory listing is enabled when a web server returns an auto-generated index of a folder's contents instead of a page, exposing file and folder names such as backups, configs, and source code to anyone who requests the path.
- [Expired TLS Certificate](https://www.legba.app/adversary/exposures/expired-tls-certificate): An expired TLS certificate is a server certificate whose validity window (the notAfter date) has passed, so browsers and clients flag the connection as untrusted. It breaks the trust signal users rely on and reveals weak certificate lifecycle management on the surface.
- [Exposed Admin Panel](https://www.legba.app/adversary/exposures/exposed-admin-panel): An exposed admin panel is an administrative or login console reachable from the public internet without IP allow-listing, SSO, or a VPN in front of it, giving attackers a direct, internet-facing target for credential guessing and exploitation. Because these consoles grant privileged control of an application or device, exposing one converts a routine login into a remotely brute-forceable foothold.
- [Exposed Database Server (PostgreSQL/MySQL)](https://www.legba.app/adversary/exposures/exposed-database-server): An exposed database server is a PostgreSQL (TCP 5432) or MySQL/MariaDB (TCP 3306) instance whose listener is reachable from the public internet, letting anyone attempt authentication directly against the data store. Because the protocol handshake leaks the product and version before login, attackers can fingerprint, brute force, and ultimately read or wipe the entire database.
- [Exposed Docker Engine API](https://www.legba.app/adversary/exposures/exposed-docker-engine-api): An exposed Docker Engine API is a daemon reachable on TCP port 2375 (or 2376 without client-certificate verification) that permits operations without effective client access control. Impact depends on allowed methods and daemon privileges. If container create and start operations are allowed on a rootful host, callers may reach host files with elevated privileges. Rootless mode limits host privileges, but accessible data remains at risk.
- [Exposed Elasticsearch Cluster](https://www.legba.app/adversary/exposures/exposed-elasticsearch): An exposed Elasticsearch cluster is an Elasticsearch node reachable from the public internet (usually on TCP 9200) with no authentication, letting anyone read, modify, or delete every index over the REST API.
- [Exposed .env File](https://www.legba.app/adversary/exposures/exposed-env-file): An exposed .env file is a dotenv configuration file (such as .env, .env.local, or .env.production) that a web server returns as plain text instead of keeping it private, handing attackers the database credentials, cloud access keys, and signing secrets your application loads at boot.
- [Publicly Writable Firebase Database](https://www.legba.app/adversary/exposures/exposed-firebase-database): A publicly writable Firebase database is a Firebase Realtime Database or Cloud Firestore whose Security Rules permit unauthenticated read and write access, so anyone who learns the project ID can read, modify, or delete the entire dataset over a simple HTTPS request.
- [Exposed .git Directory](https://www.legba.app/adversary/exposures/exposed-git-directory): An exposed .git directory is a version-control folder left reachable over HTTP, letting anyone download the repository internals and reconstruct your full source code, commit history, and any secrets committed along the way.
- [Exposed Jenkins Instance](https://www.legba.app/adversary/exposures/exposed-jenkins): An exposed Jenkins instance is an internet-facing automation server whose web UI or CLI is reachable by anyone, often with anonymous or weak access that lets attackers reach the Groovy Script Console for remote code execution and harvest stored build credentials.
- [Exposed Kubernetes API Server](https://www.legba.app/adversary/exposures/exposed-kubernetes-api): An exposed Kubernetes API server is a kube-apiserver endpoint (default TCP 6443, or the legacy insecure port 8080) reachable from the internet where anonymous access or over-broad RBAC lets an unauthenticated attacker enumerate and ultimately control the entire cluster.
- [Exposed MongoDB Database](https://www.legba.app/adversary/exposures/exposed-mongodb): An exposed MongoDB database is a mongod instance reachable from the public internet (typically TCP 27017) with authentication disabled, so anyone who connects can read, modify, or delete every collection without credentials. It is one of the most reliably exploited data exposures on the internet and a frequent target of automated ransom-wipe campaigns.
- [Exposed Redis Instance](https://www.legba.app/adversary/exposures/exposed-redis): An exposed Redis instance is a Redis key-value server reachable from untrusted networks (typically TCP 6379) without authentication, letting anyone who connects read and overwrite all data and, via CONFIG SET plus SAVE, write arbitrary files to achieve remote code execution.
- [API Keys Leaked in Frontend Code](https://www.legba.app/adversary/exposures/leaked-api-keys-in-frontend): An API key leaked in frontend code is a secret credential (database token, payment secret key, cloud key, or AI provider key) that gets compiled into the JavaScript bundle or source maps shipped to every visitor's browser, where anyone can read it with browser dev tools. Unlike a publishable key meant for the client, a secret key in the frontend grants attackers the same backend privileges your server holds.
- [Missing API Rate Limiting](https://www.legba.app/adversary/exposures/missing-api-rate-limiting): Missing API rate limiting means a reachable endpoint lacks an effective request-frequency bound for a relevant client or operation. Attackers may then automate credential attempts or costly requests. Confirm the deployed policy and observed behavior before calling the control missing.
- [Missing Supabase Row Level Security (RLS)](https://www.legba.app/adversary/exposures/missing-supabase-row-level-security): Missing Row Level Security (RLS) means a Supabase project's public anon key, which is meant to be shipped in browser code, can read or write every row through the auto-generated REST and GraphQL API because no row-level authorization policy gates the request. RLS, not the anon key, is the security boundary, and when it is disabled the entire database is effectively public.
- [Publicly Accessible Cloud Storage Bucket](https://www.legba.app/adversary/exposures/public-cloud-storage-bucket): A publicly accessible cloud storage bucket is an S3, Google Cloud Storage, or Azure Blob container whose access controls let anyone on the internet list or download its objects without authentication, frequently exposing backups, logs, customer records, or secrets.
- [Server-Side Request Forgery (SSRF)](https://www.legba.app/adversary/exposures/server-side-request-forgery): Server-Side Request Forgery (SSRF) is a flaw where an application fetches a user-supplied URL on the server side, letting an attacker coerce the server into reaching internal services or the cloud metadata endpoint (169.254.169.254) to steal credentials. It maps to OWASP A10:2021 and CWE-918.
- [Subdomain Takeover](https://www.legba.app/adversary/exposures/subdomain-takeover): A subdomain takeover happens when a DNS CNAME or ALIAS record still points to a third-party service that has been deprovisioned, letting an attacker re-register that service name and serve their own content from your trusted subdomain.
- [Unauthenticated API Endpoint](https://www.legba.app/adversary/exposures/unauthenticated-api-endpoint): An unauthenticated API endpoint is an internal, admin, or data-handling route that responds to requests without verifying caller identity, letting anyone who finds the URL read or change data the API was never meant to expose publicly.
- [Weak TLS Configuration](https://www.legba.app/adversary/exposures/weak-tls-configuration): A weak TLS configuration is an endpoint that still negotiates deprecated protocols (SSLv3, TLS 1.0/1.1), weak cipher suites, or omits HTTP Strict Transport Security, leaving encrypted traffic open to downgrade and man-in-the-middle interception. It is one of the most common findings on any internet-facing HTTPS surface.

## EASM glossary index

- [What is Asset Discovery?](https://www.legba.app/adversary/glossary/asset-discovery): Asset discovery is the process of finding every internet-facing thing an organization owns or operates - domains, subdomains, IP addresses, hosts, open services, and cloud resources - so that nothing exposed to attackers stays invisible to defenders. It is the first and most decisive phase of external attack surface management, because you cannot protect, patch, or monitor an asset you do not know exists.
- [What is Attack Path Mapping?](https://www.legba.app/adversary/glossary/attack-path-mapping): Attack path mapping is the practice of stitching individually validated exposures into the step-by-step route an attacker would actually walk to reach a high-value asset, so a defender knows not just that a weakness exists but where it leads. It turns a flat list of findings into a prioritized story of how a breach unfolds.
- [What is Attack Surface?](https://www.legba.app/adversary/glossary/attack-surface): An attack surface is the complete set of points on the boundary of a system where an attacker can try to enter it, cause an effect on it, or extract data from it. In practice it is the running tally of every internet-facing host, service, API, credential, and forgotten asset an adversary could reach to get a foothold.
- [What is Continuous Attack Surface Monitoring?](https://www.legba.app/adversary/glossary/continuous-attack-surface-monitoring): Continuous attack surface monitoring is the practice of running asset discovery, exposure detection, and re-validation on an ongoing loop instead of as a one-time audit, so a newly exposed cloud bucket, subdomain, or service is caught hours after it appears rather than at the next quarterly scan. It exists because your internet-facing footprint changes every day, and a point-in-time snapshot is stale the moment a single deploy ships.
- [What is Digital Footprint?](https://www.legba.app/adversary/glossary/digital-footprint): An organization's digital footprint is the complete set of internet-discoverable traces it leaves behind: registered domains and subdomains, internet-facing services and IPs, cloud assets, source-code repositories, leaked credentials, and the OSINT trail of its employees. It is precisely what an attacker enumerates first, because everything they can find without touching your network is free intelligence for planning the breach.
- [What is EASM vs ASM?](https://www.legba.app/adversary/glossary/easm-vs-asm): Attack surface management (ASM) is the umbrella discipline for understanding and reducing the points an attacker could reach across an organization. External attack surface management (EASM) is the outside-in part of that discipline, focused on internet-facing assets and exposures.
- [What is EASM vs CAASM?](https://www.legba.app/adversary/glossary/easm-vs-caasm): EASM discovers internet-facing assets from the outside, including assets absent from internal records. CAASM consolidates internal and external asset data primarily through APIs connected to tools the organization already runs.
- [What is EASM vs CTEM?](https://www.legba.app/adversary/glossary/easm-vs-ctem): CTEM is a continuous program for scoping, discovering, prioritizing, validating, and mobilizing the treatment of exposures. EASM is a capability inside that loop, supplying outside-in discovery and context for the internet-facing attack surface.
- [What is EASM vs Vulnerability Management?](https://www.legba.app/adversary/glossary/easm-vs-vulnerability-management): EASM starts by discovering internet-facing assets that the organization may not know it owns. Vulnerability management starts with identified assets and manages known weaknesses, often through CVE findings, prioritization, patching, and verification.
- [What is Exposure Validation?](https://www.legba.app/adversary/glossary/exposure-validation): Exposure validation is the step of confirming that a discovered exposure is actually reachable and exploitable from an attacker's vantage point, producing concrete evidence rather than a theoretical scanner score. It answers the only question that matters before you wake someone up at 2 a.m.: can this really be used against us right now?
- [What is External Attack Surface Management (EASM)?](https://www.legba.app/adversary/glossary/external-attack-surface-management): External Attack Surface Management (EASM) is the continuous, outside-in discovery, inventory, and risk assessment of an organization's internet-facing assets so security teams can find and fix exposures the same way an attacker would find them. It answers a single, urgent question: what of ours is reachable from the public internet right now, and which of those things are dangerous?
- [What is False Positives in Security Scanning?](https://www.legba.app/adversary/glossary/false-positives-in-security-scanning): A false positive in security scanning is a finding a scanner reports as a vulnerability that, on inspection, is not actually exploitable or present, so it produces work without reducing real risk. Cutting false positives lets a team trust its findings and spend remediation time only on issues that an attacker could genuinely use.
- [What is Passive vs Active Reconnaissance?](https://www.legba.app/adversary/glossary/passive-vs-active-reconnaissance): Passive reconnaissance collects intelligence about a target without ever sending it a packet, by mining third-party data such as certificate transparency logs, passive DNS, WHOIS, and public OSINT, so the target sees nothing. Active reconnaissance probes the target directly with traffic it can attribute to you, for example port scans or live endpoint requests, trading stealth for fresher, ground-truth data.
- [What is Port Scanning?](https://www.legba.app/adversary/glossary/port-scanning): Port scanning is the act of sending crafted packets to a host's TCP and UDP ports to learn which ports are open, closed, or filtered, and then identifying the services and versions listening behind the open ones. It is the foundational discovery step that turns an unknown IP address into a concrete inventory of reachable, attackable services.
- [What is Reconnaissance?](https://www.legba.app/adversary/glossary/reconnaissance): Reconnaissance is the information-gathering phase of an attack or assessment in which an adversary or tester collects intelligence about a target's organization, infrastructure, and people to plan everything that follows. It is the first tactic in the MITRE ATT&CK Enterprise matrix (TA0043) and splits into passive techniques that never touch the target and active techniques that probe it directly.
- [What is Shadow IT?](https://www.legba.app/adversary/glossary/shadow-it): Shadow IT is any device, software, cloud service, or internet-facing asset that runs without the knowledge or approval of central IT and security teams, which means it never lands in the official inventory and never gets patched, monitored, or decommissioned. The job teams actually want done is simple: see every asset an attacker can see, including the ones nobody told you about.
- [What is Subdomain Enumeration?](https://www.legba.app/adversary/glossary/subdomain-enumeration): Subdomain enumeration is the process of finding every hostname that lives under a domain (like staging.example.com or vpn.example.com) so you can see your full internet-facing footprint before an attacker maps it for you.
- [What is Vulnerability Scanning vs Attack Surface Management?](https://www.legba.app/adversary/glossary/vulnerability-scanning-vs-attack-surface-management): Vulnerability scanning checks assets you already know about for known flaws like missing patches and weak configurations, while attack surface management (ASM) first discovers every internet-facing asset you own so nothing gets left unscanned. They are complementary: ASM answers "what do we have exposed?" and vulnerability scanning answers "what is wrong with it?"
