# Integrations

<Note>
  CLI man page: `safesquid-integrations(7)`
</Note>

SafeSquid works with external systems and bundled services. Configure most integrations in the Web UI; some host paths and daemons are appliance packages.

## Directory and identity

* [Integrate LDAP](/admin_guide/infrastructure_and_access/integrate_ldap) / Active Directory — users, groups, LDAP Profiles on Access rows.
* [Kerberos / SSO](/admin_guide/start_here/authentication) — keytab at `/usr/local/safesquid/security/HTTP.keytab`.
* PAM stack `/etc/pam.d/safesquid` for System authentication.
* IP-to-user map: `USER_IP_DB_FILE` in [startup.ini](/admin_guide/start_here/startup_ini) (for example VPN clients).

## Scanning and adaptation

* [Clam antivirus](/admin_guide/security_scanners/clam_antivirus) — local `clamd` socket.
* [SqScan](/admin_guide/security_scanners/sqscan) — built-in in-memory scanner.
* [ICAP](/admin_guide/security_scanners/icap) — third-party REQMOD/RESPMOD services.
* [DLP](/admin_guide/security_scanners/dlp) — upload inspection and OCR scoring.
* [Image analyzer](/admin_guide/security_scanners/image_analyzer) — optional image scoring module.

## Categorisation and feeds

* [SSqore](/admin_guide/infrastructure_and_access/ssqore) — cloud URL categorisation (CCS).
* [Categorize Web-Sites](/admin_guide/policies_and_profiles/categorize_web_sites) — local category overrides.
* [Application Signatures](/admin_guide/policies_and_profiles/application_signatures) / [Content Signatures](/admin_guide/policies_and_profiles/content_signatures) — vendor signature databases.
* [Subscription](/admin_guide/infrastructure_and_access/subscription) — license and activation; gates cloud signature processing.
* See [Cloud / categorisation feeds](/admin_guide/start_here/cloud_feeds) for UPDATE schedule and offline behaviour.

## Network services

* [WCCP](/admin_guide/infrastructure_and_access/wccp) — transparent redirection to the proxy.
* [Proxy chain](/admin_guide/infrastructure_and_access/proxy_chain) — upstream peers and CARP.
* BIND / DNS stubs under the security DNS directory (appliance).
* rbldnsd-style DNS blacklists used with [DNS Blacklist](/admin_guide/filtering_and_privacy/dns_blacklist).
* DNS categorisation zone: `DNS_CAT_ZONE` in startup.ini.

## Operations

* Monit: `/etc/monit/conf.d/safesquid.monit`
* systemd / init: see [Daemon](/admin_guide/start_here/daemon)
* logrotate: `/etc/logrotate.d/safesquid`
* Master sync: `MASTER_IP`, `NEVER_SYNC`, `ALWAYS_SYNC` in startup.ini
