SafeSquid Secure Web Gateway is an HTTP proxy and secure web gateway for controlling web access and protecting web applications in reverse-proxy mode. It categorizes websites, identifies applications and applies user-access policies. HTTPS inspection can use an enterprise root certificate or a SafeSquid self-signed certificate. Malware scanning options include a built-in scanner, ClamAV and ICAP or other third-party systems. Data-loss prevention detects configured keyword patterns in uploads and can restrict them. SafeSquid supports Active Directory, OpenLDAP, Kerberos single sign-on and Linux-PAM authentication. It can use DNSBL services and stream logs to remote aggregators or SIEM systems. Deployment can use standard server hardware, a virtual appliance or private cloud, with multiple nodes in load-balanced or failover clusters. Cloud-backed configuration backup keeps version history for up to 365 days. The vendor says it supports Linux and Microsoft Windows. It is sold as an annual subscription with pricing on request, and the FAQ says the product stops working when an annual subscription is not renewed.
