SiteLock is a website security service that scans the customer's website and fixes any existing issues with malware and other vulnerabilities. Afterwards, customers can use the TrueShield firewall to protect their site and TrueSpeed to speed it up. SiteLock also facilitates PCI compliance for sites that accept payments. Once a site is scanned and secured, it can display the SiteLock Trust Seal, which shows end users that they can shop there safely. SiteLock Partners can integrate with SiteLock in several ways, including via REST API.
