Link Shield

Link Shield offers an API that scans URLs to detect threats such as phishing, malware, scams, and other unwanted destinations. It targets developers building security into their products and workflows, with emphasis on real-time analysis and transparent scoring details.

The API can be integrated into existing stacks using REST endpoints, with a focus on straightforward documentation and simple integration steps so teams can add protection without heavy changes to their systems.

The service returns a risk score for each scanned URL, along with reasons to help teams decide whether to allow, warn, or block a link, and supports redirect-aware detection to uncover hidden destinations.

Real-time scoring, per-link risk scores, and transparent signals are highlighted as core features, with emphasis on quick setup and scalable scanning across batches of URLs.

Use cases

• Score a URL for threats in an app to assess risk before navigation
• Batch-score URLs to pre-screen user-submitted links in a product
• Review and filter links by risk category and score
