How this service works
URL safety & phishing detection
Output
Returns a safety verdict indicating whether the URL is safe, phishing, malicious, or suspicious, along with threat classification details and a risk score based on real-time security intelligence.
Example use cases
Email security screening for finance teams
“I got this payment confirmation email with a link to update my billing info — can you check if https://verify-account-secure.com/billing-update is legitimate or a phishing attempt before I click it?”
User-submitted link validation in chat
“Someone in our community chat shared this resource link — https://download-tools.net/utility — can you run a safety check on it to make sure it's not malicious before we promote it?”
Automated redirect verification in workflows
“Our system is about to redirect users to a third-party integration at https://partner-checkout.io/payment — can you verify that URL is safe and not a phishing or malware threat before we send traffic there?”
