About

Stop fraud, spam, and account takeovers with 99.5% accurate browser fingerprinting as a service. Access suspicious visitor activity and geolocation at lightspeed. Integrate our API into your server-side business rules or signup process. Receive instant notifications delivered securely to your backend systems, ideal for building scalable and asynchronous processes. Powerful account takeover protection for any web application. Keep your customers' accounts safe by accurately identifying threats before they cause damage. Users that re-use passwords across multiple services are at risk of having their accounts accessed by fraudsters who purchased or hacked their account information from elsewhere. Catch these attempts by associating multiple login attempts from bot networks. Social engineering is still one of the most reliable methods for fraudsters to access accounts. Require new visitors to provide additional authentication to stop phished accounts from being accessed easily.

Pros & Cons from Real Users

Pros

  • LinkSentry’s real-time monitoring effectively catches malicious, NSFW, and broken links across our school network’s websites, preventing repeats of past issues with inappropriate content. The javascript snippet was easy to add, and the customizable policies allow precise alert tuning. The dashboards provide clear, actionable insights, ensuring our sites remain secure and trustworthy.
  • I have used broken-link checkers for close to a decade now. I switched to LinkSentry when I realized that it can detect not just broken links, but many more kinds of unwanted content, like links to adult websites, and links that redirect to other sites when visited. Moreover, the tool was able to find many more broken links than previous tools (I believe this is because of the JS library that it uses).
  • LinkSentry continuously monitors external links for security threats, giving us confidence that our site is protected. It’s reliable and does exactly what it promises.

Cons

  • The detailed email reports, while comprehensive, can be overwhelming. A concise summary option would better suit my team's workflow. Considering the Slack integration upgrade for faster alerts.
  • I wish that LinkSentry could do something about the broken links other than flag them to me. Maybe remove them (if possible) or warn my users not to click on them.
  • No major drawbacks so far. Would love to see even more integrations in the future.
