This Competing School Filter Blocks Only 40 Percent of Pornographic Websites

There’s been some disparaging content about “URL-based filtering” lately – suggesting that it isn’t able to effectively block without over-blocking. At Lightspeed Systems, we understand that while educational content shouldn’t be over-blocked, adult content shouldn’t be under-blocked, either. Schools need to maintain that fine balance – and Lightspeed Systems has built the technology that delivers the balance schools need.

Effective filtering certainly requires more than a static URL list. It also requires more than real-time AI. That’s why we combine our advanced AI and database technology to provide the best filtering available.

Lightspeed Systems is the most effective filter at keeping schools CIPA compliant, protecting students, and empowering IT and teachers to do more with technology.
