Appliances leave enterprises with a window of exposure – Cyren eliminates that window of exposure.

Internet security that protects at cloud speed

Widest cloud visibility

By analyzing billions of daily transactions, Cyren achieves unparallelled threat visibility.

Always up to date

As a cloud-native solution, Cyren is always up to date, ensuring you're always protected.

You can't stop what you can't see

Appliances see only a fraction of the global traffic, which inherently restricts their threat visibility.

Updates can't keep up

Appliances rely on update delivery, which significantly delays their response time.
