Protecting your network isn’t enough to keep cyber attackers at bay. Many attackers are using encrypted traffic to launch attacks on unsuspecting companies. Any companies that use cloud services and online applications need a web security gateway to filter traffic. Web security gateways stop unsecured traffic from accessing a network. Monitoring encrypted traffic is particularly important because it makes up to 72% of network traffic.
Here is our list of the eight best web security gateways:
- Zscaler Web Security
- Symantec Secure Gateway
- Forcepoint Web Security
- Barracuda Web Security Gateway
- Censornet Web Security
- McAfee Web Gateway
- Sophos Web Gateway
