Only when combined with a firewall, web filtering and other security tools do today’s popular VPNs provide comprehensive protection for corporate networks.
PRAGUE, May 12, 2021 – GFI Software, a provider of enterprise network security solutions, has released an updated version of Kerio Control 9.3.6, bringing greater stability and control over network connections and support for new Windows and Big Sur platforms. The product provides an answer to the current complex needs of SMBs who no longer rely on VPNs alone to reliably protect their corporate networks, but require additional elements of multi-layered security.
The most important updates within the new release include:
“Exactly one year ago, traffic and demand for VPN solutions skyrocketed as a result of the pandemic and the shift of workers to the home office,” said Jozef Kačala, Sales Engineer for EMEA/APAC at GFI Software. “However, in the meantime, the cyber environment has changed significantly to the point where it is no longer possible to have a secure corporate network without a multi-layered solution. Today, firewalling, web filtering and overall network integrity protection must be added to comprehensive security.”
Used by more than 25,000 customers worldwide, Kerio Control provides strong protection for corporate networks from cyber threats with next-generation firewall, antivirus and anti-malware protection, web protection and virtual private networks. It includes 8 key security features, can handle traffic filtering for up to 7 types of sources, and can filter up to 500 different websites and applications with 99% accuracy.
The solution can also be activated as part of the GFI Unlimited licensing program at no additional cost, where GFI Unlimited customers can combine it with other applications. Or Kerio Control can be purchased as an appliance as a hardware device easily connected to its own network. More at https://www.gfi.com/products-and-solutions/network-security-solutions/kerio-control
