  • VPN Stability (Kerio VPN Client & Server): Historically, updates often break or disrupt VPN tunnels. The 9.4.2 update is noted for refining the stability of the VPN service. It resolves disconnection issues that occurred when the Control server was under heavy load or during specific re-keying intervals. This is vital for remote workforces relying on the proprietary Kerio VPN Client.
  • Security Patches: The most critical aspect of this update is the patching of security vulnerabilities. GFI addressed potential security loopholes (often related to denial-of-service risks and web filter bypass techniques) that were present in 9.4.1 and earlier. Applying this update is necessary for compliance and network hardening.
  • Web Filter & Application Awareness: The Application Aware Layer 7 firewall received database updates to recognize newer application signatures. This ensures that administrators can effectively block or throttle modern streaming and file-sharing applications that may have bypassed rules in previous versions.
  • Kerio Control VPN Client for macOS: This update included specific fixes for the macOS client, resolving issues where the client would fail to establish a tunnel after OS upgrades on the user's machine.
  • Kerio Control 9.4.2 is a network security appliance / firewall aimed at small-to-medium businesses, combining Stateful Packet Inspection, VPN, content filtering, and traffic monitoring in a single product.
