Threat Intel FAQ

How can I protect my VPN infrastructure from zero-day exploits?

While zero-day vulnerabilities are inherently difficult to defend against, you can reduce the impact by limiting the exposure of your VPN interfaces. Use robust attack surface management to ensure no unnecessary services are public-facing and maintain a rapid patch management cycle. Implementing multi-factor authentication and strict segmentation can also prevent lateral movement if a breach occurs.
