Hello everyone, I've been wanting to get your thoughts on what we should consider when needing to provide remote access to internal company resources for an extended period. Specifically, which steps in VPN alternatives and two-factor authentication methods meet security standards? Also, which tools or approaches for logging and tracking these accesses are considered best practices? What have your experiences been with this?
What are the secure methods for external access to corporate networks?

Definitely, for reliable and secure remote access to company internal resources, I highly recommend using modern VPN solutions combined with strict authentication methods. In practice, I've had very good experiences with WireGuard—it's not only more performant than many classic VPNs but also offers strong encryption (ChaCha20, Poly1305) with minimal overhead. Alternatively, OpenVPN with TLS 1.3 is a solid choice, especially if you need to support legacy systems.
For authentication, a two-factor solution like TOTP (Google Authenticator, Authy) or even better, hardware tokens (YubiKey), is essential. The YubiKey, with its FIDO2 support, has proven rock-solid for us—even if devices are lost, security remains intact. It's also crucial to regularly rotate access permissions and limit them to the absolute minimum based on the principle of least privilege.
Logging is just as critical: tools like Splunk or the ELK Stack (Elasticsearch, Logstash, Kibana) help centrally monitor access and immediately detect suspicious activity. We’ve also found integrating a SIEM system (e.g., Wazuh) beneficial for real-time anomaly analysis. A well-thought-out log management system with alerting features (e.g., via Slack or Teams) makes the difference between a half-baked security strategy and true compliance.
