Enterprise networks face constant and rising cyber threats. One layer of defence is not enough: you need a comprehensive, multi-layered approach to secures your network from every angle.

This short whitepaper breaks down Peplink’s powerful features and its layered “defence in depth” (Client, Router, SD-WAN, Cloud, Admin) approach to security.

  • Client layer: Closest to the end-user, security at this level focuses on securing devices and access points, with features including Guest Network Isolation and Rogue AP detection.
  • Router layer: This layer includes a Scalable Firewall, Web Blocking, and Intrusion Detection & DoS Protection, all kept constantly secure with ongoing security patches and firmware updates.
  • SD-WAN layer: 256-Bit AES Encryption and Packet Separation secure all traffic, ensuring data integrity and confidentiality.
  • Cloud and administrative layer: Peplink’s InControl, a cloud-based network management platform, enables centralised configuration management and monitoring. It also features advanced password and trust boundary management to enhance security and reduce the effect of any compromise, particularly vital for multi-site and remote deployments.
