Who is Certes Networks?
Certes Networks is a network and data security vendor focused on software-defined encryption and policy-based protection for enterprise and government IP networks.
- Policy-based, software-defined encryption for IP networks (network security)
- Data-in-motion protection across Wide Area Network (WAN), Local Area Network (LAN), and cloud environments (data security)
- Segmentation and isolation of application traffic independent of underlying network (zero-trust / micro-segmentation)
- Centralized encryption policy management and orchestration (security management)
- Integration with existing network and security infrastructure for overlay-based protection (network overlay security)

More About Certes Networks
Certes Networks focuses on securing data in motion across IP-based infrastructures, including enterprise WANs, data centers, and cloud-connected environments.
The company’s offerings center on software-defined encryption (network security), which applies cryptographic controls as an overlay that is independent of the underlying network transport and routing.
This model allows organizations to define security policies based on applications, users, or data flows rather than on physical network topology.
In practice, enterprises and public sector organizations use Certes technology to protect traffic between sites, data centers, and cloud endpoints without requiring changes to existing routers, switches, or Multiprotocol Label Switching (MPLS) services.
The solutions are positioned for environments where multiple carriers, shared infrastructures, or third-party-operated networks introduce risk to sensitive IP traffic.
Certes typically operates at or around Open Systems Interconnection (OSI) Layer 3, applying encryption and segmentation to IP flows while remaining transparent to the network control plane.
This approach differs from traditional site-to-site VPNs that are often network-centric and from Transport Layer Security (TLS), which is bound to specific applications.
By enforcing security at the flow or application segment level, Certes technology supports micro-segmentation (zero-trust / micro-segmentation) across distributed networks, allowing organizations to isolate specific applications or tenants over shared infrastructure.
The company’s policy-based architecture generally includes centralized management and orchestration (security management), where administrators define security policies, encryption domains, and key management parameters from a single console.
Encryption policies can be mapped to applications or user groups, and then pushed to distributed enforcement points that apply IPsec or comparable cryptographic protocols at line rate.
This design enables consistent encryption and segmentation behavior across hybrid environments that span on-premises (on-prem) data centers, private networks, and public cloud connectivity.
Certes Networks aligns with enterprise solution categories such as network security, data-in-motion protection, Zero-Trust Network Access (ZTNA) concepts, and security policy orchestration.
Its overlay model is positioned as compatible with multi-vendor network infrastructure, allowing deployment alongside existing firewalls, Software-Defined Wide Area Network (SD-WAN) platforms, and routing equipment rather than replacing them.
For directory and taxonomy purposes, Certes Networks can be categorized under network security, data encryption for IP networks, zero-trust / segmentation overlays, and centralized security policy management for data-in-motion.
