More About Clavister AB
Clavister AB focuses on cybersecurity solutions that are deployed in enterprise, telecom, and public-sector environments, with an emphasis on network-centric and identity-aware protection. Its offerings are used to secure traffic at organizational perimeters, between sites, in data centers, and in distributed operational environments, including telecom networks and critical infrastructure. The company positions its product portfolio around firewalls, secure access, and zero trust-aligned capabilities, with deployment models that include hardware appliances, virtual appliances, and cloud-ready implementations to align with varied enterprise architectures.
In enterprise networks, Clavister’s platforms (network security) implement inspection and control of IP traffic using packet filtering, stateful inspection, Deep Packet Inspection (DPI), and application-aware policy models that are standard in the firewall and unified threat management domain. These systems support secure connectivity via Virtual Private Network (VPN) protocols such as IPsec and SSL/TLS-based remote access, enabling site-to-site and client-to-site encryption for branch offices, remote workers, and third parties. Policy enforcement typically integrates with directory and identity management sources through RADIUS, LDAP, or SAML-based federation, which allows role-based and user-aware access control rather than relying only on IP addresses or subnets.
For identity-centric security, Clavister provides capabilities that align with zero trust network access (ZTNA) and identity and access management (IAM) models (zero trust / identity and access management). These elements use authenticated sessions, device posture checks, and granular authorization rules to grant application or network access. Integration with identity providers and multi-factor authentication vendors supports step-up security for sensitive resources. This architecture is applicable for hybrid workplaces and multi-cloud environments where users access workloads hosted in corporate data centers, private clouds, or public cloud platforms.
In telecom environments, Clavister addresses requirements from Mobile Network Operators (MNOs) and communication service providers (telecom security). Its solutions are designed to be embedded as security functions within virtualized network infrastructures, including 4G and 5G deployments. This often follows Network Functions Virtualization (NFV) concepts, where security capabilities are delivered as Virtual Network Functions (VNFs) that can be orchestrated alongside other virtualized network elements. This approach supports scaling and automation for large subscriber bases, and enables service chaining with other network services in Software Defined Networking (SDN) contexts.
Clavister also supports cloud and virtualized deployments (cloud and virtual security), where the same security functions run as software instances on hypervisors or in Infrastructure-as-a-Service (IaaS) environments. This aligns with reference architectures where security is placed at virtual edges, between application tiers, or as micro-segmentation controls in east-west traffic. Integration with orchestration and management frameworks allows centralized policy definition, log collection, and monitoring, with logs typically exported using industry protocols such as Syslog for use in Security Information and Event Management (SIEM) platforms.
For customers that require design guidance and operational support, Clavister offers professional services and technical assistance (security services). These services span architecture design, migration support from legacy environments, high-availability and clustering configuration, and ongoing maintenance. The company also documents interoperability with standard networking technologies and provides configuration guidance for routing, VLANs, high-availability failover, and VPN topologies, which places its portfolio in directories alongside firewall, secure access, Zero-Trust Network Access (ZTNA), Identity Access Management (IAM), and telecom security vendors.
