Frequently asked questions about Clavister

What customers typically want to know before a Clavister project.

What sets Clavister apart from US NGFW vendors?
Clavister is developed and maintained entirely in Sweden and Europe, without backdoors and with a traceable supply chain. Functionally, the platform competes in the NGFW league – stateful firewalling, DPI, IPS, IPsec/SSL VPN and application control are standard. The difference lies in origin, transparency and the sovereignty aspect.
Which Clavister line fits which size of organization?
NetWall covers small sites and medium-sized networks. NetShield is the high-performance range for data centers and providers, including 4G/5G environments. CyberArmour is the hardened platform for military/government-critical scenarios.
How does centralized management work?
With InControl you centrally manage thousands of devices – with zero-touch provisioning and role-based control. InCenter delivers analytics and reporting; NetEye Cloud adds cloud-based security services such as SSL inspection.
Can you migrate an existing firewall installation to Clavister?
Yes. We typically start with a proof of concept, carefully translate rule sets, run in parallel, and then switch over in a controlled manner. The goal is always: no loss of protection level during migration.
What subscription models are available?
There is the Product Subscription Service (updates, maintenance, support) and – building on it – the Security Subscription Service (anti-virus, web filtering, application control). We calculate the right combination per site with you.
Is Clavister suitable for critical-infrastructure / IT security law requirements?
Yes. Logging, reporting and authentication are granularly configurable; the platform is developed entirely in the EU. We help with connecting to SIEMs, audit trails and documentation.
