❓ Frequently Asked Questions (FAQ)
🔒 What is the difference between a traditional firewall and a NETASQ UTM?
A traditional firewall is limited to packet filtering and network flow control. The NETASQ U250 is a UTM (Unified Threat Management) appliance that combines all security functions in a single device: stateful firewall, IPS (intrusion prevention), IPSec/SSL VPN, antivirus, antispam, web filtering, and application control. This unified approach simplifies administration, reduces costs, and improves the consistency of the security policy.
🌐 How many users can the U250 firewall protect simultaneously?
With its capacity for 400,000 simultaneous connections and a throughput of 8,500 new sessions per second, the U250 can effectively protect between 100 and 500 users depending on traffic intensity. It is perfectly sized for SMEs, regional agencies, industrial sites, or educational institutions. The performance of 850 Mbps with active IPS ensures smooth browsing even under heavy load.
🔐 How does the VPN ASIC work and what are its advantages?
The VPN ASIC is a hardware cryptographic processor dedicated exclusively to encrypting and decrypting VPN traffic. Unlike a software VPN that uses the main CPU, the ASIC offloads the processor and ensures a constant VPN throughput of 190 Mbps with AES encryption without impacting other security functions. This allows you to interconnect your remote sites at very high speeds (ideal for fiber optics) while maintaining the overall performance of the firewall.
⚙️ Is the NETASQ firewall compatible with other network equipment?
Absolutely. The NETASQ U250 is compatible with all standard network equipment (routers, switches, servers, domain controllers). It supports universal protocols like VLAN 802.1Q, static routing, OSPF, BGP, LACP aggregation, and can integrate into any existing network infrastructure, whether single or multi-vendor (Cisco, HP, Juniper, etc.). IPSec VPNs are interoperable with Cisco, Fortinet, pfSense, and other solutions.
🔄 Can I update the NETASQ firmware to Stormshield?
NETASQ U series appliances can receive firmware updates up to certain versions. After the acquisition by Airbus and the creation of Stormshield in 2014, some NETASQ models benefited from migration paths to Stormshield Network Security (SNS). We recommend consulting Stormshield documentation to verify your U250 model’s compatibility with current SNS versions and possible migration procedures.
📊 How is the firewall managed and monitored?
Administration is done via NETASQ Unified Manager, an intuitive web graphical interface accessible from a browser. You can also use the CLI command line via serial console or SSH. The firewall generates detailed logs sent to external Syslog servers, produces customizable automatic reports, and sends email alerts in case of security events. A real-time dashboard allows monitoring of system status, traffic, blocked threats, and resource usage.
🛡️ What threats can the IPS system detect and block?
The NETASQ U250's IPS (Intrusion Prevention System) engine detects and blocks in real time: zero-day attacks (unknown), flooding (DDoS), port scans, SQL injections, Cross Site Scripting (XSS), Trojans, session hijacking, data exfiltration attempts, malicious fragmentation, and application vulnerability exploits. The protection combines contextual signatures and behavioral/statistical analysis to identify emerging threats without pre-existing signatures.
🔌 What accessories are included with the firewall?
This used NETASQ U250 firewall comes with its power cable. The 19-inch rack mounting kit, Ethernet network cables, SFP modules, and serial console cable are not included unless otherwise stated. The firewall can be used directly in desktop mode (placed) or mounted in a rack with compatible 1U mounting accessories available separately.
