Preliminary Network Assessment - Firewall

A firewall configuration built on how you actually use your network.

The preliminary network assessment prepares the deployment of your security solutions (next-generation firewall, VPN, segmentation). Our teams start from your existing infrastructure to draw up a consistent configuration plan before commissioning.

The assessment lets you:

• Identify essential network traffic: Internet, applications, remote access, site-to-site links
• Define filtering rules suited to your usage
• Establish a clear network diagram that serves as the basis for the configuration
• Anticipate future needs: remote work, growth, site interconnection

Scope covered by this assessment (standard architecture):

• 1 main site, with 1 firewall or 1 high-availability pair
• 1 Internet access, with a simple failover backup link if needed
• Up to 10 VLANs or zones, DMZ included
• Up to 5 IPSEC tunnels (excluding VTI) to remote sites
• Remote access SSL VPN for up to 50 users, with 2FA
• Up to 100 filtering rules

Deliverables: a remote discovery interview, the matrix of allowed traffic, a network diagram and the configuration plan (zones, rules, NAT, VPN, hardening), written report included.

Why choose it:

• Time savings: a configuration plan ready to apply, without back-and-forth or risk of error
• Better security: a consistent configuration aligned with best practices

Advanced architecture? More than 5 tunnels or VTI tunnels, dynamic routing, several firewalls or sites with firewalls, several load-balanced Internet links, ZTNA, SSL proxy, custom IPS, industrial segmentation, compliance requirements, migration from another vendor: choose the Advanced Preliminary Network Assessment - Firewall, on quote. If the discovery interview shows that your architecture goes beyond this scope, we tell you before going further and offer you the advanced assessment: the price of this assessment is then deducted from the advanced assessment quote.
