Remote access,done right.

Site-to-site tunnels, remote-worker VPN, and zero-trust replacements — designed and deployed for the way your team actually works.

What you get

  • Network topology design + documentation
  • Fortinet edge devices with HA pairs
  • MFA-enforced remote access portals
  • Endpoint posture checks before tunnel up
  • Split-tunnel + DNS optimization
  • Quarterly access review + cleanup

VPN is one of those things that feels simple until you're managing it across 50 remote workers, 4 branch offices, and a partner extranet. The wrong design adds friction and exposes attack surface; the right one is invisible to users and audit-friendly. We build for both.

What's in the engagement

The full deliverable.

Site-to-site IPsec tunnels.

Branch offices, data centers, and partner networks connected over encrypted tunnels with redundancy and monitoring. We design topology to minimize hairpinning and maximize app performance.

Remote worker SSL VPN.

FortiClient or native OS SSL VPN, with MFA enforcement, posture checks (is the device patched? is EDR running?), and split-tunneling tuned to your traffic patterns.

Zero-trust network access (ZTNA).

Where it makes sense, we replace flat VPN access with per-application ZTNA — users only get access to specific apps, not the full network. Smaller blast radius if a device is compromised.

How we run it

Auth → posture → tunnel.

Every remote-worker connection passes through three checks: identity (MFA), device posture (patches, EDR), and policy (which apps does this user need?). All before the tunnel comes up.

FAQ

Common questions.

How many concurrent VPN users can the firewall handle?
Depends on the appliance and license tier — we size for your peak concurrent + 50% headroom. A FortiGate 100F handles ~500 concurrent SSL VPN users; larger sites use 200F+.
Should we use VPN or zero-trust?
Both, usually. Site-to-site VPN for branch connectivity is here to stay. For remote workers, ZTNA is the modern direction — smaller attack surface, better performance, easier offboarding.
