Network security that controls every connection
Your network carries everything that matters. We design and deploy next-generation firewalls, segmentation and secure connectivity across offices, data centres and cloud, with policies your team can actually maintain.
Firewalls, IPS, VPN and segmentation, designed around your environment
We treat the network as a set of trust zones, not a single perimeter. Our engineers design segmentation, deploy firewalls with inspection switched on, and build VPN connectivity that holds up across vendors, ISPs and NAT. Then we clean up the rule base so it stays secure as you grow.
Flat networks let attackers roam
Once inside a flat network, an attacker can reach servers, cameras and finance systems from a single compromised laptop.
Firewall rules nobody understands
Years of exceptions leave rule bases full of 'any-any' entries that quietly undo your security.
Mixed vendors, broken tunnels
Branches running different firewall brands often suffer unstable VPNs because parameters do not match.
What's included
- Stateful and application-aware firewalling
- Intrusion prevention with regular signature updates
- URL and DNS filtering
- TLS inspection with privacy exclusions
- IKEv2 IPsec with NAT traversal
- SSL VPN and zero-trust network access
Our technology partners
We resell, implement and support these platforms. Our recommendation depends on your environment, existing investments and budget, not on a preferred vendor.
How Provision delivers network security
Map traffic
We document who talks to what, across sites, users, servers and cloud.
Define zones
Assets are grouped into trust zones with clear rules between them.
Deploy and inspect
Firewalls go live with IPS, app control and TLS inspection where appropriate.
Audit and maintain
Scheduled rule reviews remove stale access before it becomes a risk.
Can you connect offices that use different firewall brands?
Yes. Cross-vendor IPsec tunnels are routine for us, including FortiGate to SonicWall links behind NAT. Most instability comes from mismatched identities, PFS or lifetimes, which we align during design.
Do we need TLS inspection?
Most malware now arrives over encrypted connections, so inspection improves detection. We apply it selectively and exclude sensitive categories like banking and health portals to respect privacy.
How often should firewall rules be reviewed?
We recommend a formal review every quarter and after any major change. Our managed service includes scheduled audits with a change report.
What is zero-trust network access?
ZTNA grants users access to specific applications after verifying identity and device health, instead of placing them on the whole network like a traditional VPN.
