Network security and trust infrastructure
We find where your network is vulnerable and build systems you can trust: certificates instead of passwords, control over every connected device, isolation of critical segments.
What we do
Network security audit
Firewall rule review, discovery of exposed services and dangerous configurations. The result is a clear report: what's critical, what's recommended, what can wait.
PKI on HashiCorp Vault
Your own certificate infrastructure: CA hierarchy, keys stored in an HSM, automated issuance and revocation. The foundation for 802.1X, VPN and internal services.
802.1X access control
A network a stranger's laptop can't plug into: EAP-TLS authentication for every device, Cisco ISE, integration with IP telephony and door access.
Isolated environments
Air-gapped networks for critical systems: segments with no internet access, controlled data transfer gateways, protection of industrial networks.
How a project goes
Audit
We look at what you have now and show the risks and bottlenecks.
Proposal
We fix the scope, milestones, timeline and price — no hidden items.
Rollout
We work with a rollback plan and within agreed windows — no surprises for the business.
Documentation
You get diagrams, credentials and runbooks. Ongoing support optional.
Frequently asked questions
Where do we start if we've never had a security audit?
With a baseline audit: within a few days you get a picture of the current state and a prioritized list of risks. That's the starting point for any further decisions.
What is 802.1X in simple terms?
It's a badge for devices: only equipment with a valid certificate can join the network. A stranger's laptop in a wall socket or on Wi-Fi simply won't get access.
Does a small business need PKI?
Usually not — a well-configured firewall, segmentation and a solid VPN are enough. PKI makes sense from dozens of devices upwards, and we'll tell you honestly when you don't need it.
