4 of 7Network security & infrastructure
Network security that keeps one breach from becoming ten.
Most serious incidents start small: one phished laptop, one exposed service. What decides the damage is how far an attacker can move next. We design and harden networks so that a single compromise stays contained, and so that you can see it when it happens.
What we cover
Network architecture and segmentation
Separate zones for staff, servers, guests and critical systems, each allowed only the traffic it needs.
Zero-trust access and VPN replacement
Access based on who someone is and the health of their device, not on being connected to the network.
Firewall, switching and Wi-Fi hardening
Configurations reviewed against vendor guidance and CIS Benchmarks, with risky rules removed.
Logging, SIEM and detection engineering
The right logs in one place, and alerts tuned for the attacks that matter to you.
Endpoint and server hardening (CIS Benchmarks)
Secure baselines for laptops and servers that close common attack paths.
Incident readiness and tabletop exercises
A plan for the day something goes wrong, rehearsed with the people who will need it.
How an engagement runs
Assess
We map what you have: devices, connections, access paths and logging.
Design
A target architecture and a list of changes in priority order.
Harden
Changes rolled out in stages, with rollback plans and as little downtime as possible.
Verify
We test the result the way an attacker would, then document it.
What you get
- An up-to-date network map
- A segmentation and access design
- Hardened configurations and baselines
- Detection rules and alert playbooks
- An incident response plan your team has rehearsed
Standards
CIS Benchmarks and CIS Controls, the NIST Cybersecurity Framework 2.0, and zero-trust architecture as described in NIST SP 800-207.
Questions people ask
Do we need to replace our VPN?
Not always. Sometimes limiting what VPN users can reach is enough. We recommend zero-trust access when it reduces enough risk to justify the change.
Can you work with our current IT provider?
Yes. We often work alongside managed service providers: we focus on design, hardening and testing while they keep running day-to-day operations.
Will the changes cause downtime?
We plan changes in stages with a way to roll back, and schedule them in maintenance windows you approve.
