Network Security
Controlled paths in, controlled paths across.
Flat networks turn one problem into every problem
A network that lets any device reach any other device is convenient right up until something malicious lands on it. At that point the absence of internal boundaries is the reason a single infected workstation becomes a company-wide event.
Network security work is mostly unglamorous: knowing what is connected, deciding what may talk to what, and making remote access something you grant deliberately rather than something that accumulated.
Scope
What we do at the network layer
We review and maintain firewall policy, separate the traffic that should never mix, secure wireless properly, and replace ad hoc remote access with something you can audit. Where equipment is past support or misconfigured, we say so and give you the options with costs attached.
Firewall policy
Rules reviewed for what they actually permit today, not what they were meant to permit when written.
Segmentation
Separation of guest, staff, server, payment and device networks so a compromise does not travel freely.
Wireless security
Enterprise authentication where it fits, a genuinely isolated guest network, and coverage that does not tempt people into workarounds.
Remote access
Authenticated remote access with multi-factor, replacing exposed remote desktop and shared credentials.
Edge monitoring
Logging from the network edge collected and reviewed, so blocked and allowed traffic both mean something.
Change control
Firewall and network changes recorded with a reason, so the ruleset does not quietly become nobody's responsibility.
What you get
What changes when network security is handled well
- An internal network where a compromise is contained instead of company-wide.
- Remote access that can be granted, reviewed and revoked.
- Wireless that staff use as intended and guests cannot use as a way in.
- A firewall configuration somebody can explain.
A practical note on network security
Segmentation projects touch everything, so they are staged. We agree an order of work that improves security at each step rather than requiring a single disruptive cutover.
How we deliver it
How we deliver network security
Map what exists
Physical and logical topology, rules in place, and what is actually using them.
Design boundaries that fit the business
Segments follow how teams and systems work, so the design survives contact with daily operations.
Implement in stages
Changes are scheduled, reversible and documented, with the ruleset reviewed on an agreed cycle afterwards.
