Firewall Management · Chichester
Firewall Management in Chichester
Configuring and maintaining firewalls for Chichester organisations. Firewall rulesets decay in a predictable way — rules get added for a project, a supplier or an urgent request, and almost none are ever removed, so after a few years nobody can explain half of what is permitted.
Why this comes up
The problem
The firewall was configured years ago and rules have accumulated since. Nobody knows what several of them are for, and removing anything feels risky.
What you get
What we deliver
- Rule review with each rule traced to a purpose and an owner
- Unused and shadowed rules identified from actual traffic logs
- Removal staged carefully, since deleting a rule nobody understands can break things
- Inbound exposure minimised, because that is where opportunistic attacks arrive
- Firmware kept current, as firewall vulnerabilities are actively exploited
- Change process defined, so the ruleset does not silently decay again

Firewall Management in Chichester — common questions
- How do we remove rules safely?
- By using traffic logs to identify rules nothing has matched in months, then disabling rather than deleting and watching for complaints. Deleting a rule nobody can explain is how a critical integration breaks on a Friday afternoon.
- Does firewall firmware really need updating?
- Yes — firewall and VPN appliance vulnerabilities are among the most actively exploited, precisely because they sit exposed to the internet. An unpatched firewall is a target rather than a defence, and this is a well-documented route into organisations.
- Is a firewall still enough?
- It was never sufficient alone and is less so now. With cloud services and remote work, much of your traffic never passes through it. It remains a necessary control for what it does cover, alongside identity and endpoint protection.
- What causes rulesets to decay?
- No change process and no review. Rules get added under time pressure with no record of why, and nobody owns removal. A simple requirement to record purpose and owner at the point of adding prevents most of the mess.
- Do you work with businesses across West Sussex?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Chichester and the surrounding West Sussex area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Chichester businesses do you usually work with?
- Booking and ticketing for arts and marine operators, built to survive a season that carries the whole year. Beyond that we work across Tourism & Heritage, Agriculture, Marine, Arts & Culture and Retail.
- Do you cover the areas around Chichester?
- Yes — we work throughout South East, including Southampton, Portsmouth, Brighton. Chichester is an urban area of roughly 30,000+, and we take on work across the wider West Sussex region rather than the city boundary alone.
