Fortinet Deployment in Portsmouth
Deploying Fortinet firewalls for Portsmouth organisations, where the cutover is the part that needs planning. Replacing the device at the network edge means an interruption, a configuration that has not run in production before and a decision about how quickly you can put the old one back if something does not work.
Why this comes up
The problem
The new firewall was installed on a Friday evening with no way to revert before Monday.
What you get
What we deliver
- Cutover scheduled with a defined rollback and the previous device kept available
- Configuration built and reviewed in advance rather than assembled during the window
- Existing rules translated deliberately, since automated conversion is imperfect
- Site-to-site and remote access tunnels tested before the change, not after
- Subscriptions activated and verified so protection is live from the first day
- Monitoring and logging configured during deployment rather than left for later

Fortinet Deployment in Portsmouth — common questions
- Why does rollback matter so much?
- Because something usually does not work. A configuration untested against real traffic will have gaps — a tunnel that will not establish, an application blocked unexpectedly — and being able to reinstate the previous device turns a crisis into a rescheduled attempt.
- Can rules be converted automatically?
- Partially, and the result needs reviewing. Conversion tools handle straightforward rules and produce approximations of anything unusual, so treating the output as a starting point rather than a finished configuration avoids some memorable Monday mornings.
- What is most often missed?
- Tunnels and remote access. Site-to-site connections and VPN configurations are easy to overlook during a firewall replacement and immediately obvious when they fail, so testing them in advance where possible is time well spent.
- Should subscriptions be checked at deployment?
- Yes, because a device without them routes traffic and inspects nothing. Confirming that filtering, intrusion prevention and antivirus services are active and updating from the first day avoids a period where the firewall is present and not protecting.
- Do you work with businesses across Hampshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Portsmouth and the surrounding Hampshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Portsmouth businesses do you usually work with?
- Port, ferry and defence logistics systems, plus visitor operations for the waterfront attractions. Beyond that we work across Marine & Defence, Ports & Ferries, Higher Education, Retail and Tourism.
- Do you cover the areas around Portsmouth?
- Yes — we work throughout South East, including Southampton, Chichester, Brighton. Portsmouth is an urban area of roughly 240,000+, and we take on work across the wider Hampshire region rather than the city boundary alone.
