Firewall Management
A firewall installed five years ago and never revisited is a device with a rule in it nobody can explain.
Rules accumulate. Somebody opened a port for a project that finished in 2021, and it is still open because nobody knew what it was for. We review what is there and remove what is no longer justified.
Firmware is kept current, which is not optional: firewall vulnerabilities are actively exploited, and an unpatched edge device is the way in that gets used most.
Configurations are backed up, so a failed device is a swap and a restore rather than a rebuild from memory under pressure.
What this covers
- Rule review, with anything no longer justified removed.
- Firmware kept current on a managed schedule.
- Configuration backups, so a hardware failure is a swap.
- Monitoring of the device itself, including its own health.
- Secure remote access for staff who need it, and only for them.
In their words
The up-time of our network and servers is critical to our day-to-day operations. Tech Dynamix has been an intricate piece of our business by providing us with prompt and reliable services. Tech Dynamix can always be counted on to be there when we need them.
Common questions
Can you manage the firewall we already have?
Usually. It depends on the make, and on whether the manufacturer still supports it. If it is past end of support we will tell you plainly, because an unpatchable edge device is not something to leave in place quietly.
How often are rules reviewed?
On a regular cycle, and whenever something changes. The value is in doing it routinely: a review that only happens after an incident is a post-mortem, not a control.
Part of Networking & Infrastructure
Networks that are documented, monitored, and sized for the work you actually do on them.
