Support
UNIX Support
Enterprise UNIX infrastructure, purpose-built,
hardened, and backed by specialists.
Generic infrastructure support is abundant. UNIX expertise is not. When your storage appliance, mail platform, or web infrastructure is built on FreeBSD or GNU/Linux, the difference between a generalist and a specialist shows up at exactly the wrong moment.
Prometheus Systems is the specialist option. We design, deploy, and support UNIX infrastructure across ZFS storage, web serving, and email — with the depth to go beyond surface-level configuration and the experience to keep production systems running.
No outsourced support desks.
No generic playbooks applied to your environment.
No dependency on vendors who don't know UNIX.

The case for a UNIX specialist
For organisations running critical infrastructure on FreeBSD or GNU/Linux, the cost of a support gap is not a slow ticket queue — it is downtime, data exposure, or both. UNIX systems reward deep knowledge. Filesystem internals, kernel tuning, jail and container isolation, ZFS pool management, mail transfer agent configuration: none of these are skills that generalise from Windows administration or cloud console work.
Prometheus Systems has operated in this space for decades. We work at the level the platform demands.
What we support
ZFS Storage Appliances
We design and support high-performance, resilient storage solutions using ZFS, the most advanced filesystem available for data integrity, redundancy, and operational efficiency. Whether the requirement is enterprise primary storage, a hardened backup target, or a replicated DR platform, we tailor every deployment to the exact workload.
Web Servers
From high-traffic public-facing sites to internally hosted application platforms, we optimise, secure, and maintain web server infrastructure for maximum uptime and performance. Our deployments are built for scalability from the outset, not retrofitted when load increases.
Email Servers
We specialise in deploying and managing resilient, highly scalable mail platforms: anti-spam, anti-virus integration, transport encryption, and seamless compatibility with existing clients and directory infrastructure. Our email server deployments give organisations complete operational control over their own communication infrastructure, no third-party relay dependency, no opaque filtering pipeline.
Built for production operations
Every engagement is scoped and executed with production requirements as the baseline, not an afterthought.
- Tailored deployments: We do not apply standard templates to non-standard environments. Every deployment is matched to the specific workload, compliance posture, and operational context.
- Proactive monitoring: We implement instrumentation and alerting suited to each platform. Whether that is Prometheus, Zabbix, Nagios, or your existing inhouse platform.
- Hands-on support: Issues are handled by the engineers who built and know the system, not escalated through a tiered support structure to someone reading documentation for the first time.
- Security by default: Hardening, least-privilege configuration, and audit logging are built into every deployment. NOT sold as an add-on.
- Platform depth: FreeBSD jails, ZFS pool and dataset management, Postfix/Dovecot mail stack, nginx and Apache tuning, PKI and certificate management, we operate at every layer of the stack.
Why Prometheus Systems
The UNIX platforms we support (FreeBSD, RHEL, SUSE, and their derivatives) are chosen by organisations that take infrastructure seriously. Our team brings decades of hands-on UNIX experience to every engagement. We have operated storage appliances under production load, managed mail infrastructure at scale, and maintained web platforms through traffic events and security incidents. That operational history is what we bring to your environment.
Platform coverage: The BSD family of operating systems, Redhat Enterprise Linux, SUSE Linux Enterprise Server, Oracle Solaris, and Compatible derivatives
Integration: Existing monitoring stacks, SIEM platforms, directory services, and security tooling
Licensing: Support arrangements contracted to your exact requirements, no fixed-tier packages
