Every day an email domain operates without a DMARC enforcement policy, anyone on the internet can send email that genuinely appears to come from that organisation. Mail Sentry is our fully managed email authentication service, driving your corporate domains from initial visibility through to full rejection enforcement on a safe, structured timeline.
p=none through to p=reject, designed to protect your legitimate mail flows whilst shutting down spoofing.Full detail on our email security management is available on the Mail Sentry page.
Every anti-malware engine has a detection gap. Cloud-based multi-engine alternatives close that gap, but at a cost: your files transit an offshore platform you do not own, operate, or fully control. TriDefender is the third option: multiple independent scanning engines running in parallel, inside your own infrastructure, returning a policy-driven verdict in milliseconds. Nothing leaves your network, ever.
SIGHUP, strict per-engine timeouts, and native JSON statistics endpoints for monitoring.Full detail on our anti-malware orchestration capabilities is available on the TriDefender page.
Generic IT support is easy to find. Engineers who understand your infrastructure at a level that prevents problems rather than just reacting to them are not. Prometheus Systems provides hands-on technical services across support, networking, UNIX infrastructure, printing, and enterprise security (with the depth to handle production environments and the experience to keep them running).
No first-level support reading from a script.
No solutions designed around what we have in stock.
No handoffs to engineers who have never seen your environment.
When infrastructure breaks, the cost is measured in lost time. Our support team resolves issues at the level they actually occur (not triaged through a helpdesk that escalates everything).
We service and maintain printing infrastructure across a wide range of hardware, keeping equipment operational and reducing the cost of premature replacement.
Most network problems are design problems. Bandwidth contention, misconfigured firewalls, lateral movement after a breach: these are the predictable result of infrastructure that was never properly architected. We design and build networks that perform under load and close the gaps that matter.
Full detail on our network services is available on the Network Services page.
UNIX systems reward deep knowledge. Filesystem internals, kernel tuning, jail isolation, ZFS pool management: none of these generalise from Windows administration or cloud console work. We operate at the level the platform demands.
Full detail on our UNIX capabilities is available on the UNIX Support page.

| Prometheus Systems builds and supports infrastructure that does not compromise on performance or compliance. Whether we are hardening a UNIX environment, optimising core enterprise networks, stopping malware on-premises with TriDefender, or securing email boundaries with Mail Sentry, our approach remains identical: we eliminate the guesswork, handle the operational detail, and provide direct access to specialist engineering expertise. Your infrastructure stays under your control, and your business remains resilient. |
