Regulated-Industry IT, Cybersecurity & Voice Solutions
At Sigma Networks we spend most of our days solving a very specific problem: how to keep highly regulated organisations productive — and out of trouble with auditors. Whether you run a cardiology clinic in Plano, a regional bank in Denton, or a defence subcontractor outside Fort Worth, you face the same headaches: complex rules, relentless cyber-threats, and technology that has a habit of breaking at the worst possible time. We combine managed IT, security operations and encrypted voice under one roof so you only have to make one phone call when something goes wrong.
Why regulated clients stay with us
- One accountable partner. We design, secure and support the network, the servers, the cloud workloads and the VoIP platform instead of handing you a list of “other vendors to chase”.
- Audit hand-holding. Our team prepares the policy binders, collects evidence and sits in on the audit call so you don’t have to explain VLANs to a lawyer.
- Local, round-the-clock support. Our Network & Security Operations Centres are in DFW; when you phone at 2 a.m., you get a Texan, not a chatbot.
- Proven numbers. Last quarter we closed 93 per cent of service tickets the same day and kept network uptime above 99.9 per cent.
The regulations we deal with every week
| Regulation | Typical pain-point | How we tackle it |
|---|---|---|
| HIPAA / HITECH | Encrypting e-PHI during every hop | End-to-end TLS, off-site backups with BAA, quarterly risk analysis |
| PCI DSS 4.0 | Passing the quarterly ASV scan | Network segmentation, automated patching, real-time file-integrity monitoring |
| SEC / FINRA | Email retention & breach reporting | Immutable email archive, 24 × 7 managed detection and response |
| CMMC 2.0 | Writing the SSP & POA&M | Gap analysis, documentation workshop, ongoing log monitoring |
| CJIS | Two-factor for patrol laptops | VPN with MFA tokens, tamper-proof audit trail |
