Exposed imaging services
DICOM and web viewers left reachable without authentication can leak patient images and metadata, or let attackers tamper with studies.

Securing the systems that keep hospitals running.
Syllion Security protects PACS and medical imaging networks, connected medical devices and the servers behind them. We find the gaps through hands‑on penetration testing, then give your engineers secure remote access to every site they maintain.
- DICOM & HL7 aware
- Safe testing on clinical networks
- Multi‑hospital remote access

Protocols & frameworks we work with
The challenge
Imaging systems were built to share data, not to defend it.
PACS servers, modalities and connected devices often run for years on legacy software, inside flat networks, reachable by too many people. That makes them a favorite target.
Unmanaged medical IoT
Modalities, monitors and gateways often can't be patched or run endpoint agents, so one weak device becomes a path into the clinical network.
Uncontrolled remote access
Shared VPN accounts, open RDP and ad‑hoc vendor tools across many hospitals leave no clear record of who accessed which server, or why.
What we do
Security built for clinical environments.
From a single imaging archive to a network of hospitals, we secure the systems clinicians depend on, without getting in the way of patient care.
PACS & Imaging Security
Assessment and hardening of PACS, VNA, RIS and DICOM viewers, from the archive down to each modality connection.
- DICOM and DICOMweb exposure & access review
- AE Title, TLS and node whitelisting configuration
- Network segmentation for imaging traffic
- Hardening guides tailored to your vendors
IoT & Medical Device Security
Visibility and protection for connected medical devices and building systems that can't run traditional security agents.
- Device discovery and risk inventory
- Firmware, interface and protocol analysis
- Micro‑segmentation and access policies
- Guidance aligned with IEC 62443 practices
Penetration Testing
Manual, scenario‑based testing by specialists who understand clinical systems, scoped and timed to keep care uninterrupted.
- External, internal and wireless network tests
- Web application & API testing (OWASP)
- Medical device and IoT penetration testing
- Clear reports with prioritized fixes and retesting
Secure Remote Desktop
One hardened gateway for your engineers to maintain servers across every hospital, with no open ports and a full audit trail.
- Zero‑trust, per‑server access with MFA
- Session recording and audit logs
- Time‑limited access for vendors & contractors
- Central management across many sites
Secure remote access
Maintain every hospital server from one secure place.
Your team supports PACS and application servers across many hospitals. Syllion replaces scattered VPNs and exposed RDP with a single, controlled path to each server.
No inbound ports at the hospital
Site connectors dial out to the gateway, so nothing new is exposed to the internet.
Least‑privilege, per‑user access
Each engineer sees only the servers they're assigned, protected by MFA and approval rules.
Every session recorded
Searchable recordings and logs show who connected, to which server, when and what changed.
Time‑boxed vendor access
Grant equipment vendors access for a single job; it expires automatically when the window closes.
