Zero Trust Architecture & Network Access Control (NAC)
Identity-, device- and context-based access with NAC admission control and continuous verification.
Zero Trust • NGFW • SIEM/SOC • ISO 27001
We build enterprise cybersecurity with Zero Trust and NGFW
We unify NAC, Next-Gen Firewall, IDS/IPS, Secure SD-WAN, micro-segmentation and SIEM/SOC monitoring in one architecture—aligned with ISO 27001 and data-protection requirements.

Challenge
Why enterprise network security stays superficial
Undocumented firewall rules: NGFW/VPN policies grow without ownership; shadow rules and access risk increase.
Lateral movement & weak segmentation: Without VLAN/micro-segmentation, OT and office networks share the same plane.
Missing SIEM/SOC threat monitoring: Logs are not collected or correlated; attacks are detected late.
ISO 27001 / privacy compliance risk: Without provable access, log retention and incident response, audits fail.
Approach
We build Zero Trust, NGFW and SIEM/SOC as one security foundation
Hades Elektronik designs Zero Trust access, NAC, NGFW & IDS/IPS, Secure SD-WAN / micro-segmentation and SIEM/SOC monitoring in a vendor-agnostic way. The goal is not installing a box—it is measurable, auditable security architecture.
Capabilities
Cybersecurity and network technical capabilities
Next-Gen Firewall (NGFW) & IDS/IPS Configuration
We configure application-aware NGFW rules, threat signatures and IDS/IPS policies under control.
Secure SD-WAN & Micro-Segmentation
Secure SD-WAN across branches and VLAN/micro-segmentation to constrain lateral movement on critical systems.
SIEM/SOC Log Analysis & Threat Monitoring
Centralized logging, correlation, alerting and SOC processes make threat monitoring sustainable.
ISO 27001 & Privacy-Aligned Security Architecture
Access control, log retention, incident response and evidence readiness built for audit-ready security.
Use cases
Zero Trust and enterprise network security scenarios
SD-WAN for Distributed Branches
Secure SD-WAN, central policy and protected branch connectivity for multi-site organizations.
OT/ICS Plant Cyber Segmentation
Micro-segmentation and controlled bridges separating production/OT from office IT.
Zero Trust Remote Access
Beyond VPN: identity/device-verified remote access with NAC and Zero Trust policies.
Privacy / ISO Audit Readiness
Log retention, access evidence and incident processes prepared for ISO 27001 and privacy audits.

02
Policy
Zero Trust, NAC, NGFW/IDS-IPS and segmentation principles are defined.
03
Deployment
NGFW, SD-WAN, NAC and SIEM integration are applied under control.
04
Testing
Access, isolation, IDS/IPS and incident scenarios are validated.
05
Management
SIEM/SOC monitoring, rule lifecycle and audit evidence are sustained.
Cybersecurity & network FAQ
How is Zero Trust integrated into our existing network?
Identity, device and network policies are defined in stages; NAC and access controls move you toward Zero Trust without breaking the current environment.
Do you work with our existing firewall brands?
Yes. Without vendor lock-in claims, we analyze your current NGFW/firewall estate and improve policy, IDS/IPS and segmentation.
How are SIEM log retention obligations met?
Source logs are centralized; retention, integrity and access controls are designed to policy and privacy requirements.
Can you isolate OT / industrial networks?
Yes. OT/ICS segmentation, micro-segmentation and controlled bridges separate production networks from office IT.
How do you support ISO 27001 cybersecurity criteria?
Access control, logging, incident response and evidence readiness are embedded so controls are auditable.
