Cybersecurity is a priority for businesses, and as threats become more numerous, defence has to be layered and an important part of this is power – something that can be overlooked, as Eaton explain.
Cybersecurity is no longer a single control or product. Modern defence is layered, interconnected, and only as strong as its weakest dependency. While organisations invest heavily in detection, response and prevention, one foundational requirement is often overlooked: reliable power.
A layered security strategy only works if the infrastructure supporting it stays online.
The layered security model
A practical cyber defence approach spans seven layers:
| Layer | Focus | Example technologies |
|---|---|---|
| Human | Awareness & behaviour | Training, phishing defence |
| Perimeter | Edge protection | Firewalls, gateways |
| Network | Internal visibility | Segmentation, monitoring |
| Application | App-level defence | WAF, patching |
| Endpoint | Device security | EDR, encryption |
| Data | Protection & recovery | Backup, immutability |
| Mission-critical assets | Availability | Power, resilience |
Security tools operate across these layers, but power underpins them all.
Where power fits
Firewalls, servers, storage, backup platforms and security appliances are useless if they lose power. Eaton UPS and power management solutions ensure:
- Security controls remain operational during outages
- Data integrity is preserved during unexpected shutdowns
- Recovery processes can complete without interruption.
In short: no power, no protection.
