The traditional security perimeter — an on-prem firewall, a VPN concentrator, a web filter, and separate AV — is expensive to maintain and full of gaps for a hybrid workforce. Modern SMBs are consolidating to cloud-managed security and SASE.
Why the legacy model fails growing businesses
- Hardware ages, and firmware/patching lags — creating a security risk that grows every quarter.
- Remote workers bypass the perimeter entirely — the firewall only protects traffic that flows through it.
- Multiple consoles mean gaps and finger-pointing between vendors during incidents.
- Renewals and licensing sprawl inflate cost without improving protection.
The simplified target state
| From (legacy) | To (modern) | What you gain |
|---|---|---|
| On-prem firewall + MPLS | Cloud-managed Meraki MX + SD-WAN | Remote management, SD-WAN resilience |
| VPN concentrator | Zero-Trust Access (ZTNA) | Per-app access, no broad tunnel exposure |
| Separate web filter / AV | Umbrella SSE (DNS, SWG, CDFW) | Cloud-delivered, protects roaming users |
| Multiple consoles | One Meraki dashboard | Single pane of glass, faster response |
Sellable outcome: block up to 98% of malware with Cisco Talos intelligence, protect roaming users, and reduce OpEx by consolidating boxes and circuits — all managed by IDENETY. See our Cisco SASE guide for the full Secure Connect architecture, and our Zero Trust guide for the identity layer.
Low-risk migration
IDENETY deploys the new edge alongside the old, migrates policy, validates, and cuts over in a scheduled window — no scramble, no extended downtime. Security efficacy figures referenced from Cisco Meraki security materials.
