What this means for you
The top 3 risks, most serious first.
-
Serious
It’s made abroad, so the FCC’s 2026 foreign-made router rule applies
The RV340 is manufactured in China. The FCC's March 23, 2026 order bans new foreign-manufactured routers regardless of brand.
-
Moderate
Its software has a long record of security flaws
Cisco SMB routers have documented vulnerabilities across the RV series. Cisco's security response is faster than most consumer vendors, but small business deployments often delay patching.
-
Minor
Your internet provider controls its software, not you
The RV340 is often managed by MSPs. Ensure firmware updates are part of the managed service scope, they are not automatic.
Protections it’s missing
Missing 4 of 8. Has 4 only partly.
We check every router for the same 8 protections. Here is how the Cisco RV340 does.
-
Blocks unknown devices from joining
MissingNew devices stay out until you approve them once, even if they have the Wi-Fi password.
Zero-Trust Device Admission -
Locks a device to approved sites
MissingA device can reach only the sites you approve. Everything else is blocked.
Domain Allowlisting -
Guest access that expires
MissingGuests are removed when they leave and need your approval to reconnect.
Guest Auto-Expiry -
Made outside China’s legal reach
MissingNot subject to China’s National Intelligence Law.
Clean Supply Chain -
Keeps smart gadgets away from your computers
PartlyDevices are kept apart, so a hacked smart TV can’t reach your laptop.
Network Segmentation (VLANs) -
Encrypts internet traffic for every device
PartlyTraffic leaving your home is encrypted, even from devices that can’t run a VPN app.
Router-Level VPN -
Separate Wi-Fi passwords per group
PartlyEach part of your network gets its own password.
Granular Password Control -
Watches for attacks in real time
PartlySpots suspicious devices, traffic and known attacks as they happen.
