Cisco ISR 881-SEC-K9 vs Cisco 891-K9 + 2 ISPs redundancy



I have main office of 70 people.

Also I have 2 redundant ISP:

One give me 20 mbit/s

Other only 2 mbit/s and it is my backup ISP.

I have some resources in data center and I need a IPSec VPN to it and some other location.

I suppose there will be up to 3-5 IPSec tunnels.

I choose Cisco ISR 881-SEC-K9 with one wan port and 4 LAN switch.

But know I’m looking for Cisco 891-K9.

There is no security bundle for it. But in this router is marked Cisco 891-K9 Security router. Does it support security features like VPNs, ZBF, IOS Firewall, NBAR and IP SLA for ISP redundancy?

Also if my boss will choose chipper Cisco router 881-SEC-K9. Will I be able to organize 2 ISP redundancy on 4 LAN switch port inside VLAN interfaces because there is only one WAN port?

Please help.

I have found it alredy before I went here to ask.

I put here some question to make myself sure about my choise.

May be someone have already configured some of this routers and can relate to me some experience.

It also nowhere about perfomance of this routers for Firewall, VPNs, switching, routing.
