Is SNMP version 2c secure?
SNMP is without a doubt a very useful protocol for the management and monitoring of network devices, servers and applications.

SNMP version 1: the oldest flavor. Easy to set up – only requires a plaintext community. The biggest downsides are that it does not support 64 bit counters, only 32 bit counters, and that it has little security.
Is SNMP v3 more secure?
SNMPv3 is the most advanced and secure version of SNMP yet. With features like user authentication and encryption, you receive a secure user experience unmanted by the previous versions. Using Intermapper for SNMP monitoring helps you take full advantage of the benefits of SNMpv3.
Why is SNMP v1 insecure?
SNMP is inherently insecure because SNMP messages are not encrypted. SNMP isn’t vulnerable because of a bug in the code; it’s dangerous because of how it was originally designed, before the proliferation of networks connected to the Internet.
