Conclusion: The HP M220 has just enough security features and just enough speeds for most small businesses. Simply to set up and easy to manage, the HP M220 is a good, choice if you don't need an exhaustive list of security options and price isn't an object.
Pros: advanced features such as rogue access point detection. Easy setup. Power over Ethernet expands deployment options. IPv6 support.
Cons: Interface feels dated. Menu layout is a little confusing. Cheaper competitors offer faster speeds.
