Cisco, Dell, Facebook, HP, Microsoft and Nokia are some of the bigger general technology companies in the initial group, while security firms like Avast, FireEye and Symantec have also pledged support. Telecom giants BT and Telefonica are also aboard. Membership is open to other companies, of course, but they have to be "trusted," share "high cybersecurity standards" and "adhere unreservedly" to the Accord once they sign up.

The first meeting of Accord members takes place during the ongoing RSA Conference (the RSA is also a member), and they're considering joint actions such as common guidelines and "broadly deployed" features.

In theory, this presents a united front where companies work together and assert that cyberattacks are harmful as a whole. "Everyone deserves protection," according to the agreement. With that said, there are issues. To start, there's a distinct lack of specific action at this stage -- it's easy to make general statements of principle, it's another to back those up.

We'd add that there are notable omissions in the current roster, including Apple, Amazon and Twitter. We wouldn't expect Chinese or Russian firms to sign, for that matter. No matter how much they endorse the ideas behind the Accord, there's little they can do to stop local officials from ordering them to weaken security. The Accord is an important start to fending off cyberattacks, but it may need to expand significantly beyond its existing member list to be truly effective.
