Akamai announced Wednesday early results of a partnership with the Center for Internet Security and the Department of Homeland Security to offer free malicious domain blocking and reporting services to state, local, tribal and territorial governments.

After five weeks of offering the service, with just under 350 sign-ups, the MDBR service blocked roughly 10 million malicious domains. That is a big figure given how little work it is for governments to implement.

"It takes less than five minutes to point recursive DNS to us," said Patrick Sullivan, chief technology officer.

Sullivan says the long term idea is for DHS to plug specific policies to protect state, local, tribal and territorial governments into the free service.
