Among firms of 100-499 lawyers that figure rises to 85% and among firms of 500+ it is 89%.

The ABA survey found that personal mobile devices such as tablets, laptops and smartphones are now able to access firms’ networks in the vast majority (81%) of cases, 52% of which require pre-approval or have restrictions and 29% have unfettered access.
Large firms of 100 or more lawyers are more likely than others to have a full security assessment by an independent party but nonetheless the number who said they do have an assessment is just 28%. Of those large firms, 34% said they are likely to be asked by a client or potential client for a security audit or verification of their firm’s security practices.
