Akamai Technologies has beefed up its existing bot management and mitigation services with the acquisition of US startup Cyberfend.
Financial terms of the deal, announced Monday, were undisclosed.
Credential theft and abuse is a significant problem for online businesses and their customers.
Cyberfend s tech is designed to mitigate problems caused by compromised user credentials eg, usernames, passwords, email addresses that leak and become public following data breaches.
Hackers increasingly use these stolen and leaked credentials to log into a wide range of popular web and mobile services.
Credential-stuffing attacks of this type have affected the UK National Lottery and online takeaway firm Deliveroo over recent weeks.
